Intercropping pasture in orchard is actually a soil management method. Pasture intercropping with fruit trees is generally combined with animal husbandry to form a benign three-dimensional planting and breeding cycle model of ecological agriculture. At present, many places are gradually popularizing interplanting high-quality pasture in orchards, vigorously developing under-forest farming, forming a virtuous cycle model of sustainable ecological agriculture of "planting grass in orchards-raising livestock with pasture-fermenting livestock manure-fertilizing fields with biogas slurry", and realizing the healthy and coordinated development of planting and breeding industry and ecological civilization construction.
Advantages of interplanting forage in orchard;
1: Intercropping pasture in orchard can prevent soil loss or blow away to increase the supply of organic matter caused by rainstorm, rainstorm or storm, and effectively prevent soil erosion.
The grass planted in the orchard has deep roots and luxuriant leaves. After withering, all the grass becomes organic matter, which exists on the surface and underground, making the soil fertile.
3. It can agglomerate the soil, enhance the air permeability and water permeability of the soil, improve the physical properties of the soil, and save labor for farming and weeding.
In order to give full play to the advantages of intercropping pasture in orchard, the selection of pasture varieties is very important. Forage has strong adaptability, no pests and diseases with fruit trees, good shade tolerance and short plant type. In China, leguminous forage is the best choice. Leguminous forage contains high protein, calcium, other mineral elements and vitamins. Another feature of leguminous forage is that it has nodules, which can fix free nitrogen in the air, increase the protein content of forage and nitrogen-containing substances in the soil, meet the needs of livestock for protein and improve soil fertility.
