At present, wheat is in the period of returning green jointing. There is still more than 60 days from large-area harvest. It is an important period for the formation of wheat yield. It is necessary to do a good job in the field management of wheat in the middle and later stages to ensure stable and high yield of wheat.
Qinggou Drainage Because of the many rainy and wet weather in spring, we must do a clean-up work of the internal and external ditch systems so that one side of the wheat field can produce water at the two ends, matching the three ditch, and stopping rain to dry up the land to achieve a bumper harvest.
In the wheat field with a small population and weak seedlings in the jointing stage of panning and nourishing panicle fertilizer, the jointing fertilizer can be properly applied early to increase the panicle-forming spike rate; the wheat field with a large group and normal leaf color should be delayed in the application of jointing and panicle-fertilizer, and the color in the field is obvious. After falling yellow, apply 8 to 10 kg of urea per acre. Once the cold is encountered, the wheat will be quickly applied to nitrogen in the early spring and will promote the early tillering of wheat, increase the tillering percentage of tillers, and reduce the loss of freezing damage.
Prevention and control of pests and wheat in the green jointing stage to control sheath blight, use 5% Jinggangmycin aqueous solution per acre 300 to 400 ml (can add appropriate amount of imidacloprid both aphids and fly locusts), add water 75 kg spray, interval 7 to 10 days for the first Secondary control. From the end of booting to earing stage of wheat, it prevents and controls head blight, and treats powdery mildew. It adheres to the prevention and control principle of “prevention and control of unshakable and prevent from unpredictable for three timesâ€. Each time, it uses 40% of multi-ketone WP 75-100 g per acre. Insect plus an appropriate amount of imidacloprid or pymetrozine control pests. Combine pest control with 0.3% potassium dihydrogen phosphate solution to protect the leaves from dry heat and increase grain weight.
