采用多元统计分析方法对雷林1号桉杆插成苗率与气象因子的关系进行了初步研究．结果表明：不同月份的打插成苗率是不同的，5～8月较低．1～4月和9～12月均较高，尤以2月、3月和11月更高，分别为88．8％，90．1％和97．1％；成苗率与月均气温、月相对湿度、日最大降雨量、全月降雨天数之间存在显著的相关关系；这4个因子对成苗率影响程度由大到小的排序为日最大降雨量＞全月降雨天数＞月相对湿度＞月均气温． Multivariate statistical analysis method was used to study the relationship between eucalyptus plumbing rate and meteorological factors. The results showed that the percentage of inserted seedlings in different months was different, and it was lower in May to August. From January to April and from September to December, they were all higher, especially in February, March and November, which were 88.8%, 90.1% and 97.1% respectively. , Monthly relative humidity, daily maximum rainfall and monthly precipitation were significantly correlated. The order of influence of these four factors on the rate of seedling emergence was maximum daily rainfall> monthly rainfall days> month Relative humidity> monthly average temperature.
