Cress hydroponics method for double harvest of water celery buds and green water celery

Abstract

The invention discloses a cress shoot and green cress double-harvesting cress water planting method. The method is characterized by comprising the steps of 1 growing seedlings, 2 performing planting and 3 performing harvesting, wherein 35-45 days after field planting, after cress on a planting plate grows to 20 cm, a pair of scissors is used for harvesting thick and strong cress stems, then, cressstems are harvested every 28-35 days, after 3-4 times, tillering of cress buds under the planting plate is abundant, meanwhile, cress shoots and cress stems are harvested at the same time, then, cress stems continue to be harvested every 28-35 days, then, cress shoots and cress stems are harvested at the same time every 28-35 days, and annual circular harvesting is achieved. The method can annually circularly harvest green cress and cress shoots, the cress water planting quality can be improved, the cress water planting yield can be increased, the working environment of workers is good, the working intensity is low, the method conforms to modern agriculture development direction, and the method must bring the huge acceleration effect for cress water planting development.

Description

technical field [0001] The invention relates to the technical field of agricultural agronomy, in particular to a water-cultivation method for water-cress buds and green water-cress with double harvests every year. Background technique [0002] Cress is a perennial aquatic perennial herb of the Umbelliferae family. Cress is native to eastern Asia, and China is one of its origins. China has used the tender stems, leaves and petioles of cress for food since ancient times. It is mainly distributed in the Yangtze River Basin and the provinces and autonomous regions to the south, among which Jiangsu, Zhejiang, Hubei, Jiangxi, Anhui, Yunnan, Guizhou and Guangzhou have relatively large production areas. The national cultivation area is 25000hm 2 Left and right, there are shallow water cultivation, deep water cultivation and wet field cultivation in the cultivation methods. In addition to China, cress is abundant in China, Japan, South Korea, North Korea, Indonesia and other East ...

AI Technical Summary

Problems solved by technology

[0004] The water celery in the prior art is mainly harvested from the top part of the stalk, but in recent years, the water celery bud has been loved by people because of its whiteness like jade, fresh and tender fragrance, and the price is as high as 10 yuan / jin. The axillary buds on the stem germinate and form, and the growth depends entirely on the nutrients stored in the stem. It cannot be exposed to light, and the quality will decline after exposure to light; the water content in the growth environment should not be too high to avoid rot, and at the same time, it likes humidity and is afraid of drought.

Restricted by special cultivation technology and environment, there are few cultivations. It belongs to special vegetable cultivation. The market demand is large and the supply exceeds demand. In the prior art, greenhouse cultivation and soil-covering cultivation are generally used, and there is no relevant introduction of hydroponic celery sprouts.
