Automatic constant-temperature soilless planter realizing water taking and solution supplement from gas source

Abstract

The invention provides an automatic constant-temperature soilless planter realizing water taking and solution supplement from a gas source and particularly relates to a self-water-supply cultivating device. The planter comprises a cultivating container, wherein a water supply device capable of providing a water source is arranged on the side of the cultivating container and comprises a low-power compressor, a condenser, a throttle and an evaporator, and the low-power compressor, the condenser, the throttle and the evaporator are connected sequentially; a condenser water collecting disc and an evaporator water collecting disc are arranged below the condenser and the evaporator respectively; a water tank is connected with the water inflow end of the cultivating container, and water outflow ends of the condenser water collecting disc and the evaporator water collecting disc are connected to the water tank. The planter has the beneficial effects as follows: 1, cooling or heating can be realized through switching of a four-way valve, and the temperature in a planting greenhouse can be automatically adjusted to the crop growth temperature; 2, the evaporator or the condenser produces condensate water during operation for irrigating the cultivating container, tap water supply is not needed, and the condensate water is fully used for irrigation; 3, the water level is detected by a first water level sensor, and death of plants due to too high immersion water level is avoided; in addition, a second water level sensor and a third water level sensor are used for controlling the water level in the water tank and the water level of a cultivation solution supplementing tank respectively.

Description

technical field [0001] The invention relates to the technical field of planting, in particular to a soilless planter with automatic constant temperature and air source water intake and liquid replenishment. 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 re...
