Heat supply and heat preservation system for plant planting

Abstract

The present invention discloses a heat supply and heat preservation system for plant planting. The heat supply and heat preservation system for plant planting consists of a greenhouse space, a plurality of plant growth slideways, a plurality of heat supply devices and a plurality of planting boxes, a plant input port and a plant output port are arranged on side surfaces of the greenhouse space, the rest parts are arranged in a sealing way, a plurality of the plant growth slideways are arranged in the greenhouse space between the plant input port and the plant output port, a support frame is arranged at bottom parts of the plant growth slideways, a plurality of the planting boxes are distributed on the plant growth slideways, soil is laid in the planting boxes, and plants are planted in thesoil; and a plurality of heat supply devices are laid under the planting boxes. The plant planting boxes are elevated, the heat supply devices are laid under the plant planting boxes, the soil is fully laid in the planting boxes, heat is spread upwards and directly enters the soil, the soil has a heat storage function, heat loss is reduced, heat required for plant growing roots and surroundings is ensured, existing national soil resources are not damaged, and at the same time, the heat supply and heat preservation system is suitable for the soil which is not suitable for plant growth such assaline-alkali soil and polluted soil.

Description

technical field [0001] The invention belongs to the technical field of greenhouse planting, and in particular relates to a heat supply and heat preservation system for plant planting. Background technique [0002] China is a large agricultural country. In recent years, the cultivation of greenhouse vegetables has developed rapidly in our country. The scale of various agricultural greenhouses has continued to expand, and the area of ​​agricultural greenhouses has occupied the first place in the world. As a major breakthrough in agricultural technology, greenhouses have improved the growth of crops. The environment accelerates the growth of crops and shortens the growth cycle. At present, it has been widely used in various crops such as seedling cultivation, vegetable planting, and sprout cultivation. [0003] However, there are major shortcomings in the application of traditional solar greenhouses and plastic greenhouses. For example, in most parts of my country in winter, t...

Problems solved by technology

[0003] However, there are major shortcomings in the application of traditional solar greenhouses and plastic greenhouses. For example, in most parts of my country in winter, the temperature in the solar greenhouse during the day is very high, often exceeding the temperature required for plant growth, while the low temperature at night often freezes or damages the plants. affect plant growth

Therefore, the patent CN109906828A discloses a greenhouse, which at least includes an insulation layer, a telescopic ceiling, a dosing box, a water storage tank, a batching box, and a heating unit; The temperature compensation control in the greenhouse at night is beneficial to provide the temperature conditions for the growth of the plants in the greenhouse; this technical solution provides temperature compensation for the plants inside the greenhouse by installing a heating pipe in the insulation layer on the top of the greenhouse, but the heating pipe Located on the top of the greenhouse, although there is an insulation layer, the heat generally spreads upwards. The heat in the insulation layer directly exchanges heat with the outside atmosphere, and the heat loss rate is high; in addition, plant growth is more sensitive to root temperature. The growth temperature of the plant affects the growth of plants and the accumulation of dry matter above and below the ground, the ratio of root to shoot and the growth rate of leaves. In this technical solution, the heat transmitted inward from the insulation layer can reach the The heat in the roots of plants is very little, which cannot meet the temperature requirements of plant growth
