Key points of wheat bootie management
At present, winter wheat enters the stage of reproductive growth centered on the growth of ear grains. This is a crucial period for gaining more and more weight. Management should pay attention to the following points:
Timely watering. Wheat needs a lot of water in the later period of childbirth. This period is in the dry season with less rainfall and more dry hot wind. In order to ensure the normal solid grouting of wheat, heading, flowering, and grouting should be well-watered in areas where conditions are favorable after heading to meet the water requirements of wheat.
Prevent lodging. First of all, we must combine the actual selection of lodging resistant varieties with proper close planting, deep plowing and improving the quality of soil preparation, and promote the development of root system before winter and return to the green period, and regulate the population structure. Especially in the jointing period, we must accurately determine the condition of the seedlings, and rationally apply fertilizer and water and chemical regulation. In addition, the irrigation during the grain filling period should pay close attention to the weather and prevent the lodging of water caused by the weather.
Root dressing outside. After the flowering of wheat, during the initial stage of grain filling, the secondary phosphate fertilizer is sprayed, and the dry grain weight can increase by 2 to 3 grams, and the yield can be increased by about 10%. Since the later spraying of phosphorus is beneficial to increase the content of available phosphorus and Sugar in the stems and leaves of wheat, it can promote grouting. The weight of dried grains is increased and the ripening period is advanced. If wheat leaves are yellowish-green after flowering, there are signs of premature death, which can be combined with spraying phosphorus and spraying urea at a concentration of 1% to 2% (do not over-concentrate).
