March coincides with the return to green, jointing, and booting stages of wheat. It is a period when wheat grows vigorously, and it is also a critical period for wheat demand and fertility. Therefore, doing a good job of the wheat barley in March is related to the transformation of wheat seedlings and the formation of wheat yield, which is crucial for seizing the high yield of wheat. 1, scientific watering should be based on soil moisture, combined with seedlings timely timely irrigation suitable irrigation. Irrigation must be done thoroughly, and it is best to use the micro-sprinkler irrigation method for irrigation. 2. Classification of top-dressing joint-fertilizers For late-weak seedling field plots, wheat fields with long-grown depots, and wheat fields with yellowish-yellow leaves and heavily-frozen wheat fields should be reclaimed with 8-10 kilograms of urea as early as possible; In the wheat field, in mid-March (when the first internode of the wheat base is set for a fixed length), top-dressing fertilizer is applied, and 5-8 kilograms of urea is applied per acre; the three types of seedlings that have been topped with green manure, and the groups are too large and growing Wang's field, jointing fertilizer can be postponed until March 20 after the application, generally 5-7 kg of urea Mushi. Topdressing methods: When the sensation is poor, it can be sprayed with micro-spraying; when the lyrical condition is appropriate, it can be applied with the wolfberry; or it can be applied with the wolfberry top dressing or the wolfberry rain. 3, control the anti-fall to the larger group of the plot, in the wheat before and after the start of spraying wheat and other growth regulators to shorten the first internode, control of excessive wheat growth. Overgrown fields can be cut through deep roots to reduce root absorption or repression before jointing to control the growth of stems and shoots on the ground to prevent late lodging. 4. Diseases, pests and weed control (1) Sheath blight: When the diseased plant rate in the field reaches 20% or more, prevention and control can be carried out. Control methods: 20% Jinggangmycin wettable powder 50 grams watered 50 kg spray control per acre, or 15% triadimefon wettable powder 80-100 grams, watered 50-60 kg spray. (2) Golden needleworm: Mu 50% phoxim 250 grams watered 3 kg mixed with dry fine soil (or soybean meal, sesame cake, etc.) 10-15 kg, spread in the field in the evening or before the rain. (3) Wheat spiders: More than 200 insects per municipality have been sprayed on a single row of wheat plants, and 1.8% of insecticides have been used in mu, 6-8 ml of water has been added to 50 kg of water, or 20% of brooms have been added to 20 grams of water and 50 kg of water. Spray control, can also be used 1.8% avermectin EC 3000-5000 times solution (ie 1 ml of watered 3-5 kg ​​of pesticide) spray. (4) Chemical weeding: 20% mu to make it long 20-40 ml water 50-60 kg evenly spray, if wild oats and grassy weeds more fields with tribenuron + Hummer + additives for prevention and treatment, The secondary dilution method was used for chemical weeding on sunny days without wind. The removal time should be controlled before the jointing, to prevent injury after jointing. 5. Prevention of “cold winter†Close attention to weather changes. Once a cold wave strikes and finds that the leaves are dry and the leaves, young ears are immersed in water and other freezing damage, timely nitrogen fertilizers can be topdressed, or potassium dihydrogen phosphate or urea solution can be sprayed. Plant regulators to promote the recovery of wheat. Ginger Herbal Medicine,Ginger Food,Ginger Root,Ginger Powder Yirun Agricultural Cooperative , https://www.yiruncn.com
