Fermentation material used for solanaceae vegetable seedling raising substrate, preparation method of fermentation material, solanaceae vegetable seedling raising substrate and preparation method of substrate

Abstract

The invention discloses a fermentation material. The fermentation material comprises the following components: 150-300 parts of straws, 1-10 parts of bean dregs, 5-20 parts of urea, 0.1-4 parts of potassium dihydrogen phosphate, 50-200 parts of feces, and 1-2 parts of Gaoshi No.15 fungus strains (a new strain of Bjerkandera sp.), wherein the concentration of viable fungi is 1x10<9>cfu / g; and the fermentation material is utilized to prepare the solanaceae vegetable seedling raising substrate, and the substrate comprises the following components: 30-50% of the fermentation material, 15-20% of vermiculite, 15-25% of perlite, 15-20% of nutrient soil, and a compound fertilizer, wherein the usage amount of the fertilizer is 1-15% of the total mass of the fermentation material, the vermiculite, the perlite and the nutrient soil. According to the invention, the fermentation material containing the Gaoshi No.15 inoculant is added to the solanaceae vegetable seedling raising substrate to preventand treat the root diseases of seedlings, and the fermentation material cooperates with the nutrient soil and the compound fertilizer to promote healthy growth of the solanaceous vegetable seedlings;in the preparation process of the substrate, the fermentation material is heated and stirred for a plurality of times for further ripening and supplementing nutrients for the substrate, and the nature of the seedling raising substrate is more gentle so as not to burn the seedlings; and the components are more uniformly mixed to better provide nutrients and provide guarantee of prevention and control of the root diseases for the seedlings.

Description

technical field [0001] The invention relates to a seedling-raising substrate, in particular to a seedling-raising substrate and a preparation method thereof. Background technique [0002] Seedling raising is usually required before crop planting to improve the survival rate of crops and store energy for its subsequent growth. Seedling raising substrates are usually composed of carbon and nitrogen-rich nutrients, water retaining agents, wetting agents, disinfectants, fertilizers, etc. to meet the needs of seedling raising. Nutritional requirements during the period and preventing seedlings from being infected by microorganisms affect the survival rate and seed setting rate after transplanting. There are also many studies on seedling-raising substrates. For example, Chinese patent application CN106431576A discloses a rice machine-transplanted seedling-raising substrate, which consists of compost products, peat soil, and vermiculite. It is obtained after mixing the substances ...

Problems solved by technology

There are also many studies on seedling-raising substrates. For example, Chinese patent application CN106431576A discloses a rice machine-transplanted seedling-raising substrate, which consists of compost products, peat soil, and vermiculite. It is obtained after mixing the substances in a mass ratio of 7:2:1. This substrate simply provides nutrients, and has no other effects such as preventing and controlling root diseases of seedlings; Chinese patent application CN 105801286A discloses a rice tray-type seedling-raising substrate The composition includes carbonized straw, paddy field dry soil, compound fertilizer and soil disinfectant, wherein the weight ratio of carbonized straw is 60%, the weight ratio of paddy field dry soil is 39%, and the compound fertilizer N:P:K=15:15:15 The ratio is 0.05% to 0.5%, and the rest is soil disinfectant and plant growth regulator, and the ratio in the matrix is ​​0.05% to 0.5%. This matrix not only provides nutrients for the seedlings, but also can play a role in sterilization and disinfection. effect, but the latter effect is obtained by adding soil disinfectants, which is not environmentally friendly, and the effect is more severe and may have an impact on other components of the matrix

Moreover, the existing researches mainly focus on seedling-raising substrates for grain crops, and there are few studies on seedling-raising substrates for Solanaceae vegetables.
