Soil conditioner capable of improving soil fertility and preparation method thereof

Abstract

The invention discloses a soil conditioner capable of improving the soil fertility. The soil conditioner is characterized by being prepared from the following raw materials in parts by weight: 6 to 8 parts of ferric sodium edelate, 10 to 15 parts of disodium hydrogen phosphate, 20 to 30 parts of limestone powder, 12 to 25 parts of bamboo powder, 5 to 15 parts of sodium octaborate tetrahydrate, 10 to 20 parts of sugar alcohols magnesium, 10 to 13 parts of crop straw powder, 11 to 14 parts of excrements of livestocks, 5 to 10 parts of potassium chloride, 4 to 8 parts of calcium powder, 1 to 2 parts of alkaloid, 5 to 10 parts of calcium superphosphate and 5 to 7 parts of polymalic acid ester. When the soil conditioner disclosed by the invention is used for planting plants, the usage of a bactericide can be reduced; the pH value of soil can be improved quickly; the organic content in the soil can be increased, and meanwhile, the bamboo powder change into humic acid under the action of ferric sodium edelate and sugar alcohols magnesium, and the granular structure of the soil can be continuously improved; the growth of garden plants can be promoted, and absorption of toxic metal to garden plants in the soil is improved.

Description

technical field [0001] The invention relates to the technical field of soil improvement, in particular to a preparation method of a soil conditioner for improving soil fertility. Background technique [0002] Soil is the loose surface layer on which plants can grow on the earth's land, and fertility is the basic characteristic of soil. There are many basic soil properties that affect fertility, including: the thickness of the plow layer, the texture and structure of the plow layer, the content of organic matter in the soil, the content of nutrients such as nitrogen, phosphorus, and potassium in the soil, and the pH of the soil. However, the long-term application of chemical fertilizers changes the soil properties, and the soil environment is gradually unsuitable for crop growth. At the same time, the current soil acidification is serious, which reduces the internal pH of the soil, reduces the basic cations, and increases the activity of toxic metal ions, resulting in extreme...

Problems solved by technology

However, the long-term application of chemical fertilizers changes the soil properties, and the soil environment is gradually unsuitable for crop growth. At the same time, the current soil acidification is serious, which reduces the internal pH of the soil, reduces the basic cations, and increases the activity of toxic metal ions, resulting in extremely strong soil viscosity. , the content of soil organic matter is reduced, and the soil is densely compacted to cause less air and poor permeability, or the desertification and salinization of the soil are relatively serious. Therefore, there is an urgent need for a method that can effectively adjust the soil pH value, increase the content of soil organic matter, and improve the structure of soil aggregates. Soil amendments that change the form of toxic metals
