2000年省厅农机局组织省内有关农机科研单位和生产企业,通过多次试验、改进,精心研制出了一种能在收完庄稼,在秸秆直立或粉碎的状态下,一次完成播种、施肥、覆土、镇压(有的还进行秸秆粉碎)等多项作业的免耕播种机。这种被称为“机械化保护性耕作技术”,由于不破坏硬质地表土层,并有秸秆覆盖地表,所以可以起刭防风固沙等作用。经藁城市农机局在马庄农场进行的21亩对比试验结果表明。 In 2000, the Provincial Department of Agriculture and Forestry Bureau organized agricultural scientific research units and manufacturing enterprises in the province. After many tests and improvements, it has carefully developed a plant that can finish planting and fertilizing once the crops are finished and the straw stands upright or crushed , Soil cover, suppression (and some also carry out straw crushing) and many other no-till planter. This is called “mechanized conservation tillage technology,” because it does not damage the hard surface soil, and straw covering the surface, it can play the role of wind and sand fixation. The results of a comparative study of 21 mu conducted by Zhuo Cheng Agricultural Bureau in Mazhuang Farm showed.
