Problems solved by technology

The forest herbicide Wilbur or 5% hexazinone and 15% glyphosate ammonium salt are used to spray the Admiralty vine, although the control effect is good, but the dose required is large, and the residual time in the soil can be as long as 8-10 days. months, affecting the ecological environment
[0004] At present, there are not many types of pesticides suitable for the control of local harmful vines, which have the disadvantages of large amount of use, large phytotoxicity to other trees and shrubs, and long residual period in the soil.

Abstract

The invention provides a rural-harmful-liana integrated control method. The rural-harmful-liana integrated control method includes the steps of chemical controlling, wherein a chemical prepared from acomposition of picloram, 2,4-dichlorophenoxyacetic acid, bentazone and sulfometuron-methyl is sprayed onto vines and stems of rural harmful liana according to the applying quantity of 3,000 ml hm<-2>to 5,000 ml hm<-2>, and the leaf withered rate of the rural harmful liana is up to 50% or above; clearing, wherein the rural harmful liana obtained after chemical controlling is cleared to remove thevines and the stems of the rural harmful liana on the ground; ecological controlling, wherein mixed planting of quick-growing species of trees is conducted in a cleared region according to the plantspacing and the line spacing of 1.0 m to 2.0 m*1.5 m to 3.0 m, the trees are cultured for 1 year to 2 years, and growth and spreading of the rural harmful liana are gradually controlled. According tothe rural-harmful-liana integrated control method, the dose of the applied chemical is low, soil pollution is small, the rural harmful liana causing large-area harm can be efficiently killed, a laterecological system of a killing region can be maintained to be stable, and the ecological safety performance is high.

Description

technical field [0001] The invention belongs to the technical field of harmful plant prevention and control, and in particular relates to a method for comprehensive prevention and control of native harmful vines. Background technique [0002] Lianas are an important structural component of vegetation communities. They are a type of plants whose stems are soft and cannot stand upright freely. They need to rely on the stem itself or other objects to climb, twine or crawl. Most vines are conducive to enriching the structure and function of the forest ecosystem, maintaining the stability and positive evolution of the forest ecosystem, but there are also some vines that multiply, spread, entangle, cover, strangle, and crowd out other plants, seriously destroying the original forest The plant community structure causes forest degradation, functional decline, and biodiversity reduction. Such vines are called harmful vines. Harmful vines can reduce tree growth rate, cause tree with...
