Biological water-soluble fertilizer and preparation method thereof

Abstract

The invention discloses a biological water-soluble fertilizer and a preparation method thereof.The preparation method comprises the following steps that S1, potassium humate powder and EM bacterial liquid are mixed according to the solid-to-liquid ratio of 150-200 g / L and stirred to be uniform, and a reaction solution with the pH value of 6-7 is obtained after standing and sufficient reaction; and S2, uniformly mixing the dried orange peel-Pu'er fermented tea soup fermentation water with the pH value of 4.0-5.5 with the reaction liquid obtained in the step S1 according to the ratio of (3-3.5): 1 to obtain a mixture, and standing for sufficient reaction to obtain the finished biological water-soluble fertilizer with the pH value of 6.0-6.5. The biological water-soluble fertilizer disclosed by the invention is weakly acidic, has obvious effects of increasing yield and income and improving crop quality, can fully replace traditional chemical fertilizers, and also has a good treatment effect on soil hardening, salinization and other problems; moreover, the fertilizer has good comprehensive effects of increasing yield, increasing income, improving crop quality and the like on southern plants or northern plants, and the use effect cannot be influenced by different plant varieties, different habits and different soil environments.

Description

technical field [0001] The invention relates to the field of agriculture, in particular to a biological water-soluble fertilizer and a preparation method thereof. Background technique [0002] Excessive use of chemical fertilizers over the years has caused soil acidification and water eutrophication, seriously affecting the soil quality of cultivated land, and the ecological environment has been damaged to a certain extent. The rise of chemical fertilizers has led farmers to overuse chemical fertilizers in the process of pursuing maximum yield per mu, which has seriously affected the quality of cultivated land. [0003] In recent years, the wide application of various chemical fertilizers and pesticides has brought great harm to the land and crops. Soil compaction, soil microbial environmental degradation, excessive pesticide residues and quality decline of crops are common. With the overuse of chemical fertilizers, soil quality has declined significantly everywhere. The s...

Problems solved by technology

[0005] However, the existing bio-organic fertilizers still have the disadvantages of long preparation period, high requirements on the fermentation environment, site and process, easy leakage and secondary pollution during the fermentation production process, high cost of additives required in the production process, and increased production and income. The effect is not obvious enough, and it takes a long time for the beneficial effect to be produced and stabilized. These shortcomings limit its large-scale, popularized use and production, and are also important reasons why the existing bio-organic fertilizers are still unable to shake the mainstream status of chemical fertilizers. reason
