- W1562093668 abstract "以4 年生富士/SH40/八棱海棠为试材,研究了过量灌溉条件下起垄栽培对富士苹果生长和 15 N-尿素利用、 分配的影响。结果表明,过量灌溉条件下,与平栽处理相比起垄栽培处理在春梢停长期根系的超氧化物歧化酶(SOD)和过氧化物酶(POD)活性分别提高1.70倍和1.69倍,根系游离脯氨酸含量降低了63.60%,根系活力和细根生长量分别提高1.44倍和1.68倍; 在秋梢停长期也表现出相似规律。起垄栽培与平栽处理在春梢停长期树体的氮素利用率分别为4.40%和3.86%,差异不显著; 到秋梢停长期分别为5.16%和4.02%,差异达显著水平。起垄栽培植株营养器官 15 N 分配率均高于平栽,其中以细根最为显著,且随物侯期的推移差异越明显。" @default.
