据调查,果园中的杂草,多数为单、双子叶一年生与多年生杂草混生,特别是深根杂草繁殖力强,根深且与果树争夺水分、养分剧烈,人工拔除也相当困难。为了研究果园化学除草的技术和效果,我们试用新型叶面处理剂,收到了见效快、除草干净彻底、经济效益高等效果,简报如下。 According to the survey, the weeds in the orchard are mostly single and the annual dicotyledon is mixed with perennial weeds. In particular, the deep-rooted weeds have strong fertility, deep roots and competition for water with fruit trees. The nutrients are intense and it is quite difficult to remove them manually. In order to study the technology and effect of orchard chemical weeding, we tried the new foliar treatment agent and received the quick results, thorough and clean weeding and high economic benefits. The briefing is as follows.
