我省甘蔗种植面积90万亩,每年人工除草要花费相当大的劳力。为了解决劳力紧张和降低成本,我们通过在本所农场甘蔗园使用除草剂,效果十分明显。试验结果表明,一般人工除草每人每天只能完成0.4亩,而化学除草即可完成4亩,工效提高10倍。人工除草每亩一次需10元,而化学除草仅需3～4元。 Sugar cane cultivation area of ​​90 million mu, annual artificial weeding to spend considerable labor. In order to solve the labor shortage and reduce the cost, we use the herbicides in the sugar cane garden of our farm, the effect is very obvious. Test results show that the general artificial weeding only 0.4 mu per person per day, while the chemical weeding can be completed 4 acres, 10 times the work efficiency. Artificial weeding once per acre required 10 yuan, and chemical weeding only 3 to 4 yuan.
