Rice mud open-air sprout cultivation method

Abstract

A method for culturing the rice seedlings transplanted by throwing them in paddy field features that the traditional wet culture method is used as its technological platform, the rice seedlings are cultured in sludge instead of nutritive soil, and said culturing sludge is contained in plastic tray without covering plastic film.

Description

technical field [0001] The invention relates to a rice seedling raising method, in particular to a muddy open-air seedling raising method on the original bed of rice throwing seedlings. Background technique [0002] Rice seedling throwing cultivation technology began in the 1960s and was introduced into my country in the 1970s. It is generally welcomed by farmers because it saves labor and labor, is simpler to operate, has high yield and is stable compared with traditional methods. It has changed the traditional habit of pulling and transplanting rice seedlings that has been followed for thousands of years by farmers who "face to the loess and back to the sky", and is a major reform of rice cultivation technology. Seedling-throwing rice cultivation technology is listed as a key technology promotion project by the country. In recent years, the seedling-throwing technology with "plastic floppy disk nutrient soil plus film covering seedling raising" (abbreviated as nutrient soi...

AI Technical Summary

Problems solved by technology

[0003] 1. It is inconvenient to prepare nutrient soil. The proportion of fertilizer to be added should be calculated according to the local soil conditions. Too much fertilizer will easily burn the seedlings, and too little fertilizer will easily cause yellowed seedlings.

Poor preparation of nutrient soil directly affects the quality of seedlings

[0004] 2. The labor investment is relatively large, and the bed surface must be made into mud before sowing. The water source in dry land is inconvenient, and it is necessary to manually carry water for land preparation, and dry land preparation is more laborious than water preparation.

[0005] 3. Lay film after sowing, high temperature and high humidity seedlings are prone to blight, if the green film is not removed in time, it is easy to burn the seedlings, and it is inconvenient to manage the fertilizer and water in the seedling field after the film is spread

[0006] 4. The overall technical steps are cumbersome. It is necessary to prepare nutrient soil, pick water, spread film, eliminate it, and prevent and control blight; the technology is complex, the preparation of nutrient soil, the use of chemical agents, the operation and timing of film laying and peeling off

[0007] More steps mean more links will affect the safety of rice seedlings
