Problems solved by technology

[0004] The purpose of the present invention is to provide a kind of seedling-raising substrate composition, seedling-raising substrate and its preparation method and the application in aspect rice seedling raising, this composition for seedling-raising substrate can be used for preparing rice seedling-raising substrate, and this rice seedling-raising substrate can greatly improve The cultivation quality of rice seedlings is mainly reflected in the fact that the cultivated rice seedlings have high biomass, root vitality index and fullness. In addition, the plant height and stem diameter are relatively ideal, which can solve the complicated preparation process of the current common rice seedling substrate. And the technical problem of rice seedling raising quality is low

preparation example Construction

[0022] The present invention provides a preparation method of a seedling-raising substrate, the preparation method comprising: according to weight percentage, 3%-20% of peat, 15%-30% of chaff ash, 5%-15% of vermiculite, clay 5%-15%, 5%-10% of fly ash, 20%-40% of straw-based edible fungus residue and 5%-25% of organic fertilizer are mixed, heat-treated and cooled to prepare.

[0023] In the above technical solution, the conditions of the heat treatment can be controlled within a wide range, but in order to improve the quality of the prepared seedling raising substrate, preferably, the conditions of the heat treatment are: the temperature is 150°C-170°C, the time It is 2h-4h.

[0024] In the above technical scheme, in order to further improve the seedling quality of the obtained seedling raising substrate, preferably, in terms of weight percentage, peat accounts for 5%-10%, chaff ash accounts for 19%-25%, and vermiculite accounts for 5%-15%. %, clay accounts for 5%-15%, fly ash...

preparation example 1

[0036] In terms of weight percentage, rice straw, corncobs, lime, sawdust, bran and urea are mixed and crushed in a weight ratio of 100:50-60:6-8:20-25:12-15:1.2-1.5 and then used as shiitake mushrooms The culture substrate of edible shiitake mushrooms is removed after they are matured to obtain the straw-based edible fungus residue;

[0037] Wherein, the cultivation conditions of the edible fungus are controlled as follows: the temperature is 28°C, the relative humidity is 80%, and the pH of the culture substrate is 5.1.

Embodiment 1

[0039] According to the percentage by weight, 10% of peat charcoal, 20% of chaff ash, 10% of vermiculite, 10% of clay, 10% of fly ash, 25% of straw-based edible fungus residue and 15% of organic fertilizer are mixed. After heat treatment at ℃ for 2 hours and natural cooling, the seedling-raising substrate was prepared, which was recorded as A1.

Abstract

The invention relates to the field of seedling raising, and discloses a composition for a seedling substrate, the seedling substrate, a preparation method thereof and the application in rice seedlingraising. The preparation method of the seedling substrate includes conducting mixing, heat treatment and cooling on the following materials by mass: 3%-20% of grass carbon, 15%-30% of rice husk ash, 5%-15% of vermiculite, 5%-15% of clay, 5%-10% of fly ash, 20%-40% of straw-based edible fungus residue and 5%-25% of organic fertilizer. The straw-based edible fungus residue is selected as the main raw material of the rice seedling substrate. The seedling substrate composed of the straw-based edible fungus residue and an organic fertilizer in specific ratio can effectively increase the biomass, the root activity, the fullness and the seedling index of seedlings. Moreover, the plant height and the stem diameter of the seedlings obtained are both ideal, and the growth rate is high.

Description

technical field [0001] The invention relates to the field of plant seedling-raising substrates, in particular to a composition for seedling-raising substrates, a seedling-raising substrate, a preparation method thereof, and an application in rice seedling raising. Background technique [0002] At present, my country's rice planting mostly adopts traditional field soil or nutrient soil to raise seedlings in seedling trays. This kind of seedling tray needs to dig a lot of upland soil, and add fertilizers, pesticides and acid adjustment treatment to configure it into nutrient soil, and then it can be used on the seedling bed of the seedling tray, which adds a lot of tedious work for rice farmers. The soil also needs to be topdressed with fertilizers in the middle and late stages of seedling cultivation, otherwise it will be difficult to cultivate strong seedlings. Moreover, it will also be infected by diseases and insect pests, the root system of rice seedlings is not develope...
