摘要
‘兰丁3号’为酸樱桃和中国樱桃远缘杂交所得。为乔化砧木,与常见品种嫁接亲和性好,根系发达,断根后易产生根蘖。其嫁接树分枝能力较强,定植后一般4~5年可进入盛果期。与乔化砧木‘兰丁2号’相比,其长势略强,‘先锋’/‘兰丁3号’定植后第4年,新稍数量、株高、干径、冠径均高于‘先锋’/‘兰丁2号’。第6年平均单株产量达到26.0 kg,为‘先锋’/‘兰丁2号’的1.63倍。
A new sweet cherry rootstock cultivar‘Landing 3’was derived from interspecific hybrids of sour cherry(Prunus cerusus)and Chinese cherry(Prunus pseudocerasus).It has very good grafting compatibility with most sweet cherry cultivars.It is a vigorous rootstock with developed root system and it easily produces sucker after root cutting.It can promote branching of grafting tree.The fully yields of grafting trees can be reached after planting 4–5 years.The grafting tree of Van/Landing 3 is slightly stronger than that of Van/Landing 2.The number of new shoots,tree height,trunk diameter and crown diameter of Van/Landing 3 are higher than those of Van/Landing 2 in the 4th year after planting.The average yield of Van/Landing 3 is up to 26.0 kg per tree in the 6th year after planting,which is 162.5%of the yield of Van/Landing 2.
