2008年在通榆县兴隆山镇林场甜仁用杏‘龙王帽’生产园采种,2009年春季播种,2013年全部结果,从种子苗中筛选出2个甜仁优良无性系,优系‘23号’和优系‘24号’。结果表明:2个优系均具有早期丰产性好、抗寒性强。优系‘23号’单仁质量0.802g,出仁率38.74%;优系‘24号’单仁质量0.764g,出仁率42.44%,2个优系出仁率均高于‘龙王帽’(31.85%);以山杏幼树为砧木进行嫁接,第2年结果产量均超过‘龙王帽’,通过调查嫁接后生长量和长枝数量,发现2个优系新梢生长量比‘龙王帽’低,但长枝数量比‘龙王帽’多,并总结了2个优系的栽培技术要点。
In 2008 Tongling County Xinglong Shanzhen forestry sweet kernel apricot ’Dragon King hat’ production garden seed, sowing in the spring of 2009, all results in 2013, from the seedlings screened two sweet kernels excellent clones, excellent line ’23 No. ’and excellent system’ No. 24 ’. The results showed that both of them had good early yield and strong cold resistance. The quality of single kernel of No.23 was 0.802g and the kernel rate was 38.74%. The single kernel quality of No. 24 was 0.764g and the kernel rate was 42.44% (31.85%). Using the prunus armeniaca as the rootstock for grafting, the results of the second year all surpassed that of the ’Dragon King’. After investigation, the growth of the two excellent pruning shoots was higher than that of the ’Dragon King Hat ’is low, but the number of long branches than the’ Dragon King hat ’more and summed up the two gifted lines of cultivation techniques.
