Problems solved by technology

The traditional open-air production of vegetables is completely restricted by natural conditions. The yield per unit area of ​​land is low, and because some vegetables cannot be continuously cropped, the land utilization rate is low. When encountering severe weather, severe heat and cold, production and income are often reduced, and pesticide and heavy metal pollution are unavoidable. It is difficult for us to eat real "hygienic" green vegetables

[0035] Embodiment 2 Chinese cabbage hydroponic method 1

[0036] Select spring cabbage as the hydroponic object. Hydroponics time: May 1, 2014.

[0037] (1) Seed treatment and germination: Wash the spring cabbage seeds with clean water to remove impurities and seed surface pollutants, then soak them in the seed soaking solution for 2 hours, and control the temperature at 18°C ​​until the buds are 2 cm long. It is made by mixing 0.1% hydrogen peroxide and 0.05% potassium dihydrogen phosphate solution at a mass ratio of 1:1.

Abstract

The invention discloses a pakchoi water culture method. The method comprises the following steps of seed treatment and germination accelerating, sowing, transplanting, management and harvesting. A water culture nutrient solution is prepared by adding 30-50 mL of tofu waste water, 10-20 mL of tea bran water, 20-30 mL of molasses fermentation liquor, 220-250 mg of ammonium nitrate, 5-8 mg of sodium molybdate, 3-5 mg of borax, 3-5 mg of calcium nitrate, 6-10 mg of ferrous sulfate, 1-3 mg of manganese sulfate, 1-3 mg of zinc sulfate and 1-3 mg of copper sulfate into each liter of pigsty liquid dung. The pH value of the nutrient solution is adjusted to be 5.8-6.5 by using citric acid. The electric conductivity is controlled to be 1.5-2.5 mS / cm, and the dissolved oxygen amount is 4-5 mg / L. Waste water resources are fully utilized, waste is turned into wealth, organic, safe and pollution-free pakchoi is harvested, and the popularization value is relatively high.

Description

technical field [0001] The invention belongs to the field of plant cultivation, and in particular relates to a hydroponic method for pakchoi. Background technique [0002] cabbage, Brassica campestris L. ssp. chinensis Makino (var. communisTsen et Lee), commonly known as green vegetables, also known as jelly vegetables, ladle vegetables, ladle white, rapeseed, oily cabbage, etc., belong to the genus Brassica of Brassicaceae. Chinese cabbage is one of the vegetables richest in vitamins and minerals. It provides material conditions to ensure the physiological needs of the body and helps to enhance the body's immunity. In addition, cabbage contains more carotene than beans, tomatoes, and melons, and is rich in vitamin C. After entering the human body, it can promote skin cell metabolism, prevent skin roughness and pigmentation, and make skin bright and clean. anti aging. [0003] my country's pig industry has gradually moved from tradition to modernization in recent years. ...
