Management measures after winter wheat snow and rain
Winter snow and rain are very beneficial to wheat growth, which not only ensures the water supply in winter and spring, but also lowers the temperature after snowfall, which is conducive to the elimination of pests. The main management measures after winter wheat rain and snow are as follows:
First, pay close attention to the work of cultivating and cultivating to make full use of the winter and spring snow and rain. It is especially important to do a good job in the field of spring wheat field cultivation. It can not only increase the temperature and deepen the sputum, promote roots and stagnation, promote early seedling growth, and increase the rate of sub-base formation. Moreover, we can eliminate weeds in the field. In order to prevent the foundation from falling down, we should generally cultivate the crops one or two times. We must deep-cultivate some of the long-growing wheat fields, control them, prevent excessive tillers, over-large groups, and reduce ineffectiveness. Distribution.
Second, postponing the spring water time to the beginning of the jointing stage spring watering prematurely lowering the ground temperature, affecting early development, the root system into the shallow, late is not resistant to drought and easy to fall. The main contradiction affecting wheat during the regreening period is temperature, not water. Therefore, if the wheat field is better, there is no need to pour back the green water, and the spring time is postponed until the jointing period.
Third, comprehensive prevention and control of pests and diseases should be carried out early to comprehensively investigate the pests and diseases, control the occurrence of pests such as larvae, red spiders, wheat leaf bees, rust, Laodelphax striatellus, root rot, and sheath blight, and carry out artificial weeding at the same time. Promote chemical weeding technology, this technology has less labor, high effect and good benefit. It is popular among farmers. Common herbicides include 2.4-DJ ester, benzodiazepine and wheat straw net. The time of application is from wheat to green before the jointing . Farmers should strengthen wheat spring management as soon as possible, promote the transformation and upgrading of wheat seedlings, make full use of winter and spring snow, and ensure the high yield of wheat.
