Embodiment 1

[0043] The liquid bacterial agent is composed of the following mass parts of the bacterial agent:

[0044]3 parts by mass of liquid Bacillus megaterium agent; 5 parts by mass of liquid Bacillus subtilis agent; 1 part by mass of liquid Streptomyces luteus agent; 3 parts by mass of liquid Bacillus licheniformis agent; 3 parts by mass of liquid Bacillus cereus agent; 3 parts by mass of agent; 3 parts by mass of liquid photosynthetic bacteria agent. The mixing ratio of liquid Bacillus megaterium agent, liquid Bacillus subtilis agent, liquid Streptomyces severus agent, liquid Bacillus licheniformis agent, liquid Bacillus cereus agent, liquid nitric acid agent, and liquid photosynthetic agent is: 3:5:1 :3:3:3:3.

[0045] Among them, the content of good bacteria in each liquid bacterial agent is greater than or equal to 200 million / ml.

[0046] The microbial liquid inoculant also includes trace elements, which are selected from B, Zn, Co, Fe, or a mixture of any three of them.

[...

Embodiment 2

[0061] The liquid bacterial agent consists of the following mass parts of the bacterial agent:

[0062] 2 mass parts of liquid Bacillus megaterium agent; 3 mass parts of liquid Bacillus subtilis agent; 1 mass part of liquid Streptomyces luteus agent; 2 mass parts of liquid Bacillus licheniformis agent; 2 mass parts of liquid Bacillus cereus agent; 2 parts by mass of agent; 1 part by mass of liquid photosynthetic bacteria agent. The mixing ratio of liquid Bacillus megaterium agent, liquid Bacillus subtilis agent, liquid Streptomyces severus agent, liquid Bacillus licheniformis agent, liquid Bacillus cereus agent, liquid nitric acid agent, and liquid photosynthetic agent is: 2:3:1 :3:3:3:1.

[0063] Among them, the content of good bacteria in each liquid bacterial agent is greater than or equal to 200 million / ml.

[0064] The microbial liquid inoculant also includes trace elements, which are selected from B, Zn, Co, Fe, or a mixture of any three of them.

[0065] Preparation:...

Embodiment 3

[0079] In the spring of 2019, a field test was carried out. Nine fields of 10m*10m with the same terrain and similar soil conditions were selected. They were divided into 3 groups, and each group was repeated 3 times. Tomato seedlings were planted in both groups. Both groups were fertilized normally, and the first group did not add Inoculum, the second group is applied to the composite microbial liquid inoculum of the present invention; measure the index of soil and tomato respectively after harvesting, and the data are as follows:

[0080] Table 1 Soil Index

[0081]

[0082] Table 2 Tomato Indicators

[0083]

[0084] It can be seen from the data in the above table that after the compound microbial liquid bacterial agent of the present invention is applied, the content of soil organic matter increases, the content of nitrogen, phosphorus and potassium increases, the pH is closer to neutral, and the soil properties are greatly improved. Tomato plant height and stem dia...

Abstract

The invention relates to the technical field of agricultural microorganisms, ecological planting and microbial agents, in particular to a composite microbial liquid agent for treating soil and a preparation method thereof. The composite microbial liquid agent comprises the following microbial inoculums in parts by mass: a liquid bacillus megaterium agent, a liquid bacillus subtilis agent, a liquidstreptomyces microflavus agent, a liquid bacillus licheniformis agent, a liquid bacillus cereus agent, a liquid nitric acid microbial inoculum and a liquid photosynthetic microbial inoculum. The composite microbial agent provided by the invention is large in effective viable count and comprehensive in function; various bacteria are coordinated and symbiotic with one another, so that the shelf life is prolonged.

Description

technical field [0001] The invention relates to the technical fields of agricultural microorganisms, ecological planting and microbial inoculum, in particular to a compound microbial liquid inoculum for soil treatment and a preparation method thereof. Background technique [0002] Due to the long-term excessive application of chemical fertilizers, a large number of soil compaction, acidification, and nutrient imbalance have occurred in my country's soil, and beneficial microorganisms in the soil have decreased sharply. Some elements such as nitrogen, phosphorus and potassium in the soil are lost, and some are consolidated in the soil and cannot be absorbed and utilized by crops. At the same time, the increase of pesticide residues is a serious threat to human health and safety. [0003] In recent years, the Ministry of Agriculture has proposed an action plan for zero growth of chemical fertilizers and pesticides and a plan for soil pollution prevention and control. In orde...
