Embodiment 1

[0024] This embodiment provides a soil conditioner, comprising the following raw material components in parts by weight: 65 g of calcium magnesium phosphate fertilizer, 20 g of humic acid, and 2 g of trace elements; the trace elements are composed of 1 g of zinc sulfate heptahydrate and 1 g of borax.

[0025] The preparation method of above-mentioned soil conditioner specifically comprises the steps:

[0026] At first get each raw material by above-mentioned parts by weight, add concentration in humic acid wherein and be that 2% potassium hydroxide solution is activated, and potassium hydroxide solution accounts for 30% of total amount, and humic acid is activated; Calcium magnesium phosphate fertilizer and trace elements are added in proportion to the final humic acid, mixed thoroughly and evenly; finally crushed, sieved and granulated to obtain the soil conditioner.

[0027] Among the above-mentioned soil conditioners, potassium humate or potassium fulvic acid is used as a c...

Embodiment 2

[0030] This embodiment provides a soil conditioner, comprising the following raw material components in parts by weight: 65 g of calcium magnesium phosphate fertilizer, 20 g of humic acid, and 2 g of trace elements; the trace elements are composed of 1 g of zinc sulfate heptahydrate and 1 g of borax.

[0031] The preparation method of above-mentioned soil conditioner specifically comprises the steps:

[0032] At first get each raw material by above-mentioned parts by weight, add concentration in humic acid wherein and be that 8% potassium hydroxide solution is activated, and potassium hydroxide solution accounts for 40% of total amount, and humic acid is activated; Calcium magnesium phosphate fertilizer and trace elements are added in proportion to the final humic acid, mixed thoroughly and evenly; finally crushed, sieved and granulated to obtain the soil conditioner.

Embodiment 3

[0034] This embodiment provides a soil conditioner, comprising the following raw material components in parts by weight: 80 g of calcium magnesium phosphate fertilizer, 30 g of humic acid, and 3 g of trace elements; the trace elements are composed of 1.5 g of zinc sulfate heptahydrate and 1.5 g of borax.

[0035] The specific preparation process of the above soil conditioner is the same as the method provided in Example 1, the only difference is that the raw material formula is different, which will not be discussed one by one here.

Abstract

The invention discloses a soil conditioner and a preparation method thereof. The soil conditioner is prepared from, by weight, 67-78 parts of calcium magnesium phosphate fertilizer, 20-30 parts of potassium fulvate and 2-3 parts of microelements, wherein the microelements are zinc and boron. The soil conditioner provided by the invention contains the calcium magnesium phosphate fertilizer and the trace elements zinc and boron, and potassium humate or potassium fulvate is used as a chelating agent, so that the medium elements calcium magnesium silicon and the trace elements zinc and boron can be chelated to a great extent, the medium and trace elements are converted into a chelated state, the exchange capacity of positive ions can be remarkably improved, the fertilizer efficiency can be enhanced and soil solidification can be reduced while nutrients of crops are met. By using activated potassium humate or potassium fulvate, the potassium cation exchange capacity in the soil is increased, the soil acidity and alkalinity are adjusted, the formation of a soil aggregate structure is promoted, the nutrient deficiency symptom of crops is prevented and treated, the disease resistance of the crops is enhanced, the yield of the crops is increased, and the quality of the crops is improved.

Description

technical field [0001] The invention relates to a soil conditioner and a preparation method thereof. Background technique [0002] Due to the extensive use of chemical fertilizers and pesticides in agricultural production, soil compaction, soil acidification, and soil salinization have been aggravated, posing a serious threat to the agricultural ecological environment. In particular, the special environmental conditions of protected cultivation, the blindness of human management and utilization, and the unreasonable fertilization system lead to more serious deterioration of soil physical and chemical properties, and the soil production capacity is declining. Therefore, people began to use soil conditioners to improve soil conditions and improve soil fertility. Contents of the invention [0003] The technical problem mainly solved by the invention is how to provide a soil conditioner capable of improving soil condition and soil fertility and a preparation method thereof. ...
