A lot of water is generally protected from rain and water. If the water is not drained properly, the soil moisture is too high and waterlogging can easily occur. Drain the drains in time and sprinkle wood ash between the rows to loosen the soil and increase soil permeability.
The two defenses laid back on the plots where the seedling stage had fallen, and ploughed and repressed before the jointing of wheat. In the early stage of the jointing of wheat, after the dew had dried on sunny days, a chlormequat solution with a concentration of 0.2% to 0.4% was sprayed.
Three anti-premature sensible wheat After heading, roots, stems and leaves basically stopped growing. The growth center turned to the panicle, and the organic nutrients produced and stored in stems and leaves were continuously transported to the seeds. This period, often due to lack of fertilizer to premature aging of the leaves, resulting in a decrease in the weight of 1000 grains and reduced production, therefore, timely supplementation. Usually in the wheat booting to the early filling stage, foliar spray nitrogen, phosphorus, potassium fertilizer, to supplement the lack of soil nutrients, extend the leaf functional period. Can be 0.2% ~ 0.3% of potassium dihydrogen phosphate plus 1% of urea solution spray, spray once every 10 days, and even spray 2 or 3 times, spray out of the Qi Ye when the effect is better. Spraying time is best in the evening, it should not be sprayed around noon, if the rain within 8 hours after spraying, to make up the spray.
In the middle and late stages of the four pest-proof wheat, high incidence periods of diseases and insect pests such as scab, rust, sheath blight and aphids have a great impact on yield and quality, and should be prevented and treated as soon as possible.
