荒漠草原地带降水稀少,可利用水分有限。因此,必须通过树木整个生长期间的林地管理和幼林抚育技术,长期积蓄和有效使用林地水分,才能维持人工林的稳定生长。在造林后的最初3年内,由于树体矮小,因此,行间可用除草机,株间则用大锄头施行松土除草作业.当树高超过2米以后,用机引雁形铧在行间中耕除草,耕深12～15厘米。待表土干燥后,用机引缺口圆盘耙将土块破碎,再用圆杆 Desert grasslands scarce precipitation, water availability is limited. Therefore, the stable growth of plantations must be maintained through long-term savings and effective use of woodland water through woodland management and young plantation technology throughout the growing season of trees. In the first three years after afforestation, due to the short tree, therefore, weeding machine can be used between the lines, and plants are used for large-scale hoe weeding operation.When the tree height of more than 2 meters, Cultivation weeding, deep plowing 12 to 15 cm. To be topsoil dry, with the machine notched disc harrow will break the block, and then round rod
