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

Embodiment 1

[0044] 1.1 Preparation of carbonized straw

[0045] The rice husk was calcined at 200° C. for 180 min to obtain carbonized straw.

[0046] 1.2 Configure rice seedling bed soil

[0047] Take 250 kg of paddy field soil, 250 kg of a mixture of carbonized straw and rice husk, wherein the volume of carbonized straw and rice husk is equal, mix to obtain 500 kg of rice seedling bed soil mixed with carbonized straw and rice husk, and then add urea 0.16 kg, hydrogen phosphate Diammonium 0.4kg, potassium sulfate 0.4kg, 20g carbendazim (purity quantity) and 20g thiram (purity quantity), mix well.

[0048] 1.3 Configure pH buffer solution (solution A)

[0049] Weigh Na 2 HPO 4 Added into water with pH=7.0, fully dissolved to obtain 0.2mol / L Na 2 HPO 4 solution. Weigh citric acid and add it into water with pH=7.0, fully dissolve to obtain 0.1 mol / L citric acid solution. According to Na 2 HPO 4 The volume ratio of the solution to the citric acid solution is 51.5:48.5, and the acid s...

Embodiment 2

[0070] The difference between this example and Example 1 is that the seedling bed soil does not contain any carbonized straw, and the amount of rice husk is 250m 3 .

Embodiment 3

[0072] The difference between this example and Example 1 is that the seedling bed soil does not contain any rice husks, and the amount of carbonized straw is 250m 3 .

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.
