Wheat will enter the stage of rapid growth and development, and the key period of wheat returning to green and topdressing will also come. Most farmers arbitrarily increase the amount of reclaimed green fertilizer when topdressing, causing wheat to fall and reduce production. In the process of topdressing, it should be classified according to different seedlings. In general, late seedlings and weak seedlings should be re-fertilized to increase the rate of tillering and panicle formation; strong seedlings should be less or not. Generally, 20 kg of three-element sulfur-based compound fertilizer is applied per mu, and 800 times of new high-fat film powder is used to improve super fertilizer efficiency. For the wintering period, the individual develops well, and the moderately strong seedlings are less or not applied. The main control is to control the jointing fertilizer to reduce the breeding of ineffective tillers in spring, prevent ridges from closing, and is conducive to ventilation and light transmission. In addition to controlling the fertilizer and water during the regreening period, measures such as deep ploughing and physical regulation should be taken to control the growth and spread of wheat roots, stems and leaves, and the flower king 3 is forced to vigorously recirculate the toppings. The inertia advantage of the tip is rapidly weakened to the capping situation. The main nutrient of the trunk turns to the young fruit development system, which enhances the fruit's swelling vitality, avoids the phenomenon of leaf hypertrophy, and improves the field permeability.
Soil fertilization, sand land due to "small seedlings do not send old seedlings." If the fertilizer is poor and the water retention is poor, it should be applied more properly. If the fertilizer is insufficient, it will have a certain impact on the number of spikes and the number of grains and the growth in the later stage. Because the clay soil exerts poor performance in the early stage, it should be applied less during the greening period. At the booting stage, the external application of the root can be applied at the right time to spray the strong ear, which can improve the quality of crops, fertilization, grouting and increase the 1000-grain weight. Should pay attention to not too much fertilization to prevent corruption and lodging. In the drought, fertilize water in time to increase the utilization rate of fertilizer.
