Embodiment 1

[0027] Example 1 Preparation of New Multifunctional Compound Microbial Fertilizer

[0028] The ratio is: 20 parts of microbial agent, 10 parts of biochar, 10 parts of pyrethrum powder, 30 parts of urea, 12 parts of monoammonium phosphate, 8 parts of potassium chloride, 5 parts of biochemical fulvic acid, 2 parts of EDTA chelated trace elements .

[0029] Preparation:

[0030] 1) Microbial agent preparation: Bacillus megaterium, Bacillus peptone-like, Paenibacillus nitrogen-fixing, and Bacillus subtilis were separately cultured and fermented, and the fermented bacterial liquid was adsorbed by an adsorbent, and the adsorbed single bacterial agent was Mix according to the ratio of 1:1:1:0.8, keep the moisture within 30%, and the effective number of viable bacteria: 20 billion / g.

[0031] Among them, the adsorbent is mixed with organic powder accounting for 50%-90% by weight and inorganic powder accounting for 10%-50% by weight; wherein the organic powder is wheat bran, rice b...

Embodiment 2

[0034] Example 2 Preparation of New Multifunctional Compound Microbial Fertilizer

[0035] The ratio is: 25 parts of microbial agent, 8 parts of biochar, 12 parts of pyrethrum powder, 25 parts of urea, 15 parts of monoammonium phosphate, 11 parts of potassium chloride, 3 parts of biochemical fulvic acid, 1 part of EDTA chelated trace elements .

[0036] The specific preparation method is the same as in Example 1, and the nitrogen, phosphorus and potassium contents are respectively 13%, 7%, and 7%, and the total nutrient content is 27%.

Embodiment 3

[0037] Example 3 Fertilizer test

[0038] The fertilizer used in the comparative example: common compound fertilizer with a total nutrient content of 27%.

[0039] The fertilizer used in the embodiment: the fertilizer prepared in Examples 1 and 2 of the present invention.

[0040] The potato variety tested was "Holland Fifteen".

[0041] Test grouping: comparative example group, embodiment 1 group, embodiment 2 group.

[0042] The test was carried out in the modern agricultural demonstration garden in Shouguang City, Shandong Province. The test soil was moist brown loam. The soil in the 0-20cm soil layer before sowing contained 8.2g / kg of organic matter, 478mg / kg of total nitrogen, 46mg / kg of alkali-hydrolyzable nitrogen, and 9.9 of available phosphorus. mg / kg, available potassium 59mg / kg.

[0043] The comparative example group adopts 60kg common compound fertilizer (27% of total nutrient content) per mu, and embodiment 1 group and embodiment 2 groups adopt the fertilizer p...

Abstract

The invention discloses a novel multifunctional compound microbial fertilizer and belongs to the technical field of agricultural compound fertilizer. The novel multifunctional compound microbial fertilizer is prepared from the following raw materials: a microbial agent, biological carbon, pyrethrum powder, carbamide, monoammonium phosphate, potassium chloride, biochemical fulvic acid and EDTA chelated microelements. The novel multifunctional compound microbial fertilizer is capable of providing nutrients required for crops and is capable of excellently decreasing incidences of plant diseases and insect pests, so that the use of pesticide is reduced and the yield and the quality of the crops are improved.

Description

technical field [0001] The invention relates to a compound microbial fertilizer, which belongs to the technical field of agricultural compound fertilizers, in particular to a novel multifunctional compound microbial fertilizer. Background technique [0002] In my country, due to the long-term use of chemical fertilizers for many years, the shortage of organic fertilizers and the imbalance of various nutrients have caused the ecological environment of farmland, soil physical and chemical properties and soil microbial flora to be damaged to varying degrees, which has affected the safety of agricultural products to a certain extent. . At present, crop pest control is mainly to use chemical agents and toxic pesticides to mix and stir, and apply them to the soil or crops. Long-term use of a large amount of pesticides and fertilizers will easily cause pesticide resistance of pests, soil compaction, and damage to water sources, soil and crops. Pollution is caused and the quality of...
