specific Embodiment approach 1

[0016] Specific embodiment one: the production method of paddy rice dry-raised strong seedling biological matrix in the present embodiment is carried out according to the following steps:

[0017] Step 1. Mix 100kg / ton of rice husk (biological matrix) with 900kg / ton of cow dung, add 2kg of mixed bacterial solution, stack it outdoors at 25°C for 25 days, then add 5kg / ton of lactic acid bacteria solution, mix well and then stack 10 days; get organic matter. Wherein, in the step 1, the mixed bacterial liquid is formed by mixing the Bacillus subtilis bacterial liquid and the Bacillus megaterium bacterial liquid, the spores of the Bacillus subtilis in the mixed bacterial liquid are 1 billion / mL, and the spores of the Bacillus megaterium are 1 billion / mL mL;

[0018] The number of bacteria in the lactic acid bacteria liquid in step 1 is 3 billion / mL.

[0019] Step 2, add 48kg / ton of pure nitrogen, 30kg / ton of pure phosphorus, 17kg / ton of pure potassium and 5kg / ton of pure zinc to ...

Abstract

The invention relates to a production method of rice seedling dry raising and strengthening biological medium and application thereof and belongs to the technical field of rice seedling dry raising. The invention aims at solving the technical problems that a large area of high-quality farmland is destroyed for a reason that a great amount of seedling raising bed soil is grabbed from a farmland during rice seedling dry raising; environmental pollution is caused for a reason that chemical bactericide, herbicide and industrial concentrated sulfuric acid are greatly applied during rice seedling raising. The method provided by the invention comprises the following steps: 1. mixing rice husks with cow dung, adding mixed bacteria liquid, performing outdoor stacking and composting, then adding lactic acid bacteria liquid, performing uniform mixing, and then stacking for 7 to 10 days; 2. adding pure nitrogen, pure phosphorus, pure potassium and pure zinc, and then performing uniform mixing; 3. adding a binding agent, compressing into thin sheet and drying. The application of the rice seedling dry raising and strengthening biological medium comprises the steps of flatly laying each piece of biological medium in a rice seedling raising tray, thoroughly watering the biological medium, then uniformly spreading germinated rice seeds and putting the tray in a plastic greenhouse for rice seedling raising. The biological medium can achieve the same rice seedling strengthening effect as the existing rice seedling strengthening agent, and is safe to the environment and pollution-free.

Description

technical field [0001] The invention belongs to the technical field of rice dry-raising; in particular, it relates to a production method and application of a biological substrate for dry-raising rice seedlings. Background technique [0002] Since the introduction of rice dry-raised sparse planting technology in the 1980s, it has been widely promoted and applied nationwide. The core of rice dry-raised sparsely planted technology is to promote the early growth of tillers through dry-raised rice seedlings during the rice seedling field stage. Rapid growth, so as to realize the optimization of the relationship between individuals and groups in the process of rice growth and development in the field stage, and realize high yield and high quality of rice. As we all know, the seedling-strengthening agents commonly used in rice seedling fields are composed of N, P, K macronutrients, Zn, Cu, Mg, B and other medium and trace mineral nutrients, acid regulators and chemical fungicides....
