Protected cultivation method for green asparagus in warm regions

Abstract

The invention discloses a protected cultivation method for green asparagus in warm regions. According to the characteristics of the biological characteristics of the asparagus, the characteristics of generation and development of diseases and insect pests of the green asparagus in the warm regions and the characteristics of protected cultivation in the warm regions, soil conditions, cultivation facilities, seedling growing, planting, field management and disease and insect pest comprehensive control are modeled, and the technical system of comprehensively controlling regulation cultivation and diseases and insect pests of the green asparagus in the warm regions is provided. According to the protected cultivation method, the spring green asparagus can be harvested in winter, the winter sleep period of the green asparagus can be shortened, the harvesting period of the green asparagus can be prolonged, the yield and the quality of the green asparagus can be effectively improved, generation and development of the diseases and the insect pests of the green asparagus in the warm regions can be effectively controlled, the pesticide use time number is remarkably decreased, the pesticide use amount is remarkably reduced, and the protected cultivation method is of great significance on improving the economic value of the green asparagus and protecting the environment.
