Abstract
The present invention relates to a soilless seedling culture and pot-free transplantation method for cotton. A substrate layer is laid both on a seedling bed or a seedling culture tray in a greenhouse arched shed. Cotton seeds carefully selected are aired under the sun, and subsequently sown on the seedling bed or the seedling culture tray in the greenhouse arched shed. After the seeds are sown, the seeds are covered by the culture media of a proper thickness, water is also sprayed until the culture media are moistened, and films are subsequently covered. The culture media are periodically sprayed by nutrient liquid in the period of seedling culture. When cotton seedlings have 2 to 3 leaves, the films are uncovered, and the seedlings are strengthened for 2 to 3 days. When the cotton seedlings have 4 leaves, the seedlings can be pulled out. After the seedlings are pulled out, roots are dipped by life promoters. After the pot-free seedlings cultured in the steps are transplanted, water needs to be poured in time. Compared with traditional seedling culture and transplantation method with nutrient pots, the method of the present invention obviously reduces production cost, slightly shortens the rooting periods of the seedlings and has considerable yield of ginned cotton. Meanwhile, the application of the present invention largely improves the production efficiency of cotton seedling culture and transplantation.
