开沟自流结合泼浇陕西省兴平县杨陵公社夏家沟生产队、马嵬公社界庄管区采用的“开沟自流结合泼浇”,就是一个很好的省水省时间的灌水方法。就是:在畦间宽行麦垅里,每隔四到五米冲沟引水灌溉,再用人工以长柄杓辅助左右泼浇,每亩灌水十立米,较自流灌溉45立米节约水量三四倍,这种灌溉方法的灌水量虽然不大,但是对小麦的生长发育效果仍然十分显著。据在马嵬公社界庄生产队调查,灌十立米水麦田的平均单株分蘖数,也较未泼灌的多零点四个到一个,次生根多一点三个。这是缺水地区抗旱的一个好办法,当然,小畦自流灌溉要比自流结合泼浇的质量更好。水量大,自流引水有条件的地区,仍以用自流小畦灌溉为宜。在采用自流结合泼浇的灌溉方法时,还需要注 Ditching combined with spill pouring Yangling County, Shaanxi Province, Yangling commune Xiajiagou production team, Mabu commune sector Zhuang District adopted “ditching combined with sprinkling pouring” is a good time saving water provincial methods. That is: In the wide-barking between the brooms, every four to five meters of gully water diversion irrigation, and then artificial long-handled scoop assisted pouring around, pouring ten meters per mu, 45 meters more than run-down irrigation to save water three or four times, Although this method of irrigation irrigation amount is not large, but the growth and development of wheat is still very significant effect. According to the investigation of the Zhuang community in Mantan commune, the average number of tillers per plant in irrigated rice fields was also 0.4% more than that in the unpolluted area, with a little more than three in the secondary roots. This is a good way to fight drought in water-scarce areas. Of course, small-sized gravity irrigation is better than gravity-flow irrigation. Large amount of water, gravity water diversion areas, still use small Irrigation is appropriate. In the use of gravity pouring irrigation method, but also need to note
