Problems solved by technology

[0005] At present, peat is an indispensable raw material in the substrate of vegetable seedlings at home and abroad, and the proportion in the substrate formula can account for about 30-50%. Peat generally comes from wetlands, and the reserves are limited. Excessive exploitation of peat will damage the wetland ecosystem. balance wreaks havoc
The uneven and non-renewable distribution of peat resources will greatly increase the cost of seedlings when used in seedling substrates

Embodiment 1

[0022] Embodiment 1 The growth-promoting effect of Bacillus amyloliquefaciens

[0023] 1. Activation and fermentation of Bacillus amyloliquefaciens

[0024] Transfer the Bacillus amyloliquefaciens WS-8 preserved on the slant to a 50mL Erlenmeyer flask for seed cultivation

[0025] After cultivating overnight, transfer to the fermentation medium substrate for culture after microscopic examination without bacteria.

[0026] The liquid fermentation medium formula of Bacillus amyloliquefaciens is: starch 0.7%, bean cake powder 1.4%, sucrose 0.2%, yeast extract 0.06%, peptone 0.05%, ammonium sulfate 0.13%, potassium dihydrogen phosphate 0.05%, magnesium sulfate 0.03% , manganese sulfate 0.01%, sodium chloride 0.02%, calcium carbonate 0.1%, pH7.3-7.5, the number of spores can reach 12 billion / ml after 48 hours of cultivation.

[0027] 2. Growth-promoting effect of Bacillus amyloliquefaciens

[0028] The test set three treatments: blank control (water irrigation), fermentation bro...

Embodiment 2

[0032] Embodiment 2 Preparation of biochar bacterial agent

[0033] The fermented Bacillus amyloliquefaciens fermentation liquid was adsorbed with straw-derived biochar at a mass addition ratio of 15%, 20% and 25%, respectively, and the number of Bacillus amyloliquefaciens in the biochar agent after adsorption was checked regularly. The results were obtained from It can be seen from Table 2 that the adsorption capacity of 20% is the best, and the number of live spores is kept the most. The number of live spores with a storage period of 6 months is relatively stable, and the adsorption capacity is not easy to infect miscellaneous bacteria.

[0034] Table 2 The shelf life of different addition ratios

[0035] .

Embodiment 3

[0036] Example 3 Determination of the volume ratio of organic fertilizer, biochar agent, and straw powder

[0037] Organic fertilizer (biogas residue + chicken manure, wherein the mass ratio of biogas residue: chicken manure = 1:2.5), biochar agent (absorption of Bacillus amyloliquefaciens is 20%) and straw powder are mixed according to different mass parts , it can be seen from Table 3 that the mass ratio of treatment 3, treatment 4 and treatment 5 can effectively improve the germination index and strong seedling index of cucumber, and the difference between the treatments is not significant. Based on the consideration of input cost, organic fertilizer, The optimal mass ratio of biochar agent and straw powder is 7:40:2, which can effectively improve the germination index and strong seedling index of cucumber.

Abstract

The invention discloses a cucumber seedling substrate. The cucumber seedling substrate is prepared from, by weight, 1.5-2.5 parts of biogas dregs, 4-6 parts of chicken manure, 35-45 parts of biological carbon inoculant, 1.5-2.5 parts of straw powder and 1 part of perlite. The preparing method comprises the steps of taking components by weight part and mixing evenly the components through a roller. According to the cucumber seedling substrate, no grass carbon is adopted at all, therefore, the problems that grass carbon is expensive and is non-renewable in resource are solved, meanwhile the problem that large biogas residues pollute environment and an environment pollution problem brought by random stacking and arbitrary firing of corn and wheat straw are solved, and the cucumber seedling substrate can effectively maintain living and life environment of people, is beneficial to cycle development of agricultural economy, and has remarkable economic and social benefits. The use of the cucumber seedling substrate can effectively promote the growth of cucumber root systems, meanwhile is beneficial to reducing occurrence of soil-borne diseases, reduces the use of chemical agents, and facilitates the production of green vegetables.

Description

technical field [0001] The invention belongs to the technical field of soilless cultivation, and in particular relates to a substrate for cultivating cucumber seedlings and a preparation method thereof. Background technique [0002] With the rapid development of the facility vegetable industry, large-scale, intensive and professional seedling bases are developing rapidly. Whether the vegetable seedlings are healthy or not is not only related to the health status, disease resistance, product quality, yield and income of the growers after planting. , and can affect the healthy development of the entire vegetable industry, so the seedling substrate is a necessary choice for the growth and development of seedlings, and its reasonable choice becomes the premise to ensure the healthy development of the vegetable industry. [0003] Biogas residue is a residue of biogas, which contains rich nutrients such as N, P, K, organic matter, humic acid, biologically active substances, trace ...
