Method for inter-planting forage grass in orchards at karst rock desertification region

Abstract

The invention discloses a method for inter-planting forage grass in orchards at a karst rock desertification region, in particular a method for inter-planting leguminous forage grass and gramineous forage grass below fruit trees in the orchards, wherein the mixing weight ratio of the leguminous forage grass to the gramineous forage grass is (5-7):(3-5), and the seeding rate is 1.5-2.0 kg/mu. According to the method, the leguminous forage grass and the gramineous forage grass are selected and sowed in a mixed way according to the characteristics of high yield and low crude protein content of the gramineous forage grass and high crude protein content of the leguminous forage grass, so that the yield and the quality of the forage grass are improved, and the palatability of the forage grass and the absorption of livestock to the nutrients of the forage grass are enhanced; by performing mixed sowing on the leguminous forage grass and the gramineous forage grass according to a weight ratio of (5-7):(3-5) under fruit trees, the coverage ratio of land vegetation of the orchards is increased and water and soil loss is greatly reduced; and meanwhile, the soil fertility of the orchards can also be increased, the environment of the orchards is improved, the productivity of land is improved, and the aims of increasing the yield of fruit trees and the yield of the forage grass are fulfilled.

Description

technical field [0001] The invention relates to a method for interplanting grass in an orchard in a karst rocky desertification area, and belongs to the technical field of agricultural and forestry cultivation. Background technique [0002] Southwest karst mountains are a typical fragile ecosystem and one of the key ecological regions in China. Soil erosion and rocky desertification are becoming more and more serious in this area, and the degradation of ecological environment restricts the sustainable development of this area. Interplanting pasture in orchards in karst mountainous areas is an effective way to improve the karst ecological environment and help farmers get rid of poverty. On the one hand, it can develop the agricultural economy, and on the other hand, it can prevent the further deterioration of the ecological environment. [0003] At present, many karst areas plant fruit trees or establish orchards, such as establishing plum orchards, yellow orchards, and drag...

AI Technical Summary

Problems solved by technology

However, it is difficult to carry out large-scale promotion in karst rocky desertification areas with a high degree of land fragmentation and lack of water sources.

In addition, the above-mentioned technical method is mainly the method of interplanting a single herbage, sowing a single herb species is prone to diseases, and the consumption of a single species of herbage by livestock is not conducive to nutritional balance
