[0033] The peat in the embodiment is low-level natural peat with a pH value of 5.0, and contains the following components in mass percentage: more than 16% of organic matter, 14% of humic acid, and more than 3% of the total amount of nitrogen, phosphorus, and potassium.

[0034] The straw material is a mixture of corn stalk and wheat stalk, dried and crushed to about 80 mesh.

[0035] Quicklime is used as the lime material.

[0036] Preferably, the bone meal is animal bone meal, crushed to 60-100 mesh.

[0037] The preparation method includes the following steps:

[0038] Firstly, the activated EM bacterial agent is activated and cultured from the EM bacterial agent stock solution, and 1 part of the EM bacterial agent stock solution, 1 part of brown sugar and 100 parts of water are mixed according ...

Abstract

The invention discloses an acidic soil conditioner and a preparation method thereof. The acidic soil conditioner is prepared from the following raw materials in parts by weight: 50 to 70 parts of peat, 40 to 70 parts of straw substance, 10 to 20 parts of limy substance, 10 to 30 parts of zeolite, 10 to 20 parts of bone meal and 2 percent to 3 percent of an activating EM bacterium agent; the preparation method of the acidic soil conditioner comprises: stirring and mixing all the raw materials except the activating EM bacterium agent in parts by weight; stirring and spraying water to dilute the activating EM bacterium agent; adjusting the moisture content of the materials; covering the materials, but not sealing; uncovering a film every day for ventilation; turning and adding the water for one time; after turning and adding the water, fermenting; drying fermented materials and crushing and sieving to obtain an undersized material, namely the acidic soil conditioner. The acidic soil conditioner provided by the invention can be used for remarkably reducing the acidity of red and yellow soil, conditioning a soil structure, increasing the content of organic matters in the soil, improving the soil fertility and accelerating the growth of plants, and has the advantages of low cost, simplicity in operation, environment friendliness, relatively high bioactivity and the like.

Description

technical field [0001] The invention belongs to the field of soil conditioners, in particular to an acidic soil conditioner and a preparation method thereof. Background technique [0002] The red-yellow soil is mainly distributed in the low-latitude areas of Africa, Asia, Oceania, and South and North America. It is roughly limited to 30° north and south latitude. It spreads across 16 provinces in southern my country, with a total area of ​​261.506 million mu, accounting for about 20% of the country's land area. , of which Zhejiang has 49.279 million mu, accounting for nearly one-fifth. Red-yellow soil is poor in nutrients, manifested as low organic matter content, Ca, Mg and P deficiency or Al toxicity. In addition, the red yellow soil is highly acidic, which is not conducive to the reproduction of microorganisms, hinders the mineralization, decomposition and transformation of soil nutrients, and the low fertility level affects the normal growth of plants. Due to the proble...
