Heat preservation type greenhouse and heat preservation method thereof

Abstract

The invention discloses a heat preservation type greenhouse and a heat preservation method thereof and solves the problem that the survival rate of crops in plateau or desert belts is low or the plateau or desert belts cannot be developed in the prior art. The greenhouse comprises a greenhouse body and an energy storage body, wherein the greenhouse body is located at the upper part (or the side part) of the energy storage body, a pumping driving mechanism is arranged in the greenhouse body, and a fertile soil layer is arranged at the bottom of the greenhouse body; a constant temperature body is arranged in the energy storage body, and a circulating mechanism is arranged in the constant temperature body and connected with the pumping driving mechanism. The greenhouse is a greenhouse devicefor the plateau and desert belts, local resources can be used by the energy storage body according to the actual terrain, the cost is saved with the adoption of a sandpit or water pool or manual construction, and resources are sufficiently utilized. Gas in the greenhouse body enters the constant temperature body through the circulating mechanism for heat exchange, so that the temperature in the greenhouse body is always kept in the range suitable for crops, and the crop growth rate is increased.

Description

technical field [0001] The invention relates to the technical field of agricultural engineering, in particular to a heat preservation and temperature storage type greenhouse and a heat preservation and temperature storage method thereof. Background technique [0002] my country is a large country with a population of 1.4 billion. Although the arable area is vast, the per capita arable land area is less than 1.5 mu, and these arable lands are mainly concentrated in several major plains in my country. The agricultural development is very unbalanced across the country. The Qinghai-Tibet Plateau, the Yunnan-Guizhou Plateau, the Loess Plateau, and the large deserts in the west and northwest of my country are relatively slow to agricultural development. How to make full use of the land resources in these areas is the key point of agricultural development. [0003] For example, although the Qinghai-Tibet Plateau is relatively cold, it has plenty of sunshine, with about 3,100 hours ...
