Method for suppressing weed growth of fruit tree land

Abstract

The invention discloses a method for suppressing weed growth of fruit tree land. The method comprises the following steps: applying fertilizer containing no weed seed to fertilization areas of rest-balk block surfaces of the fruit tree land after weeds in the fruit tree land are cleaned up, coating non-fertilization areas of the rest-balk block surfaces with black ground cloth, and coating rest-balk furrows and rest-balk furrow slopes of the fruit tree land with tarpaulins, wherein the fertilization areas refer to areas of which the distances with fruit tree roots are not more than 100cm. According to the method disclosed by the invention, the fertilizer containing no the weed seed covers the fruit tree roots to play a dual role in suppression of the weeds and fertilization; the black ground cloth covers the non-fertilization areas of the rest-balk block surfaces to improve soil water permeability and air permeability, lower soil temperature and protect soil environment of fruit tree growth so as to facilitate the growth of the fruit tree roots and reduction of the cost; the tarpaulins cover the rest-balk furrows and the rest-balk furrow slopes, so that full-area coverage of the fruit tree land is implemented to prevent the weeds in rest-balk block peripheries from growing to rest-balk block areas, meanwhile, robustness and durability of the tarpaulins are utilized to achieve the effect of sustained weeding for multiple years by a one-time operation so as to reduce the labor cost of weeding operation.

Description

technical field [0001] The invention relates to a method for inhibiting the growth of weeds, in particular to a method for inhibiting the growth of weeds in fruit trees. Background technique [0002] Most of the fruit trees are perennial trees. There are root systems of fruit trees in the cultivated land where fruit trees are planted, and the soil cannot be plowed. The commonly used weeding methods mainly include intertillage weeding and application of herbicides. During manual intertillage and weeding operations, the root system is easy to be damaged; in addition , the effective time of manual weeding operation is very short, and the labor efficiency is extremely low; after the application of herbicides, it will not only damage the root system, but also lead to a decline in soil quality, affecting the yield and quality of fruits. In the production practice of planting fruit trees, people continue to explore new weeding methods, one of which is mulching with plastic film. In...

Problems solved by technology

The Chinese patent application number 201010130907.1 discloses a method for mulching citrus orchard soil with straw. In this method, there is too little coverage with straw in the orchard, and it is impossible to control the weeds in the furrows of the fruit trees from spreading to the covered area. In addition, some fruit trees such as The plant height of blueberry trees is far less than that of citrus. Too thick coverage will affect the growth and yield of blueberries, and cannot meet the coverage thickness required by the patented technology, which will affect the weed suppression effect.

The Chinese patent with the application number 201310476335.6 discloses a method of ecological weeding. This method cannot remove all weed seeds, nor can it remove weeds propagated by rhizomes. Secondly, the time for this method to produce effects is very limited

The Chinese patent with the application number 201410511186.7 discloses an ecological weeding method for orchards in southern Jiangsu hilly areas. The main method is to plant annual green manure crops between fruit trees. This method is labor intensive and the weeding effect is not ideal. One-time planting and harvesting to process green manure, which saves cost and has unsatisfactory weeding effect

The Chinese patent with the application number 201410833156.8 discloses a special weeding mat for camellia oleifera and a weeding method. The method requires a lot of labor and the continuous weeding effect is not ideal. greatly damaged
