specific Embodiment approach 1

[0035] Specific embodiment 1: This embodiment is a rice seedling bed soil prepared by using microbial fermentation waste, which is composed of the following components by mass fraction: 20% to 30% of animal manure, 1‰ to 3‰ of microbial seed liquid, agricultural 20% to 40% of production waste, 15% to 35% of microbial fermentation waste, 5% to 20% of nutrients, 5% to 10% of bentonite, 5% to 20% of boric acid, and the balance is water.

specific Embodiment approach 2

[0036] Specific embodiment 2: The difference between this embodiment and specific embodiment 1 is that the animal manure is a mixture of one or both of herbivore manure and non-herbivore manure; when the animal manure is herbivore When the manure is a mixture of manure and non-herbivore manure, the mass of herbivore manure is 15% to 25% of the total mass of rice seedling bed soil. Others are the same as the first embodiment.

specific Embodiment approach 3

[0037] Specific embodiment three: the difference between this embodiment and specific embodiment one or two is: the described microbial strain liquid is made up of the following components by volume fraction: 30% Bacillus subtilis liquid, 30% Bacillus amyloliquefaciens liquid, 20% Bacillus polymyxa liquid, 10% Trichoderma viridans liquid and 10% Chaetomium globosa liquid; the culture medium of described Bacillus subtilis liquid is LB medium, and the concentration of Bacillus subtilis is 2 ×10 11 CFU / g; The culture medium of described Bacillus amyloliquefaciens liquid is LB culture medium, and the concentration of Bacillus amyloliquefaciens is 1 * 10 11 CFU / g; The culture medium of described bacillus polymyxa liquid is LB culture medium, and the concentration of bacillus polymyxa is 1 * 10 11 CFU / g; The substratum of described Trichoderma viride liquid is LB culture medium, and the concentration of Trichoderma viride is 2 * 10 9 CFU / g; The culture medium of described Chaetomi...

Abstract

The invention relates to a rice seedling-raising bed soil prepared by utilizing microbial fermentation waste and a preparation method thereof, relating to a rice seedling-raising bed soil and a preparation method thereof. The invention aims to solve the technical problems that the existing rice fermented seedling bed soil needs to be sterilized and acid-adjusted before sowing, the process is complex, the operability is low, the seedling emergence rate is low, the transportation of raw materials is difficult and the cost is high. The rice seedling bed soil of the present invention is composed of the following components: animal manure, microbial strain liquid, agricultural production waste, microbial fermentation waste, nutrient, bentonite and boric acid. The preparation method of the present invention is simple and low in cost, and the rice seedling emergence rate using the seedling bed soil is high, the organic matter content is high, and the nutrient content is rich, and a novel and environmentally friendly treatment method is provided for treating microbial fermentation waste and agricultural waste. And it can provide a suitable temperature for rice seedling raising in the colder northeast region in spring.

Description

technical field [0001] The invention relates to a rice seedling bed soil and a preparation method thereof. Background technique [0002] Rice is one of the main food crops in our country. In the seedling raising process, farmers often use field soil and nutrient soil to raise seedlings in trays. This dry raising method can obtain healthier seedlings in a short time, which is the key to stable rice production. At the end of the 1970s, it was popular in China to adjust the soil pH value to 5 for acid adjustment treatment, which can make the seedlings more robust. The preparation of nutrient soil and seedling trays requires farmers to dig a large amount of upland soil, apply chemical fertilizers and pesticides for treatment, and use sulfuric acid for acid adjustment treatment, which undoubtedly increases the cost and operation difficulty of farmers' rice planting. If it is not guaranteed, it is difficult to make the best effect of the dry breeding method. [0003] In recent y...
