Modern agriculture is agriculture developed on the basis of modern industry and modern science and technology. It refers to the extensive use of modern science and technology and modern industrial technology to transform traditional experience into relying on data science management to push agriculture into a product of specialization, regionalization, and commodity economy. The flower glass greenhouse plays an important role in the production of flowers and vegetables in my country. Today we will introduce and analyze the composition system and function of modern flower glass greenhouse. Flower glass greenhouses have been introduced and developed for more than 20 years. As the smart greenhouses in the early years have gradually changed from popular science and sightseeing display to efficient, green and scientific production of crops, it provides guarantee. One of the reasons is that the current open-air cultivation of vegetable and flower products will face more air pollution, rainwater pollution, and insect pests. The glass greenhouse provides a good micro-environment climate for its production. The second is that the people engaged in agriculture are gradually aging. In the future, we must liberate the productive forces and use mechanized equipment to train agricultural industrial workers. This is a problem that my country's agriculture will inevitably face in the future.
The flower glass greenhouse is a building covered with glass materials. The building adjusts the shading system, ventilation system, ventilation system, cooling system, and heating system of the greenhouse through the instructions issued by the control system to the power distribution cabinet to achieve the most suitable growth of plants in the greenhouse Temperature, light, water, steam, fertilizer and other conditions.
1. Shading system
The shading system is divided into external shading system and Baidu internal shading system. The sunshade system is driven by the drive system to open and close the sunshade net to block excess sunlight from entering the shed. Among them, the Dutch greenhouse generally does not install an external shading system, but spray some shading paint on the top of the glass greenhouse in summer.
2. Ventilation and cooling system
The ventilation cooling system is divided into a natural ventilation system and a forced cooling system with fan water curtain. Natural ventilation mostly uses a top-opening system. The forced ventilation cooling is to extract the hot indoor air through a fan, and then the outdoor air enters the room after cooling down through a water curtain.
Three, water and fertilizer integrated machine
The fertilizer requirements and characteristics of the water and fertilizer integrated machine, the mixed fertilizer solution and irrigation water are fed through the pipeline system for water supply and fertilizer, and it is evenly and accurately transported to the root area of the crop. Water and fertilizer are supplied through a controllable pipeline system. After the water and fertilizer are dissolved, drip irrigation is formed through the pipeline and dripper, which is uniform, timed, and quantitative to infiltrate the growth area of crop roots, so that the main root soil is always loose and suitable for water content. At the same time, according to the characteristics of fertilizer requirements of different crops, soil environment and nutrient content conditions; crops need water during different growth periods, and the law of fertilizer requirements are designed for different growth periods, and water and nutrients are fixed and quantified, and directly provided to crops in proportion.
The flower glass greenhouse is a modern agricultural facility that integrates the main building, control system and planting technology of the greenhouse. It is the development direction of mechanized facility agriculture. At present, the flower glass greenhouse construction will also face the problem of high energy consumption in winter and major investment in the early stage during the use process.
