近几年来,国内一些地区进行了耕作改制的探讨,试行了少耕、免耕法,取得了初步成效.但少耕、免耕法不是“刀耕火种”的重复,而是多学科的综合利用,难度较大.不解决杂草、机具配套和破残茬等问题,大面积推广少耕、免耕法就有一定困难.传统的翻耕法成本高、能源浪费大,对土壤结构破坏力强,要大幅度提高劳动生产率、商品率及财物利用率,会受到一定限制.目前新疆国营农场农业机械化程度不算太低,但生产水平不高,有些农场财务仍有亏
In recent years, some areas in China have carried out discussions on farming system reform and tried out less tillage and no-tillage methods, and achieved initial success. However, tillage and no-tillage are not repetitions of “slash-and-burn” but are multidisciplinary comprehensive utilization. Difficult to solve the problem of not solving weeds, supporting machinery and broken stubble, spreading less tillage on a large scale, there is some difficulty in no-tillage method.The traditional tillage method has the advantages of high cost, large energy waste and strong destructive effect on soil structure , To substantially increase labor productivity, commodity rate and utilization of property, will be subject to certain restrictions.Currently state-owned farms in Xinjiang is not too low degree of mechanization, but the production level is not high, some farms are still financial deficit
