Seedling culture substrate sheet and preparation method thereof

Abstract

The invention provides a seedling culture substrate sheet which is prepared by the following steps that by taking livestock and poultry manure and corncob as main raw materials, micro-aerobic fermentation is conducted with an organic matter rapid decomposition agent to obtain a fermentation material, the fermentation material is mixed with a full-nutrient preparation, decomposition and aging are conducted, nutrients are stored in an organic state in an organic fertilizer, finally, the organic fertilizer, crushed agricultural organic waste, a disease prevention and weeding preparation and an adhesive are subjected to compression molding according to a certain mass ratio and dried to prepare the seedling culture substrate sheet. The full-nutrient preparation is added in the decomposition stage, nutrients in a micro-aerobic fermentation system can be gradually organized into organic-state nutrients to be stored in the organic fertilizer, and the total nutrient content of the organic fertilizer is greatly improved. The seedling culture substrate sheet has the effects of comprehensive nutrition, disease and pest prevention, weed prevention and seedling strengthening, and can remarkably improve the survival rate of seedling culture, and meanwhile, the organic nutrients and the disease prevention and weeding preparation can be slowly released in soil and absorbed by crop root systems.

Description

Technical field [0001] The present invention relates to a method for preparing a substrate sheet and breeding. Background technique [0002] Seedling Cultivation is the basis of high-yield rice, the saying goes, "good seedling Bacheng food," shows that key aspects of the nursery. For decades governments at all levels and relevant parts of the rice seedlings to spend on a lot of work, so that by the pit seedling rice seedlings developed into a small Gongpeng Raising Sparse is, but there is still the way to nursery soil preparation, hard hit bed , Chuangtu irrational allocation, drought does not dry nursery, Zhuangyangji use and irrational, weak seedlings, seedlings died frequent phenomenon, resulting in low germination rate, affecting rice cultivation. [0003] Seedling substrates prepared using a separate nursery is commonly used method, but many types are currently on the market for Seeding, but many can not meet the growth requirements of rice, most of the plant nutrients in a ...

AI Technical Summary

Problems solved by technology

Over the past decades, governments at all levels and relevant departments have spent a lot of effort on rice seedling raising, making rice seedling raising develop from pit-type seedling raising to the current small bow shed for dry and sparse vegetation. However, this seedling raising method still has difficulties in preparing soil and making beds. , Bed soil configuration is unreasonable, dry breeding is not dry, the use of seedling strengthening agent is unreasonable, etc. Weak seedlings and dead seedlings occur frequently, which eventually leads to low emergence rate and affects rice planting

[0003] Using a separately prepared seedling substrate for seedling cultivation is a commonly used method at present, but there are many types of seedling substrates on the market, but many of them are difficult to meet the growth requirements of rice. and the function of weed production, the phenomenon of weak seedlings and dead seedlings is more serious
