幼林除草是提高造林成活率和促进幼林生长的重要措施之一。但是幼林需除草的时候,也是农忙季节,农林争劳力的矛盾很大,往往因此而推迟除草时间或完不成任务。化学除草剂在育苗上的使用,给我们提供了新的除草途径。但是由于目前化学除草剂多配成液剂使用,在大面积山地幼林中除草,仍受人力、物力、药械等条件的限制。为了解决这一问题,我们改变了除草剂剂型,进行了除草试验,获得了初步效果。现简介如下: 把可湿性粉剂与过筛的炉灰或柴灰,按1:500的比例配成粉剂。5月31日用喷粉器把
Weeding young plants is one of the important measures to improve the survival rate of afforestation and promote the growth of young forest. However, when weeding young grasslands is also a busy season, the contradictions between agriculture and forestry are so great that they often postpone the weeding time or fail to fulfill their tasks. The use of chemical herbicides on nurseries has given us new ways of weeding. However, due to the current use of chemical herbicides in liquid formulations, weeding in large areas of young mountain forests is still limited by the conditions of manpower, material resources, and medical equipment. In order to solve this problem, we changed the herbicide dosage form, conducted the weeding test and obtained the preliminary result.
