Abstract

The invention discloses a plant soilless culture nutrient solution circulating device. The device comprises a nutrient solution supply and processing unit, a nutrient solution circulating unit and a control unit, wherein the nutrient solution supply and processing unit is used for supplying and processing a nutrient solution required by plants; the nutrient solution circulating unit is connected with the nutrient solution supply and processing unit and used for performing liquid circulation, and the nutrient solution circulating unit, the nutrient solution supply and processing unit and an external culture bed form a closed culture system; the control unit is connected with the nutrient solution supply and processing unit and the nutrient solution circulating unit respectively; and the closed culture system has a working mechanism imitating blood and oxygen supply of a biological heart. According to the device, content of all components of the plant soilless culture nutrient solution is detected, and effective supply regulation of the important components is conducted according to plant nutrient demands, so that the circulated nutrient solution can be recycled repeatedly, actual demands of the plants for nutrients at different stages can be met, and pollution to the environment is avoided. In addition, the invention further provides a plant soilless culture nutrient solution circulating control method.

Description

technical field [0001] The invention relates to the technical field of plant soilless cultivation, in particular to a plant soilless cultivation nutrient solution circulation device and a control method. Background technique [0002] Plant nutrient hydroponics belongs to the soilless cultivation mode. It is a cultivation mode that replaces soil to provide plants with the necessary nutrients for growth. It gets rid of a series of soil pan-salt, soil-borne diseases and insect pests and continuous cropping obstacles brought about by traditional soil cultivation. It has the advantages of fast growth, good quality and stable output. Rational use of nutrient hydroponics plays an important role in promoting the development of modern agriculture. [0003] However, in actual production and application, the use of nutrient solution is almost disposable, and the discarded nutrient solution is rich in nutrients, which is not only a waste, but also causes a certain degree of pollution t...
