干旱是当前农业生产上普遍存在的一个重大问题,对实现农业稳产高产影响很大。“保水”是战胜干旱的基础战胜干旱,从策略上来讲,可以分为两个方面:一是取水,另一是保水。取水就是通过兴修农田水利,如开渠、打井、修水库、截潜流、挖泉水等,充分利用地上和地下的水源,把水浇灌到地里去。保水就是改变土地条件,创造良好的土壤结构,并合理耕作种植,最大限度地保蓄好土壤里的水分,不致造
Drought is a ubiquitous major issue in agricultural production and has a great impact on achieving stable and high-yield agriculture. Water Conservation is the basis for overcoming the drought to overcome the drought. Strategically speaking, it can be divided into two aspects: one is to take water and the other is to keep water. Take water is through the rehabilitation of farmland water conservancy, such as open canals, drilling wells, repair reservoirs, cut-off flow, digging springs, etc., make full use of the ground and underground water, water irrigation to the ground. Water conservation is to change the land conditions, create a good soil structure, and reasonable farming, planting, to maximize the preservation of the water in the soil, not to create
