Machine-transplanted rice seedling raising ground substance and production method thereof

Abstract

The invention relates to a rice seedling raising substrate and a production method thereof, in particular to a rice seedling raising substrate taking agricultural and forestal wastes as materials and mechanically transplanting rice seedlings, and a production method thereof. In the invention, organic wastes such as straws are taken as raw materials, fermented by various beneficial microorganisms, and prepared into an organic substrate with a fertilizer slow release and caking agent and a water retention agent. The rice seedling raising substrate has strong stress resistance and strong compatibility with mechanical rice transplanting technology, and makes the rice seedlings have good quality; and the technology of raising the rice seedlings by the substrate is simple, and has low cost and high success ratio.

Description

technical field [0001] The invention relates to a rice seedling-raising substrate and a production method thereof, in particular to a rice seedling-raising substrate for mechanized rice transplanting with agricultural and forestry waste as materials and a production method thereof. Background technique [0002] The existing seedling raising techniques of machine-transplanted rice include standardized plastic tray seedling raising technology matched with mechanical transplanting, open field double-film seedling raising cutting technology, calcium-plastic lining tray seedling raising technology, woven cloth seedling raising technology, etc. The above-mentioned seedling raising method still uses soil as the matrix material. Although the direct cost of raising seedlings with nutrient soil is relatively low, due to the high labor intensity of soil extraction, many labors for raising seedlings and raising seedlings, serious diseases, and complicated procedures, it is not convenient...

AI Technical Summary

Problems solved by technology

The above-mentioned seedling raising method still uses soil as the matrix material. Although the direct cost of raising seedlings with nutrient soil is relatively low, due to the high labor intensity of soil extraction, many labors for raising seedlings and raising seedlings, serious diseases, and complicated procedures, it is not convenient for standardization and standardized operation. Failure to master the technology often leads to seedling failure; at the same time, nutrient soil seedlings occupy a large area of ​​cultivated land, the weight of the seedling tray is large, and the operating machinery load is large and wears quickly, which limits the promotion of mechanized seedling transplanting technology.

[0003] In order to overcome the disadvantages of raising seedlings in nutrient soil, at present, crushed rice husks have been used directly as seedling raising substr...
