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...
