Soilless culture substrate and preparation method thereof

Abstract

The invention relates to a soilless culture substrate which is mainly applicable to seedling breeding of paddy rice and also applicable to seedling breeding of plants like flowers, grass and vegetables. The soilless culture substrate is characterized by containing any one selected from the group consisting of crushed rice hulls, furfural residues and xylitol residues, any one selected from the group consisting of brown coal powder, silicon calcium magnesium fertilizer and mushroom residues, dried cow dung, bentonite and insecticide-fertilizer. According to the invention, the soilless culture substrate contains a variety of micronutrient elements needed in growth of plants in a seedling stage and bactericides, has the characteristics of richness in nutrients, disease prevention, cold resistance, seedling strengthening, low cost, greenness, ecological environmental protection, convenient usage and the like, can create a good growing environment for the plants in a seedling stage, has good water retention performance, allows good consistency between a cover layer and a bottom layer to be obtained, can be directly used for bed paving, sowing, covering, thorough watering and mulching so as to breed standard seedlings, enables a high breeding rate of standard seedlings to be achieved, is beneficial for protection of ecological environment of farmlands and can realize recycling of agricultural wastes and standardized seedling breeding of plants; a preparation method for the substrate is scientific and reasonable, can be easily mastered and is convenient to operate.

Description

technical field [0001] The invention relates to the technical field of crop cultivation, and relates to a soilless cultivation substrate and a preparation method thereof, which are mainly used for raising rice seedlings, and can also be used for raising seedlings and cultivating plants such as flowers, grasses and vegetables. Background technique [0002] In recent years, the research on soilless seedling cultivation of rice has mostly used rice straw or straw as the main raw material of the matrix.

AI Technical Summary

Problems solved by technology

[0002] In recent years, most of the researches on soilless seedling cultivation of rice use rice straw or straw as the main raw material of the matrix. "and Chinese Invention Patent Publication No.: CN102010259A discloses "a straw substrate and its production method". The substrate has a relatively light specific gravity, and there are problems such as poor water retention capacity when seedlings are watered, straw and straw are easy to float, and seedlings are easy to float when transplanting seedlings.

At the same time, its manufacturing process is relatively complicated and the cost is high.

Chinese Invention Patent Publication No.: CN102177836A discloses "the method for raising rice seedlings without soil" although it solves the problems of seedlings floating, poor in quality and non-packed roots, but its manufacturing process is complicated, and the number of times of fertilization is increased during seedling raising, making its operation complicated. These are not in line with the simple and efficient concept of farmers' farming today, so it is not easy to popularize and use

Chinese Invention Patent Publication No.: CN1582622A discloses " the paddy rice soilless dry seedling raising method taking rice husk as substrate ", and it is to be the main raw material of substrate with pulverized rice husk, but this substrate water retention is poor, and the water consumption of raising seedling process is bigger, and The matrix of the covering layer is different from the substrate of the bottom layer, which is inconvenient for farmers to operate. At the same time, the pre-production process of the matrix is ​​also complicated
