Method for increasing the soil fertility of orchard

Abstract

The invention discloses a method for increasing the soil fertility of an orchard. The method comprises the following steps: (1) land preparation, wherein the rows of fruit trees are plowed 5 -7 days before the sowing of Vicia villosa; (2) seed pre-treatment, wherein Vicia villosa seeds are soaked in warm water, floating impurities are removed, and the Vicia villosa seeds are air-dried for standbyapplication; (3) sowing, wherein the Vicia villosa seeds are sowed in spring or autumn, clearing areas or mulch coverage areas between the rows of fruit trees are left, and the Vicia villosa seeds aresowed in other areas; (4) management after sowing, wherein in the second year after sowing, in mid-March each year, fertilizers are applied to the rows of fruit trees, pesticides are sprayed, and theVicia villosa plants naturally rot. The method can reduce the labor for the soil management of an orchard, improve the ecological environment of the orchard, increase the species diversity, reduce the pest occurrence index, increase the organic matter content of the soil in the orchard, improve the intrinsic varieties of fruits, and achieve sustainable and healthy development of the orchard.

Description

technical field [0001] The invention belongs to the technical field of fruit tree planting, and in particular relates to a method for fertilizing soil fertility in orchards. Background technique [0002] This year, some advanced fruit production countries in Europe, America and Asia have adopted the soil management system of growing grass in orchards. Grass has been grown in the whole orchard or between rows for many years, the soil is loose and airy, and the organic matter content is kept at 5%-7%, which keeps the trees healthy. , the disease index of orchard diseases and insect pests is low, the quality of the produced fruit is high, and the market competitiveness is strong. However, the vast majority of orchards in our country use a large amount of chemical fertilizers, coupled with insufficient and expensive organic fertilizer sources, resulting in the organic matter content of the orchard soil. It is decreasing year by year, showing a trend of barrenness, soil quality a...

[0002] This year, some advanced fruit production countries in Europe, America and Asia have adopted the soil management system of growing grass in orchards. Grass has been grown in the whole orchard or between rows for many years, the soil is loose and airy, and the organic matter content is kept at 5%-7%, which keeps the trees healthy. , the disease index of orchard diseases and insect pests is low, the quality of the produced fruit is high, and the market competitiveness is strong. However, the vast majority of orchards in our country use a large amount of chemical fertilizers, coupled with insufficient and expensive organic fertilizer sources, resulting in the organic matter content of the orchard soil. It is decreasing year by year, showing a trend of barrenness, soil quality and sustainable development ability decline, resulting in the decrease of comprehensive soil fertility and the increase of fruit tree deficiency, which directly affects the yie
