摘要
为了探讨、揭示干旱胁迫对沙棘生育与产量形成因子间的关系。本文采用田间调查与室内实验分析相结合。结果表明沙棘单株生育与产量关系受干旱胁迫影响最大,造成植株生长势衰弱与减产。沙棘产量的形成,决定于植株生长势、水分利用效率、根系贮水能力、果枝数、座果率。
The paper explores and reveals the factor relationship between drought stresses on seabuekthorn fertility and output. Combined investigations in field and laboratory analysis, the results is that seabuckthorn plant fertility and output are serious affected by drought stresses, which can make seabuekthorn plant growth slow and output reduced. The paper concluded that seabuckthorn output is decided to plant growth potential, water use efficiency, water storage capacity roots, a few fruiting branches, fruit rate.
