Problems solved by technology

However, there are certain defects and deficiencies in these three seedling pots: peat-type seedling pots have poor water absorption, low elasticity, incomplete nutrition, and high prices; straw-type seedling pots have incomplete nutrition, especially C / N ratio imbalance, easy to Burning seedlings; the mixed type only adds livestock and poultry manure on the basis of straw or wood chips, and the nutrient level is improved, but the nutrition is still unbalanced and incomplete without the input of nitrogen available to plants, and in some cases, livestock and poultry manure are used. Poultry manure may increase the risk of introducing weeds, insect eggs and animal and plant pathogenic microorganisms
Traditional bioinitiation is to coat bacteria on plant seeds, but this process requires a special binder, which is not conducive to seed respiration and affects germination and growth

Embodiment 1

[0054] Example 1: Construction of microbial composite functional flora

[0055] 本实施例中,选择Azospirillum spp.、Azobacter spp.、Bacillus spp.、Paenibacillus spp.、Massilia spp.、Stenotrophomonas spp.、Lysobacterspp中各一种菌株,具体为StenotrophomonasmaltophiliaMIM0101,Azotobacter chroococcumMIM0407,AzospirillumbrasilenseMIM0403,MassiliabrevitaleaMIM0205,BacillusmegateriumMIM0303, PaenibacilluspabuliMIM0312, LysobacterantibioticusMIM0212, see Table 1 for the performance test results of each bacteria. Each bacteria is cultured in R2A or MDM medium respectively through the first, second and third stages of amplified culture, then the bacterial cells and exopolysaccharides are collected by centrifugation, and mixed together in equal proportions according to the number of viable bacteria to form a composite functional flora sludge. The total number of viable bacteria in the sludge is about 10 10 CFU / g.

Embodiment 2

[0060] Embodiment 2: Seedling pot pressing and seedling raising

[0061] According to the weight ratio, dry and crush 75 parts of straw, 5 parts of sawdust, 5 parts of cow dung, 5 parts of peat, 5 parts of weathered coal, and 5 parts of campus black soil, pass through a 5-mesh sieve to remove large particles and impurities, and mix well , Steam sterilization at 80°C for 2 hours once a day, and extinguished 3 times. Store the sterilized biological matrix in a sterilized stainless steel bucket with a lid and set aside.

[0062] Under clean conditions, add 2L of sterile water to the composite functional flora in Example 1, resuspend, spray on the sterilized biological matrix with a sterile watering can, and stir while spraying. After spraying and stirring, knead by hand Agglomerates, not scattered (moisture content about 40%) can be pressed on the machine.

[0063] In a clean environment, use the TZB-60 pot making machine of Shandong Qufu Tianyang Machinery Factory to press the...

Embodiment 3

[0070] Embodiment 3: seedling pot bacterial classification ratio

[0071] StenotrophomonasmaltophiliaMIM0101, Azotobacter chroococcumMIM0407, AzospirillumbrasilenseMIM0403, Massiliabrevitalea MIM0205, Bacillus megateriumMIM0303, PaenibacilluspabuliMIM0312, Lysobacterantibioticus MIM0212 are mixed according to the ratio of other components in the flow process of Table 3.

[0072] When the tomato grows, record its plant height, and use the orthogonal analysis software to analyze that the 7 factors are extremely close, indicating that the selected 7 strains have similar effects on the experimental effect, but from the effect point of view, the ratio is 1:1: 1:1:1:1:1 or close to this ratio has better ability to promote tomato growth.

Abstract

The invention provides a degradable seedling growing pot with a function of promoting plant growth, a method for preparing the degradable seedling growing pot and application thereof. A seedling growing pot composition comprises mixed biological substrates and compound bacterial sludge. The mixed biological substrates comprise 50-80 parts of crop straw, 5-8 parts of sawdust, 5-10 parts of livestock and poultry manure, 2-5 parts of grass carbon, 2-5 parts of weathered coal and 3-6 parts of soil; the compound bacterial sludge comprises Azospirillum spp., Azobacter spp., Bacillus spp., Paenibacillus spp., Massilia spp., Stenotrophomonas spp. and Lysobacterspp. The degradable seedling growing pot, the method and the application have the advantages that the germination rates of plants can be increased by the degradable seedling growing pot prepared from the seedling growing pot composition, balanced nutrition required during growth can be supplied to seedlings, pathogenic microorganisms can be resisted, and accordingly the degradable seedling growing pot is favorable for strong seedlings.

Description

technical field [0001] The invention relates to a seedling cultivation container, which belongs to the technical field of microbial resource utilization and ecological agriculture, in particular to a seedling pot composition, a seedling pot and its preparation method, and the application of the seedling pot. Background technique [0002] Seedling pots are suitable for plants suitable for hole sowing. There have been many technical reports on the production and application of seedling pots at home and abroad, and certain application effects have been achieved. [0003] Existing and description From the perspective of the matrix material of the pressed degradable seedling pot, there are mainly peat type, straw type and mixed type. However, there are certain defects and deficiencies in these three seedling pots: peat-type seedling pots have poor water absorption, low elasticity, incomplete nutrition, and high prices; straw-type seedling pots have incomplete nutrition, especial...
