摘要
经过3年(次)连续进行春、夏、秋季芽接开心果的试验,结果表明:夏季接活率比春季高18.0个百分点,比秋季高42.7个百分点;春季接活率比秋季高24.7个百分点,秋季接活率仅为34.0%。夏季芽接后到成活需要8d,春季需要半月,秋季所需更长。夏接可比春季多繁育1/3倍的果苗,比秋接多1.25倍;春接比秋接多2/3倍。以夏接为主、春接次之繁育开心果,可早接多育果苗,扩大栽植开心果面积,加快开心果示范园的建设步伐。
The experiment was conducted on budding of Pistacia vepa for three years in spring,summer and autumn,the results showed：budding survival rate was 18.0% higher in summer than in spring and 42.7% higher than in autumn;budding survival rater was 24.7% higher in spring than in autumn,budding survival rate was 34.0% in autumn.Pistacia vepa needs 8 days from budding to survival in summer,however,the time was half of the month in summer,and the time was longer in autumn.Breeding Seedlings of Pistacia vepa in summer was 1/3 times more than in spring,and was 1.25 times more than in autumn;breeding seedlings of Pistacia vepa in as 2/3 times more than in autumn.Breeding of Pistacia vepa often occurred in summer and second was spring,spring through early budding and more seedling of Pistacia vepa,enlarge planting area of Pistacia vepa,to speed up step of demonstration garden construction of Pistacia vepa.
