Problems solved by technology

At present, fruit growers blindly apply a large amount of chemical fertilizers to pursue high yields, and spray herbicides to suppress weeds, resulting in the decline of soil fertility in citrus orchards and the destruction of the ecological environment, directly or indirectly affecting the quality of fruit
In recent years, some people have interplanted green manure crops such as Labrador in citrus orchards. Although it can play a certain role in suppressing weeds and maintaining water and soil, it is easy to climb vines and entangle fruit trees, which will also affect the normal growth of fruit trees.

Embodiment 1

[0029] The test site was in Shuangding Town, Nanning City, Guangxi. The selected citrus orchard was a young orchard. The planting density of fruit trees in the orchard was 83 plants per mu, with a row spacing of 4 meters, a plant spacing of 2 meters, and a tree age of 1 year. Slope farmland, slope 21, soil It is a red soil. The basic physical and chemical properties of the soil between rows of the citrus orchard were determined before the test, pH 6.46, and 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 pattern is 3 rows of edamame between citrus rows + 2 rows of lab beans.

[0030] Specific steps are as follows:

[0031] (1) Green manure sowing

[0032] (1) Sowing of Shan Maodou: remove the weeds in the citrus orchard before sowing; sowing on March 26, 2017, soaking Shan Maodou in warm water at 80°C for 2-3 minutes before sowing. Use hole planting, the planting position is more than 100cm...

Embodiment 2

[0042] The test site was the same as Example 1. In Shuangding Town, Nanning City, Guangxi, the selected citrus orchard was a young orchard. The planting density of fruit trees in the orchard was 83 trees per acre, the row spacing was 4 meters, the plant spacing was 2 meters, and the tree age was 2 years. With a slope of 21, the planting pattern is the pattern of 2 rows of edamame +1 row of lab beans between citrus rows.

[0043] Including the following steps:

[0044] (1) Green manure sowing

[0045] (1) Sowing of Shan Maodou: remove the weeds in the citrus orchard before sowing; sowing on March 26, 2017, soaking Shan Maodou in 80℃ warm water for 3 minutes before sowing. Use hole planting, the planting position is more than 100cm away from the trunk of the fruit tree, the planting row spacing is 30cm, the plant spacing is 20cm, the planting depth is 2-4cm, each hole is 3-4 seeds, and the soil is covered after planting;

[0046] (2) Sown Laba Bean: Sow Laba Bean at the diagonal line b...

Abstract

The invention belongs to the technical field of fruit tree cultivation management and particularly provides a method for improving citrus orchard ecological environment by interplanting Tephrosia candida and Dolichos lablab L.. The method comprises the steps of green manure seeding, cultivation management, and cutting and utilization. According to the invention, by interplanting the perennial erect green manure crop Tephrosia candida and the entwined green manure cropDolichos lablab L. between rows of a citrus orchard, the Dolichos lablab L. is guided to climb on the Tephrosia candida, the Dolichos lablab L. is prevented from climbing on and winding around fruit trees, the amount of green manure and grass is increased, at the same time, by regular cutting, the grass covers the surface of soil, the surface temperature is further reduced, the organic matter content of the soil of the citrus orchard is improved, water and soil are preserved, weeds are inhibited, therefore, the fertilizerapplication is reduced, the ecological environment of the citrus orchard is improved, the fruit quality 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 interplanting wild bean and Labyrinth to improve the ecological environment of the citrus orchard. Background technique [0002] Tephrosia candida (Tephrosia candida) is a small perennial evergreen shrub of the genus Leguminosae, which is resistant to acid, barren, drought, mowing, and nitrogen fixation. It is suitable for planting on hilly red soil slopes. [0003] Lablab bean (Dolichos lablab L.), also known as eyebrow bean and lentil, is an annual or perennial herbaceous plant in the genus Lablab of the leguminous butterfly subfamily of the bean family. Raba bean stems have certain entanglement, large fresh biomass, good lushness, barren tolerance, drought tolerance, mowing and nitrogen fixation. At present, fruit farmers blindly apply a large amount of chemical fertilizers in pursuit of high yields and spray herbicides to suppress...
