What are the advantages of smart glass greenhouses? How to take advantage of agricultural planting
1. Introduction and advantages and disadvantages of smart glass greenhouse
The smart greenhouse is a kind of greenhouse with a light steel structure and covered with glass on the top and all sides. The standardization of intelligent greenhouses in the Netherlands is equipped with shading systems, ventilation systems, cooling systems, heating systems and various environmental control parameter collection systems. This kind of intelligent greenhouse is a kind of modern intelligent facility equipment finally chosen by horticultural growers in developed countries after nearly a hundred years of development and improvement. The greenhouse is covered with all glass, with high light transmittance, and the anti-reflection glass can scatter the light. This model of intelligent greenhouse adopts fully mechanized control, replacing the backward production method judged by manual experience, and everything is controlled by data precision.
The smart greenhouse provides a stable growth environment for agricultural crops, and is no longer affected by the external rain and snow climate, so that the growth of crops can be achieved optimally. For example, taking a large fruit tomato as an example, the output of one square meter can be as high as 70 kilograms in a 50-story greenhouse, which is three to five times the output of ordinary vegetable greenhouses. At the same time, the water consumption and labor usage are three to five times that of traditional greenhouses. one.
At present, the main problems facing domestic growers are the relatively high investment cost of greenhouses and the high energy consumption in winter production in northern regions. As the price of a square meter of imported smart glass greenhouses is as high as 15002000 yuan / square meter, if there is no support and subsidies from the national government, it is difficult for individuals, agricultural cooperatives or companies to invest, because after several years of The development of domestic greenhouse companies has also been able to build smart greenhouses of the same specifications and styles, but the cost is less than half. Secondly, the high energy price in my country makes the energy cost of greenhouse users in Northeast China much more expensive in winter.
