Problems solved by technology

[0003] After the above-mentioned common fertilizers are applied to the soil, they will have the expected promotion effect on the growth of crops. However, after long-term use of fertilizers in the soil, the excess inorganic elements remaining in the soil may lead to salinization or compaction of the soil The phenomenon of salinization or compaction of the soil is very unfavorable to the growth of crops. Therefore, the soil moisture of the soil after long-term fertilization will be seriously degraded
[0004] On this basis, CN201310021433.0 proposes a nanometer soil moisture restoration material and its production method, aiming at improving the soil environment after fertilization, but it is only used as a soil restoration material, and it still needs to be planted with a large amount of chemical fertilizers. At the same time, its yield-increasing effect is limited, it is not specific, and it cannot perform biological nitrogen fixation and slow-release fertility.

Embodiment 1

[0020] The special fertilizer for nano-organic rice of the present invention includes: 10% of biological flora raw materials, 2% of metal complexes, 15% of nanometer soil moisture materials, and 73% of fillers; the biological flora raw materials include: purple bacteria, blue Chromobacterium, Streptomyces and Nocardia bacteria groups and different culture materials for culturing the above bacteria groups; The metal complex and the nano soil moisture material carry out a cross-linking reaction to form a complex soil moisture material; The fillers include: humic acid, phosphate, biological fermentation organic matter, and water-absorbing materials.

[0021] Preferably, the culture materials of the biological flora raw materials include: purple bacteria culture material 20%, blue bacteria culture material 20%, Streptomyces and Nocardia culture material 60%; the above three culture materials The bacterial index of the corresponding microorganisms cultured in all reached 40 billion...

Embodiment 2

[0025] A processing method of a special fertilizer for nano-organic rice, which comprises the following steps:

[0026] S1. Propagate and cultivate purple bacteria, blue bacteria, Streptomyces and Nocardia in different culture materials respectively, so that the bacterial index of each microorganism reaches 40 billion / kg, and then mix evenly to form biological flora raw materials. The proportion of bacteria involved in the three parts of purple bacteria, blue bacteria, Streptomyces and Nocardia in the flora raw material is 1:1:3;

[0027] S2. The metal complex formed by mixing and reacting 2 parts of zinc sulfate, 1 part of magnesium sulfate, 2 parts of copper sulfate, 15 parts of EDTA, and 190 parts of water, and then crossed 1 part of metal complex with 7.5 parts of nanometer soil moisture material. Combined reaction to form complex soil moisture material;

[0028] S3. Mix 10% of the biological flora raw material, 17% of the complex soil moisture material, and 73% of the fi...

Embodiment 3

[0035] In order to compare the application fertilizer efficiency of the nano-organic rice special fertilizer of the present invention on rice with commonly used organic fertilizers, we carried out rice application of nano-organic rice special fertilizer in Gaolongyang rice field, Wenchang East Road, Hainan from February to June 2020. Fertilizer Efficiency Test:

[0036] 1. Time and place

[0037] 1.1 Test period: February 2020 to June 2020.

Abstract

The invention discloses a nano organic fertilizer special for rice, which has the advantages of water retention, fertilizer retention, slow release, reduction of chemical fertilizer consumption, increase of rice yield, improvement of rice quality, improvement of soil aggregate structure and microbial environment, increase of soil organic matter content, promotion of rice root growth, increase of leaf area and chlorophyll content, and improvement of photosynthesis after application. The compound fertilizer has the advantages of being simple in preparation process, good in biological activity, capable of fixing nitrogen and digesting nitrate ions, sulfur ions and heavy metal ions in soil, capable of resisting rice sheath blight disease, bacterial leaf blight and the like, and remarkable in advantage compared with existing chemical fertilizer and biological fertilizer products.

Description

technical field [0001] The invention relates to the field of microbial fertilizers, in particular to a special fertilizer for nanometer organic rice. Background technique [0002] At present, in agricultural planting, in order to increase the yield of crops, people will take the method of applying fertilizer to the soil to increase the nutrients of the soil and better be absorbed by the crops. Common fertilizers include chemical fertilizers, farmyard manures and microbial fertilizers; chemical fertilizers are also called inorganic fertilizers, which can be divided into many types according to their different components, such as nitrogen fertilizers, phosphate fertilizers, potash fertilizers, etc. Different types of fertilizers have different effects on the growth of crops. However, its common role is to provide macronutrients for the growth of crops; farmyard manure, also known as organic fertilizer, can supply nutrients and active substances to crops. In the process of usin...
