Soil-less seedling growing and pot-free transplanting method for cotton

Abstract

The present invention is soil-less seedling growing and pot-free transplanting method for cotton. The soil-less seedling growing process incldues spreading substrate on seedbed, seeding sunned cotton, covering cotton seed with the substrate, spraying water to the substrate, covering with film, spraying nutritive liquid regularly, uncovering the film to strengthen the seedling for 2-3 days after the cotton seedling grows to have 2-3 leaves, taking seedling after cotton seedling grows to have 4 leaves and dipping the roots of seedling with promoter before the seeding is transplanted. Compared with traditional seedling culturing container process, the present invention has obviously lowered production cost and raised production efficiency.

Description

technical field

[0001] The invention belongs to cotton seedling raising and transplanting methods, in particular to a soilless cotton seedling raising and transplanting method. Background technique

[0002] Nutritive pot seedling transplanting technology has effectively solved a series of major key technical problems affecting cotton yield and quality, such as cotton one-sow full seedlings and wheat-cotton interplanting cotton late maturity, etc. The cotton area has been popularized and applied rapidly, and the cotton in major cotton-producing provinces such as Henan, Shandong, Jiangsu, and Hubei has rapidly developed from a single-cooking system to a double-cooking system for wheat and cotton, which has played an important role in improving cotton quality and promoting both grain and cotton harvests. . Up to now, the national application area is still more than 30 million mu, accounting for more than one-third of the total planting area. For example, about 6 million mu of ...
