摘要
在大果沙棘一年生扦插苗移植生产工作中,由于采用了大垄双行密植栽培,给人工除草工作带来很大困难,用人工除草不但用工量过大,投资大,而且要损失很多苗木,因此,选择适合于沙棘嫩枝扦插苗除草方式方法,是我们育苗科技工作者急于解决的问题之一。我们在生产实践中经过反复试验证明,应用除草剂是大果沙棘嫩枝扦插苗除草的最佳方法之一。我们根据一些除草剂的理化性质、毒性、作用机制、产品特点,选择了几种除草剂,进行田间试验,结果表明果尔除草效果好,可以推广使用。
Since the field application the double line and broad ridge in transplantation, weed control becomes a hard job in post-transplantation of one-year-old green cuttings. The weeding by hand was time consuming, heavy cost and damage to young seedlings. It is highly in need to find a cost effective way to control weed. The field experiences showed that herbicide was a practical option. The physical and chemical properties, toxicity and function mechanisms, etc. were considered in herbicides selection. Several kinds of herbicides were experimented in the field. The results showed that the herbicide namely Oxyfluorfen had a satisfied effect.
