Non-ventilation simple management method for cotton seedling cultivation bed

Abstract

The invention discloses a ventilation-free simple management method for a seedling bed for raising cotton seedlings and belongs to a technique for crop cultivation management. The method comprises the following steps: drying a seedling bed used for raising cotton seedling in a micro pot or in a common nutrition pot when cotyledons of a cotton seedling fully expand; mixing a protective fungicide of Cocide or Kocide 2000 and 15 percent Paclobutrazol in the same proportions and diluting the mixture 1 / 250, or mixing a systemic fungicide of 60 percent Carbendazim, Procymidone and 15 percent Paclobutrazol and diluting the mixture 1 / 170; spraying the diluted mixture on the seedling till the cotyledons and leaves of the seedling are fully covered with the medicine; drying the seeding for two days and closing the seedling bed; removing a plastic film and hardening seedlings when the cotton seedling grows 2 to 3 leaves and one core for 3 to 5 days; and then transplanting the cotton seedling. The management method for the seedling bed ensures high temperature of the seedling bed, rapid growth of cotton seedling, and seedling raising time shorten 5 to 7 days compared with the prior ventilation plastic film removal-free management method.

Description

1. Technical field [0001] The invention discloses a ventilation-free and simplified management method for cotton seedling-raising seedbeds, which belongs to crop cultivation management technology and is specially used for cotton seedbed management. 2. Background technology [0002] Cotton nutrient pot seedling transplanting is a major innovation of cotton cultivation technology in my country. Since the 1950s, it has been continuously improved and perfected, and has developed into the main planting method in the Yangtze River Basin and the Yellow River Basin. However, due to the large amount of labor and high labor intensity for pot making, seedbed management, and transplanting, this technology has become a factor restricting the stable development of cotton production under the current situation of a large number of labor transfers. Therefore, the study of simplified cotton cultivation techniques to simplify production management and reduce production costs has become a hot ...
