A composition for improving the air permeability of orchard soil and its application method

Abstract

The invention discloses a composition for improving the breathability of orchard soil and an application method thereof. The composition is non-toxic and non-polluting, and specifically, the composition is a mixture of granular polyacrylamide, corncob particles and carbon residues; meanwhile, according to the composition for improving the breathability of the orchard soil and the application method thereof, a hole storage technology is adopted, the composition for improving the breathability of the orchard soil is filled in soil holes close to tree watering ranges in a centralized mode, a layer of 'water storage and breathable layer' is formed, water is conserved, a certain amount of gas can be effectively stored, at the same time, because of the water absorption and dehydration effects of granular polyacrylamide, the corncob particles and the carbon residues, the soil at root areas of fruit trees is loosened, the breathability of the soil at the root areas is improved, and the oxygen content of the soil at the root areas is increased; the root-system vigor of the fruit trees is improved, and the growth and development of plants are promoted.

Description

technical field [0001] The invention belongs to the technical field of orchard cultivation, and in particular relates to a composition for improving the air permeability of orchard soil and an application method thereof. Background technique [0002] Soil is the foundation of plant growth. Plants are rooted in the soil. Root growth requires the soil to provide sufficient mineral nutrients and water, as well as good air permeability to ensure the normal respiration of plant roots. Soil oxygen content is also an indicator for evaluating soil fertility. [0003] At present, in the production of fruit trees, due to improper cultivation and management measures, soil compaction and soil permeability become poor. In areas with heavy soil, the soil has poor air permeability. Coupled with the influence of respiration of plant roots and soil microorganisms, soil CO 2 The concentration is very high, and the O 2 The concentration is less, causing poor root soil ventilation or insuff...

Problems solved by technology

[0004] The traditional method of improving soil air permeability is mostly to improve soil structure and soil air permeability by adding organic fertilizers. For example, the patent "compound fertilizer for improving soil air permeability" (application number: 2016105319597) discloses a method of using ten A compound fertilizer prepared from various compounds such as sodium dialkylbenzenesulfonate, boric acid, sodium tripolyphosphate, and sodium hydroxide. The compound fertilizer can improve the soil aggregate structure and increase the air permeability of the soil. It can promote the growth of plants; however, this method requires a lot of manpower and material resources, and the cost is high, and it needs to apply organic fertilizers year after year to maintain the effect; at the same time, applying so many compounds in the soil may cause soil pH, microbial community Changes in physiological and biochemical indicators, such as biochemical indicators, will bring potential negative impacts; or improve soil permeability through deep plowing in the park. This method is the most traditional and simple, but because it does not make any changes to the nature of the soil itself, it requires long-term deep plowing for years. To maintain the effect, it takes a lot of manpower and material resources
