[0005] Chinese patent application 201611214132.X discloses a method of using Eguancao "Runcao 2" to suppress orchards, but because the plants are slender and prone to lodging, it is not conducive to agricultural operations in the later stage, and this method is only for the middle and lower reaches of the Yangtze River, so it is relatively difficult to promote. limitations
Chinese patent application 201510531452.7 discloses a method of using snakeberry to control weeds in orchards, but it is not known whether this method can also be applied to the control of weeds in tropical orchards
Other leguminous plants such as alfalfa, clover cloverleaf and gramineous plants such as paspalum broadleaf, bahia grass, foxtail, etc. are also widely used, but in actual production practice, such plants are common pastures. High water demand and high maintenance costs

Embodiment 1

[0024] Investigated the effect of Jiangteng on the germination of crop seeds. See Table 1.

[0025] Table 1. Effects of different concentrations of the extracts of the vine on the germination of several crop seeds

[0026]

[0027]

[0028] It can be seen from Table 1 that different concentrations of the extracts of G. edulis had no significant effect on the germination rate of wheat, radish and rape seeds. It can be seen that the vine has no allelopathic effect, can be used for planting in the orchard ecosystem, and will not produce allelopathic effects on fruit trees and other crops.

Embodiment 2

[0030] This embodiment provides a method for controlling weeds by utilizing the vine ecology.

[0031] Location 1: Hainan Lychee Garden

[0032] Specific steps are as follows:

[0033] From low March to early April, collect vines in the wild, and cut the stems of vines into segments with a length of 5-10 cm, and make each stem segment have 1-2 nodes.

[0034] The weeds in the orchard were manually cleared, and then the vines were planted.

[0035] The planting method is cutting, the cutting depth is 1-3cm, the distance between cuttings is 10-20cm, to ensure that the nodes of each stem segment are in contact with the soil, and after the cutting is completed, it is properly suppressed.

[0036] Water once and thoroughly, and there is no need to water the vines in the future, just water the fruit trees normally. There is no need to mow the vines, and there is no need for pest control.

[0037] Prevention and control effect inspection:

[0038] 1. From the perspective of grow...

Embodiment 3

[0047] Location 2: Guangxi Kiwi Fruit Garden

[0048] Specific prevention steps:

[0049] From low March to early April, collect vines in the wild, and cut the stems of vines into segments with a length of 5-10 cm, and make each stem segment have 1-2 nodes.

[0050] First, weeds in the orchard are manually cleared, and then vines are planted.

[0051] The planting method is cutting, the cutting depth is 1-3cm, the distance between cuttings is 10-20cm, to ensure that the nodes of each stem segment are in contact with the soil, and after the cutting is completed, it is properly suppressed.

[0052] Water once and thoroughly, and there is no need to water the vines in the future, just water the fruit trees normally. There is no need to mow the vines, and there is no need for pest control.

[0053] Prevention and control effect inspection:

[0054] 1. From the perspective of growth:

[0055] After the cuttings of the cross-river vine, roots can take root in 2 days, and the base...

Abstract

The invention relates to a method of utilizing verbenaceae lippie to prevent and control weed in an orchard. The method includes: planting verbenaceae lippie in the orchard by means of cutting or broadcast sowing. The method is quite good in prevention and control effect, can make temperature difference change of soil small, is conducive to root system growth of fruiters and absorption of nutrientand has effect of reducing water and soil loss; verbenaceae lippie is adopted to avoid risk caused by introduction of alien species, and verbenaceae lippie has the advantages of low requirements on soil and high resistance to pest and disease, thereby having wider suitability.

Description

technical field [0001] The invention relates to a method for controlling weeds in orchards by using vines, belonging to the technical field of ecological control. Background technique [0002] In my country, there are many kinds of weeds in orchards, and there are more than 700 kinds of weeds that harm orchards, of which 38 are vicious weeds. Weeds in orchards will consume soil nutrients, breed diseases and insect pests, deteriorate the ecological environment of orchards, directly or indirectly harm the growth and development of fruit trees, and affect the field operations of orchards; In severe cases, the output will be reduced by 30% to 40%. [0003] Weed control in orchards has always been a major problem in agricultural production. Manual weeding is not only difficult to completely remove weeds, but also time-consuming and labor-intensive. Although chemical herbicides can effectively control weed damage, long-term use of chemical herbicides, especially long-term use of...
