Intelligent ecological planting method for soil improvement and grass control of selenium-rich orchard in hilly and mountainous areas

Abstract

The invention provides an intelligent ecological planting method for soil improvement and grass control of a selenium-rich orchard in hilly and mountainous areas, and relates to the field of ecological agriculture and forestry breeding. An earthworm breeding technology and an under-forest chicken raising mode are combined, a selenium-rich wormcast organic fertilizer is applied on the aspect of fertilizer addition, selenium-rich agricultural products are produced, the advantages of the selenium-rich agricultural products are fully utilized, and regional economic development is driven. The method can effectively solve the problems that the requirement for water and fertilizer, especially nitrogen fertilizer, needs to be considered during peach tree planting and peach trees are fear of cold, meanwhile, selenium-rich earthworms are treated subsequently, and good economic benefits are achieved either the selenium-rich earthworms are processed into earthworm powder or sold to pharmaceutical factories.

Description

technical field [0001] The invention relates to the field of ecological agriculture and forestry breeding, in particular to an intelligent ecological planting method for improving soil and controlling grass in selenium-enriched orchards in hilly mountainous areas. Background technique [0002] The mountains in the Chaohu Lake Basin are mostly low mountains and hills, and the soil is mostly red sandy soil. The parent material of the red sandy soil is weathered sandstone. It is cultivated soil developed from sandy red soil through reclamation and dry farming. The thickness of the cultivated layer is different, the texture is sandy soil, the soil color is mainly orange, the topsoil is dark yellow orange, the hue is 7.5-10YR, the brightness is 5-6, the saturation is 3-4, acid to slightly acidic, pH is mostly below 6.5, organic matter , total phosphorus, and total potassium are all low, and the cation exchange capacity is only about 5me / 100g soil. Due to its high sand content an...

Problems solved by technology

However, this method is not economically realistic for large-scale soil improvement

The colloidal colloid of humus in the soil with additional organic fertilizers is stronger than that of sand grains. Increasing the application of organic fertilizers can change the unfavorable properties of loose and unstructured sandy soil, improve the ability to retain water and fertilizer, and increase soil nutrients. Although it can effectively improve soil quality, but Effects are slow, making it difficult to produce results quickly
