为了使广大果农更好地、有效地掌握化学除草技术,近年来我们进行了较大面积的试验,现将一些经验介绍如下: 一、慎重选药根据果树种类,树龄和杂草种类慎重选药: 1.苹果树、梨树宜用草甘膦、阿特拉津、西玛津、扑草净等除草剂。如果杀除茅草、芦苇等多年生禾草,可优先选用草甘膦。草甘膦是一种灭生性触杀类除草剂,药味清淡,除草效果优于其它除草剂。一般用药2—3次可基本上根除杂草。如果以杀灭一年生马唐等杂草为主,选用阿特拉津、西玛津、扑草净等为好,它们药效期长、杀草谱广,进行土壤处理几乎可以控制
In order to enable the majority of fruit farmer to better and effectively grasp the chemical weeding technology, in recent years we conducted a large area of the experiment, we now introduce some of the experiences are as follows: First, careful selection of drugs according to the type of fruit trees, age and weed species careful selection of drugs : 1. Apple trees, pear should use glyphosate, atrazine, simazine, prometryn and other herbicides. If you kill the grass, reed and other perennial grasses, glyphosate may be preferred. Glyphosate is a biocidal contact herbicide with light and herbicidal effects superior to other herbicides. 2-3 times the general use of drugs can basically eradicate weeds. If the annual crabs and other weeds to kill the main selection of the selection of atrazine, simazine, prometryne and so on, they have a long duration, broad spectrum to kill grass, soil treatment can be controlled almost
