Water circulating system for soilless planting

Abstract

The invention particularly relates to a water circulating system for soilless planting. The water circulating system comprises a frame body, a solution storage tray and a first field planting tray, wherein the solution storage tray and the first field planting tray are placed on the frame body separately, a water pump is fixed on the frame body, an input end of the water pump is connected with the solution storage tray, an output end of the water pump is connected with a solution conveying pipe, a water outlet of the solution conveying pipe is placed on the first field planting tray, a first electromagnetic valve which is used for controlling solution supplying volume is arranged on the solution conveying pipe, a water return end of the first field planting tray is connected with a solution return pipe, a fourth electromagnetic valve which is used for controlling water discharge is arranged on the solution return pipe, and one end of the solution return pipe is connected with the solution storage tray. The water circulating system for soilless planting has the beneficial effects that water levels in the first, second and third field planting trays are controlled separately by using the first electromagnetic valve, a second electromagnetic valve, a third electromagnetic valve, the fourth electromagnetic valve, a fifth electromagnetic valve and a sixth electromagnetic valve, and sufficient nutrient solution is supplied in time according to a monitored nutritive value in a manner of being matched with a first detection sensor.

Description

technical field [0001] The invention relates to the technical field of soilless cultivation, and more specifically, relates to a water circulation system for soilless cultivation. Background technique [0002] The fundamental difference between soilless cultivation and conventional cultivation is that plants can be cultivated directly with nutrient solution without soil. In the current soilless culture technology, in order to fix the plants and increase the air content, most of them use gravel, peat, vermiculite, perlite, rock wool, sawdust, etc. , light, nutrient and air requirements, the difference between soilless cultivation and conventional cultivation is: it does not depend on soil, it can expand the scope of cultivation, effectively control and accelerate the growth of crops, improve the quality of crops, and is suitable for factoryization, scale and customization The development of modernized agriculture can reduce manual operations and reduce labor costs for crop...

AI Technical Summary

Problems solved by technology

When planting melons, the roots of melons generally have a strong absorption capacity, which makes the nutrient difference between the beginning and end of the planting tray larger, resulting in melons at the end being more prone to nutrient deficiencies, which ultimately affects the melons in the overall planting tray uneven growth
