摘要
通过分析 2 0 0 1、2 0 0 2年延安市日光温室内的温度资料 ,得出当外界气温达 - 2 0℃时 ,棚内温度可降至 0℃以下 ,棚内作物受冻害 ,据此确定了强低温天气和气象服务标准 ;结合延安市宝塔区 195 1～ 2 0 0 2年气象资料 ,分析了强低温天气分布特点及其对日光温室农业生产的影响 ,同时给出对策措施、建议和气象服务重点。
Through analyzing temperature data from a sunshine greenhouse in 2001 and 2002,it is discovered that when the environment temperature dropped to -20 ℃,the temperature in greenhouse will be 0 ℃ or less. Hereby,the standards of the strong low-temperature weather and meteorological service are determined. The characteristics of low-temperature weather and the effect on sunshine greenhouse agriculture are found out by means of the 52-year data from Baota district. In the meantime,some countermeasures and suggestions about meteorological service are given.
