Two-section type high-yield cultivation method for greenhouse asparagus

Abstract

The invention belongs to the field of vegetable farming and particularly provides a two-section type high-yield cultivation method for greenhouse asparagus. The method comprises the steps of cultivating and breeding biennial and triennial asparagus stools in the open field, preparing a field planting house, manufacturing standard ridges, preparing and applying planting nutrient soil, digging roots, transplanting the roots, planting the roots in a field mode, carrying out management after field planting and carrying out management all year round. According to the method, two-section type close planting cultivation is adopted, the investment is small, the yield is high, and the ecological environmental protection is achieved. In addition, the biennial and triennial asparagus stools are planted, the growth period is greatly shortened, and the first year of planting is the high-yield year.

AI Technical Summary

Problems solved by technology

In open-field cultivation of asparagus, due to the long seedling raising period and winter dormancy, and the short harvesting time, the yield of asparagus is low, especially in hot summer, the young leaves are easy to burn and cause sunburn, and the yield of asparagus is low and the quality is poor

In the cultivation of asparagus in greenhouses, seedlings are usually raised, coupled with continuous cropping obstacles, the early yield is low, and the investment cost is high, which affects the production efficiency of the greenhouse, and the product quality cannot be guaranteed.
