Greenhouses are light-harvesting buildings, so there is a need for good light transmission when creating greenhouse greenhouses. Light transmittance is one of the most basic objectives for assessing greenhouse light transmission. The greenhouse transmittance is affected by the light transmission function of the greenhouse and the shadow of the greenhouse.

Greenhouses are light-harvesting buildings, so there is a need for good light transmission when creating greenhouse greenhouses. Light transmittance is one of the most basic objectives for assessing greenhouse light transmission. The transmittance of the greenhouse is affected by the light transmission function of the greenhouse and the shadow rate of the greenhouse skeleton, and it is different from the viewpoint of the solar radiation at different times. The transmittance of the greenhouse is also changing at any time. Therefore, greenhouse light transmittance is a key factor affecting crop growth. The following is a brief introduction by the staff of Jinyi Greenhouse.

The most important thing in greenhouse greenhouses is the insulation function of greenhouses. How to reduce energy consumption and improve the heat preservation function of greenhouses is the most direct way to improve the efficiency of greenhouse production. The greater the insulation ratio, the better the insulation function of the greenhouse. Greenhouse construction also needs to consider its durability. Greenhouse durability is affected by factors such as the aging resistance of greenhouse data and the carrying capacity of the greenhouse main structure. In addition to its own strength, the durability of the light-transmitting data is still attenuated with the extension of the data, and the degree of attenuation of the light transmittance is the decisive factor affecting the service life of the light-transmitting data. As the greenhouse operates in a high temperature and high humidity environment for a long time, the appearance of the components will become one of the main factors affecting the service life of the greenhouse.

Greenhouse processing points

(1) It is best to use a soil moisture recorder in a greenhouse, which can record five parameters of soil temperature, soil moisture, atmospheric temperature, atmospheric humidity and dew point in real time. In this way, we can monitor and analyze the moisture of the soil in the greenhouse, which is more conducive to crop planting.

(2) Controlling humidity is one of the main points for handling glass greenhouse for vegetables in winter. Many farmers know that the humidity in the shed is 70% to 80%. However, because many hygrometers are not suspended in the shed, the farmers cannot accurately grasp the humidity in the shed, resulting in multiple diseases. Therefore, hygrometers should be hung in greenhouses, which is especially important for novice growers. When the humidity in the shed is too large, in addition to ventilation and dehumidification, it is also possible to apply grass ash to the ground for dehumidification.

(3) Some farmers apply nitrogen fertilizer at a dosage of about 1500 kg per hectare. The more fertilizer, the higher the output value, which is actually a waste of fertilizer and salt damage. Therefore, when farmers are planting in greenhouses, they should pay special attention to the problem of excessive fertilization.

(4) In the winter, the lack of illumination will become the main reason that affects the progress of vegetable output. Most farmers know that there are reflective curtains in the shed, but some of the reflective curtains are too low, and the vegetable plants simply block the light, resulting in poor performance of the reflective curtain. When hanging the reflective screen, the reflective curtain with a width of 1 to 1.2 meters should be hung in the local area of 1.7 meters high. Do not hang the back wall of the entire shed to prevent the heat stored in the back wall. Vegetables such as cucumbers and loofah, which require strong light, can be equipped with special fill light in the greenhouse to fill the light for 2 to 3 hours, and extend the time of the vegetables to promote the accumulation of organic matter in vegetables and improve the output value.
