After the beginning of spring, wheat began to change from the pre-winter vegetative stage to the vegetative and reproductive stage. During this period, the temperature changed greatly. The rapid development of wheat groups and individuals, the large amount of plant growth, the need for fertilizer and water, It is an important period for the greatest changes in wheat growth and the determination of the level of yield, and it is also a critical period for the management of wheat fields. To this end, based on the investigation and analysis of the wheat crops of the Wheat Research Group of our province, the wheat expert of the expert advisory board of the newspaper proposed to pay close attention to the management of spring wheat fields with a focus on prevention and control.
Experts pointed out that although the foundation of wheat sowing and the current growing situation of the seedlings are generally better, due to the abnormal climate after wheat sowing, there are some problems that cannot be ignored. One is that some wheat fields have a long trend. According to the survey, the wheat fields in the Wangchangchang account for 18.6%. With the temperature rising in spring, the growth of wheat seedlings is accelerated, and the area of ​​prosperous wheat fields is likely to increase further. In the event of a cold and cold invasion, there is a potential risk of freezing damage to large areas. The second is the partial sowing of early, large sowing wheat fields, large groups, individual growth is weak, poor ventilation and light in the field, the possibility of lodging later in the birth period is very likely. The third is that some wheat fields have fast growth in the early stage, large groups, and high nutrient consumption, which may cause defertilization in the middle and later stages. At the same time, due to the recent high temperature in our province and low rainfall, drought conditions in some wheat fields have become more serious. Fourth, due to the high temperature before winter and the large number of winter and winter pests and weeds, the potential hazards of wheat diseases, weeds and weeds are serious.
According to the current wheat seedlings and climate characteristics, especially since the Spring Festival this year, the spring tube is short and has little room for maneuver. Therefore, the guiding ideology for spring wheat field management in our province is to focus on one control and four defenses, that is, to control prosperous growth, prevent lodging, prevent freezing, prevent pests and diseases, and prevent de-fertilizer, highlighting an early word and grasping a good character. The ground should be suitable for seedlings, implement classified guidance, rationally manage the fertilizer, make the wheat seedlings grow steadily, construct a reasonable population structure, increase grain growth and maintain weight, and provide scientific management with yield and benefits. Specific technical measures:
First, repression of cultivator control, inhibition of Mai Miaowang (a) repression. For the current prosperous wheat field with more than 900,000 individual plants, more than 900,000 plant groups, long leaf lengths, and seedling heights of more than 30 cm, or wheat fields that may have prosperous tendencies in the spring, stone buckets and petrol canisters filled with water should be adopted as soon as possible. Foot and other methods to suppress, control prosperous. Especially for wheat fields with extensive land preparation, multitude, or rotation tillage, or large amount of stalks returned to the field, comprehensive suppression must be carried out. When suppressing, it is necessary to grasp the principles of pressure-free drying, pressure-freezing, pressure-freezing, and pressure-free saline-alkali soil. Combining it with cultivator, it is best to press the rake afterwards to make the soil imaginary in order to achieve the effect of raising the temperature of the soil. . In addition, for hilly drylands and wheat fields without irrigation, the repression also has a solid soil, seals cracks, promotes close contact between the soil and the roots, and reduces the effects of water evaporation and lifting. (two) cultivator. Various kinds of wheat fields should be widely cultivated. For wheat fields with prosperous and prosperous tendencies, we must take 2 or 3 times (about 10 days in between) to cut roots, control the growth of the shoots, and promote their growth from strong to weak; for weak seedlings and frozen seedlings In wheat fields with poor root development, shallow-medium tillage and fine-middle-cultivation should be carried out to prevent damage to the roots of wheat cultivars or alfalfa, so as to promote hoeing and eliminate weeds, and to promote the healthy growth of wheat seedlings. (III) Chemical control. For wheat fields with prosperous long wheat fields or wheat fields with obvious growth trends, in addition to deep cultivating and repressing, they can also use 30-40 ml of Zhuangfeng amine per acre or 15% of paclobutrazol wettable powder 30- 40 grams, 30 to 40 kilograms of water sprayed to control the internode elongation at base, enhance lodging resistance.
Second, because of the ground due to seedlings, scientific fertilizer management This year, the type of wheat seedlings is complex. All localities must organize scientific and technical personnel to carry out field investigations and classification of seedlings in a careful manner, so that due to the appropriate seedlings, scientific fertilizer management. For normal growing high-yield wheat fields, 10-15 kg of urea should be applied per acre in the middle and late jointing periods. For wheat fields with poor growth, insufficient base fertilizer or unfertilized fertilizer, urea should be applied at the returning stage to the beginning stage. ~20 kg, to increase the percentage of tillers and spikes, promote the development of small flowers, and increase the number of grains per spike; for flourishing wheat fields, on the basis of repression, deep cultivating and controlling growth, urea is recovered from 10 to 15 per mu in jointing stage to booting stage. kg. The spring wheat field must be combined with watering after top dressing and cultivating in time. For water-irrigated hilly dryland wheat fields, after the soil is thawed in early spring, appropriate quantification fertilizer can be applied after the precipitation is combined with precipitation.
Third, to strengthen forecasting and prevention, picking up pests and weeds for prevention and control in spring is a period when various pests and weeds of wheat are mixed, and it is also a critical period for prevention and control. Due to the high wintering base of this year's diseases, weeds, grasshoppers, and weeds, local governments must strengthen forecasting and forecasting, select appropriate pesticides, and conduct timely prevention and treatment. The focus of wheat pest control this spring is three-disease three-worm. The control of Rhizoctonia solani can be sprayed with 12.5% ​​diniconazole WP in 1,500 times; 12.5% ​​diniconazole WP in strip rust is 15-20 grams per acre. 40-50 kg for spray control; powdery mildew at the beginning of the disease with 20% of Triadimefon EC 1000 times, or 12.5% ​​of diniconazole wettable powder 1500 times spray control. When the spider has more than 200 parasites per 0.33 meters of wheat ridges, it is sprayed with 1500 times of 15% broom nectar, or 4,000 times of 1.8% of Qiqisu EC. The occurrence of wheat midge last year Severe plots emerged in the mid-April of April, and each of the mussels was excavated with 50% phoxim 200 to 300 milliliters per mu, and was distributed in the wheat field. The wheat bran had 500 heads per 100 plants or Crops with 25% glutinous rice were sprayed with 3% acetamiprid wettable powder 2500 times or 10% imidacloprid WP 2000 times. For serious weedy fields, we must do a good job of chemical weed control in wheat fields based on cultivating and weeding. For weeds such as pork bristles, wild rapeseed, mirabilis, and leeks, use 20% of it to make it 50 milliliters per mu, or 72% of superstars to 1 gram per mu, or 70% of wheatgrass net to 70 grams per mu. Control; Monocotyledonous weeds such as wild oats can be used to control 6.9% of hummer 60 ml per mu or 3% of Shima 25 ml. Chemical weeding must pay attention to grasp the amount of application, application time and application methods.
Fourth, as soon as possible to do a good plan, to prevent frost damage in wheat fields, according to the proportion of weak spring varieties area is too large, the status quo of partial wheat growth, and the high probability of occurrence of cold spring in our province, all regions must do early spring wheat antifreeze plan. According to the weather forecast, irrigation should be conducted in time before the cold weather. After the cold has passed, it is timely checked that, for wheat fields that have suffered freezing damage, the combination of water-based fertilizers and quick-acting fertilizers should be used to promote small tillers and new-born tillers to form the ear, thus minimizing the damage caused by freezing damage.
For the treatment of diseases of the Digestive System:
Many symptoms can signal problems with the GI tract, including: abdominal pain, blood in the stool, bloating, constipation, diarrhea, heartburn, incontinence, nausea and vomiting and difficulty swallowing, according to the NIH.
Among the most widely known diseases of the digestive system is colon cancer. According to the Centers for Disease Control (CDC), 51,783 Americans died from colon cancer in 2011 (the most recent year for available data). Excluding skin cancers, colon and rectal cancer, or colorectal cancer, is the third most common cancer diagnosed in both men and women in the United States, according to the American Cancer Society.
Polyp growth and irregular cells, which may or may not be cancerous, are the most common development paths for colorectal cancers (also referred to as CRC), and can be detected during a routine colonoscopy, according to Dr. John Marks, a gastroenterologist affiliated with the Main Line Health health care system.
[The best news is that, if caught early enough, they can also be removed during the colonoscopy - eliminating the possibility that they grow further and become cancer," Marks said.
For those patients whose cancer has already spread, there are various minimally invasive surgical options that have extremely good prognoses. It is recommended that asymptomatic patients without a family history begin getting tested regularly between the ages 45 and 50, according to Marks. [Symptoms which may suggest that you need a colonoscopy at an earlier age include rectal bleeding and stool/bowel habit changes which last for more than a few days."
While CRC gets a great deal of attention, many diseases and conditions of the digestive system - including irritable bowel syndrome, diverticulitis, GERD (acid reflux) and Crohn`s disease - can be chronic and are difficult to diagnose and treat, according to Dr. Larry Good, a gastroenterologist affiliated with South Nassau Communities Hospital. [With many of these diseases, blood work and colonoscopies all looks normal, so there is an absence of red flags."
Many of the diseases of the digestive system are tied to the foods we eat, and a number of sufferers can reduce their symptoms by restricting their diets, Good said. [Of course no one wants to hear that they can`t eat certain foods, but many times, eliminating acidic things from the diet, such as tomatoes, onions, and red wine, can have an impact," Good said.
There are a number of tests to detect digestive tract ailments. A colonoscopy is the examination of the inside of the colon using a long, flexible, fiber-optic viewing instrument called a colonoscope, according the American Gastroenterological Association. Other testing procedures include upper GI endoscopy, capsule endoscopy, endoscopic retrograde cholangiopancreatography and endoscopic ultrasound.
