First, cover the ditch and keep the wheat field in good condition. When the seedlings are too late to open the trenches, they should open the trenches in time and combine the trenches to supplement the wheat seeds. For example, crop straw, rice bran, bran, etc. can be covered on the surface to ensure soil moisture and increase soil organic matter.
Second, make up the fertilization material and promote the transformation of the seedlings. For those fields where basal fertilizer is under applied or the sowing date is late, fertilizer should be applied early. The tiller fertilizer can be used in combination with wax fertilizer during the wintering period. The wax fertilizer should use high-quality organic fertilizer, and the dosage per acre is about 3 square meters. If no application of wax fertilizer or wax fertilizer is applied in small plots, the time for applying fertilizer in spring should be appropriately advanced. In the returning green period, 4--5 kg ​​of urea should be applied per mu to promote the rooting of the wheat seedlings.
Third, cultivating windrows, breaking knots and increasing ground temperature. After rainfall, irrigation, and early spring season, if the manpower permits, it is advisable to timely carry out shallow-medium tillage for late-seeding weak-field plots, and to prevent the root system from being cut off and the wheat seedlings buried during the delimiting.
Fourth, reasonable irrigation. In the province, wheat is generally not required to be irrigated after sowing until returning to green jointing. However, under conditions of continuous drought and severe shortage of soil moisture, it is necessary to actively fight drought irrigation to ensure the emergence of seedlings and growth. Where conditions permit, high-yield fields can irrigate winter water, which is conducive to keeping seedlings overwintering and the formation of high-yield groups.
Fifth, adopting field management measures to control prosperous growth. Due to the large sowing of wheat and the relatively high temperature in the near future, the problem of prolonged and over-emergence of some plots is likely to occur, which is not only unfavorable to the development of young panicles, resulting in small grains of panicles, but also increasing the risk of lodging and freezing injury. Before winter, repression, deep ploughing can be carried out, and the cultivator can reach a depth of about 10 centimeters. During the start-up period, chemicals such as Maiyefeng, Chlormequat, and Paclobutrazol are used for chemical control; and the application of fertilizer and water is controlled, and the topdressing time is appropriately delayed.
Six, do a good job of prevention and control of pests and weeds. After sowing seedlings, we should pay close attention to using the warm weather before winter to carry out chemical weeding to prevent excessive weeds after spring and prevent difficulties. Pests and diseases should also be forecasted and prevented as soon as possible.
