Solar greenhouse suitable for facility cherry cultivation

Abstract

The invention discloses a solar greenhouse suitable for facility cherry cultivation. The solar greenhouse comprises shed columns and a light-transmitting layer (1). The solar greenhouse is characterized in that the shed columns and the light-transmitting layer (1) form a solar shed. The light-transmitting layer (1) is provided with a heat collecting device. The solar shed is internally provided with a uniform air inlet device, an automatic control device, and a cooling device. The solar greenhouse solves problems that a system is poor in heat dispersion, non-uniform in pipeline air intake, and low in system operation efficiency, and a heat collection device is added, so sunlight utilization is more sufficient. A hot blast heater temporary warming system is also added, so as to automatically warm soil and air in the greenhouse when extreme weather occurs in facility cherry production, so that a cherry germination period is brought forward, and a flowering phase is brought forward, branch growth amount in an earlier stage is improved, first-class high-quality fruit rate is improved, a fructescence is brought forward, cherries appear on the market in advance, and yield is increased.

Description

technical field [0001] The invention relates to a solar greenhouse, in particular to a solar greenhouse suitable for facility cherry cultivation. Background technique [0002] The solar greenhouse is a unique form of greenhouse in my country. It is widely distributed in northern China and has brought high economic benefits to people. In Northwest and Northeast China, due to the low outdoor temperature in winter and spring, the outdoor temperature is generally below -10°C on sunny days with good light. Diseases, solar greenhouses are generally closed all day during production in winter and spring. Moreover, due to the frequent irrigation and watering of crops and the transpiration of the plants themselves, the indoor air cannot be exchanged with the outdoor air in time, so that the indoor moisture content gradually increases. The yield, quality and product supply time of crops reduce the production efficiency of solar greenhouses. [0003] In actual production, in order to...

AI Technical Summary

Problems solved by technology

In order to improve the uniformity of the air intake, this patent increases the number of fans and artificially turns on the fans according to the indoor temperature. This not only greatly increases the initial investment cost and operating cost, but also reduces the operating performance and efficiency of the system due to human factors.

At the same time, the cooling area of ​​the heat dissipation pipes of the system is small, the heat dissipation distribution is uneven, and the heat transfer to the soil is insufficient, resulting in poor heat dissipation performance of the heat dissipation system.

Therefore, the present invention proposes a solar greenhouse suitable for facility cherry cultivation, which not only solves the problems of poor heat dissipation performance of the above-mentioned system, uneven air intake of the pipeline, and low operating efficiency of the system, but also increases the heat collection device to make full use of sunlight. , also added a temporary heating system of the hot blast stove, which automatically warms the soil and air in the greenhouse in case of extreme weather during the cherry production in the facility, so that the cherry germination period is advanced, the flowering period is advanced, the growth of branches in the early stage is increased, and the rate of first-class high-quality fruit Improvement, the fruit ripening period is advanced, the market is early, and the yield increases
