Ecological soil conditioner for acid soil improvement and preparation method of ecological soil conditioner

Abstract

The invention relates to the technical field of soil improvement, in particular to an ecological soil conditioner for acid soil improvement and a preparation method thereof. The ecological soil conditioner comprises the following raw materials: carbonized vinasse, shell powder, modified carbonized bone meal, modified rice bran, bamboo charcoal particles, a dispersing agent, a water-retaining agent, biological zymophyte and a compound microbial agent. The raw material formula is scientific and reasonable; the raw materials are blended according to a reasonable proportion, so that effective components of different raw materials are fully fused and complemented, and the ecological soil conditioner has high economic benefits, social benefits and popularization value, is safe and environment-friendly; the carbonized vinasse, bone meal and rice bran are adopted as main raw materials, so that the ecological soil conditioner has no pollution to crops, human bodies and the environment, is rich in raw material source, low in cost and beneficial to industrial production and large-scale application; the defect that the cost is high when organic fertilizer is used for improving acid soil at present is overcome; the acid soil can be effectively improved; the soil micro-ecological environment can be improved; and soil disease microorganisms can be killed.

Description

technical field [0001] The invention relates to the technical field of soil improvement, in particular to an ecological soil conditioner for acid soil improvement and a preparation method thereof. Background technique [0002] The main types of acidic soil are brick red soil, red red soil, red soil, and yellow red soil, which are distributed in zonal areas. Affected by soil-forming parent material and soil-forming factors, it has the characteristics of "acid, barren, poisonous, plate, and leakage". When crops are cultivated in the acidic soil of the dry land in the south, the permeability of the protoplasmic membrane in some plants will be destroyed, resulting in the reduction of the absorption of calcium, magnesium, potassium and other elements by the crops, and the agricultural output rate is low. However, this type of soil is widely distributed as agricultural land, with a large area and great potential for production. By improving and fertilizing it through the applica...

Problems solved by technology

[0003] Soil conditioners traditionally used to improve acidic soil are mainly lime and alkaline industrial waste. Although these substances can reduce soil acidity, excessive or uneven application will cause local calcification, damage soil microorganisms, affect soil structure and cannot At the same time, it meets the needs of crops for medium and trace element fertilizers

In addition, some people use alkali slag, mushroom slag, calcium magnesium phosphate fertilizer, etc. as improvement materials for acidic soil, and have achieved certain improvement and yield increase effects. Disadvantages such as high transportation costs make it difficult to popularize and apply in large areas in agricultural production
