Rice seedling raising bed soil, application and seedling raising method

Abstract

The invention discloses rice seedling raising bed soil, application and a seedling raising method. The rice seedling bed soil provided by the invention comprises rice field soil, simple substance fertilizer, bactericide and carbonized straw and / or rice husks, is simple in component, does not need to be decomposed, and is matched with the following seedling raising method of firstly, putting rice bud seeds into the rice seedling bed soil, adjusting the pH value of the rice seedling bed soil to 4.5-5.5 by adopting a pH buffering agent, in the increasing period of the leaf age of rice seedlings,additionally spraying a nutrient solution, specifically, when the leaf age of the rice seedlings reaches 1.5-2.0 leaves, spraying simple substance nitrogen fertilizer and simple substance potassium fertilizer; when the leaf age of the rice seedlings reaches 2.0-3.5 leaves, spraying inter-seedling bactericide and the simple substance nitrogen fertilizer; after the leaf age of the rice seedlings reaches 3.5-4.0 leaves, hardening the seedlings and spraying the simple substance nitrogen fertilizer and an insect-resist agent; and transplanting after seedling hardening. According to the method, theseedling quality can be ensured, the production cost is saved, the production requirement is met, and rapid seedling emergence can be realized.

Description

technical field [0001] The invention relates to the field of agricultural technology, in particular to a rice seedling raising bed soil, its application and a seedling raising method. Background technique [0002] At present, the research on the substrate of rice seedlings is extensive, and its components are mostly made of straw, coconut bran, livestock manure, vermiculite, perlite, etc., but there are limitations. First, the materials need to be fully decomposed, and materials that are not fully decomposed cannot be used. For the configuration of the seedbed soil, the phenomenon of dead seedlings frequently occurs due to the period; second, the cost is high, and it is necessary to add a decomposing agent during the decomposing process. The more mature decomposing agent is expensive, although it can achieve a better decomposing effect , but the production cost increases; third, it is not easy to obtain materials, taking vermiculite as an example, it is a kind of natural ino...

Problems solved by technology

[0002] At present, the research on the substrate of rice seedlings is extensive, and its components are mostly made of straw, coconut bran, livestock manure, vermiculite, perlite, etc., but there are limitations. First, the materials need to be fully decomposed, and materials that are not fully decomposed cannot be used. For the configuration of the seedbed soil, the phenomenon of dead seedlings frequently occurs due to the period; second, the cost is high, and it is necessary to add a decomposing agent during the decomposing process. The more mature decomposing agent is expensive, although it can achieve a better decomposing effect , but the production cost increases; third, it is not easy to obtain materials, taking vermiculite as an example, it is a kind of natural inorganic minerals, only 6 countries in the world produce it, and the materials are not easy to obtain; fourth, the existing rice seedlings are acid-adjusted, Most of them are sulfuric acid, which is a high-risk chemical, poisonous and harmful.

Fifth, the water acidified by sulfuric acid is used to pour the seedbed, which is very easy to burn the seedlings, causing the leaves to dry up and bring certain damage to the production

[0003] The current rice seedling bed soil configuration steps are complicated, it is extremely difficult to master in production, the operability is not strong, and the cost is high
