【摘要】：利用麻城龜峰山杜鵑花海3個(gè)不同海拔高度和臨近區(qū)域自動(dòng)站連續(xù)2年觀測(cè)的氣溫和物候資料,結(jié)合前期物候資料,統(tǒng)計(jì)不同高度、不同時(shí)段和不同要素的氣象條件,結(jié)果表明:杜鵑花開(kāi)放的臨界溫度為日平均氣溫穩(wěn)定通過(guò)10℃,達(dá)到盛花期物候標(biāo)準(zhǔn)的積溫指標(biāo)為:1月1日起至盛花期前一日≥0℃活動(dòng)積溫大于等于730℃;3月1日起至盛花期前一日≥10℃活動(dòng)積溫大于等于450℃,對(duì)兩項(xiàng)積溫按不同高度、不同時(shí)間段進(jìn)行垂直遞減率計(jì)算并作相關(guān)分析,兩因子與花期的線性相關(guān)顯著。以兩項(xiàng)積溫作預(yù)報(bào)因子,建立從3月底到4月底,每隔5天一次的不同時(shí)段共7個(gè)花期預(yù)報(bào)方程。利用積溫指標(biāo)結(jié)合預(yù)報(bào)方程,可對(duì)杜鵑花期進(jìn)行滾動(dòng)預(yù)報(bào)和精細(xì)化預(yù)報(bào),預(yù)報(bào)效果與實(shí)況基本吻合,誤差較小。
[Abstract]:Based on the temperature and phenological data of three azaleas sea at different altitudes and adjacent areas observed for two consecutive years, combined with the previous phenological data, the meteorological conditions of different heights, different periods and different elements were calculated. The results showed that the critical temperature of azaleas blooming was that the daily average temperature passed through 10 鈩，
