把坡地一次修成水平梯田,不仅能够徹底控制水土流失,而且当年产量可以一步登天。山西省离山县柳林乡今年春季一次修成水平梯田12,000多亩,预估亩产可达到800斤至1,000斤,比原产量提高8至10倍,其中棉花試驗田亩产籽棉可达1,000斤,玉米試驗田亩产可达1,500斤。临县安業乡在新修水平梯田上种的糜子,杆高1.7公尺,亩产可达1,000斤以上,一些在过去一直帶着“低产”帽子的地方,修了水平梯田以后,一躍而为高产区。但是,在一次修成水平梯田的操作方法和培埂、填壕等一系列的技术上,目前尚缺乏系統的完整的經驗。不少地区修成一亩水平梯田总得花費30到40个
Once the slopes have been repaired to horizontal terraces, not only soil and water loss can be completely controlled, but the output of that year can be ascend one by one. This year, Liulin Township, Lianshan County, Shanxi Province, repaired more than 12,000 mu of horizontal terraced fields this spring. It is estimated that the yield per mu will reach 800 to 1,000 kilos, an increase of 8 to 10 times than that of the original output. Cotton yield may reach 1,000 kg per mu, Ma test field yield up to 1,500 pounds. An County, Linxian County in the newly built level terraces on the barley, pole height of 1.7 meters, up to 1,000 pounds per mu or more, some in the past has been with a “low yield” hat, repaired the terraced fields, jumped to High yield area. However, there is still no systematic and complete experience in a series of technologies such as the operation method of cultivating horizontal terraces and the cultivation and filling of ditches. In many areas, it takes 30 to 40 to cultivate terraces with an acre of land
