Spring is the end of the Spring Festival and wheat begins to turn green. This time, we are careful to “pour the spring!†After the arrival of the spring, the temperature generally rises slowly and the wheat begins to turn green and jointing. If the winter comes, the developing wheat will suffer cold damage due to the drop in temperature. Light results in the gradual yellowing of the upper leaves of the wheat, and severely affect the development of the wheat, resulting in a lower seed setting rate, a reduction in the number of grains per panicle, or even a failure of normal heading and death of the seedlings. In order to reduce the harm caused by late spring cold, the following measures can be taken: (1) Use varieties with better cold resistance. 2 Appropriate late broadcast. The late sowing of wheat can appropriately postpone the spring development of wheat and enhance its ability to resist cold and cold. (3) To moderately inhibit growth in excessively prosperous wheat fields, adopt early spring repression, and spray-apply promotion of Huawang No. 3 to properly control wang, which is a simple and easy way to prevent downpour. 4 timely pouring back to Qingshui or get up. Watering the wheat field before cooling to reduce the temperature of the ground. In addition, the soil moisture increases after irrigation, and the thermal conductivity of the soil increases, which increases the soil temperature. Can regulate the microclimate near the ground floor. YT-H706 YT-H706 Shenzhen Sunshine Technology Co.,Ltd , https://www.shenzhenyatwin.com
