Rice seedling substrate

Abstract

The invention discloses a rice seedling substrate which is prepared from 30%-35% by mass of rice husk, 25%-30% by mass of mushroom residue, 20%-25% by mass of vermiculite and 15%-20% by mass of an organic fertilizer by mixing, a preparation method of the rice seedling substrate comprises the following steps: 1) stacking the rice husk into piles, then adding an appropriate amount of water, and sprinkling zymocyte for fermentation at 35-40 DEG C for 24 hours; 2) evenly mixing the fermented rice husk in the step 1), the mushroom residue, the vermiculite and the organic fertilizer according to the above formula evenly, and then drying to obtain a mixture; and 3) crushing the mixture prepared by the step 2) to obtain the rice seedling substrate. By the way, the processing technique is simple, easy to control, and low in cost, the prepared rice seedling substrate which is rich in a variety of trace elements and active bacteria, and the transplanting survival rate of rice seedlings can be effectively improved.

Description

technical field [0001] The invention relates to the technical field of agricultural seedling raising and cultivation, in particular to a rice seedling raising substrate. Background technique [0002] my country is the country with the longest and richest history of rice cultivation, and China's rice cultivation has a history of at least 7,000 years. Rice production in China plays a pivotal role in China's grain production. The mechanization of rice transplanting is an aspect of rice industry development, and the key to machine transplanting is seedling raising. However, the existing seedling-raising substrate has a high production cost and lacks the nutrients needed by the rice seedlings, so the transplanting survival rate of the rice seedlings is low. Contents of the invention [0003] The technical problem mainly solved by the present invention is to provide a rice seedling raising substrate, which can solve the above-mentioned defects existing in the existing rice see...
