Is biostimulator a concept of hype? In response, many scholars told reporters that biostimulants are not a concept of hype. In the face of agricultural quality improvement and efficiency requirements, it is necessary for the industry to explore its mechanism of action and give a scientific definition and interpretation of such substances. The survey found that many biostimulant products, including humic acid, amino acids, seaweed extracts, and biomass extracts, have been widely used in China for more than 10 years, but their effects have not been fully appreciated. The real role is also Frequently buried, industrial development is repeatedly suppressed in doubt. The fundamental point is that the mechanism research lags behind commercial promotion, and the industry and farmers are constantly questioning and misunderstanding the products.
From July 6th to 7th, the 2016 China Biostimulant High Level Forum will be held in Beijing. At that time, many authoritative experts including academicians, researchers and professors of the Chinese Academy of Engineering and first-line enterprises of biostimulants at home and abroad will gather in Beijing to interpret biostimulants with scientific attitudes and professional voices, so that the industry can truly get out of concept hype. A strange circle, out of the misunderstood quagmire.
The academic experts invited by the conference have long-term research in related fields, and will conduct in-depth exchanges with the industry on bio-stimulating hormone products from different angles. Bai Youlu, director of the China Society of Plant Nutrition and Fertilizers, will share the classification and mechanism of biostimulating factors and open the fog for the industry. Yang Yuping, director of the Fertilization Technology Committee of the China Society of Plant Nutrition and Fertilizers, will comprehensively introduce the role of biostimulants in improving the quality of fertilizers and help large fertilizers find a shortcut to improve quality and efficiency. Many experts who do professional research on different categories will also be on hand.
Zhang Qisheng, an academician of the Chinese Academy of Engineering and a professor at Nanjing Forestry University, will decipher the industrialization technology of biomass extract and its role in weight loss and efficiency. Li Jun, director of the Microbial Fertilizer Quality Supervision, Inspection and Testing Center of the Ministry of Agriculture, will interpret the classification, mechanism of action of microbial fertilizers and its application in improving the quality and efficiency of large fertilizers, and use scientific methods to control the power of microbial bacteria.
Professors from the College of Resources and Environment of Shanxi Agricultural University will share the application technology and role of humic acid in improving the quality and efficiency of Dahua Fertilizer. With his more than ten years of practice, he is telling us what is the most suitable humic acid fertilizer in China. Li Pengcheng, a researcher at the Institute of Oceanology, Chinese Academy of Sciences, will reveal the main components, mechanism of action and industrialization technology of agricultural chitin and seaweed extracts, helping the industry to discover the vitality from the ocean.
At the meeting, relevant leaders of the Ministry of Agriculture, experts in European and American and domestic biostimulating hormones, and first-line manufacturers at home and abroad will also discuss topics such as bio-stimulant management policy, industrialization and market differences between China and foreign countries.
“Getting more output with less investment.†In recent years, biostimulant products such as humic acid, chitin, fish protein, alginic acid, etc., have been used to boost crop yield and quality. The magical effect of “four or two pounds†has attracted more and more attention from the industry, and the research and development of biostimulating hormones has also caused a wave of enthusiasm.
At the same time, the unclear mechanism of action, the uneven quality of products, and the lack of industry norms and standards are also real problems in such products. Experts suggest that this type of product should strengthen the research mechanism and application technology, promote scientific management, and avoid blindly follow the trend and speculation concept to promote the healthy development of bio-stimulating industry and better serve agricultural production.
The definition of neither pesticide nor fertilizer is still unclear
Inducing factors, growth regulators, plant resistance enhancers, plant potentiators, physiological activators... Biostimulants have long been known for a variety of different titles. What kind of substance is biostimulant? Is hormones the same thing? What is its mechanism of action? There are still many questions to be answered around biostimulants. At the China Bio-stimulant high-level forum held in Beijing a few days ago, many industry experts exchanged and discussed this.
The reporter learned from the forum that there is currently no clear and unified definition of biostimulating hormone. The most cited is the definition given by the European Biostimulant Industry Alliance: Biostimulant is a substance that contains certain ingredients and microorganisms. When applied to plants or roots, the effects of these ingredients and plants are Natural processes play a stimulating role, including strengthening or benefiting nutrient absorption, nutritional efficacy, abiotic stress resistance, and crop quality, independent of nutrients.
"Biostimulating hormones are not new things, like humic acid and microbial fertilizers. They have a long history of application in China, but they are not clearly defined and classified." Gao Xiangzhao, chief expert of the National Agricultural Technology Extension Service Center of the Ministry of Agriculture, said .
Dr. Duan Lulu, the National Technical Committee for the Standardization of Fertilizers and Soil Conditioners, believes that, in a strict sense, biostimulants are neither completely fertilizer nor pesticides. It is on the edge of fertilizers and pesticides. Currently, plant growth regulators in pesticides and functional fertilizer modules in fertilizers are biostimulants.
Although the definition of its identity is still vague, the three points of “physiological activity, non-fertilizer and non-pesticide for plants, and beneficial to plant growth†have become the consensus of biostimulants in the industry. Amino acids, humic acid, seaweed extract, chitin, chitosan, biological bacteria, anti-retroviral preparations, etc. belong to this family.
At the forum, experts also emphasized that biostimulants cannot be confused with fertilizers and hormones – fertilizers provide nutrients to crops, while biostimulants work by affecting plant metabolism.
Small amount of energy but effective weight loss and drug reduction strength should not be underestimated
“Seaweed extract has the characteristics of conditioning soil and can improve nutrient efficiency.†“Biomass extract can adjust soil pH and significantly reduce the incidence of potted cucumber root-knot nematodes.â€... At the forum, many experts used The examples describe and affirm the special effects of biostimulants.
Although it is not a pesticide or a fertilizer, biostimulants can solve problems that cannot be solved by fertilizers and pesticides, especially when plants encounter “physiological diseases†or “meteorological disasters†caused by abiotic stress factors. And its role in assisting the reduction and increase of fertilizers and pesticides should not be underestimated.
Li Jun, director of the Microbial Fertilizer Quality Supervision, Inspection and Testing Center of the Ministry of Agriculture, said that microbial fertilizers can activate nutrients, improve fertilizer efficiency, repair and improve soil, improve soil fertility, and promote the application of grapes, apples and other fruit trees in western regions such as Shaanxi and Gansu. Can obviously increase production, quality, and resistance.
Zhou Jianbin, professor of the Research Center for Material Gas (Liquid) Engineering of Nanjing Forestry University, introduced the results of his many years of research and experimentation - using carbon-based fertilizers and biomass extract fertilizers, it can directly reduce the amount of fertilizers and pesticides, and at the same time repair degraded and polluted soil.
Wang Yuxin, a professor at Shanxi Agricultural University, said that humic acid can release nitrogen, activate phosphorus and stabilize potassium. It has obvious synergistic effect when added to large chemical fertilizers, and can also improve the ability of plants to resist drought, salt and resist heavy metal stress.
"Biostimulants can increase plant stress resistance and resist abiotic factors, regulate and improve water in plants, and promote the absorption, functioning and use of nutrients." Duan Lulu pointed out that the experimental data showed that biostimulating hormone was used. The crop yield increase is at least 5% to 10%, the fertilizer utilization rate is increased by at least 5%, and the pesticide use is saved by 5% to 10%.
Lack of research and understanding, lack of industry norms and standards
Although good efficacy is widely recognized, scientific research on biostimulants is still at the surface. Bai Youlu, director of the China Plant Nutrition and Fertilizer Association, said that at present, bio-stimulating hormone is less researched and applied in China. Just like traditional Chinese medicine, there are few research results on its mechanism of action. In the end, which ingredients work, not too much. Clear, neglected and under-recognized biostimulants need to be dig deeper.
Insufficient scientific research has also created problems for registration management and market regulation. It is understood that the current biostimulators are mostly registered as fertilizers. Among the more than 10,000 fertilizer products registered by the Ministry of Agriculture, about 3,000 to 4,000 are related to biostimulants, accounting for about 35% to 40%.
"Compared to foreign countries, biostimulant products have relatively sound standards in China, such as microbial fertilizers, humic acid fertilizers, etc., but the current methods for the classification and management of biostimulants do not reflect their special functions and actualities. effect."
Gao Xiangzhao said that most of the current biostimulants are classified as fertilizers. Because they can't explain the principle of action, some are forced to be classified as water-soluble organic fertilizers, some are registered as soil conditioners, others are registered as pesticides, and some biostimulants that cannot explain the principle clearly cannot. Get registered. It can be said that at present many people in China do not know enough about their role, and they are also relatively rough in research and development, the standards are vague, and the inspection management is relatively extensive.
"How to establish a unified legal and regulatory system and a sound market access system is also a difficult threshold to cross." Duan Lulu believes that to solve this problem, we must first study the functional mechanism of biostimulating hormones, and also learn from the EU. Management experience.
Can't replace fertilizer synergy to get the best effect
In recent years, biostimulants have shown a rising trend in the EU countries. According to John O'Sullivan, CEO of Atlantis Biotechnology Co., Ltd., the global market value of biostimulants will be 12 from 2013. Billion dollars increased to 2.241 billion US dollars.
Today, the growth of chemical fertilizers and pesticides is imperative. Biostimulators have also shown good development prospects in China. In the face of the increasingly heated biostimulant market, many experts stressed that biostimulants can not replace fertilizers. In the process of promotion and application, we must pay attention to scientific understanding, strengthen research and application, and must not concept hype.
"In the process of promotion, we should pay attention to the concept and basic common sense of biostimulating hormones, avoid mixing it with traditional fertilizers, and avoid excessive hype." Gao Xiangzhao reminded, of course, the most important thing is to let farmers see biostimulating hormones. The practical effect is to study the mechanism of biostimulating hormones with a scientific attitude. Only in this way can standard management, fine production and precise use be realized.
Duan Lulu said that biostimulating hormone is not a panacea for improving crop yield quality. Reasonable fertilizer nutrient supply is the basis for high yield and quality of crops. Biostimulators cannot be used as a single product, but should be combined with crops for healthy cultivation, efficient nutrient management, and efficient soil-crop diagnostic techniques to understand soil nutrient supply and crop demand. This is necessary.
Bai Youlu also suggested that biostimulating hormone is not broad-spectrum, only targeted and preventive. It is better only when it is suitable for biostimulating hormones. Not all plants need it under all conditions, and biostimulators are combined. In large fertilizers, it can make the use of large chemical fertilizers more efficient and better for the environment, which will be an important direction of development.
“China’s research on biostimulating factors lags behind commercial promotion.†Duan Lulu suggested that cooperation between government departments, enterprises and scientific research units should be strengthened, the mechanism of action and application technology research in this new field should be strengthened, and the testing standards of related products should be regulated. And registration standards to further improve and improve the regulatory system for biostimulants. (Wang Tengfei, Liu Zhenyuan)
