水稻是一种高产粮食作物,种植水稻对重盐碱地区来说,又是改良土壤的有效措施.塔里木河地区种植水稻面积逐年倍增,而在用以改良盐碱土地方面也取得了显著的效果.但与此相反的是,由于种植水稻而使地下水位上升,给机耕工作带来了许多困难.的确,在水稻茬地上进行机械耕作,我们走了不知多少的弯路,才摸索了一些经验.现简介如下,以供大家参考. Rice is a high-yielding grain crop, and planting rice is an effective measure to improve the soil in heavy salinization areas. The area of ​​rice planted in the Tarim River region has doubled year by year, and remarkable results have also been achieved in improving saline-alkali soil. Contrary to this, the increase of groundwater table due to the cultivation of paddy has brought many difficulties to the cultivation work. Indeed, we have groped for some experience after carrying out mechanical farming on the rice stubble. Brief introduction is as follows, for your reference.
