Problems solved by technology

[0002] Watercress is a perennial aquatic herb of the cruciferous family Watercress. It is also known as watercress, watercress, cold dish, and resistant lettuce. Watercress has high nutritional value and medicinal value. In Zhenjiang, it is mainly cultivated in winter and spring protected areas. In autumn and winter, open-field paddy fields are mainly cultivated, and there is also a small amount of cultivation in the suburbs. Traditionally, open-air cultivation is generally used in the middle and lower reaches of the Yangtze River, which leads to low yields of watercress. In addition, the cultivation methods are not suitable, resulting in poor quality and limited improved nutritional value

Embodiment 1

[0018] The watercress greenhouse cultivation method of the present embodiment may further comprise the steps:

[0019] A. Shed hydroponics:

[0020] Set up a greenhouse, but do not cover the greenhouse film. Pre-set the planting board in the greenhouse and prepare the nutrient solution. The composition and ratio of the nutrient solution are: calcium nitrate 330g / T, ammonium phosphate 75g / T, ferric chloride 85g / T and add water;

[0021] B. Seedling cultivation:

[0022] Take the 10 cm long branches of the mother plant, and apply them directly to the holes of the planting plate at a distance of 5 cm × 10 cm, insert 2 branches in each hole, and cover the greenhouse with a greenhouse film at the same time;

[0023] C. Management:

[0024] The temperature in the greenhouse is controlled at 20°C by managing the ventilation of the greenhouse;

[0025] E. Harvesting:

[0026] After maturity, you can start harvesting, and you can harvest according to the growth state when harvesti...

Abstract

The invention discloses a method for cultivating watercress in greenhouses. The method includes steps of A, carrying out greenhouse construction and hydroponics, to be more specific, setting up the greenhouses without greenhouse film covering, presetting field planting plates in the greenhouses and preparing nutrient liquid; B, growing seedlings, to be more specific, acquiring branches with the lengths of 10-12 centimeters from mother plants, directly applying 2-4 branches into each hole in the field planting plates according to the distances of 5*10 centimeters and covering the greenhouses with greenhouse films; C, managing air release modes for the greenhouses; E, harvesting the watercress. The method has the advantages that the temperature conditions can be controlled by the aid of thegreenhouses, reasonable hydroponics modes are adopted, accordingly, the traditional plant disease and insect pest conditions can be effectively prevented, the quality of morning glory produced by theaid of the method and components of the nutrient liquid can be guaranteed, the quality of the watercress grown by the aid of the method can be greatly improved, and effects of clearing dryness, moistening lungs, eliminating phlegm, stopping cough, inducing diuresis and the like can be realized by the watercress; the method is simple, the culture cost can be reduced, and the economic benefit can beincreased.
