With the improvement of people's lives, everyone's requirements for food are getting higher and higher. Green pollution-free vegetables have not been polluted during the planting process, so they meet the needs of the public. The focus of this paper is on the management of green pollution-free vegetables. Key points.
1. Planting techniques for green pollution-free vegetables
1. Seed selection and processing
Planting green pollution-free vegetables When selecting vegetable seeds, we must choose excellent vegetable varieties. This kind of excellent vegetable varieties should have good resistance to pests. Only in this way can we meet the requirements of pollution-free vegetables in planting. Vegetable growers should plan for the cultivation of vegetables and select excellent vegetable varieties with high yield and strong resistance. Before sowing, the seeds should be treated with physical methods and harmless chemical methods, strictly control the spread of seed diseases, ensure the quality of vegetable planting; prepare seedbeds, and choose soil fertile and fertile areas for rational fertilization, soil The use of chemical drugs for disinfection and deworming can reduce the burden of disease prevention and pest control during vegetable cultivation.
2. Seed preparation
Green pollution-free vegetables are not only the control of the use of chemical fertilizers and pesticides, but also have a certain relationship with the nutritional value of vegetables. Therefore, in the usual planting, it is necessary to combine the growth characteristics of different vegetables, and carry out reasonable planting planning according to their respective characteristics. , choose the appropriate planting time period to ensure that the growth requirements such as light, temperature and water supply during the planting period are met.
3. Rational use of chemical fertilizers
One of the requirements for the cultivation of green pollution-free vegetables is to adopt a scientific and pollution-free planting process and cultivation methods to comprehensively ensure the safety and greenness of vegetables. Therefore, before the usual planting and fertilization, it is necessary to first detect the content of various components in the planted soil, and to supplement the missing parts according to a certain ratio. It is also possible to combine the organic fertilizer and the farm organic fertilizer at the same time. Give play to the role of the farmer's organic fertilizer and quickly improve the effect of fertilizer. Moreover, the specific use of chemical fertilizer ingredients must be controlled accordingly. Too much or too little use may have a certain amount of impact on the growth of plants, and even more, it will cause a large amount of waste and environmental pollution. At the same time as the usual use of fertilizer, with a small amount of trace elements can effectively prevent pests. At the same time, when selecting pesticides, the toxicity should be relatively small, and all the fertilizers entering the shed should be treated in a corresponding physical way. High-quality prevention and control should be carried out throughout the planting process to make green pollution-free vegetables more healthy.
4. Disease prevention and pest control technology
Before planting green pollution-free vegetables, it is necessary to select high-yield, high-quality green pollution-free vegetable seeds with good disease and insect resistance, and at the same time adopt reasonable and excellent techniques in planting techniques. Before planting, the land must be ploughed and aired first, then the seeds should be treated in a scientific way and then selected for the best time to plant. At the later stage of planting, attention should be paid to the removal of all kinds of weeds, and for plant-borne diseases and pests. Prevent and manage. In the later stage of plant growth, it is necessary to first construct an environment that is not conducive to the growth of insect diseases in the plantation, and effectively reduce the damage caused by the disease to the green pollution-free vegetables. The plantation must be ventilated in order to reduce the humidity. It can also be used to eliminate pests by means of trapping, to effectively prevent pests and reduce environmental pollution.
Second, the management of green pollution-free vegetables
1. Regional selection of pollution-free plantations
In the development of recent decades, the pollution in the middle and lower reaches of the Yangtze River has become more and more serious. The cultivation of green pollution-free vegetables requires strict environmental requirements. In order to ensure the quality of green pollution-free vegetables, vegetable growers will carefully select suitable planting areas and regions. When choosing a plantation area, be sure to avoid getting close to industrial production areas. The greatest dependence and support of China's rapid economic development in these years is the development of industry. Although the development of industry has made certain developments in China's economy, it has also caused certain impact and damage to China's ecological environment. In areas where construction is relatively dense, the quality of the land is seriously polluted and destroyed, and the cultivation conditions of pure green and non-polluting vegetables cannot be achieved at all. If you plan to grow vegetables in greenhouses, the relevant personnel involved in planting should consider whether the water source in the vegetable growing area is sufficient, the land will not have large pollution, and scientifically and rationally select the planting area to ensure the quality of green pollution-free vegetables to the greatest extent.
2. Soil selection for green pollution-free vegetable cultivation
The middle and lower reaches of the Yangtze River in China are mostly planted in paddy fields. The soil in paddy fields is dominated by acidic soils, and it also meets the demand for the cultivation and growth of pollution-free vegetables. The cultivation of green pollution-free vegetables not only has certain requirements for the planting area, but also has strict requirements for the soil to be planted. When planting pollution-free vegetables, the relevant planters must first test the content of the ingredients in the land to ensure that the ingredients they contain can meet the growth requirements of green pollution-free vegetables. When selecting vegetable growing land, the preferred one should be soil that is more resistant to pests and not contaminated. After the planting land is selected, it cannot be directly planted. It is necessary to carry out certain inspections and small-scale trials on the planting land. If the results of the inspection and trials show that the survey area is suitable for the cultivation of green pollution-free vegetables, then the relevant planting is carried out. . In the early stage of planting, it is necessary to clearly distinguish between green and pollution-free vegetables and conventional vegetables so as not to be contaminated by conventional vegetable growing soils in the later stages of vegetable cultivation. Since the annual precipitation in the middle and lower reaches of the Yangtze River is large, the soil moisture content must be analyzed when testing the planting soil, and the soil water content in the planting area should be controlled within a certain range.
Third, the conclusion
China is a big agricultural country, and the development of agricultural economy plays an important role in China's overall economic growth. China's traditional vegetable cultivation management technology, the economic benefits of vegetable cultivation are not very good, you need to find a new direction of vegetable cultivation. The cultivation of green pollution-free vegetables is a promising agricultural development path. The green vegetables cultivated by using new planting techniques not only satisfy the people's pursuit of green food and green life, but also effectively promote the development of China's economy. China has abundant material conditions and climatic conditions for the development of crops. The development of agriculture has fully utilized China's natural resources. The cultivation and development of green pollution-free vegetables have effectively promoted the development of agriculture and economy in China.
