Problems solved by technology

At present, there are few types of organic-inorganic compound nutrient solutions on the market, and there are even fewer compound nutrient solutions specifically for tomato substrate cultivation, and the production cost is high, raw materials are not easy to obtain, and the process is complicated, so the effect on improving plant quality and yield is not obvious.

Embodiment Construction

[0035] The preparation method of the specific embodiment of the organic-inorganic composite nutrient solution formula for tomato matrix cultivation of the present invention comprises the following steps:

[0036] 1) Preparation of organic mother liquor:

[0037] 1.1) Put pig, cow, and sheep raw manure into fermentation tanks or piles for fermentation and decomposing. Spray an appropriate amount of microbial fermentation agent before fermentation. The water content should be controlled at about 60%. It should not be too wet or too dry. It should be placed in a shed in winter. Fermentation is used to keep warm, and it can be fermented in the open air in summer, but pay attention to rain; when the core temperature of the pile rises to about 60°C, it needs to be turned once a week, usually once a week, and once every 3 days during the peak fermentation period. When the temperature of the surrounding environment does not rise, and the color of the manure turns black and there is no...

Abstract

The invention relates to an organic-inorganic composite nutrient solution formula for tomato substrate cultivation and an application method of the organic-inorganic composite nutrient solution formula. The nutrient solution disclosed by the invention is prepared by the following method: 1), preparing an organic mother solution; 2), preparing inorganic mother liquor; and 3), mixing the organic mother solution and the inorganic mother liquor according to different mixing proportions in different growth periods to obtain the organic-inorganic composite nutrient solution for tomato substrate cultivation. The nutrient solution is comprehensive in nutrition, capable of greatly improving the taste, sugar degree and quality of fruits, low in cost, simple and convenient in preparation method and capable of effectively improving the growth speed and fertilizer utilization efficiency of tomatoes cultivated in a substrate.

Description

technical field [0001] The invention relates to the technical field of soilless cultivation, in particular to an organic-inorganic composite nutrient solution formula for tomato substrate cultivation and an application method thereof. Background technique [0002] In facility tomato production, matrix cultivation is the most commonly used soilless cultivation method, among which drip irrigation with inorganic nutrient solution is the most commonly used method of fertilization, but inorganic nutrient solution is not as good as organic nutrient solution in terms of improving fruit taste quality and sugar content. However, the content of nutrient elements such as nitrogen, phosphorus, and potassium required by plants in the organic nutrient solution is not high, and it is easy to produce defertilization phenomenon in the later stage of plant growth, resulting in reduced yield, which is rarely used in current tomato substrate cultivation. [0003] The organic-inorganic composite...
