Study On The Change Of Environmental Factors In Newly Built - End Energy - Saving Sunlight Greenhouse

Dominant in sunlight greenhouse in facility agriculture, the region with the local superiorgeographical environment, developing and building energy-saving sunlight greenhouse, peopleuse it to obtain the larger income. In the Heilongjiang area,in view of the solar green house inwinter night temperature is too low,the winter production of poor lighting conditions,unevendistribution,the relative humidity inside greenhouse high easily lead to disease occurrence andspread,it is difficult to meet the crop growth needs,heat preservation cover material is difficult torealize automation control problems.Daqing has introduced a new type prefabricatedenergy-saving solar greenhouse, the greenhouse overcomes the weaknesses of the traditionalgreenhouse light and temperature distribution is not uniform, and the thermal insulation quiltstraw problem, damp proof effect is not good, solve the problem of the heat storage of solargreenhouse,realize factory production, installation of solar greenhouse parts standardization ofassembly.Taking Daqing ordinary greenhouse control,Tested the winter in December2014-March2015, model greenhouse and change in control room temperature in greenhouse things, thenorth-south direction and distribution,the distribution of soil temperature change and change innorth south direction in different soil soil temperature;measurement of winter greenhouse andcontrast experiment in greenhouse overall changes and distribution of light intensity,differentspan light intensity variation and distribution;and measurement under different weatherconditions in winter, sunny, cloudy and snowy day, new type of greenhouse and controlledgreenhouse indoor relative humidity changes.The results show that:1. New greenhouse can keep the indoor temperature in more than12℃at night,in things, latitudinal direction uniform temperature distribution, plant growth andtidy,2~3℃higher than that of control greenhouse indoor temperature,a new type of greenhousein against rain, snow, wind, fire and other natural disasters is superior to the control ofgreenhouse.2.Experiment in greenhouse soil depth for the area of more than60cm, Mark Twain is higherthan the control of the greenhouse, night soil depth of10cm,30cm,60cm in the averagetemperature5.7℃,4.0℃and2.7℃. 3.New greenhouse cultivation space is large,good lighting,roof lighting angle up to41.5degrees,the control of greenhouse lighting angle of25.2degrees,a new greenhouse than controlgreenhouse daylighting rate5.3%.4.new greenhouse indoor air relative humidity is stable than control in greenhouse,ventilatedeffect is better than the control in greenhouse.
