Embodiment 1

[0018] The following embodiments take the method provided by the present invention in the construction of a certain urban forest, and through three years of follow-up observation, the weeding effect of weeds is compared as an example to illustrate the weeding method of the present invention for urban forests.

[0019] A kind of weeding that the present invention is used for urban forest, described method comprises the steps:

[0020] (1) loosen the soil, during the two seasons of summer and autumn every month, manually loosen the soil in the range of 5-10cm around each tree, the depth of loosening the soil is 5-10cm, and form a circular tree hole around the tree; In this embodiment, preferably, the diameter of the tree hole is 50-100 cm. Before loosening the soil, it is necessary to sprinkle water around the tree; when loosening the soil, ensure that there are no soil clods, and the root system of the tree will not be affected and the bark will not be damaged.

[0021] (2) sp...

Embodiment 2

[0033] Randomly select 36 trees to carry out parallel test in addition, in the step (1) of above-mentioned embodiment 1, the thickness of 0.5cm is established with the straw ash of 5:6 and slaked lime at the bottom of described loose soil, other conditions are all with implementation Example 1 is the same. The results in Table 2 below were obtained.

[0034] Table 2: Comparison of herbicidal effects on weeds

[0035] number of years Proportion of weeds in lawn (%) Proportion of weeds near the tree hole (%) Let the weeds grow 49.7 78.3 The first year of the invention 0.21 0.42 The second year of the invention 0.20 0.63

[0036] According to the results in Table 2, it is obvious that the weed growth inhibition effect of the method of the present invention is good by spreading 0.5 cm of straw ash and slaked lime mixture at the bottom of the loose soil.

[0037] The weeding method used in urban forests provided by the present invention great...

Abstract

The invention provides a method for weeding an urban forest. The method comprises a step (1) of loosening soil, manually loosening oil within a range of 5-10 cm around each tree each month in summer and autumn each year, causing the soil loosening depth to be 5-10 cm, and stacking the peripheries of trees into round tree pits; a step (2) of spraying pesticides, and spraying chlortoluron wettable powder with a ratio of 15% into loosened soil, wherein 10-20 g of chlortoluron wettable powder is sprayed around the tree pits of each tree; a step (3) of performing weeding, manually performing intertillage and weeding around the trees, applying 5-10 g of oxyfluorfen and pndimethalin around the tree pits of the trees, wherein the compound mass ratio of oxyfluorfen and pndimethalin is 1:10 to 2:1; a step (4) of performing trimming, flattening the peripheries of the tree pits after the weeding, clearing weeds around the tree pits, and making the boundary between a lawn around the trees and the edgesof the tree pits clear. According to the method for weeding the urban forest, alternate growth of the weeds around the trees and the lawn is controlled, and an urban greening beautifying effect is improved.

Description

technical field [0001] The invention relates to the technical field of urban greening construction, in particular to a method for weeding urban forests. Background technique [0002] As a special type of forest, urban forest belongs to the category of forest and is different from natural forest. It has its own uniqueness. Generally speaking, forests are called "the lungs of cities". Building forests in cities is like adding breathing functions to cities. Environmental climate and water conservation play an important role. However, in the process of urban forest construction, it is necessary to consider the current situation of single urban forest structure and too large open space. In the existing situation, due to the single structure of the urban forest, lawns are often planted among the urban forest trees. But there is no effective maintenance and repair method for the lawn in the urban forest at present, which makes the forest overgrown with weeds, and robs the nutrie...
