调亏灌溉是70年代由澳大利亚持续灌溉农业研究所最早提出来的,基于植物生理学和生物化学知识,认为对于有些作物,由于其自身的生理或生化作用受到遗传因素或生长激素的影响,如果在其生长发育某些阶段施加一定程度的水分胁迫,可以增加作物后期的抗旱能力。同时能够引起同化物在不同器官间的重新分配,降低营养器官的生长冗余,提高作物的经济系数,并可通过对其内部生化作用的影响,改善某些作物的品质,起到节水、优质、高效的作用。90年代后期,国内学者开始在大田作物上进行试验,也
Regulated deficit irrigation was firstly proposed by Australian Institute of Continuing Irrigation and Agriculture in the 1970s. Based on the knowledge of plant physiology and biochemistry, it is considered that some crops are affected by genetic factors or growth hormone due to their own physiological or biochemical effects, Some stages of its growth and development exert a certain degree of water stress, can increase the late drought resistance. At the same time, it can cause the redistribution of the assimilates among different organs, reduce the growth redundancy of vegetative organs and increase the economic coefficient of the crop, and can improve the quality of some crops through the influence of its internal biochemical actions, High-quality, efficient role. In the late 1990s, domestic scholars began experimenting with field crops, too
