Wild oats are the vicious weeds of the wheat fields in the Qitaitai field of the Sixth Division of Agriculture in Xinjiang. The impact on the yield of wheat is very large, but the output of wheat is reduced by 20%, while the output of wheat is reduced by 70% to 80%. At the same time, the wild oat seeds can germinate and emerge in the soil for 8 years. Therefore, the prevention of wild oats in wheat fields is very important. We have adopted comprehensive prevention and control measures, namely agricultural and chemical control measures to control wild oats, and achieved certain results. The hazards of wild oats to wheat in wheat and their comprehensive methods for weed control are introduced. I. Agricultural control 1. Voluntary farming or deep plowing in autumn. Before planting winter wheat, it will be ploughed 24 to 27 centimeters. The wild oat seeds will be buried underground, and the wild oats will be basically absent in the second year, which will greatly increase the yield of wheat. 2. Use of autumn rain, easy to emerge weeds, plough to combat grass. After the wheat is harvested, after a heavy rain, the crop will be ploughed and hoeed. It will induce the emergence of a large number of wild oats and other weeds. It will be ploughed from late September to early October. The second year of spring to save the cricket, until the wild oats after the emergence of ploughing, the effect is also very good. 3. Early sowing, timely fertilization, cultivation of strong seedlings, inhibit the growth of wild oats. Spring wheat early sowing, with fertilizer under the seed, can emerge 3 to 5 days earlier than the oats, has a certain inhibition of oats. Timely sowing, with fertilizer under the seed, strong seedlings overwintering, spring return to green than oats early emergence of 7 to 10 days, can effectively inhibit or reduce the risk of wild oats. 4. Rotate with cultivator crops. Planting crops such as wheat, barley, peas, etc., and crop rotations such as corn and sunflower can be used to eradicate wild oats of the current year through cultivators. Green manure or alfalfa can be planted in severe plots, and wild oats can be controlled by castration. 5. Apply cooked manure. 6. If feeds can be made directly from wild oat seeds, they must be crushed and fed to livestock. Second, chemical control (A) soil treatment: 1. Before sowing soil treatment: Before the wheat sowing with chemical herbicide Oats fear the soil, before treatment, the ground leveling to be broadcast, top surface soil per foot 40% Oats Fear Emulsion 200 ml water 50 kg, within 2 hours after application with a disk depth of 10 cm, so that the drug mix. When the soil moisture is poor, use 40% oatmeal 350 milliliters of milk, 50 kilograms of water per acre, and use a 55 sprayer to spray. This prevents the emergence of wild oats during wheat emergence. 2. Post-emergence soil treatment: When winter wheat land is filled with first spring water or spring wheat ground is filled with first water, combined with fertilization, 40% oats acre milk 200 ml and 8 kg urea per acre are mixed, with fertilization, with watering , Prevention of wheat field after pouring the first and second water after the emergence of a large number of wild oats, damage wheat production. (II) Post-emergence shoot and leaf treatment If wild oats are found growing after pouring in the second water of wheat, stems and leaves are used for the treatment, that is, thrips are used for field spraying to eliminate wild oats. After 2 to 3 days after pouring the second water, the relative humidity in the field reaches 80% to 90%, and the best results are obtained. Mu dosage of 6.9% Hammer glue suspension agent 60 ml, artificial spray of 30 kilograms of water. If there are dicotyledonous weeds in the wheat field, such as gray-green pods and self-growing rape, 50 ml of 70% 2 to 4 DJ ester emulsifiable concentrate can be mixed per acre, but the amount of fleas required to reach 70 ml/mu is still 30 kg of water.
