The recent warming up of the temperature has brought wheat into the green period and it has grown rapidly. However, the weather is fine and rainless. Some wheat fields have shown signs of drought, which has affected the growth of wheat. Many farmers’ friends began to prepare fertilization and watering. Remind peasant friends to accurately grasp the first time of spring watering and watering, according to drought conditions and seedlings and weather, according to local conditions to grasp the first time the fertilizer. First, the time for seeing the lyrical spring and water should be determined according to soil moisture. Any wheat field with poor quality of soil preparation and serious field loss, wheat field with poor soil preparation and poor individual development and serious drought in the field should be poured in time to return to Qingshui, returning to water for protection of seedlings in the green period. Pay attention to the plan after pouring, so as to improve the quality of your life. Returning green manure can effectively promote the growth of wheat, increase the tillering in the spring and promote the emergence of the ear. Returning Qingshui is suitable for wheat fields with severe drought conditions, and returning green manure is suitable for under-populated wheat fields. In drought-stricken wheat fields, the first water and fertilizer management in spring can be conducted during the jointing stage of wheat. Fertilizer and water management at jointing stage can accelerate the size and polarity of wheat in the wheat field, promote the differentiation of florets, make the flag leaves broad and robust, and improve the ability to resist premature aging, which is conducive to the cultivation of reasonable groups and robust individuals. It is of significance for the formation of a reasonable number of ears per mu and grains per spike. major. Second, see seedlings do not poured back to Qingshui but also according to the situation. For wheat fields planted before the winter, due to lack of soil fertility, the number of tillers is small, and the number of panicles is not enough (about 500,000 total stems per acre before winter). It can be poured back to Qingshui and combined with urea 7.5 to 10 kg per acre. , To promote early spring tiller production, fight for more panicles as much as possible, lay a good foundation for high yield; late sowing of wheat and total stem number of 700,000 to 900,000 strong seedlings or more than 900,000 bitumen seedlings, water is generally sufficient to not turn green Water is mainly cultivated by cultivating loose soil and maintaining earthworms. Winter wheat fields with prosperous growth before winter are consumed by fertilizer and water due to large amounts of growth before winter, and are not irrigated with frozen water before winter, and the field moisture is poor. Attention should also be paid to timely pouring back to Qingshui. Insufficient population In wheat fields, we must pour up water and apply body fat. The fat and water during the growing stage does not increase the total amount of tillers, but it can increase the percentage of spikes and thus increase the number of mu ears. Therefore, the fertilizer and water during the start-up period are suitable for wheat fields with insufficient population, wheat fields with severe drought conditions, and wheat fields that have weakened during the pre-winter season. For moderate or large populations suitable for wheat, the water and fertilizer management will cause the groups to be too large, the internodes are too long, the central leaves are too large, easy to lodging, and other adverse effects, and therefore should not be used, and wheat fields that have been poured back to Qingshui should not be suitable. use. Third, look at the weather pouring spring water, in the daily average temperature above 3 °C can be carried out. Generally, as long as the lyrics permit, the wheat field should delay or not return to Qingshui, delaying the arrival of spring and water until the time of getting up or jointing. After watering, ensure that the wheat field is in good condition when it is suitable. Fourth, the amount of water should not be small when large watering should be strictly controlled watering. Due to the large temperature changes in early spring and late evening, and the frequent change of cold and warm air flow, it is advisable to use small water for watering to prevent the growth of wheat after watering.
