Embodiment 1

[0016] Embodiment 1: the preparation of microbial bacterial agent

[0017] The microorganisms were carried out using the selective medium Ashubei medium (mannitol 1%, potassium dihydrogen phosphate 0.02%, magnesium sulfate 0.02%, sodium chloride 0.02%, calcium sulfate 0.01%, calcium carbonate 0.5%, pH 7.0) Screening, measuring its nitrogen-fixing ability by acetylene reduction method, and selecting microorganisms with strong nitrogen-fixing ability.

[0018] Finally, the nitrogen-fixing bacterium Aeromonas salmonicida (Aeromonas salmonicida) was selected to construct the microbial agent. Aeromonas salmonicida (Aeromonas salmonicida) has a strong ability to fix nitrogen, decompose phosphorus, and decompose potassium. It can convert nitrogen in the air into nitrogen fertilizer that can be absorbed by plants, promote nitrogen cycle metabolism, and continuously provide plants with Nitrogen nutrition: It can convert insoluble phosphorus and potassium in the soil into available pho...

Embodiment 2

[0020] Embodiment 2: the preparation of microbial compound fertilizer

[0021] The microbial agent prepared in Example 1 and the chemical fertilizer are rationally proportioned according to the nutritional requirements of the crops in a ratio of 1:1 to make a microbial compound fertilizer. The components and ratios of fertilizers are: Potassium dihydrogen phosphate: Diammonium phosphate is 1:4.44. The developed microbial compound fertilizer can provide sufficient and reasonable nitrogen, phosphorus and potassium nutrients for crops, and the number of effective viable bacteria of probiotics can be kept at more than 100 million to 400 million / ml, which can not only improve crop yield and quality, but also It can also prevent soil pollution and improve soil.

Abstract

A microbial organic-inorganic compound fertilizer and a preparation method thereof. The invention, on the one hand, provides an application of aeromonas salmonicida in preparation of a microbial fertilizer and provides a microbial compound fertilizer on the other hand. The microbial compound fertilizer comprises an aeromonas salmonicida inoculant, humic acid and an inorganic fertilizer, wherein the quantity of live bacteria in the inoculant is 1-5 hundred million per gram and a mass ratio of the humic acid to the inorganic fertilizer is 5:5. The microbial compound fertilizer is rich in nutrition and can significantly improve quality and increase yield of cucumbers. Compared with a conventional compound fertilizer, the microbial compound fertilizer can increase the yield by 28% and the content of VC by 37% with an equal usage amount. In addition, the microbial compound fertilizer can promote an excellent ecological environment to form at rhizosphere and proliferation of beneficial microorganisms, thereby being beneficial to growth of crops. The microbial compound fertilizer can also increase a utilization rate of chemical fertilizers, can activate potential nutrients in soil and help the potential nutrients to release, improves resistance and immunity of crops and inhibits plant diseases and insect pests.

Description

technical field [0001] The invention belongs to the technical field of microbial fertilizers, and in particular relates to a microbial compound fertilizer and a preparation method thereof. Background technique [0002] The extensive use of chemical fertilizers has made food safety, ecological environment protection and sustainable use of resources the three major issues facing the development of agriculture in the world today, and is also a major issue related to the national economy and people's livelihood in our country. Microbial fertilizers have the characteristics of fertilizing soil fertility, improving the utilization rate of chemical fertilizers, reducing the content of nitrate nitrogen, heavy metals, and pesticides in agricultural products, improving the quality and safety of agricultural products, purifying and restoring the soil ecological environment, and improving the stress resistance of crops. The promotion and use of microbial fertilizers is an important supp...
