Abstract

The invention relates to a Chinese cabbage rooting-promoting hydroponic nutrient solution and a preparation method thereof. The Chinese cabbage rooting-promoting hydroponic nutrient solution comprises the following components: potassium nitrate, ammonium nitrate, monopotassium phosphate, magnesium sulphate, calcium chloride, potassium iodide, boric acid, manganese sulfate, zinc sulfate, sodium molybdate, nickel sulfate, copper sulfate, cobalt chloride, EDTA (Ethylene Diamine Tetraacetic Acid) disodium, ferrous sulfate, inositol, glycine, thiamine hydrochloride, pyridoxine hydrochloride and nicotinic acid. The invention discloses a hydroponic nutrient solution formula aiming at Chinese cabbage rooting-promoting and a preparation method thereof for the first time; through performing hydroponic culture on unrooted Chinese cabbages, the nutrient solution can enable the unrooted Chinese cabbages to root again and can also provide adequate nutrition to promote reproductive growth, and the growth vigor in transplanted soil is good.

Description

technical field [0001] The patent of the invention relates to a hydroponic nutrient solution for promoting rooting of Chinese cabbage and a preparation method thereof, belonging to the technical field of agricultural science plant soilless cultivation. Background technique [0002] Vegetable hydroponic technology is a relatively advanced cultivation method in soilless cultivation. Vegetable hydroponics not only improves the land use rate, but also reduces the use of pesticides and heavy metal pollution. In view of this, vegetable hydroponics technology can effectively solve the problem of insufficient supply of vegetables in the off-season. Vegetable hydroponic technology has been introduced into my country since the 1940s, and the industrialization of hydroponic vegetables was formed in the mid-1980s. At this stage, the main vegetable hydroponic technologies include deep liquid flow method, nutrient liquid film technology and floating plate capillary technology. Compared w...
