High quality and high yield supporting cultivation techniques for wheat

First, the quality of the seed varieties that are approved by the Provincial Seed Evaluation Committee or approved by the provincial and county agricultural departments are suitable for local cultivation. High-yield, disease-resistant, and good breeds can be treated as headed varieties.

Second, complete dehumidification of wheat field blocks to do a good job of moisture removal work, especially the no-tillage cultivation of the field must be thoroughly dehumidified, so as to avoid damage caused by wet grass, pests and waterlogging caused by late yellow leaves, photosynthesis weakened And affect the wheat production. Therefore, in the production layout as far as possible to achieve "wheat uphill implementation of drought reform, rape seedlings Shiedao early planting." Drainage ditch requirements every 4 meters wide 1, 13 to 15 cm wide, ditch depth 30 cm, open Into a deep narrow ditch, but also pay attention to good back ditch, so that the ditch and trenches connected, the rain only dry Tiantian water.

Third, no-tillage in addition to wheat no-tillage cultivation is an effective measure to save labor, increase production and increase income. In the 15th and 20th days before sowing, the plate field armpits were carried out. The purpose was to make the sun slit in the dens and leach the water in the nest. If the side of the cocoon is sown and the weather is still rainy and cloudy, it can easily make the seed rotten, affect the germination, emergence (Sha Tin can be side to side broadcast). There is no need for armpits in the no-tillage on-demand planting. However, after the planting, straw must be returned to the field to cover the seeds and not to see the soil. Chemical weeding should be done 10-15 days before sowing, mu (1 acre = l/15 hectares, the same below) with Roundup 200 ml or 2-3 seconds without sowing without trace 200 ml of water to 45 kg. Spray evenly with a hand sprayer.

4. Rice straw-covered wheat-covered wheat is a “fertile soil project” that has been implemented in recent years. Its purpose is to maintain the temperature in the field and increase the rate of emergence; second, to suppress the growth of weeds and to reduce the harm caused by rats and birds; and thirdly, to use straw. The method of returning land to improve the soil and improve the quality of crop products. The specific method is to cover the rice straw section 20-30 cm long after wheat sowing, about 300 kg of straw for straw, and not to see the soil for rice straw.

5. Seed coating The use of wheat special seed dressings for seed dressing to improve seedling ability of wheat, effective spike, dwarf plant height and increased seed setting rate. If the "Changquan" brand seeding thorn, mu 50 grams of water plus 250 ml, stir well, you can mix 6-7 kilograms of wheat seed, mixed with a small amount of mud after the paste, and then coated with calcium magnesium phosphate fertilizer, while mixing side wrapped Side broadcast.

Sixth, specification seeding adopts 10X20 centimeters specification, guarantees 30,000 sow nests, sows 6 seeds per litter. Mu of sowing 9 kilograms (6 kilograms of good variety sowing can be), the implementation of "small nests, sparse plant, dense plant."

7. Early sowing in various places should be based on species characteristics, climate characteristics, etc., as early as possible in the appropriate sowing time sowing, so as to facilitate high yield.

Eight, formula fertilization Wheat to high yield, formula fertilization is critical. A fertilizer for the bottom of the boat is 50-60 lbs of human excrement, 30 kg of compound fertilizer or multi-effect fertilizer, and 30 kg of ammonium bicarbonate can also be used for human and animal excrement 50, and 30 kg of phosphate fertilizer is used as base fertilizer. Immediately after the wheat is out of the needles, urea 7.5-10 kg, potassium chloride 10 kg, farmyard manure 30 wolves, and promote early onset. In the early part of the tillering stage and the booting stage, 3 grams of “Shifengle” high-efficiency and powerful fertilizer was used to increase the effect of increasing the panicle and seed setting rate of wheat. In the early stage of flowering, 100g of potassium dihydrogen phosphate was used per mu and 100g of boron was added as the root. Top dressing, Yang Hua to the beginning of the grain filling with 100 grams of potassium diphosphate, spraying, can increase grain weight, increase production.

Nine, full prevention and control of pests and diseases at the end of delivery should pay attention to the prevention of sheath blight, powdery mildew, rust, late joint prevention rule to prevent wheat head blight, seedling and filling period should pay attention to control of locusts. Rhizoctonia with 100 grams of Jinggangmycin; powdery mildew and rust with 25% of Triadimef 30 grams; Maiyuan spider with 20% of insecticidal emulsion 30 grams of Mu; pests with 10% imidacloprid wettable powder mu Twenty grams; Gibberella alternately used thiophanate-and multi-inolin, 150-200 grams per mu, all of the above agents were hand-sprayed with 45 kg of water. In addition, the control of the above pests can also choose other new pesticides on the way.
