Embodiment 1

[0036] A hydroponic planting method for spinach, comprising the following steps:

[0037] A. Germination: Choose spinach varieties with strong frost resistance. Before sowing, sterilize the seeds and soak them at a constant temperature of 40°C for 8 hours. After removing the seeds, irradiate them with UV lamps and LED fluorescent lamps. The LED fluorescent lamp is illuminated at the same time for 40 minutes, the UV lamp is turned off, the LED fluorescent lamp continues to illuminate for 1 hour, and it is placed in a cool and ventilated place for standby. The power of the ultraviolet lamp is 20w, the radiation peak is 300nm, and the power of the LED fluorescent lamp is 16w;

[0038] B. Sowing: Sow seeds in late November-early December, adopt broadcast and cover with film, remove the film after emergence, until 2-3 true leaves grow, and spinach seedlings are obtained;

[0039] C. Transplantation: Move a single spinach seedling into the seedling tank of the seedling container, fi...

Embodiment 2

[0050] On the basis of Example 1, in the hydroponic planting method of spinach, the box is made of thermal insulation plastic. The box is light green.

[0051] In winter, especially between December and January, the temperature is low and the wind is strong. For spinach seedlings grown in outdoor hydroponics, the plastic box insulation can withstand part of the severe cold and help them survive the winter. In addition, the light green box can penetrate Excessive amount of ultraviolet rays can promote the root growth of spinach seedlings and the synthesis of vitamin D.

Embodiment 3

[0053] On the basis of Example 1, in the hydroponic planting method of spinach, the seed sterilization specifically refers to using dandelion plus 10 times its weight of water to cook for 1 hour, and after filtration, the filtrate is cooled to 40-45° C. , soak the spinach seeds in the filtrate for 20min. Using dandelion to sterilize seeds is safer and more environmentally friendly than using pesticides.

[0054] In the hydroponic planting method of spinach, the substrate used for sowing is composed of vermicompost, peat and vermiculite in a volume ratio of 4:3:1. The substrate used for sowing is mainly composed of vermicompost and peat, which can improve the emergence rate of spinach seedlings. Compared with using outdoor soil to replace the vermicompost and peat, the method of the present invention increases the emergence rate by 32.7%.

[0055] The described hydroponic planting method of spinach is to sow between 10:00 am and 12:00 am in early December, so that the time can...

Abstract

The invention discloses a hydroponic cultivation method of spinach comprising following steps: A accelerating germination; B. sowing; C. transplanting: single spinach seedlings are moved into nursery tanks of a nursery container, and are exposed under ultraviolet lamps for 1 hour and exposed under LED daylight lamps for 7 hours, and then cultivated in the dark for 16 hours every day, after 3 weeks, seedling culture liquid is replaced once until harvesting. The seedling culture liquid is prepared by following components: 1.2[mu]mol / L manganous sulfate, 0.2[mu] mol / L ammonium molybdate, 0.6[mu] mol / L cobalt chloride, 0.1 [mu]mol / L cobalt chloride nickel chloride, 0.1 mmol / L 5-aminolevulinic acid, 2 mmol / L ammonia sulfate and 5 to 10 g / L extracting solution; magnetic water is used as the solvent of the seedling culture liquid, and the pH is regulated to 6.5 to 7.0. By means of the hydroponic cultivation method of spinach, the yield of hydroponic spinach in winter can be increased, the content of antioxidant substance in the spinach is increased and therefore the health care effect of spinach is enhanced.

Description

technical field [0001] The invention relates to the technical field of spinach planting. More specifically, the present invention relates to a hydroponic planting method of spinach. Background technique [0002] Spinach (Spinacia oleracea L.), also known as Persian vegetables, red root vegetables, parrot vegetables, etc., belongs to the Chenopodiaceae Spinach genus, an annual herb. [0003] Spinach is known as a "model nutrition student". It is rich in carotenoids, vitamin C, vitamin K, various minerals and other nutrients. It is a favorite home-cooked dish. With the improvement of people's living standards, people tend to prefer green vegetables that have not been sprayed with pesticides, while ordinary small traders mostly choose to spray pesticides for the sake of spinach plumpness and no pests and diseases. [0004] The cultivation of spinach is generally more common in soil. Hydroponics is a soilless cultivation method for plants, and hydroponics can avoid soil-borne ...
