五节芒生长发育规律及森泰化除试验研究

Study on the Growth and Development Rhythm of Miscanthus floridulus and Its Chemical Weeding Experiments with Herbicide Hexazinone

本文通过野生五节芒生长情况和五节芒人工培育的调查研究,分析其生长发育规律;在人工中幼林地和抛荒农耕旱地上利用5%森泰除草剂对五节芒进行化学除草试验,总结了用该除草剂防除1至多年生五节芒获得最大效果的最适宜施药季节和用药剂量,为林地化学除芒提供了技术支持。

In this paper a survey study was made on the growth and artificial cultivation of Miscanthus floridulus and its growth and development rhythm was summarized. Its chemical weeding experiments were carried out in young and mid-aged plantations with 5% herbicide Hexazinone. The most suitable application season and dosage was summarized with the optimum chemical weeding effects for 1 to 5-year-old Miscanthus floridulus plants,and the study could provide technical support for chemical weeding in forestland.
