我国旱地农业高效用水技术体系研究

Study of High Efficient Watering System Applied in the Dry-farmland Agriculture of China

旱地农业在我国国民经济中占有举足轻重的地位。根据我国水资源相对不足的特点,旱地农业用水必须采取综合节水技术,即建立适合我国国情的现代旱地农业高效用水技术体系,主要内容包括适水种植、培育节水高产品种、搞好农田基本建设、土壤改良、蓄水耕作、覆盖保墒、化学调控节水和抗旱灌溉等。

Dryfarmland agriculture plays an important role in our national economy.Owing to the inadequate water resources,dryfarmland agriculture has to take comprehensive watersaving techniques,namely,a high efficient watering system of technology that fits China's situation.This system includes watermoderating planting,breeding of watersaving and high productive plants,basic agricultural construction,soil fining,water storing cultivation,keeping of water in the soil,saving water by chemical adjusting,and antidrought watering.
