1. Rape fields are watered or flooded to fight drought. The seedbed should be irrigated one day before the transplanting, so as to avoid cutting off the roots when pulling the seedlings. Seedlings of rape seedlings can be immediately poured into human fecal urine to increase the survival of seedlings and increase the survival rate of seedlings. After the broadcast, the rapeseed field with a slow emergence rate will be irrigated with horse water in a timely manner to facilitate the emergence of seedlings.
2. Wheat field covers rice straw moisture. After the late rice is harvested, it is necessary to cut back and level the land, and the large wheat immediately covers the straw after no-tillage sowing, so that the soil is kept moist, and the early emergence of the wheat is improved and the young seedlings are raised. Where conditions permit, horse water should be furrowed and drought-fighted.
3. Time cultivating and reducing water evaporation. Transplanted rapeseed fields, emerged wheat fields, timely cultivating and weeding, cut off the pores of the soil and reduce the evaporation of water.
4. To promote critical water irrigation and cover-keeping techniques to give priority to satisfying the water supply of fruit and vegetable crops in flowering and fruiting stages. Vigorously promote the techniques of mulching and straw covering to reduce the evaporation of soil moisture and ensure the conservation of earthworms.
5. Add organic fertilizer. The application of organic fertilizer can reduce the amount of water produced per unit of production. Applying sufficient organic fertilizer on the dry land can reduce the water consumption by 50% to 60%. Where the organic fertilizer is insufficient, the straw is introduced to the field to improve the drought resistance of the soil. Appropriate application of chemical fertilizers to increase soil water use efficiency.
6. Use water-saving irrigation techniques. Where conditions permit, water saving micro-irrigation techniques such as drip irrigation and micro-spraying can be applied, and the “micro-storage micro-irrigation†technique can be promoted in high mountains.
In some areas, severe drought conditions have adversely affected the production of winter crops. In order to do a good job of this year's winter production, the experts proposed the following drought-resistant techniques.
