辽宁南果梨气候品质评价技术方法及应用

Technical Methods and Application of Climate Quality Assessment of Nanguo Pear in Liaoning Province

基于南果梨发育期监测数据和区域气象站资料,根据南果梨生长发育对气象条件的需求,采用统计方法,确定了温、光、水等气象要素对南果梨品质影响评判指标。结果表明:南果梨气候品质评价模型由区域适宜性、不同物候期气象条件、气象灾害、生产管理条件共14个因子构成。影响南果梨品质的主要气象要素为各发育期气温、降水、日照,坐果期、果实膨大期、果实上糖期日较差;2018年辽宁鞍山海城王石镇天鹰果业生产的南果梨气候品质评分为89.6分,为"优"等级。

Based on the monitoring data of Nanguo pear in the development period and regional meteorological stations,according to the demand of meteorological conditions for the growth and development of Nanguo pear,by using statistical methods,the evaluation indexes of the influence of temperature,light,water and other meteorological factors on Nanguo pear quality were determined. The results showed that:(1) The climate quality evaluation model of Nanguo pear was composed of 14 factors,including regional suitability,meteorological conditions in different phenological periods,meteorological disasters and production management conditions. Among them,the main meteorological factors affecting the quality of Nanguo pear were temperature,precipitation,sunshine,fruit setting period,fruit expansion period and fruit sugar period in each development stage.(2)The climate quality evaluation score of Nanguo pear produced by Tianying Fruit Industry in Wangshi Town,Anshan,Liaoning province in 2018 was 89.6,which was the most“excellent”grade.
