Embodiment 1

[0018] A soil conditioner, proportioned according to the following parts by weight: 48 parts of dolomite calcined product, 40 parts of decomposed livestock and poultry manure, 5 parts of magnesium ammonium phosphate, and 5 parts of Bacillus licheniformis agent;

[0019] The livestock and poultry excrement is at least one excrement of livestock and poultry among chickens, ducks, geese, pigs, cattle, horses and sheep.

[0020] The method for preparing the above-mentioned soil conditioner, the preparation steps are as follows:

[0021] 1) The dolomite material is crushed and then calcined. The calcining condition is to carry out 1 hour at 1200° C., and then pass through an 80-mesh sieve to obtain a dolomite calcined product;

[0022] 2) The decomposed livestock and poultry manure is sprayed and granulated, put into a dryer for drying, and pass through an 80-mesh sieve;

[0023] 3) Mix 48 parts of dolomite calcined product and 40 parts of decomposed livestock and poultry manure a...

Embodiment 2

[0026] A soil conditioner, according to the following proportions by weight: 20 parts of magnesite calcined products, 22 parts of dolomite calcined products, 32 parts of decomposed livestock and poultry manure, 7 parts of magnesium ammonium phosphate, 2 parts of Bacillus licheniformis agent, 1 part of Bacillus subtilis agent;

[0027] The livestock and poultry excrement is at least one excrement of livestock and poultry among chickens, ducks, geese, pigs, cattle, horses and sheep.

[0028] The method for preparing the above-mentioned soil conditioner, the preparation steps are as follows:

[0029] 1) The magnesite ore material and the dolomite material are crushed and then calcined respectively. The calcining conditions are all carried out at 1000° C. for 2 hours, and then passed through an 80-mesh sieve to obtain a magnesite ore calcined product and a dolomite calcined product;

[0030] 3) According to the proportion, 20 parts of magnesite calcined products, 22 parts of dolo...

Embodiment 3

[0033] A soil conditioner, proportioned according to the following parts by weight: 35 parts of dolomite calcined product, 27 parts of decomposed livestock and poultry manure, 5 parts of magnesium ammonium phosphate, 2 parts of Bacillus licheniformis agent, and 1 part of Bacillus subtilis agent;

[0034] The livestock and poultry excrement is at least one excrement of livestock and poultry among chickens, ducks, geese, pigs, cattle, horses and sheep.

[0035] The method for preparing the above-mentioned soil conditioner, the preparation steps are as follows:

[0036] 1) The dolomite material is crushed and then calcined. The calcining conditions are all at 1000°C for 1.5h, and then passed through an 80-mesh sieve to obtain a dolomite calcined product;

[0037] 2) The decomposed livestock and poultry manure is sprayed and granulated, put into a dryer for drying, and pass through an 80-mesh sieve;

[0038] 3) Fully mix 35 parts of dolomite calcined product and 27 parts of decom...

Abstract

The invention relates to a soil conditioner which comprises the following components in parts by mass: 35-48 parts of mineral materials, 25-40 parts of decaying livestock and poultry manure, 5-10 parts of magnesium ammonium phosphate and 2-5 parts of microbial agents. The invention also provides a method for preparing the soil conditioner, wherein the method comprises the following steps of: 1) crushing the mineral materials and forging at 900-1200 DEG C for 1-2 hours, sieving by an 80-mesh sieve, thereby obtaining a forged mineral product; 2) carrying out spray granulation on the decaying livestock and poultry manure, putting into a drying machine, drying, and sieving by an 80-meshes sieve; 3) mixing the 35-48 parts of forged mineral product and 25-40 parts of decaying livestock and poultry manure uniformly for the sieved material in proportion in the steps above, thereby obtaining a mixed material; and 4) adding 5-10 parts of magnesium ammonium phosphate and 2-5 parts of microbial agents in the mixed material obtained from the step 3), mixing uniformly, crushing, and sieving in an 100-mesh sieve, thereby obtaining the soil conditioner. The soil conditioner provided by the invention can be used for modifying soil, intensifying the disease-prevention capability, and improving the crop yield, the quality of agricultural products and the fertility of soil.

Description

technical field [0001] The invention relates to a soil conditioner, and also relates to a preparation method of the soil conditioner. Background technique [0002] China is a large agricultural country, and the use of chemical fertilizers and chemical pesticides is increasing year by year. As a result, China's agricultural ecological environment is gradually deteriorating. The decline in soil quality poses an increasing threat to China's agriculture. In order to improve soil quality and strengthen soil functions, It is necessary to condition the structure and fertility properties of the soil. [0003] Magnesium is the basic element and the most active component of various enzymes in the whole metabolic process of plants. It has a good effect on promoting plant resistance to disease, cold, and drought. It is also an improver for acidic and weakly alkaline soils. Improving yield and crop quality has a direct and important effect. Magnesium deficiency in plants will lead to d...
