我区共有水田面积四万三千四百亩,而冷浸田有一万一千七百余亩,占全部水田的27%,因此冷浸田的改造,对于增加我区的粮食产量有着较大的意义。现就本区改造冷浸田的一些具体实例作粗浅的介绍。湾里区农科所地处湾里过水垅,52亩水田是由红壤土发育而成的冷浸性水稻田,其中15亩是深脚烂泥田。52亩水田原来均为亩产200～300斤的低产田。他们采取了以下几个主要措施: 1.开沟排水,围泉排水,根除水害。两边开挖了排洪沟,排除山洪。垅中用麻石干砌了一条宽0.4米,深0.4米,总长350米的暗沟(暗沟沟通了冷泉眼),田边开两条排灌
My area has a total of 43,400 acres of paddy fields, and cold paddy fields have more than 11,700 acres, accounting for 27% of paddy fields, so the transformation of cold paddy field, to increase the grain output in our region has more Big meaning Now on the reform of cold-immersed fields in some specific examples for a superficial introduction. Wanli District Agricultural Institute is located in the Bay over the water 垅, 52 acres of paddy field is developed from the red loamy cold-paddy rice fields, of which 15 acres are deep muddy fields. The original 52-mu paddy fields are all low-yield fields with 200-300 kg mu per mu. They took the following major measures: 1. Ditching drainage, Wai spring drainage, water eradication. Drainage ditch excavated on both sides, excluding torrents.垅 in the use of dry stone masonry a width of 0.4 meters, 0.4 meters deep, total length of 350 meters under the ditch (gutter communicate cold spring eyes), Tanabe open two irrigation
