一、什么叫做细流沟灌 新疆是灌溉农业区,采用先进的灌水方法,对于实现农业稳产高产有着重大的意义。目前,旱田中耕作物已较多地采用普通的沟灌,密植作物不少已采用畦灌。但落后的大水漫灌灌水方法,一些地区仍在采用。 普通的沟灌、畦灌,比起大水漫灌,质量好,省水,也减少了地下水的补给,能有效地提高作物产量。但在地面坡降较大地区,特别是板结土,则易严重拉沟,大量流失水土,冲坏禾苗,并造成低处受涝、高处受旱。更因是跑马水,水不能充分下渗,土壤墒度不足,不能抗旱保收。不少旧灌区,特别在南疆,坡度 First, what is the trickle ditch Xinjiang is an irrigated agricultural area, the use of advanced irrigation methods for the realization of a stable and high yield of agriculture is of great significance. At present, dryland crop cultivation has been more commonly used furrow irrigation, densely planted crops have adopted a lot of irrigation. But behind the flood irrigation method, still using some areas. Ordinary furrow irrigation, irrigation, compared to flood irrigation, good quality, water, but also to reduce the supply of groundwater, can effectively improve crop yields. However, in the area with large slope, especially the plate knot soil, it is easy to pull the ditch seriously, draining soil and water in large quantities and redressing the seedlings and causing low waterlogging and drought. More due to horse water, water can not be fully infiltration, lack of soil moisture, can not be drought-resistant income. Many old irrigation areas, especially in southern Xinjiang, slope
