At present, as the cold winter continues, the temperature gradually begins to rise, and wheat will enter the green period. We will briefly discuss the management measures in the southern wheat fields from six aspects. First, timely chemical weeding. Wheat fields that were chemically weeded a year ago were less than 10%. Therefore, effective chemical weeding before the Spring Festival after wheat is not jointed is particularly necessary. The methods of chemical weeding are: for broad-leaved weeds, 36% Pentium 5-6 grams per mu watered 30 kg stems and leaves evenly spray; 5.8% per mu with 10 ml watered 30 kg stems evenly spray With wheat straw cover 12 grams per mu watered 30 kg stems and even spray, etc., can effectively remove leek, wild rape and other weeds. For the wild oats of grass weeds, spray 6.9% of the emulsion with 40-60 ml of water and 30 kg of water evenly. Second, the cultivator will warm up and protect the strong seedlings. For the wheat fields with prosperous overwintering periods, deep cultivating can effectively control the growth; for weak seedlings with different conditions, effective shallow-middle cultivating with top-dressing can not only promote multiple spring pods, but also promote the development of wheat roots and ensure the development of wheat. High yield can also play a role in manual weeding. Third, timely application of effective fertilizer. For wheat fields that are sown early and early in winter and have not been managed in time and fertilized when they are sown, they must be robbed, and topdressing 5-8 kg of urea per acre. The weak seedlings and spring festivals for different conditions before winter are used. After the wheat field with poor seedling quality, should seize the opportunity to timely and effective topdressing urea, the amount of fertilizer is generally 8 ~ 10 kg / acre, at the same time, each acre can also be appropriate with 4 to 5 kg of phosphorus and potassium fertilizer, fertilizer should be Watering can be performed in time to ensure fertilizer efficiency. Fourth, early prevention and treatment of sheath blight. With the temperature gradually rising, sheath blight pathogens began to infect wheat strains. The rate of diseased plants increased significantly. During the period of rapid growth of wheat during the rejuvenation period to the jointing stage, wheat sheath blight had a great impact on yield, which generally reduced wheat production. From 2% to 20%, severe plots can reduce production by about 50%, and individual plots can even be eliminated. Therefore, in the period from the turning green stage to the jointing stage of wheat, spraying prevention and control should be carried out according to the development of the disease. Spray can be used 43% Baosui water emulsion, 22.5% diniconazole, etc., can also treat wheat powdery mildew and rust. Fifth, livestock and poultry are strictly prohibited. After the Spring Festival, wheat soon enters the period of re-green jointing. It is also an important period for the simultaneous growth of vegetative growth and reproductive growth of wheat. Livestock and poultry bark production directly reduces production by 6.7% to 21.7%. Therefore, in spring wheat field management, livestock and poultry should be strictly prohibited. Six, to prevent or reduce night frost damage. After the Spring Festival, the temperature rose rapidly and promoted the rapid growth of wheat. However, wheat's ability to resist low temperatures is significantly reduced. Therefore, according to the weather forecast, irrigation methods should be adopted to increase soil moisture, relative humidity, or smoke before the onset of the cold current to effectively prevent or reduce frost damage.
