Three methods for increasing wheat grain weight during grouting

The first method: control nitrogen fertilizer in the medium term. Controlling the amount of nitrogen fertilizer in the mid-term wheat field is an effective measure to increase the ratio of carbon to nitrogen in the plant, promote vegetative growth to reproductive growth and transfer, early heading, and prolonging grouting time.
Second Law: Pay attention to late watering. In particular, the grouting water should be poured well. Watering can not only reduce the temperature of the ground, prevent the damage of dry hot air, but also prevent premature root failure, reaching the purpose of water rooting, root protection, and leaf protection. The time for watering slurry should be 10-15 days after heading. The amount of water should not be large. For sandy loam with poor water retention, watering for 10 days should be followed by filling with buckwheat water to keep the ground dry and the effect of increasing grain weight is better.
The third method is to reasonably apply fertilizer and prevent pests and diseases in a timely manner. In order to maintain the appropriate level of nutrition in the plant, avoid premature aging of defertilizer, affect the grouting, attention should be paid to the top dressing. The best effect is to spray the leaves. The method is to spray 1%-2% urea solution or 0.2-0.3% potassium dihydrogen phosphate solution 40-50 kilograms per acre after flowering to the initial stage of grain filling, and can also be mixed and used. Rust, powdery mildew and aphid are the main diseases and pests of wheat fields. They have the greatest damage to wheat grouting and should be used sooner or later as soon as possible. Dimethoate can be used after heading. In order to avoid repeated spraying, pest control and foliar spray can be carried out once. Fertilizers can be mixed and sprayed to save labor and labor. The specific methods are: 20% triamcinate per acre 100 grams, 40% dimethoate 50 grams, urea 0.5 kilograms, potassium dihydrogen phosphate 100 grams, detergent 2.5 grams (do adhesive), 40-50 kilograms of water mix Evenly, after spraying to the initial stage of grouting, it can achieve the purpose of a multi-effect spray, which is beneficial to increase the grain weight.
