Method for improving orchard soil

Abstract

The invention discloses a method for improving orchard soil. The method comprises the following steps: sowing wild mung beans in an orchard in late May with the growth period from May to October, sowing wild mung beans in the mid-late October with the growth period from October to June the following year. The orchard is covered by leguminous forage all year long for nitrogen fixation and soil amelioration. Withered forage and straws are utilized for covering the orchard and help improve soil fertility after decaying so that the content of organic matters is increased. The forage and straws are different from leguminous ever-green grass varieties. Fewer weeds grow in the orchard.

Description

technical field [0001] The invention relates to a soil improvement method, in particular to a method for improving orchard soil. Background technique [0002] At present, high-efficiency economic forest fruit has become a hot pursuit object in the whole country, and various economic forest fruits have fully bloomed in rural areas. However, the technical level of economic forest fruit production is uneven, and the knowledge of orchard soil cultivation is almost zero. At the same time, due to the shortage of labor Nervous, the orchard is either overgrown with weeds, or is cleared with herbicides, and the whole orchard looks bare, which leads to soil compaction in the orchard, nutrient imbalance, and extreme deterioration of the soil ecological environment. Decline, the quality of fruit is reduced, seriously affecting the economic benefits of fruit farmers. [0003] Based on the above problems, a new cultivation mode, grass cultivation, has emerged in recent years. Orchard gr...

Problems solved by technology

[0005] However, there are the following problems in grass cultivation. One, the model applicability of grass cultivation is low, and it is greatly affected by different soil environments and trees planted in orchards.

2. It is difficult to choose the combination of grass species for grass cultivation. When the grass species is not selected properly, it will cause slow growth of fruit trees in the orchard, the introduction of diseases and insect pests and further deterioration of the soil environment, and the effect of improving the soil cannot be achieved.
