Method for preventing exotic weeds from invading by cultivating ramie

Abstract

A method for preventing exotic weeds from invading by cultivating ramie is provided, comprising the steps of (1) forming plantation grooves on the selected sample land; (2), preparing fertilizer formed by weeds, soil and so on; (3), preparing compost; (4), applying the compost and the fertilizer to the plantation grooves; (5), planting ramie and exotic weeds in the plantation grooves in an interplanting manner; (6), collecting ramie leaves and ramie stalks when peeling ramie to cover the plantation grooves; (7), baking the fertilizer during autumn and winter; spraying the fertilizer on the plantation grooves, using straws to cover the plantation grooves so as to prevent the ramie hill from being frozen and inhibit the weed seedlings from growing. The ramie is perennial deep-root herbage, so that the ramie has strong adaptability and fast growth speed, forms thick vegetation at short time, and can inhibit Ageratum and Solidago Canadensis from growing competitively and inhibit those exotic weeds from invading. The method has the advantages that the method is convenient to take materials, has simple technology, is easy to operate, has short reconstruction vegetation time, good effectfor preventing exotic weeds and has no risk and the like.

Description

technical field [0001] The invention relates to the field of plants, in particular to a method for cultivating ramie to prevent and control the invasion of foreign weeds, red thistle and solidago canadensis. Background technique [0002] Alien plant invasion has become a global ecological problem. Red Thistle ( Ageratum conyzoides ) and Solidago ( Solidago canadensis ) are two kinds of alien malignant weeds with great influence. Red thistle originated in South America, and goldenrod is native to North America, both of which occur in large quantities in my country and cause serious damage. These two exotic weeds can produce and release a variety of allelochemicals, and have the effect of heterogeneity; they breed and spread in large numbers in farmlands, orchards, etc., affecting the growth and development of crops, resulting in reduced yields; due to their wide ecological adaptability, inhibiting The growth of native plants and other plants often forms single-optimal o...

AI Technical Summary

Problems solved by technology

(2) Using chemical control methods such as herbicides, such as using glyphosate to control solidago canadensis, this method can be used in large areas, but the large amount of herbicides will pollute the environment and may cause harm to the human body

(3) Biological control methods, such as using dodder (Cuscuta campestris) to parasitize Mikania micrantha (Mikania micrantha), biological control methods are suitable for large areas, but there are biological control methods Potential risks due to new changes in agents after their introduction

Artificial control methods and chemical control methods are only effective for a short period of time
