摘要
1975～1985年,在辽宁西部前所果树农场进行红星苹果矮化中间砧试验研究。中间砧有 M 系的2,4,5,6,7,9,11、16,还有丹麦道生、保加利亚18号及甜黄魁。以山定砧嫁接苗作对照。经过10年试验,对其抗寒性、抗风、嫁接亲和力、开花株率、花序座果率,平均株产、树高、树冠体积、根系生长状况及分布、各砧穗组合的丰产相关指标进行了调查研究,并对各组合在前所果树农场自然条件及管理水平情况下的表现特点作出评价。
For the purpose of dwarfing the Red Delicious apple tree,from 1975
to 1985,experiments were conducted on Qianso State Fruit Farm in the
southwestern part of Liaoning Province,by grafting the scion on clonal
interlocks M_2,M_4,M_5,M_6,M_7,M_9 M_(11), M_(16),Denmark Doucine,Bulga-
ria 18,and Sweet Yellow Transparant,with the Malus baccata seedling
as basal rootstock.The length of the interstock was 20 era.The trees were
planted in the spring of 1975.Each combination included 5-13 trees.
During ten years of experiment,winter hardiness,wind resistance,the
compatibility of Red Delicious with interstocks,percentage of flowering
plants,fruit set of flower clusters,mean yield per tree,tree height,crown
volume,root distribution in the soil,and the high yield correlation index for
the Red Deliclous-interstock combinations were investigated.The charac-
teristics of different combinations were evaluated.
