西宁市区番茄温棚的气象效应研究简

目的]研究西宁市区番茄温棚的气象效应。方法]利用2012年4月～2013年3月对温棚德福番茄开花一果实采摘发育期的观测资料和同期温棚内外的气温、地温、湿度的观测资料，对青海省西宁市区番茄温棚的气象条件效应进行分析。结果]西宁市区番茄温棚气象效应显著，气温、地温、湿度日变化效应依次为1、11、4月，7月最小，季节依次为冬季、秋季、春季、夏季，比温棚外冬季气温提高13．9～25．9℃、湿度提高13％～40％、地温提高16．1～22．8℃，夏季气温提高4．9～7．6℃、湿度提高O％～t1％、地温提高1．8—8．8℃；年变化比温棚外气温提高2．O～21．4℃、地温提高5．1～34．3℃、湿度提高2％～54％。结论]该研究为西宁市区特色设施农业的大面积推广发展提供科学依据。

Research on the Meteorological Effect of Tomato Greenhouses in Xining Urban

Objective ] The research aimed to study the meteorological effect of tomato greenhouses in Xining urban. Method] Using the ob- servational data of flowering - fruit picking of Dove tomato greenhouses and the air temperature, ground temperature ana humidity conditions of greenhouses inside and outside in the same period from April 2012 to March 2013, the meteorological effect of tomato greenhouses in Xining urban were analysed. Result3 The meteorological effects of tomato greenhouses were significan in Xining. The sequence of diurnal variation effects of Temperature, ground temperature and humidity is in January, November, April, July smallest, followed by winter, autumn, spring, summer. The temperature raised 13.9 -25.9 ℃ than that outside greenhouses, humidity increased by 13% -40%, ground temperature en- hanced 16.1 -22.8 ℃ in winter, and in summer, the temperature advanced 4.9 -7.6 ℃, humidity increased by 0% - 11% , ground temper- ature improved 1.8 -8.8 ℃ ; Annual change of temperature increased 2.0 -21.4 ℃ than that outside greenhouses, ground temperature raised 5.1 -34.3 ℃, humidity increased by 2% -54%. Conclusion] The study provides the scientific basis for the large scale development of the special agricultural facilities in Xining.
