膜下滴灌技术在吉林省的应用研究

膜下滴灌技术是近年来在干旱和半干旱地区广泛应用的一项技术,从吉林省西部近年来的应用推广情况来看,其在节水、改善生态环境和粮食增产等方面效果显著,并显现出对不同区域、不同作物品种的效益机制的反应各有所不同。因此,本文仅基于玉米在膜下滴灌条件下的不同给水条件的生长变化机制研究成果,对原有灌溉制度的相关参数,如灌水次数、灌水强度、灌水时间等进行适应性修正。提出了基于在膜下滴灌条件下,通过调亏灌溉密植补偿效应提高单位产能的灌水机制。结果表明,结合调亏灌溉技术可改变作物的生殖生长特征,提高作物品质和土地容量,实现增产增收。

Research of the application of Drip Irrigation Technology in Jilin Province

Drip Irrigation technology is a widely applied technology in recent years in arid and semi-arid regions.From the application point of view in western Jilin Province in recent years,its effect is significant on water conservation,improving ecological environment and food production,etc.and shows varieties different in different regions ,different reaction mechanisms benefits of each crop.Therefore, this article is based only on maize growth mechanism of change in the results of the different water conditions under Drip Irrigation, the original irrigation system parameters,such as irrigation frequency,irrigation intensity,irrigation time adaptive correction is proposed based on research high density compensation effects of regulated deficit irrigation, temperature ,water,fertilizer coupling effect under Drip Irrigation and other units of production capacity to improve irrigation system.
