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 ...
