在我国,冬小麦普遍采用畦灌.根据河北省藁城县灌溉试验站的试验,畦灌用水量较大,单位面积用水量随畦长的增长而加大,畦田的深层渗漏量也随之增大,甚至形成尾部径流,从而导致灌水不均和降低田间水的利用率.因此,近年来当地大力提倡“长畦改短畦”、“宽畦改窄畦”,推广长为5～8～10米、宽为3～5～7米的小畦灌溉方法.为此,我们开展了冬小麦隔畦灌溉试验研究,以解决冬小麦经济用水问题.
In our country, winter wheat is commonly used as shrub irrigation.According to the trial of Tangcheng Irrigation Experimental Station in Hebei Province, the irrigation water consumption is larger and the water consumption per unit area increases with the growth of shrubs, and the depth of leakage of shizuoka also increases , And even the formation of tail runoff, resulting in uneven irrigation and reduce the utilization of water in the field.Therefore, in recent years, the local vigorously promote “long 畦 to short 畦”, “畦 畦 change 畦 畦” to promote the length of 5 to 8 to 10 Rice, the width is 3 ~ 5 ~ 7 meters small 畦 irrigation method.To this end, we carried out the winter wheat paddy irrigation experiment to solve the problem of economic use of winter wheat water.
