Cultivation method of hydroponic leafy vegetables

Abstract

The invention discloses a cultivation method of hydroponic leafy vegetables. According to the cultivation method, leafy vegetable seedlings are planted in a rail-type hydroponic cultivation strip erected on a cultivation tank for breeding; a special hydroponic liquid for leafy vegetables is placed in the cultivation tank; the special hydroponic liquid for leafy vegetables contains calcium nitrate,potassium nitrate, potassium fulvic acid, magnesium sulfate, nostoc sphaeroides algae and hydroxypropyl cellulose; and the rail-type hydroponic cultivation strip comprises a cultivation strip body, wherein the middle part of the cultivation strip body is provided with a strip-shaped rail in the length direction, and planting holes capable of sliding along the length direction of the cultivation strip body are arranged in the strip-shaped rail, and are used for planting the leafy vegetable seedlings. The leafy vegetable hydroponic cultivation is carried out by adopting the method provided by the invention, and the planting distance can be adjusted according to different leafy vegetable varieties, so that the realization of rational close planting is facilitated, and the space waste is reduced; moreover, the hydroponic liquid has stable performance, so that the loss of nitrogen element can be avoided, and the growth of the leafy vegetables can be better promoted.

Description

technical field [0001] The invention belongs to the technical field of soilless cultivation, and in particular relates to a method for cultivating hydroponic leaf vegetables. Background technique [0002] Hydroponics is a soilless cultivation method in which the roots of plants grow directly in a nutrient solution. Compared with soil cultivation, hydroponics eliminates the trouble of cleaning caused by contact with soil and substrate, and its growth cycle is short and turnover is fast; at the same time, compared with soil cultivation leaf vegetables, hydroponic leaf vegetables are clean, fresh and tender, Good taste and high quality. Therefore, the vast majority of green and pollution-free leafy vegetables are carried out in hydroponics. Contents of the invention [0003] The purpose of the present invention is to provide a novel cultivation method of hydroponic leafy vegetables, which can not only adjust the planting distance according to different leafy vegetable varie...
