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 yield of fruit trees and fruit quality, weakens market competitiveness, and seriously restricts the sustainable development of the fruit industry. sustainable development

[0003] The reason for the above is that on the one hand, orchard farmers have deep-rooted traditional cultivation concepts, believing that long grass in orchards will compete with fruit trees for fertilizer and water, and insist on adopting the orchard soil management mode of clear tillage. The importance of the growth and development of fruit trees, trying to fertilize the soil by growing grass in the orchard, but due to failure to select suitable grass species or lack of supporting equipment and technology, resulting in the increase of grass species in the short term or aggravating the occurrence of fruit tree diseases and insect pests, and finally had to Abandoning the method of growing grass to fertilize orchard soil restricts the application and promotion of growing grass in orchards
