摘要
以瑞雪/M26苹果砧穗组合为对照,研究了瑞雪/青砧1号苹果砧穗组合在生长、成花以及碳、氮养分吸收利用等方面的栽培特性。结果表明:瑞雪/青砧1号幼树强健,整齐一致,生长迅速,萌芽率高,成枝力强;根系对碳、氮养分的吸收贮藏能力均较强,茎对碳素吸收贮藏能力强但对氮素吸收能力较弱;叶片对氮素吸收贮藏能力较强;该砧穗组合幼树早花能力较弱,周年生长期长,秋季停长较晚。
The cultivation characteristics of Ruixue/Qingzhen 1 in growth,flowering,carbon and nitrogen nutrient absorption and utilization were studied compared with Ruixue/M26.The results showed that the saplings of Ruixue/Qingzhen 1 were strong,tidy and consistent,grew more rapid,with a high germination rate and strong branching ability.The root system had strong ability to absorb and store carbon and nitrogen nutrients,and the stem had strong ability to absorb and store carbon but weak ability to absorb nitrogen.The leaves have strong ability to absorb and store nitrogen;the young trees of this combination have a weak early flowering ability,long annual growth period and late autumn growth.
