Vegetable cultivating machine

Abstract

The invention discloses a vegetable cultivating machine which comprises a cultivating machine body and a control panel. The cultivating machine body comprises a material replenishing box, a water storing tank, a water pipe and a hydroponic groove. The material replenishing box is connected with the water storing tank through the water pipe and an electromagnetic valve. The control panel controls conduction time of the electromagnetic valve to control a proportion and the flow of a solution which enters into the water storing tank. The hydroponic groove is connected with the water storing tank through the water pipe. A liquid level switching module and a water pump control module of the control panel control a liquid level of the hydroponic groove. According to the vegetable cultivating machine, intelligent control of the vegetable cultivating machine is achieved, a user does not need prepare a nutrition solution by the hand, planting risks are greatly reduced, guardless planting is truly achieved and a planting effect is obviously improved.

Description

technical field [0001] The invention relates to a vegetable cultivation machine. Background technique [0002] The patent document with the patent number CN200910213900.3 discloses a multi-functional plant cultivation box with wide applicability. The box body includes a plant cultivation system, an environmental mediation system, and a control system. On the basis of other functions, through the control program of the cultivation and growth process parameters of various plants stored in the control system, find out the suitable plant growth environment, the temperature, humidity, light, CO 2 etc. are controlled by the control system without human intervention. However, this plant incubator cannot adjust the pH value of the cultivation environment, and the crops absorb elements unevenly during the growth process, so that the plants cannot grow well during the growth process. [0003] The existing hydroponic planting system requires the user to prepare the nutrient solution ...

AI Technical Summary

Problems solved by technology

However, this kind of plant incubator cannot adjust the pH value of the cultivation environment, and the crops absorb elements unevenly during the growth process, so that the plants cannot grow well during the growth process.

[0003] The existing hydroponic planting system requires the user to adjust the nutrient solution according to the guide ratio, completely relying on the manual operation of the user, and it is difficult to ensure that the allocation is within a reasonable range required for crop growth

During the growth process of different crops in different periods, the absorption of various elements is unbalanced. If they absorb more cations, the nutrient solution will become acidic (H+ ionization), and if they absorb more anions, it will make the nutrients The liquid becomes alkaline (OH - ionization), this process changes significantly with the amount of transpiration, once the imbalance exceeds the threshold required for crop growth, it will lead to crop maladaptation, poor growth and even death
