Field Management techniques of Dryland Wheat in Spring

One is to crack down on the hoe and rake at the top. The combination of suppression and hoe can crush soil blocks, seal cracks, settle soil, increase soil moisture and preserve soil moisture, promote root development and improve the drought resistance of wheat itself. Dingling rake has the same effect, which can break the hardening of wheat field, close the cracks, form fine topsoil layer, prevent wind pumping, frostbite and dead seedlings, and reduce water evaporation in wheat field. In the northwest wheat area, both paddy land and dryland wheat fields should be raked in early spring. After thawing in spring, the soil of Wang seedling field should be deeply ploughed and cut root, and the wild growth should be controlled; the weak seedling field should be hoed shallowly to increase the soil temperature and promote the weak seedling to become strong. The second is to take advantage of soil moisture and fertilize in early spring. Using chemical fertilizer or opening ditches to apply nitrogen fertilizer after soil returning to pulp or light rain in early spring has a prominent effect on increasing the number of ears per mu and grains per ear, grain weight and yield. Those who do not apply phosphate fertilizer should apply diammonium phosphate to nitrogen fertilizer.
