摘要
为探寻新疆平欧杂种榛焦叶发生的主要原因,以2个平欧杂种榛主栽品种为研究对象,对焦叶发生程度、栽培环境因子进行测定,利用相关性和回归分析等方法探析环境因子与平欧杂种榛焦叶发生的相关性,以及对焦叶率影响较大的环境因子。结果表明:(1)在生长季内,C园平欧杂种榛没有焦叶现象发生,A园和B园焦叶发生均在9月达到高峰(焦叶发生率≥80%),此时2个品种焦叶发生程度均为‘新榛3号’大于‘新榛1号’,其中A园平均焦叶率分别为15.15%、6.75%;B园分别为:37.09%、33.2%(2)与焦叶率存在极显著相关性的环境因子包括:光照强度、温度、相对湿度、土壤含水量和速效钾(P<0.01)。(3)多元回归分析显示‘新榛1号’焦叶率受各环境因子影响程度从大到小依次为温度、相对湿度、土壤含水量、速效钾、光照强度;‘新榛3号’从大到小依次为相对湿度、土壤含水量、光照强度、速效钾、温度。
To find out the main reason of Corylus heterophylla×C. avellana L. scorch leaf in Xinjiang, two Corylus heterophylla×C. avellana L. cultivars were used as the research objects, by measuring the degree of scorch leaf occurrence and environmental factors, correlation analysis and regression analysis were used to analyze the correlation between environmental factors and the occurrence of scorch leaf in hazel hybrids and the environmental factors that had a greater effect on scorch leaf. The results showed that:(1)In the growing season, there was no scorch leaf in test garden C, the occurrence of scorch leaf in test garden A and test garden B reached the peak in September(The incidence of scorch leaf is ≥80%) at this time, the occurrence degree of scorch leaves of both cultivars was Corylus ‘Xinzhen 3’ >Corylus ‘Xinzhen 1’.(2)The environmental factors that are significantly correlated with the rate of scorch leaves including light intensity, temperature, relative humidity, soil moisture content and available potassium(P<0.01).(3)Multiple regression analysis showed that the scorched leaves rate of Corylus ‘Xinzhen 1’ was affected by various environmental factors in descending order of temperature, relative humidity, soil moisture content, available potassium, light intensity, and for Corylus ‘Xinzhen 3’, the descending order was relative humidity, soil moisture content, light intensities, available potassium, temperature.
