Embodiment 1

[0035] The test site is in Shuangding Town, Nanning City, Guangxi. The selected orchard is a young citrus orchard with a tree age of 1 year. The slope farmland has a slope of 21 and the soil is red soil. Organic matter 12.1g·kg -1 , total nitrogen (N) 1.2g·kg -1 , total phosphorus (P) 0.6g·kg -1 , total potassium (K) 4.5g·kg -1 . The planting mode is the pattern of 3 rows of sweet clover + 2 rows of cat beans between the rows of citrus and 3 rows of sweet clover + sweet clover between the rows of citrus sowing sweet potatoes

[0036] Specific steps are as follows:

[0037] (1) Green manure sowing

[0038] (1) Sowing of sweet-scented clover: remove weeds in the orchard before sowing; sow on March 26, 2016, using hole sowing, the sowing position is more than 100cm away from the trunk of the fruit tree, the sowing row spacing is 30cm, the plant spacing is 20cm, the sowing depth is 2-4cm, and each hole is 2 -3 grains, covered with soil after sowing; soak the seeds with 95% c...

Embodiment 2

[0049] In a 2-year-old orchard in Wuming District, Nanning City, Guangxi, an experiment was carried out to improve the ecological environment of the orchard by mixing sweet-scented clover and cat bean. The planting mode was 2 rows of sweet-scented clover + 1 row of cat bean between rows of citrus, slope farmland, and a slope of 19, The soil is red soil, and the basic physical and chemical properties of the soil between the rows of the citrus orchard were measured before the test, pH6.59, organic matter 16.43g kg -1 , total nitrogen (N) 1.38g·kg -1 , total phosphorus (P) 0.64g·kg -1 , total potassium (K) 4.61g.

[0050]Including the following steps:

[0051] (1) Green manure sowing

[0052] (1) Sowing of sweet-scented clover: remove weeds in the orchard before sowing; sow on March 25, 2016, using hole sowing, the sowing position is more than 100cm away from the trunk of the fruit tree, the sowing row spacing is 30cm, the plant spacing is 20cm, the sowing depth is 2-4cm, and ...

Embodiment 3

[0060] Experiments were carried out in the 1-year-old orchard of Shuangding Town, Nanning City, Guangxi to improve the ecological environment of the orchard by mixing sweet-scented clover and sweet potato.

[0061] Including the following steps:

[0062] (1) Green manure sowing

[0063] (1) Sowing of sweet-scented osmanthus: remove weeds in the orchard before sowing; sow on March 26, 2016, soak sweet-scented osmanthus in warm water at 80°C for 3 minutes before sowing. Use hole sowing, the sowing position is more than 100cm away from the trunk of the fruit tree, the sowing row spacing is 30cm, the plant spacing is 20cm, the sowing depth is 2-4cm, 3-4 grains per hole, and the soil is covered after sowing;

[0064] (2) Sowing of sweet potato: On October 26, 2016, strip sweet sweet potato was sown between the rows of sweet-scented osmanthus, with a seeding rate of 2-3 kg, and covered with soil after sowing;

[0065] (3) after sweet-scented clover and Chinese sweet potato sowing,...

Abstract

The invention belongs to the technical field of fruit tree cultivation and management, and particularly provides a method for improving the ecological environment by intercropping sweet clover with the multiple cropping combination of velvet bean and Chinese trumpet creeper in an orchard. The method comprises the steps of sowing with green manure, nursing and management, mowing and utilization andthe like. By intercropping the perennial upright green manure crop sweet clover with the multiple cropping combination of the summer green manure velvet bean and the winter green manure Chinese trumpet creeper in the orchard, the velvet bean, the Chinese trumpet creeper and other enwinding type green manure plants are guided in climbing on the sweet clover, prevented from climbing on vines and being wound on fruit trees and then prevented from affecting the growth of the fruit trees and fruits; through regular mowing, the surface of soil is covered with fresh grasses, and the land surface temperature is adjusted; the green manure and fresh grass production is increased, the content of organic matter in the orchard soil is increased, soil and water are preserved, weeds are inhibited, so that the application amount of chemical fertilizers is reduced, the ecological environment of the orchard is improved, the quality of the fruits is improved, and the market competitiveness is improved.

Description

technical field [0001] The invention belongs to the technical field of fruit tree cultivation and management, and specifically provides a method for improving the ecological environment by combining sweet-scented clover and cat bean-sweet seedlings in an orchard. Background technique [0002] With the further development of the agricultural economy, many fruit growers use a large amount of chemical fertilizers and herbicides in order to increase production and income in the short term, which reduces soil fertility and destroys the ecological environment of orchards, directly or indirectly affecting fruit quality. In recent years, some people try to improve the soil environment by mixing green manure in orchards. At the same time, green manure can also play a role in suppressing weeds and maintaining water and soil. However, the growth ability of green manure is generally relatively strong, and it is easy to climb and entangle fruit trees, affecting the normal growth of fruit...
