摘要
采用概率统计、相关统计、线性变化趋势、图标对比等方法,对宁夏平罗县气象站1999—2018年近20年4月份平均气温、最低气温、晚霜冻结束日期、大风和沙尘(暴)出现日数、日照时数、6月份最高气温等气象资料进行分析,结果表明:近20年来平罗地区春季气温回升速度明显加快,气温明显偏高,大风、沙尘(暴)天气日数减少,晚霜冻结束日期提前,降水增多,日照充足。同时,根据甜西瓜的生理特点以及其在不同生育生长期对气象条件的要求等因素,得出甜西瓜错季节种植的可行性结论。
The meteorological data from 1999 to 2018 at Pingluo Meteorological Station were analyzed such as average temperature,minimum temperature in April,late frost end date,days of strong wind,dust(storm),sunshine hours and the maximum temperature in June,by using the methods of probability statistics,correlation statistics,linear trend of change and icon comparison.The results showed that in the past 20 years,the spring temperature in Pingluo area increased rapidly,the temperature was obviously higher,the days of gale and dust(storm)decreased,the date of late frost freezing advanced,the precipitation increased,and the sunshine was abundant.According to the physiological characteristics of melon and the requirements of meteorological conditions in different growth stages and other factors,the feasibility conclusion of wrong planting of melon was drawn.
