Year-round cultivation pattern for watercress

Abstract

The invention discloses a year-round cultivation pattern for watercress. The year-round cultivation pattern for the watercress comprises outdoor cultivation and protected cultivation. The outdoor cultivation comprises the spring and autumn low-altitude area outdoor cultivation and the summer high-altitude area outdoor cultivation. The protected cultivation comprises the summer low-altitude area protected cultivation and the winter low-altitude plain protected cultivation. The sowing time of the spring and autumn low-altitude area outdoor cultivation is the mid-to-end April and the early-to-middle August every year, the sowing time of the summer high-altitude area outdoor cultivation ranges from May to the first ten-day period of June every year, the sowing time of the summer low-altitude area protected cultivation is the last ten-day period of May every year, and the sowing time of the winter low-altitude plain protected cultivation ranges from October to March. By means of the year-round cultivation technology for the watercress, the defect of seasonality of the watercress is overcome, the technical scheme of planting the watercress for a long time is provided, and environment-friendly and pollution-free fresh vegetables can be provided for the market all the year round. Thus, the year-round cultivation technology for the watercress has market advantages and economic significance.

Description

technical field [0001] The invention belongs to the field of crop cultivation, and in particular relates to a watercress annual cultivation mode. Background technique [0002] Watercress, also known as watercress, watercress, and watercress, is the whole herb of Nasturtium cfficinale R.Br, a plant of the genus Nasturtium in the family Cruciferae. Watercress also has nutritional, medicinal and dietary value functions: watercress has comprehensive nutrients, not only containing protein, fat, sugar (glucose, sucrose and fructose) and inorganic salts (Na, K, Ca, Fe , Mg, Zn, etc.) and other mineral elements necessary for the human body, but also rich in superoxide dismutase (ie SOD) with anti-aging effects; At the same time, it is sweet and slightly bitter, cold in nature, and also has the effects of clearing dryness and moistening lungs, resolving phlegm and relieving cough, and diuresis. In addition, in terms of clinical medicine, watercress can interfere with egg implantati...

Problems solved by technology

[0003] However, watercress is very seasonal. Generally, watercress in the main planting area is limited by seasons and can only be sold in winter, which cannot meet people’s demand for watercress in other seasons. Moreover, there is currently no literature showing that watercress can be grown in a certain area. Therefore, it is urgent to select a pollution-free area for the annual cultivation of watercress, and the prior art has not disclosed the technical scheme of its annual cultivation, so it is of great significance to develop its annual cultivation model
