Rice seedling growth method

Abstract

The invention provides a rice seedling growth method, comprising the steps of (1) preparing a growth medium, made from, by weight, 80-90 parts of straws, 10-20 parts of straw char, 5-15 parts of animal excrement, 5-15 parts of slag, 0.04-0.05 part of a fermenting bacterium, and 0.8-72 parts of water; (2) dividing the growth medium into two parts, mixing one part with charcoal-base fertilizer, using the mixture as covering earth, and using the other part as culture earth; seeding in the culture earth, covering the surface of seeds with the covering earth, and spraying an aqueous solution of wood vinegar; (3) after the seeds grow seedlings, scattering charcoal-based fertilizer, and spraying the aqueous solution of wood vinegar. The soilless culture medium herein causes less environmental pollution due to straw incineration, the problems are effectively solved, such as difficulty in collecting seedling growth soil from saline-alkaline soil, shortage of bed soil resources and high growth cost, and a new way is provided for the development of seedling growth techniques to harmless, low-cost and low-carbon trend.

Description

technical field

[0001] The invention belongs to the technical field of dry seedling raising, and in particular relates to a method for dry seedling raising of rice in saline-alkaline land. Background technique

[0002] There are large areas of saline-alkali land distributed in my country. In recent years, the area of ​​rice planting in saline-alkali land has been expanding, and problems such as low rice yield, poor planting economic benefits, and lack of efficient cultivation techniques have become increasingly prominent. Among them, the difficulty of raising rice seedlings in saline-alkali land has become the primary problem to be solved urgently. The traditional dry seedling raising technology is simple and easy to implement, but in saline-alkali areas, because the saline-alkali in the soil is not conducive to the growth of seedlings, it is difficult to collect the seedling bed soil, the pH of the bed soil is not easy to control, and it is easy to cause damage to soil and ...

Embodiment 1

[0043] Present embodiment provides a kind of rice seedling raising method, comprises the steps:

[0044] (1) prepare seedling raising substrate, the steps are as follows:

[0045] S1. Weigh 75kg of corn stalks, 10kg of rice stalks, 10kg of chicken manure and 10kg of high-phosphorus slag, and crush the straw, chicken manure and high-phosphorus slag into 50 meshes respectively;

[0046] S2. Sprinkle 50kg of water evenly into the crushed straw, and then add 8×10 8 CFU / g of Candida 0.0135kg and a bacterial content of 20×10 8 CFU / g plant lactic acid bacteria 0.0315kg, stir evenly, stack, cover with film, heat preservation and fermentation at 30°C, turn the pile once every time the stacking temperature reaches 50°C, and obtain straw decomposed clinker after 12 days of fermentation;

[0047] S3. Stir and mix the straw decomposed clinker with 15 kg of straw charcoal, chicken manure, and high-phosphorus slag evenly, the stirring speed is 20 r / min, and the stirring time is 4 minutes, ...
