Saline-alkali soil tetraploid purple asparagus cultivation method

Abstract

The invention discloses a saline-alkali soil tetraploid purple asparagus cultivation method. Tetraploid purple asparagus is high in sugar content, low in coarse fiber content, strong in growth vigor,high in yield potential, good in color and luster, excellent in quality, excellent in taste and strong in disease resistance. The tetraploid purple asparagus cultivation method includes the steps: first, soil treatment; second, seedling culture; third, purple asparagus seedling culture management; fourth, planting furrow opening; fifth, seedling digging and selection, and planting transplantation;sixth, purple asparagus field management; seventh, pest control; eighth, harvesting. Saline-alkali soil is improved, the contradiction of competing for land by vegetables and grains can be relieved,and the planted tetraploid purple asparagus is large, succulent, slightly sweet, delicate in texture, low in fiber content, excellent in quality, excellent in raw taste and strong in disease resistance and has the advantages of high planting survival rate, stable yield, cost saving property and the like.

Description

technical field [0001] The invention relates to the technical field of asparagus cultivation, in particular to a cultivation method of tetraploid purple asparagus in saline-alkali land. Background technique [0002] Purple asparagus, the American fruit-type sweet purple asparagus, is a very valuable vegetable. It is the only asparagus vegetable that can be eaten raw. It is the first choice for anti-cancer and anti-cancer food. In European countries, Japan, and Southeast Asia, long-term consumption of asparagus can promote blood circulation and promote menstruation, overcome human fatigue, and have auxiliary therapeutic effects on hypertension, heart disease, hepatitis, liver cirrhosis, nephritis, edema, and cystitis. [0003] Long-term consumption of American fruit-type sweet asparagus can help digestion, enhance appetite, improve body immunity, reduce the damage of harmful substances, inhibit the production of cancer cells, and have a good anti-cancer and anti-cancer effect...

AI Technical Summary

Problems solved by technology

The female stems are harvested, and the female stems are topped at 1.5m to prevent lodging. This method not only solves the problems of lack of seedlings, broken ridges and low survival rate after planting in traditional cultivation techniques, but also achieves high and stable yields of asparagus. However, the "Apollo ", "Champion" are white and green varieties, this cultivation method is not suitable for the planting of tetraploid purple asparagus, and the order of nutrition and color of asparagus from dark to light is black, purple, green, red, yellow, white , so the nutrition of purple asparagus is higher than that of green asparagus and white asparagus
