摘  要:为探明核桃二次枝的作用,以新疆温宿县两个主栽核桃品种‘温185’和‘新新2’为研究对象,观测了常规栽培核桃二次枝和一次枝混合芽成花与结实特性。结果表明,这两个品种二次枝的开花时间、花序类型与数量、坐果与果穗类型、果实主要营养品质特性与一次枝的相关特性无显著差异(P>0.05),生产中可以根据核桃树生长发育特征和二次枝生长特征,合理保留二次枝,利用二次枝培养树形,通过修剪控制其生长并促进结果,提高核桃产量。In order to explore the function of secondary shoots of walnut,' Wen 185’ and ‘Xinxin 2’ in conventional cultivation were taken as the experiment materials in this paper, and their and fruit setting on mixed buds of secondary shoots and primary shoots of walnusults showed that there were no significant differences in their blooming phenoand quantity, fruit setting and ear types and the major nutritional quality characters between secondary shoots and primary shoots of 4 Wen 185’ and ^Xinxin 2’. According to the characteristics of growth and development and the growth characteristics of the two branches of walnut trees , the secondary shoots can be retained reasonably for cultivating tree form structure and controlling its growth by p rcreasing the fruit yield.
