摘要
研究了不同定干高度对瑞雪/青砧1号组合单干苗生长发育的影响。2024年春季,将刚定植的48株生长一致的幼树随机分为4组,进行不定干、130 cm定干、110 cm定干和90 cm定干处理,4月后,各处理每30 d调查1次生长发育指标,10月(秋梢停长后)结束。结果表明,定干高度显著影响树高、干径、枝类组成、中心干延长枝长度和粗度以及萌芽率和成枝率。130 cm定干处理在多数指标上表现最优,不定干处理次之,110 cm定干处理第三,90 cm定干处理第四。
This study investigated the effects of different trunk heights setting on the growth and development of single-stem seedlings of the Ruixue/Qingzhen 1 combination.In the spring of 2024,48 newly planted and uniformly growing young trees were randomly divided into four groups and subjected to no trunk height setting,130 cm trunk height setting,110 cm trunk height setting and 90 cm trunk height setting treatments.After April,growth and development indicators were surveyed every 30 days for each treatment,and the study was concluded in October(after the cessation of autumn shoot growth).The results showed that trunk height setting significantly affected tree height,trunk diameter,branch composition,length and thickness of the central leader extension,as well as bud break rate and branching rate.The 130 cm trunk height setting treatment performed the best in most indicators,followed by the no trunk height setting treatment,then the 110 cm trunk height setting treatment,and the 90 cm trunk height setting treatment ranked last.
