俄罗斯红穗醋栗S30生物学特性和扦插繁育技术研究

Biological Characteristics of Russia's Red Currant S30 and Cutting Breeding Technology

为丰富高寒地区小浆果树种,于2003年从俄罗斯引进优良红穗醋栗品种S30,连续7 a进行生物学特性和繁育技术试验研究。结果表明：红穗醋栗S30在黑河市能够正常生长发育,开花结实,属于晚熟品种。基生枝年高生长量为114.67 cm、径粗1.28 cm;高速生期在6月初至7月中旬,生量长可达50 cm,为全年的43.6%;径速生期在6、89、月之间。嫩枝扦插成活率高,可达93%,苗高17.2 cm,地径0.36 cm。2种硬枝扦插方法中覆盖地膜扦插苗木成活率高,为58%,苗高59.21 cm,地径1.01 cm,高速生期在7、8月,径速生期在7~9月间,苗床直接扦插苗年生长缓慢,苗高16.86 cm,地径0.63 cm。

In order to enrich the small berry tree species in alpine regions,took the fine red currant varieties S30 which imported from Russia in 2003 as materials,continuous 7 years studied their biological characteristics and breeding techniques.The results showed that red currant S30 in the introduction to the normal growth and development,flowering and seed,belongs to late-maturing varieties.Growth of basal branches high volume 114.67 cm,diameter crude 1.28 cm;high-speed health view in mid-July to early June,the health and volume grow as long as 50 cm,for the year 43.6%;Drive fast-growing period of three months in the 6,8,9.Softwood cuttings high survival rate up to 93%,seedling height 17.2 cm,diameter 0.36 cm.Hardwood cuttings are two ways to cover the plastic film cutting saplings high survival rate was 58%,seedling height 59.21 cm,diameter 1.01 cm,high-speed health view July to August,drive fast in the July to September period,the seedbed direct cuttings-year slow-growing,seedling height 16.86 cm,diameter 0.63 cm.
