畦灌
border irrigation

q IgUan畦灌(border irrigation)灌概水在畦面上流动过程中以重力作用渗入土壤的灌溉方法。畦灌方法简单,但要达到定额,均匀灌水,对平整土地的要求较高,必须修建临时渠道和土埂。灌水后,土壤团粒结构易遭破坏,形成表土板结。 畦灌适用于灌溉窄行密植作物,如小麦、谷子、牧草、蔬菜等。适宜畦灌的地面坡度为0.001一0.003,最大可达0 .02。但坡度过大时土壤易被冲刷,引起水土流失。 畦田的长和宽与地面坡度、土地平整程度、土壤透水性、入畦流量及农机具尺寸等有关。入畦流量以保证灌水均匀,不冲刷土壤为原则。通常单宽流量控制在每米3一6升/秒,畦长多采用30一100米,畦宽2一4米,多为农机具尺寸的整倍数。菜田的畦长较短,15一20米,畦宽0.5一1.咪。当入畦流量一定时,对土壤透水性强而地表坡度小者,畦长取小值;反之,则取大值。畦埂高常用0.20一0.25米,地边埂稍高于畦埂。在土地精细平整条件下,畦长也有采用400一500米的。 从末级渠道向畦田供水,可采用虹吸管或灌水管引水入畦;也可用带孔的移动式硬管或软管代替末级渠道,每个孔向一个畦田放水。 畦口的放水时间应根据畦长、坡度、土壤透水性、入畦流量来确定。通常采用畦内水流长度与畦长的比数做为畦口放水时间的依据,如九成改水,即水流到达畦长的90%时,进行封口。封口后,水流将继续向前流动,至畦尾时全部渗入土中。按中国经验,在一般土壤条件下,畦长50米左右的采用八成改水;畦长30一40米,九成改水;畦长30米以下,十成改水。 (朱风书)
