specific Embodiment approach 1

[0030] Specific embodiment one: In this embodiment, a kind of rice husk charcoal-based bacterial fertilizer, the bacterial fertilizer consists of 50-70% rice husk biochar, 9-11% beneficial microbial compound bacterial agent, 9-11% Binder and the rest of the nutritional elements;

[0031] The nutrient elements are composed of 20-40% calcium superphosphate or diammonium hydrogen phosphate, 20-33% carbonyl and the remainder potassium chloride by mass percentage;

[0032] The beneficial microbial composite bacterial agent is a mixture of two or more of the bacillus agent, nitrogen-fixing bacteria agent, phosphate-dissolving bacteria agent, potassium-dissolving bacteria agent, actinomycetes agent and photosynthetic bacteria agent mixed in any proportion.

[0033] This embodiment has the following beneficial effects:

[0034] 1. This embodiment aims at the problems of poor adaptability and low activity after the application of microorganisms, and proposes to adjust the porosity and...

specific Embodiment approach 2

[0042] Embodiment 2: This embodiment differs from Embodiment 1 in that: the binder is a mixture of bentonite and vegetable starch or both in any proportion. Other steps and parameters are the same as those in the first embodiment.

specific Embodiment approach 3

[0043] Specific embodiment three: the preparation method of rice husk charcoal-based bacterial fertilizer in this embodiment is carried out according to the following steps:

[0044] 1. Processing of rice husk biochar

[0045] After the rice husk is dry-distilled and gasified to obtain rice husk charcoal, then the rice husk charcoal is placed in a pulverizer to be pulverized into 0.1-0.5mm rice husk charcoal fine powder, and finally the rice husk charcoal fine powder is naturally settled in a closed tank for 15 ~25 minutes, the obtained rice husk biochar;

[0046] 2. Pretreatment of nutrient elements

[0047] Weigh 20-40% of calcium superphosphate or diammonium hydrogen phosphate, 20-33% of carbonyl and the rest of potassium chloride as raw materials according to mass percentage, and then dissolve the weighed raw materials in water to obtain the raw material concentration 90~110g / L nutrient solution;

[0048] 3. Bacteria compound

[0049] Two or more of the bacillus agent,...

Abstract

The invention relates to a microbial fertilizer and a preparation method and application thereof, in particular to a rice hull carbon-based microbial fertilizer and a preparation method and application thereof, and aims at solving the problems that after an existing microbial fertilizer is applied, due to the low microbial content, the poor microbial activity and the weak microbial competitiveness, the yield of crops is low. The rice hull carbon-based microbial fertilizer is prepared from 50-70% of rice hull charcoal, 9-11% of beneficial microorganism complex microbial inoculant, 9-11% of binder and the balance nutrient elements. The preparation method includes the steps of 1, processing of the rice hull charcoal; 2, preprocessing of the nutritive elements; 3, fungicide compounding; 4, preparation of the rice hull carbon-based microbial fertilizer. According to the application, the rice hull carbon-based microbial fertilizer is added into chemical fertilizer according to the additive amount of 3%-5% by mass for being used. The rice hull carbon-based microbial fertilizer provides a perfect habitat for probiotics, crop growth can be stimulated, metabolism of the crops can be adjusted, the yield is increased obviously, the fertilizer efficiency is durable, and the per mu yield of the crops is increased by 8%-23%. The preparation method and application are suitable for the rice hull carbon-based microbial fertilizer.

Description

technical field [0001] The invention relates to a bacterial fertilizer and its preparation method and application. Background technique [0002] As an important by-product of rice processing, rice husk contains a large amount of organic matter, a certain amount of nutrients such as silicon, nitrogen, phosphorus, potassium and trace elements, and is one of the important organic fertilizer sources for agricultural production. Rice husk charcoal has great Good gap and supporting effect provide an ideal place for the activities of microorganisms. my country is a large agricultural country, with 2 billion mu of arable land and an annual demand of 150 million tons of chemical fertilizers. It is the world's largest importer of chemical fertilizers. Even so, the amount of chemical fertilizers still cannot meet the needs of agricultural development. The key problem is that the utilization rate of chemical fertilizers is too low. According to surveys, the utilization rate of chemica...
