Application of Temperature and Humidity Recorder in Greenhouse

温湿度记录仪 ,并且大棚中还有很多窗,通过观察 温湿度记录仪 显示的湿度,进行调节窗户的大小。 When we walked into the agricultural greenhouse , we can obviously feel that the temperature is much higher than the temperature outside the greenhouse. A temperature and humidity recorder is installed on the support wood in the greenhouse, and there are many windows in the greenhouse. Humidity recorder displays the humidity to adjust the size of the window. They explained that this was done primarily to control moisture. The need for ventilation and the need for temperature and humidity , etc. At this time, the teacher of the Agricultural University told them the secret.

According to our understanding of the situation, this village is mainly because of water problems. The greenhouse vegetable planting technology that has only been tried in the past two years, and the village committee has specifically found the Water Resources Management Bureau for this matter. With the support of the Authority, Jiuyan Jijing has been put into use, which has provided favorable conditions for the development of greenhouse vegetables . Some villagers who have not planted said that they saw the income of farmers growing in greenhouses increase, and they also plan to start planting greenhouse vegetables. With the popularity of greenhouse farming this year, reports from Dengpeng Planting that have improved farmers' living standards can be seen from the ⎝⎛优德w88体育网⎞⎠. Of course, in the middle of these things, it is also inseparable from such scientific and technological means. The use of temperature and humidity recorders and temperature and humidity monitoring systems to achieve Dapeng thermal insulation and humidity reduction to increase crop yield.

In greenhouse cultivation, the adjustment of meteorological parameters in the shed is an important factor affecting crop growth and yield. People need to adjust the deadline parameters in the shed regularly. The temperature and humidity meteorological parameters in the greenhouse are directly related to physiological factors such as plant respiration, root absorption, and transpiration, so how to scientifically adjust the temperature and humidity parameters is a question of our relationship.

Insulation dehumidification is the key to greenhouse vegetable cultivation. At present, some greenhouse vegetables are growing seedlings, and some have entered a critical period of growth. It is necessary to regulate the greenhouse environment. For seedling raising, it is very important to improve the insulation performance of the greenhouse, and it is necessary to reduce humidity under the premise of heat preservation. If conditions permit, use electric heating wire for heating; if the conditions are not enough, multi-layer covering method can be adopted to ensure that the temperature in the night shed cannot be lower than 18 ℃. To take advantage of fine weather, open the small door of the greenhouse to ventilate. When the weather is cold, you should choose to open the downwind outlet, and try to choose the time when the temperature is higher. In addition to ventilation and dehumidification, some ash, fine soil, etc. can be sprinkled in the shed to absorb moisture.

For strawberries and lettuce in the greenhouse, two layers of cover should be used for heat preservation, that is, the middle film is hung inside the greenhouse film. In order to achieve a good thermal insulation effect, the greenhouse can be covered with grasshoppers, etc., to reduce the blow of cold wind and heat dissipation. In the low-temperature stage of vegetable growth, spraying antifreeze or foliar fertilizer on the leaves can play a role in preventing cold and freezing, and maintaining flowers and fruits.

In summary, the adjustment of the temperature and humidity in the greenhouse is very important, so we need a suitable temperature and humidity recorder installed on the support frame in the greenhouse, and such a temperature and humidity recorder must be displayed with high-precision data measurement and display So that we can provide a scientific reference. Generally, the company's temperature and humidity recorder can pass the identification of the quality and technical supervision and inspection institute directly. We can use the data of the temperature and humidity recorder and the historical measurement data for a scientific comprehensive analysis, and the historical temperature and humidity data can be the next year. Provide references for plant growth.
