Liquid-adaptive, light-adaptive and air-permeable soilless culture device

Abstract

The invention discloses a liquid-adaptive, light-adaptive and air-permeable soilless culture device, and belongs to the technical field of soilless culture. A plurality of culture cavities with waterproof breathable films are formed at the top end of a culture vessel, so that the breathability of the soilless culture environment is facilitated, whether liquid exists in the culture cavities or notis detected in real time through a liquid sensor, when the liquid amount is insufficient, a supply pipe is controlled by an external controller to automatically supplement liquid, meanwhile, residualliquid is pumped back to a lower backflow cavity through a guide-out pipe, PH detection is conducted through a PH meter, PH adjustment is conducted through an acid-base adding pipe, and after the PH value is equal to the proper value, a residual nutrient solution can be guided back to an upper liquid supply cavity through a suction pump to be recycled, in addition, the top end of the culture vessel is covered with a light-transmitting protective cover embedded with a magnetic ball, and when a magnetic attraction device in a magnetic rotating bag is heated to work, an elastic light-transmittinglayer is forced to extrude inwards to shrink to a certain extent, so that the light-transmitting area is reduced, a certain shading effect is achieved, and the culture temperature and illumination can be adjusted conveniently.

Description

technical field [0001] The invention relates to the technical field of soilless cultivation, and more specifically relates to a soilless cultivation device suitable for liquid, light and air. Background technique [0002] Soilless cultivation is a technique for cultivating crops without soil. The fertilizer and water conditions required for crop development are completely provided by nutrient solution, which can effectively avoid soil pollution to a certain extent, and also save water and fertilizer. role. [0003] Nutrient solution and its preparation management technology as well as the preparation of soilless cultivation devices are important contents of soilless cultivation. But the existing soilless culture is not easy to control the replenishment of the culture solution, especially for the plant cultivation with relatively luxuriant plants, it is not easy to observe the capacity of the culture solution in the culture container, and the soilless culture is annoying bec...

Problems solved by technology

But the existing soilless culture is not easy to control the replenishment of the culture solution, especially for the plant cultivation with relatively luxuriant plants, it is not easy to observe the capacity of the culture solution in the culture container, and the soilless culture is annoying because the culture solution blocks the roots of the cultivated plants Contact with the air, which affects the growth of plants;

[0004] Secondly, most of the media for soilless cultivation are neutral, with a pH of about 7 and unlike soil, which has no buffering capacity for acid and alkali, and fertilizers are generally acid and alkali, so the pH fluctuates extremely during fertilization High, and when the pH value of the nutrient solution is not within the appropriate range, it is difficult to achieve a good cultivation effect. In addition, the growth environment temperature of soilless cultivation is also particularly important. A suitable growth temperature is the key to the healthy growth of plants
