育苗工作,特别是采用撒播方式培育针叶树种(即杉松苗木)的除草问题,多年来一直停滞在以人工拔草的落后现状,致使苗木生产成本高,投资大,损苗多。以人工拔草消灭草害,是育苗工作中劳力、经费投资比例最大的项目。据统计从四月份掀草开始,到八月底止,五个月时间,每亩需除草15-18次之多,每次用工量达12个工(妇女儿童)平均日工资0.45元,每次除草工资达5.4元,全年每亩除草用工达180-216个,工资达81元左右,全场今年共培育杉松苗35亩,总共需要6300个劳动工日,工
Nursery work, especially the cultivation of softwood species of conifers (ie, fir-tree seedlings) by means of sowing, has for many years been stagnating in the backward state of artificial weeding, resulting in high cost of seedlings production, large investment and loss of seedlings. Artificial weeding to eliminate grass damage is the labor force in breeding work, the largest proportion of funds investment projects. According to statistics, from the start of the grass-raising in April, the total amount of weeding per acre is 15-18 times as much as five months by the end of August, with an average daily wage of 0.45 yuan for every 12 workers (women and children) Weeding wages of 5.4 yuan, the annual weeding of up to 180-216 acres of labor, wages of about 81 yuan, the audience this year a total of 35 acres of spruce pine seedlings, a total of 6,300 labor day, workers
