Solar greenhouse floor heating planting device

Abstract

The invention relates to the technical field of solar soil heating systems, in particular to a solar greenhouse floor heating planting device. The device comprises a solar heating system (1), a heat preserving and water storage device (2), a floor heating device (3) and a recycling water storage tank (4). The solar heating system (1) is connected with the heat preserving and water storage device (2) through a water pump I (5), the heat preserving and water storage device (2) is connected with the floor heating device (3) through a water pump II (6), the floor heating device (3) is connected with the recycling water storage tank (4) through a water pump III (7), and the recycling water storage tank (4) is connected with the solar heating system (1) through a water pump IV (8). The floor heating device (3) is embedded under the root system of crops. The device has the advantages that the structure is simple, operation is convenient, soil temperature is increased, crop growth is promoted, the crop yield is increased, greenhouse year-round high-quality planting is achieved, water can be supplied to floor heating pipes continuously, and temperature control is precise.

Description

technical field [0001] The invention relates to the technical field of solar soil heating systems, in particular to a solar greenhouse floor heating planting device. Background technique [0002] The use of greenhouses for vegetable production can not only ease the supply of vegetables in winter in northern regions, but also obtain higher economic benefits. The production of greenhouse vegetables in winter has become an effective way for farmers to make a fortune. Due to the complex weather changes in winter, it will be difficult to achieve high yield and high efficiency without strengthening the management of greenhouse vegetables. Because the soil temperature in the greenhouse is low, it seriously affects the growth of crops, especially in the coldest season, because the ground temperature is too low, the root system stops growing, and even causes freezing damage. The output is not high at the stage of the highest price of agricultural products in winter, which has a grea...

Due to the complex weather changes in winter, it is difficult to achieve high yield and high efficiency without strengthening the management of greenhouse vegetables

Because the soil temperature in the greenhouse is low, it seriously affects the growth of crops, especially in the coldest season, because the ground temperature is too low, the root system stops growing, and even causes freezing damage. The output is not high at the stage of the highest price of agricultural products in winter, which has a greater impact on the production efficiency of the greenhouse. large; and the existing solar heating systems are all set outside the greenhouse to heat the air in the greenhouse to ensure that the plants will not be frozen to death in the cold winter, but they cannot directly heat the roots of the plants, preventing plant growth

[0003] As we all know, the heat capacity of the soil is larger than that of the air, so at the same heating temperature, the soil needs more heat to heat up, and the soil temperature is not easy to rise, while the heat capacity of the air is the smallest, and the temperature of the air is easy to rise, which greatly increases The temperature of the greenhouse, so that the air temperature in the greenhouse will be too high, sometimes even burning the stems and leaves of the plants

The patent No. is CN204146111U, and the name is a utility model patent of a solar soil heating system for automatically controlling a solar greenhouse, which solves the above-mentioned problems; The temperature of the hot water in the heater, and when the cold water in the solar heater is insufficient and there is no reserve water, it will cause the problem of not being able to continuously supply water like the floor heating heating pipe
