化学灭草是一种花工少,经济和成效快的控制杂草的新途径,应用于苗圃有良好效果。为了探索杉木幼林中化学除草的效果,我们于1975年和1976年在杉木幼林中进行了化学除草杀灌试验。主要目的是研究除草剂的筛选、用量、施用方法和施药季节。供试杉木幼林林令分别为1年和2年生。地形为丘陵,土壤大多为第四纪红壤。林地植物种类:草本植物有扛板归、蓼类、一年蓬、苍耳、马唐、鬼针草、白茅、旱稗、铁芒箕、菅草、芭茅等;灌木有(?)木、茅栗、山槐、白栎、茅莓、金樱子、算盘子、大青等。供试除草剂有草枯醚、利谷隆、除草醚、五氯酚钠、扑草净、2.4-D丁酯、除草佳、敌稗等8种药剂。一、试验内容和方法试验内容包括:1.除草剂的筛选。2.除草剂的用量和施用方法。3.除草剂施用季节及对
Chemical weed control is a new way to control weeds with less pollination, economy and quick effect. It has good effect in nursery. In order to explore the effectiveness of chemical herbicides in young Chinese fir plantations, we conducted chemical weeding tests in young Chinese fir plantations in 1975 and 1976. The main purpose is to study herbicide screening, dosage, application method and application season. For the test young pine forest orders were 1 year and 2 years. Terrain for the hills, most of the soil for the Quaternary red soil. Woodland Plant species: Herbaceous plants are Pleurotus ostreatus, Polygonum, year-old Peng, Xanthium crab, Crabgrass, Bidens pilchard, white grass, Adenophora, ferns Kei, Na grass, , Mao Li, Locust tree, white oak, Mao Rui, Rosa laevigata, abacus, Daqing and so on. The tested herbicides were clomazone, liragluone, weeding ether, sodium pentachlorophenol, prometryn, 2.4-D butyl, weeding good, propanil and other eight kinds of agents. First, the test content and methods The test includes: 1. Herb screening. 2. The amount of herbicides and application methods. 3. Herbicide application season and right
