Light Management and Temperature and Humidity Management of Greenhouse

1. Light management and temperature and humidity management. In the early spring greenhouse pepper cultivation, because of the relatively simple temperature change after the pepper seedlings are planted, we are still a low one, and the humidity has a greater impact and insufficient light time. These important factors Research is not conducive to the cultivation of hot peppers in greenhouse in early spring. Therefore, teachers should pay attention to the management of different light environment and temperature and humidity data after the planting staff have completed their studies. Five to seven days after the pepper seedlings are planted, the greenhouse should be closed in time to ensure that the temperature in the greenhouse is basically maintained at about 30°C. At night, the temperature level is low, so it is necessary to analyze the multi-layer network coverage at night to ensure the temperature in the greenhouse to prevent pepper seedlings from being damaged. In the daytime, you must uncover the multilayer covering for light transmission, and increase the pepper planting greenhouse in an appropriate way The sunlight can increase the ground temperature in the greenhouse.

The method to reduce the heat conduction of some parts of the greenhouse to the outside, causing the heat loss of the cold bridge, is to try to block the cold bridge path that conducts heat to the outside, and the other is to take special measures at the cold bridge that conducts heat to the outside. The thermal insulation structure measures. In the design and construction of greenhouse, attention should be paid to issues such as gutter insulation, foundation insulation and external hole insulation. The greenhouse gutter has the function of connecting the roof and collecting rainwater and drainage. Most gutters are made of steel or alloys, which have poor thermal insulation performance and large heat loss. Relevant studies have shown that the gutter occupies less than 5% of the greenhouse area, but the heat loss is more than 9%. Therefore, the effect of the gutter on the energy saving and heat preservation of the greenhouse cannot be ignored. At present, the method of gutter insulation is to use hollow structural materials instead of single-layer metal materials and use an air interlayer to insulate the gutter; the second is to paste a thermal insulation layer on the surface of the single-layer material gutter.

The company also has a well-known domestic agriculture, and can help you solve the problems encountered in the planting process at any time. And it has close contact with vegetable vendors across the country to provide you with vegetable market information in a timely manner, solve the problem of difficult sales, and eliminate the worries of growers. By choosing Yeli Greenhouse Engineering Co., Ltd., you have not only chosen a greenhouse construction company, but more importantly, you have enjoyed a complete agricultural service system.

It can be seen that, as a new form of comprehensive land use, photovoltaic smart greenhouse are the product of the close integration of modern agriculture and clean energy, which not only saves land, does not change land attributes, but can also use space in three-dimensional ways to generate clean electricity. Expanding the proportion of renewable energy in power supply will bring two-way benefits. The construction of photovoltaic smart greenhouse can also promote green agricultural production and realize technologically efficient circular ecological agriculture. For urban areas, the photovoltaic greenhouse project can be built into a modern agricultural demonstration and education base, integrating agricultural activities and technological demonstrations, giving play to the industrial cluster effect, prospering the regional economy, and building a model and window for provincial and municipal characteristic agriculture.

The management of the greenhouse has a certain scientific basis, and the production effect can only be achieved by operating in the correct way. There is also great attention to wind protection in the greenhouse. The general principle is that the greenhouse will open the grass curtain in the morning, but do not let the wind out within an hour after the grass curtain is drawn. So why? Because after the grass curtain is covered at night, there is no light, and the vegetables in the greenhouse stop photosynthesis, but the respiration is always going on, which releases a lot of carbon dioxide, and the soil contains a lot of microorganisms, which will also decompose organic matter. Carbon dioxide is produced. After one night, a lot of carbon dioxide will accumulate inside the greenhouse, which is much higher than the concentration of carbon dioxide in the outside atmosphere. When the grass curtain was opened the next morning, the sun began to shine, and green plants such as vegetables began to photosynthesize, requiring a lot of carbon dioxide. At this time, the concentration is high, just enough to give vegetables sufficient raw materials, which will be transformed into photosynthesis. The nutrients are stored in vegetables.

Main business: greenhouse construction, greenhouse design, greenhouse engineering, greenhouse construction, greenhouse. He has extensive experience in greenhouse engineering design and has strong engineering construction capabilities. With a professional installation and construction team, quality assurance and reasonable price are well received by customers. The company has always pursued the service tenet of “service first, reputation**”.

2. After weeding and topdressing techniques work on pepper seedlings, the cultivation can make the soil pass through the soil, or the soil can be cut off, and the soil moisture and moisture can prevent weeds and pepper seedlings from affecting peppers The growth of seedlings. Degumming can also help fertilizer and increase the contact area between seedling roots and fertilizer to promote the absorption of pepper seedlings. When working with weeds, please pay attention to protecting the roots of pepper seedlings. This is suitable for places where the roots are far away from the roots of the seedlings and shallower closer to the roots of the seedlings. According to the growth of seedlings, shrubs are also needed to prevent the growth of pepper seedlings. The cultivation is generally about 5 cm. Chili peppers grow more frequently in the spring. Therefore, we must pay attention to promptly promote work. The fertilization work time is usually fertilization, when the seedling is in progress, after the fruit, after the fruiting period, every time you will be TOPDD once, make sure that the fertilizer needs pepper seeds.

In addition, the application of high-reflectivity spray paint and the large area of ​​the large side surface of the rectangular tube make the light of the greenhouse about 10-15% higher than that of the ordinary greenhouse. Under the action of the rectangular steel tube, the supporting force and compression resistance of the arch The intensity has been improved, even in heavy snow and heavy snow scenes, there is no fear, which is very common in the northeast and northwest regions. It is easy to form and is conducive to standardized production. This structure is suitable for large facilities, agricultural parks and sightseeing agricultural parks. Due to the reflection effect of the rectangular welded pipe, the absorption rate is effectively reduced. When the sun is hot in summer, the temperature is third lower than that of the greenhouse arch surface of the ordinary steel structure arch. It has a good protective effect on the shed film and prolongs the service life of the shed film.
