A kind of anti-drought soil conditioner for promoting growth and its preparation method and application method

Abstract

The present invention discloses a drought-resistant growth-promotion soil conditioner and a preparation method and use thereof, and the soil conditioner comprises the following materials: 2g of manganese sulfate, 0.6g of ammonium molybdate, 4g of rare earth elements, 4g of boric acid, 3g of sodium lauryl sulfate, 20g of urea, 4g of fulvic acid, 0.5g of diethyl aminoethyl hexanoate, 11g of compound amino acids, 6.25g of potassium dihydrogen phosphate, 235ml of ammonia water with the mass percentage concentration of 25%, 21g of a first aquasorb, 9g of a second aquasorb, 7g of Xerocomus chrysenteron microbial inoculums, 5g of phosphate-solubilizing potassium-releasing bacteria and 5g of biochar. The drought-resistant growth-promotion soil conditioner increases soil nutrients, improves the water retention capacity of soil, strengthens water and nutrients absorption capacity of plant roots, overall improves soil in arid areas and semi-arid zones, promotes plant growth, and substantially increases the survival rate and growth rate of plants.

Description

technical field [0001] The invention relates to the technical field of soil improvement suitable for plant growth, in particular to a drought-resistant and growth-promoting soil improver, a preparation method and a use method thereof, which are suitable for poplars in arid or semi-arid regions. Background technique [0002] Water and nutrients in the soil are necessary conditions for plant growth and development, but most of the land in our country belongs to the arid area (the arid area usually refers to the area with an average annual precipitation below 250mm) or semi-arid area (semi-arid area Usually refers to areas with an average annual precipitation of 250-550mm or less), these areas not only have less precipitation, but also have a large amount of evaporation, and the nutrients in the soil are seriously deficient, so these areas are difficult to meet the needs of plant growth and development. [0003] Take the semi-arid Loess Plateau region as an example, where preci...

Problems solved by technology

In the prior art, in order to solve the problems affecting plant growth such as low rainfall, serious soil erosion, and serious deterioration of soil quality in the Loess Plateau, most of the methods of applying trace element fertilizers to the soil are used, but this method can only be used in a short period of time. Increase the content of nutrient elements in the soil, the function is single, the effect is limited, and the nutrient elements in the soil are easily lost in the Loess Plateau area
