Embodiment 1

[0034] A special fertilizer for corn, prepared from the following components in parts by weight: 18 parts of modified biochar, 40 parts of corn stalks, 25 parts of kitchen waste, 8 parts of tea leaves, 8 parts of potassium sulfate, and 1.5 parts of EM bacteria , 1 part of hydroxypropyl-β-cyclodextrin, 0.5 part of polydimethyldiallyl ammonium chloride;

[0035] The effective number of viable bacteria in EM bacteria is 1.0×10 8 individual / mL.

[0036] The specific preparation method is as follows:

[0037] Step 1, prepare modified biochar

[0038] Adding catalase with an enzyme activity of 10000 U / mL to the aqueous tannic acid solution with a pH value of 5.0, so that the mass concentration of catalase reaches 1%, to obtain a modified solution;

[0039] Soak the biochar in the modified solution, ultrasonically treat it at 35KHZ for 10 minutes, then activate it at 60°C for 2 hours, take it out and dry it after the activation, and obtain the modified biochar;

[0040] Step 2, w...

Embodiment 2

[0048] A special fertilizer for corn, prepared from the following components in parts by weight: 15 parts of modified biochar, 30 parts of corn stalks, 20 parts of kitchen waste, 10 parts of tea leaves, 5 parts of potassium chloride, and 1 part of EM bacteria 0.5 part of hydroxypropyl-β-cyclodextrin, 1 part of polydimethyldiallyl ammonium chloride;

[0049] The effective number of viable bacteria in EM bacteria is 1.0×10 9 individual / mL.

[0050] The preparation method is the same as that of Example 1, except that the formula in Example 1 is changed into that of Example 2.

Embodiment 3

[0052] A special fertilizer for corn, prepared from the following components in parts by weight: 20 parts of modified biochar, 50 parts of corn stalks, 30 parts of kitchen waste, 5 parts of tea leaves, 10 parts of potassium chloride, 2 parts of EM bacteria 0.5 part, 0.5 part of hydroxypropyl-β-cyclodextrin, 0.5 part of polydimethyldiallylammonium chloride;

[0053] The effective number of viable bacteria in EM bacteria is 1.0×10 10 individual / mL.

[0054] The preparation method is the same as in Example 1, except that the formula in Example 1 is changed into Example 3.

[0055] In order to further illustrate the effects of the present invention, the present invention also provides comparative examples, specifically as follows.

Abstract

The invention discloses a special fertilizer for corn. The special fertilizer for corn is prepared from, by weight, 15-20 parts of modified biochar, 30-50 parts of corn straw, 20-30 parts of kitchen waste, 5-10 parts of tea residues, 5-10 parts of a potassium fertilizer, 1-2 parts of a fermenting agent, 0.5-1 part of hydroxypropyl-beta-cyclodextrin and 0.5-1 part of polydimethyl diallyl ammonium chloride. In addition, the invention also provides a preparation method of the specific fertilizer for the corn. The prepared special fertilizer for the corn can significantly increase the content of organic carbon, nitrogen, phosphorus, potassium and other nutrient elements in the soil, increase the nutrient conversion rate and the number of beneficial microorganisms, promote the soil remediation,improve the soil fertility, increase the yield of summer corn, promote the increasing income, and have broad application prospects.

Description

technical field [0001] The invention belongs to the technical field of agricultural fertilizer preparation, and in particular relates to a special fertilizer for corn and a preparation method thereof. Background technique [0002] The yield of summer corn in the Huang-Huai-Hai region of my country generally hovers around 500-600 kg per mu. One of the reasons affecting the yield of summer corn is that the application of chemical fertilizers is unreasonable and excessive, which leads to a decline in the physical and chemical properties of the soil and a decrease in the utilization rate of fertilizers. . In recent years, the application of chemical fertilizers in summer corn production areas has become more and more extensive. Although chemical fertilizers can increase the yield of crops in a certain period of time, the long-term high-fertilization agricultural production mode has made the soil harden, the cultivated layer becomes shallower, and the soil physical and chemical pr...
