Rice soilless and droughty seedling cultivation method using rice husks as substrate

Abstract

A soilless culture method with rice husk as matrix for rice seedlings includes such steps as breaking rice husk, immersing in water, stirring, spreading, applying water, covering by film, holding water content, and applying fertilizer. Its advantages are high yield and high quality of rice.

Description

Technical field: [0001] The invention relates to a rice seedling raising method. Background technique: [0002] The existing soil seedling raising method has the problems of low labor efficiency and high production cost. It is found through literature search that the existing seedling raising method involving rice has "rice husk soilless seedling raising technology" ("Modern Agriculture", No. 08, 2002 , Authors: Liu Yankun, Zhang Guojun, Zhang Susheng, Wang Jian), which involves "Using biotechnology to ferment rice husks to produce decomposed organic fertilizers, by matching with crushed rice husks of different particle sizes, artificially simulating soil using rice husks for soilless seedling cultivation technology”, which has the disadvantages of complicated procedures and high cost; another “research on rice seedling cultivation technology without soil substrate” ("Reclamation and Rice Planting" 2001 (5)-14-15, authors Zhang Weiquan, Yang Aidong, etc.), It involves "usin...

AI Technical Summary

Problems solved by technology

The method for raising seedlings of the present invention solves the problems of destroying ecology and environmental pollution in raising seedlings with soil, solves the problem of difficulty in taking soil for conventional dry seedling raising, solves the problem of mechanical watering, and solves the problem that herbicides for seedbeds exist in seedlings For the problem of pesticide residues, since no chemical agents are used to kill weeds in the seedbed during the seedling raising process, the process is saved, time and cost are saved, and work efficiency is improved; Fast, strong tillering ability, high yield and good rice quality. Experiments have proved that the seedlings bred by the method of the present invention can increase the yield by 5.7% compared with the conventional method of raising seedlings with soil; the method of raising seedlings of the present invention improves labor efficiency and reduces production costs. , is conducive to the development of green food, is an environmental protection project, an ecological project, a green project, and is conducive to popularization and application
