(1) For the vegetative growth of the vegetative plants of the year ago, the soil consumption is too large and there is a phenomenon of “defertilizationâ€. If the population is not large, the total number of stems per acre in the early spring is below 800,000, and the seedlings can be seen after returning green. , get up early in the top dressing watering. If the group is too large, you can top-dress and water. Generally, about 15 kilograms of urea is applied per acre to prevent excessive seedlings from turning weak seedlings. (2) For the excessively prosperous wheat field without de-fertilization, do not rush to fertilize the water in the early spring. Pay attention to repression, ploughing, chemical control and other measures to properly control seedlings and avoid excessive spring tillering. In general, fertilizer should be applied at the late jointing stage. The amount of fertilization is 15 kg of urea. (3) For prosperous wheat fields that suffer from freezing injury, 7 kg of urea should be applied per acre combined with watering in the returning green stage of wheat in early spring, and then urea should be combined with watering at the jointing stage. About kilograms. (4) For a prosperous wheat field without water-flowing conditions, the remediation should be carried out immediately after the soil is thawed in the early spring, so as to raise and protect the crop.
