随着园林绿化工作的快速发展，园林苗圃清除杂草的工作量也越来越繁重，人工除草已远不能适应，除草剂的大量应用已提到议事日程。我们的试验表明，对３年生丹东桧柏苗地喷施７５％金锄可溶性粉剂，每公顷用量达０８４ｋｇ时，除草效果可达９３％；喷施草灌净、森草净效果可达８９％以上。以上药剂对丹东桧柏苗木无任何药害，且高、径生长量均略高于对照。最佳施药期为苗木高约１０ｃｍ时。
With the rapid development of landscape gardening, the workload of clearing weeds in garden nurseries has become more and more heavy. Artificial weeding has become far from adequate. A large number of applications of herbicides have been put on the agenda. Our experiments showed that spraying 75% gold hoe soluble powder on 3-year-old Daphnia cynthia seedlings with the dosage of 084 kg per hectare could achieve a herbicidal effect of 93% More than 89%. Above Dandong juniper cypress seedlings without any phytotoxicity, and high, diameter growth were slightly higher than the control. The best application period for seedlings about 10cm high.
