1. Pouring grouting water and topdressing grouting fertilizer
The grain-filling period is the final formation period of wheat grain yield, which has an important influence on the high yield of wheat. During this period of time, wheat has a high demand for water, so it should be combined with irrigation and topdressing with 3 to 5 kg of urea per mu. If there is a rainfall of more than 20 mm during the wheat filling period, the grout water may not be poured. However, if the precipitation during the grouting period is insufficient, you can consider pouring grouting water. For plots with large populations, overgrowth, and lodging tendencies, there is no need to pour grout water or topdressing.
2. Spray foliar fertilizer to prevent dry and hot wind
In the late stage of wheat growth, the absorption capacity of the root system becomes weak. Topdressing wheat leaves can prolong the functional period of wheat leaves, improve photosynthesis, prevent disease and lodging, and reduce the harm of dry and hot wind. In order to increase the thousand-grain weight of wheat and optimize the quality of wheat, it can be sprayed every 7 days: a mixture of 0.4% potassium dihydrogen phosphate and 2 to 3% urea, and other ecologically active fertilizers can also be added to the leaves. Perform spraying.
3. Do a good job in preventing pests and diseases
The grain-filling period of wheat is the key period to increase the thousand-grain weight of wheat, but a variety of diseases and insect pests easily occur during this period. Main control: wheat aphid and leaf blight, head blight, rust, wheat powdery mildew, etc. Early May is a critical period for disease prevention and control. The editor provides farmers with formulas for the prevention and treatment of aphids, powdery mildew, midge, head blight, rust, leaf blight, dry hot wind and other diseases and insect pests:
(1) 3 to 5 grams of 70% imidacloprid wettable powder, plus 25 grams of 45% benzyl prochloraz, plus 98% of 100 grams of potassium dihydrogen phosphate, plus 0.01% 8 ml of brassinolide, plus 80 ml of 4.5% beta-cypermethrin EC.
(2) 8 to 10 grams of 50% nitenpyram wettable powder, plus 30 ml of 25% benzyl propiconazole EC, plus 98% of 100 g of potassium dihydrogen phosphate, plus 8 ml of 0.0% brassinolide, plus 80 ml of 4.5% beta-cypermethrin EC.
(3) 80 ml of 2.5% bifenthrin aqueous emulsion, plus 100 g of 98% potassium dihydrogen phosphate and 10 ml of 48% cyanocynyl tebuconazole suspension.
