一、银北种稻的历史回顾银北在六十年代以前已有第三、四、五三条排水干沟,但是支、斗、农沟没有配套,在这样的条件下大面积种稻,严重地破坏了水盐平衡,引起地下水位上升,造成土壤返盐,这是应当牢记的教训。当时的种稻是一哄而起,没有区划和规划,也没有注意稻旱之间的隔离条件,高斗高地也盲目种稻。强调了种稻比种旱当年产量高,但由于土壤盐化,以后几年的产量越来越低,造成了被动局面。
First, the history of silver north of paddy Review Silver North in the sixties before the third, fourth, five or three drainage ditches, but branch, bucket, ditch is not complete, under such conditions, large areas of rice, Seriously destroying the water-salt balance, causing the water table to rise and causing the soil to return salt, a lesson that should be kept in mind. At the time of planting rice is one after another, there is no zoning and planning, nor pay attention to the isolation conditions between rice drought, high bucket also blindly planted rice. It stressed that the yield of rice was higher than that of the year of drought, but due to the salinization of soil, the output in the next few years is getting lower and lower, resulting in a passive situation.
