Greenhouse cabbage nutrient solution and preparation method thereof

Abstract

The invention provides a greenhouse cabbage nutrient solution and a preparation method thereof. The greenhouse cabbage nutrient solution comprises, by weight, 20-65 parts of macroelements, 0-15 partsof microelements, 0-5 parts of growth regulators and 0-5 parts of bactericides which are broad-spectrum bactericides, with the balance being water. The pH ranges from 5.5 to 7. The microelements are firstly stirred in the water through a reaction kettle till all the microelements are dissolved; in the dissolving process, a circulating pump is started for continuous stirring, the macroelements areadded after complete dissolution, all the components are added one by one in the adding process, then the growth regulators and the bactericides are added and fully dissolved, and water is added for quantification. The cabbage planting efficiency is effectively improved, the cabbage planting survival rate is increased, healthy production of cabbage plants is facilitated, the resistance of the cabbage plants to diseases and insect pests is effectively improved, meanwhile, damage of diseases in water and air to the cabbage plants is avoided, and the utilization rate of the nutrient solution is increased; the pollution of the nutrient solution to the environment is reduced and the environmental protection is improved.

Description

Technical field [0001] The invention relates to a plant nutrient solution, in particular to a greenhouse cabbage nutrient solution and a preparation method thereof. Background technique [0002] Cabbage is one of the main vegetable varieties in my country. As the planting area increases year by year, it has become one of the main economic income of vegetable farmers. In the process of planting cabbage, the seeds are planted by planting cabbage seeds. Therefore, the quality of cabbage seeds needs to be ensured during the cultivation of cabbage seeds. The preparation of cabbage seeds needs to go through a series of processes such as seedling raising, seedling transplanting, overwintering management, seed plant planting in the following spring, cross-pollination, harvesting of pods, and threshing. [0003] There are two existing methods for raising cabbage seedlings, one is open field seedlings and the other is plug seedlings. Among them, open field seedlings are relatively extensiv...

Problems solved by technology

[0005] However, in the process of use, with the growth and development of cabbage and the presence of some bacteria in the water body, it will harm cabbage after a long time, affect the healthy growth of cabbage, and cause diseases and even death of cabbage seedlings.
