Soil cultivation agent and preparation method thereof

Abstract

The invention provides a soil cultivation agent and a preparation method thereof. The soil cultivation agent is prepared from the following components in parts by weight: 2-6 parts of flaxseed gum, 50-150 parts of organic fertilizer, 6-18 parts of a water retaining agent, 2-6 parts of humic acid, and 800-2400 parts of water. The preparation method of the soil cultivation agent comprises the following steps: using flaxseed meal as a raw material, and treating the flaxseed meal to obtain the flaxseed gum; mechanically crushing and sieving the organic fertilizer and the humic acid respectively toobtain powdery organic fertilizer and powdery humic acid; mixing the flaxseed gum, the water retaining agent, and the water with the powdery organic fertilizer and the powdery humic acid, and stirring for mixing uniformly to obtain the soil cultivation agent. The soil cultivation agent and the preparation method thereof provided by the invention are suitable for planting sand-adapted arbors and shrubs in arid and semi-arid desert areas under no irrigation conditions.

Description

technical field [0001] The application relates to the technical field of soil restoration and improvement, in particular to a soil cultivation agent and a preparation method thereof. Background technique [0002] my country has a vast desert area, mainly distributed in arid and semi-arid areas. It belongs to the temperate continental monsoon climate. The soil evaporation is far greater than the precipitation, and the desert soil is severely aeolian, with high content of coarse-grained materials, large porosity, and water retention. Weak fertilizer retention capacity and poor nutrients make it difficult for sandy (economic) trees or shrubs planted in the process of desertification control and desert economic construction to survive. [0003] At present, in the process of desertification control and desert economic forest construction in China, the method of planting wind-proof and sand-fixing and sand-suitable economic trees or shrubs is mainly planted by digging holes manuall...

AI Technical Summary

Problems solved by technology

[0003] At present, in the process of desertification control and desert economic forest construction in China, the method of planting wind-proof and sand-fixing and sand-suitable economic trees or shrubs is mainly planted by digging holes manually in spring or autumn, and the main method of watering wind-proof and sand-fixing forests is to use water trucks for watering. Irrigation is very difficult. Most of them can only be irrigated once when they are planted, and almost all of the rest rely on natural rainfall to maintain growth, resulting in low survival rate of afforestation and increased cost of repeated replanting afforestation, which seriously affects the process of desertification prevention and control in my country

However, sand-suitable economic trees or shrubs need to be equipped with a complete water system for regular irrigation. Due to the unique geographical and climate environment in which the evaporation of the desert is much greater than the precipitation, a large amount of groundwater needs to be used for irrigation, and the utilization rate of water resources is low, and the cost of irrigation is high. Seriously restrict the construction of sandy economic trees or shrubs in desert areas

Existing seed coatings, drought-resistant nutrients, and foliar sprays have relatively high processing costs, complex manufacturing processes, and contain chemical components that easily pollute the soil and are easily affected by the natural climate of the desert.
