Soilless vegetable cultivation machine

Abstract

The invention relates to a soilless vegetable cultivation machine which comprises a cultivation rack and a constant-temperature tank. A plurality of vertically arrayed cultivation layers are arranged in the cultivation rack and are sequentially connected with one another by drain pipes, a culture fluid tank is communicated with a spray pipe in the uppermost cultivation layer via a suction pipe, and a lowermost culture fluid groove is communicated with the culture fluid tank via a drain pipe; the constant-temperature tank is arranged at the bottom of the cultivation rack, and a temperature control assembly b and a temperature sensor b are arranged inside the constant-temperature tank; the culture fluid tank and a seedling raising assembly are arranged inside the constant-temperature tank, and a filter box is further arranged in the culture fluid tank; the constant-temperature tank is communicated with a temperature control chamber via an air channel, and the temperature control chamber is positioned on the top of the cultivation rack; an air outlet is formed in a side wall of each cultivation layer and is connected with a pipe of the air channel. The soilless vegetable cultivation machine has the advantages that the soilless vegetable cultivation machine is applicable to domestic and small-scale vegetable cultivation and vegetable production of indoor medium and large plant factories and is low-nitrate, green and healthful vegetable production equipment free of pesticides, hormone and heavy metal residues.

Description

technical field [0001] The invention relates to a plant cultivation equipment, in particular to a vegetable soilless cultivation machine. Background technique [0002] Vegetables contain many nutrients and are essential food for people's life. Vegetables are traditionally grown in a natural environment, requiring land, sunlight, irrigation facilities and a lot of equipment. With the surge of people's demand for vegetables, in order to obtain vegetables as soon as possible, various chemicals and pesticides will be added during the planting process of vegetables; in addition, due to the pollution of land and water resources, the content of toxic and harmful substances in vegetables is also increasing day by day; And these are harmful to the human body, and it is difficult to fundamentally overcome them at present. [0003] In addition, the supply of land is also increasingly tight. Opening up vast farmland for growing vegetables is quite a luxury for some cities, so a more ...
