Problems solved by technology

[0005] The purpose of the present invention is to provide a method for the management and control of weeds in orchards in South China, to solve the problem that during the production of pollution-free fruit in South China, many pesticides are used for the control of weeds in orchards, and long-term and large-scale use of pesticides is likely to cause adverse effects on the growth of fruit trees and the ecological environment of orchards. problem of influence

Embodiment 1

[0039] A method for the management and control of weeds in litchi orchards in South China Plain, comprising the following steps:

[0040] (1) Collection of seeds of broadleaf floribunda

[0041] Select the wasteland where broad-leaved floribunda grows in a large area, harvest a large number of broad-leaved floribunda at the maturity of the broad-leaved floribunda seeds in December, put them in sacks and transport them to the open air for about one week, and collect them from the stalks After peeling and removing impurities, the fallen seeds should be stored in a dry and cool place for later use.

[0042] (2) Sowing method of broad-leaved floribunda

[0043] Broadleaf floribunda can be sown throughout the year. In this example, the best sowing time is from February to April, and from February to April, when there is more rain and the temperature gradually warms up, it can meet the moisture and 25°C required for the germination of broadleaf seeds. Above the temperature. 15-30 days bef...

Embodiment 2

[0047] The difference between this example and Example 1 is that the orchard is a litchi orchard in the hills of South China, and glufosinate-ammonium is sprayed to remove weeds in the orchard. The spraying amount of glufosinate-ammonium is calculated as 200g / L glufosinate-ammonium water. The dosage is 100ml~120ml / 667m 2 , Mixed with water 30-40kg; the spread of broad-leaved floribunda seeds is 400g / 667m 2 . In the second year of cultivation, because the coverage of broad-leaved floribunda is less than 90%, use 100ml~120ml / 667m 2 The 200g / L glufosinate-ammonium aqueous solution was sprayed again. Such as Figure 8-10 As shown, in the third year of cultivation, high-density grasses are formed, which can continuously inhibit the growth of other malignant weeds. The inhibition rate of other weeds in broad-leaved floribunda reaches more than 90%, and it has a continuous weed control effect throughout the year. . After using broad-leaved floribunda to control weeds, soil erosion i...

Abstract

The invention provides a method for managing and controlling weeds of an orchard in South China. The method comprises the following steps: (1) spermacoce latifolia seeds are uniformly spread in the orchard; after the weather becomes warm and the seeds are germinated, a spermacoce latifolia population is established; (2) after the spermacoce latifolia population is established, spermacoce latifolianormally flowers and bears fruits; after the spermacoce latifolia is withered, seeds falling into oil are germinated again in the next year to form a dominant population; a process goes full circle to realize a continuous inhibition effect on the growth of the weeds of the orchard. According to the method for managing and controlling the weeds of the orchard in South China, provided by the invention, sod cultivation is carried out by utilizing the spermacoce latifolia which is shallow in root system distribution and strong in invading capability and can easily form a high-density grass cluster; the aim of inhibiting the weeds is realized through competing for ecological niches; the problem of preventing and controlling the weeds of the orchard in a production process of pollution-free fruits under different site conditions in South China is solved.

Description

Technical field [0001] The invention relates to a method for the management and control of weeds in South China orchards. Background technique [0002] Weed damage in orchards is a prominent problem in fruit tree production. Orchard weeds compete with fruit trees for nutrients and water, which directly affect the yield and quality of fruit trees. At the same time, it is also one of the intermediaries and main hosts of many fruit tree diseases and insect pests. [0003] At present, the methods for controlling weeds in orchards include: chemical weeding, artificial weeding, and mechanical weeding, of which chemical weeding and artificial weeding are the most commonly used methods. Chemical weeding is weeding by spraying chemical herbicides. It has the characteristics of low cost, high efficiency and long lasting period. One person can remove more than 10 acres a day. However, due to the certain toxicity of herbicides, long-term and large-scale use of herbicides It is easy to have a...
