Greenhouse vegetables grown without greenhouse thermometer

Greenhouse vegetables planting technology development, can say is a kind of trend, with the improvement of living standards, adjust the vegetable production season, adjust market demand to the diversification of vegetable demand will increase further, the vegetable greenhouses can make up for a lack of some seasonal vegetables, promote vegetables, high quality and high yield of vegetable production in the future will undoubtedly plays an important role. Greenhouse vegetables planting can promote the growth of vegetables, and to increase production and extend the supply and anti-season listed, the purpose of better economic benefit. Use of greenhouse vegetables, different species have different requirements for temperature, mix well and temperature regulation management is the key to good kind of greenhouse vegetables. Such as planting cucumbers, more strict to the requirement of temperature, the optimum temperature during the day for 24 & ndash; 26 ℃, the night of 14 & ndash; The lower limit of 15 ℃, low temperature is 10 & ndash; 12 ℃, the temperature is below 10 ℃ will stop growing, above 30 ℃ root activity is weak, leaves are shrinking. Seedling growth period not less than 18 ℃, minimum temperature of 20 & ndash; 23℃。 Such as tomatoes, like high temperature, 25 & ndash; Is the most ideal germination temperature 30 ℃. Growth is appropriate temperature is 27 ℃ during the day, 17 ℃ at night. Cultivation during the lower limit of ground temperature is 10 ℃, according to the growth of the lowest temperature is 5 ℃, 28 ℃, the optimum temperature for top shall not exceed 38 ℃. So without greenhouse thermometer greenhouse planting vegetables, MMG - 3 greenhouse thermometer has been the preferred thermometer, MMG - 3 a maximum and minimum thermometer, the product name: maximum and minimum thermometer, thermometer, greenhouse thermometer use areas: greenhouses, the meteorological department, specifications, such as description: models: MMG - Three types: structural style of the maximum and minimum thermometer: can flip eaves, circular button material: beige ABS shell shape size: 22 * 13 cm temperature range: - 40 - 50 c, red and black single calibration accuracy: + / - Packing: 1 c 100 shipping/box, 50 / box only four express delivery, the product characteristic: the maximum and minimum thermometer is used to record in a certain period of time the maximum temperature and minimum temperature in air five, maintenance notice: in use. Transportation. Storage should be upright, not from vibration so as not to cause of the use of mercury. Greenhouse vegetables production is affected by many factors, and the temperature is one of the most important, in the whole process of crops, different growth stage of its growth on temperature requirements are also different. So we in the use of vegetable greenhouse for vegetable, with reasonable temperature management for greenhouse thermometer, enhance greenhouse plant production.
