广州地区澳洲坚果一年主要抽生三次梢,以多年生枝和春梢为主要结果母枝,分别占43.1%和39.1%.结果能力以更梢母枝最强,平均每枝坐果3.0个,其次为多年生枝(2.0个).平均花坐果率0.22%.坐果数与结果母枝长度、粗度、粗/长比和叶片数无显著相关,与花序数和初始坐果数密切相关(R~2=0.7653).树冠郁闭条件极显著地减少初始坐果数.花后5周内落掉总花量的99%以上.幼果的另一个脱落高峰在花后第5至8周,主要是旺盛营养生长与迅速生长的果实的营养竞争所致.
Macadamia in Guangzhou mainly took three shoots a year, taking perennial branches and spring shoots as the main results, with 43.1% and 39.1% respectively. The results showed that the strongest ones were the more shoots with the average fruit number of 3.0, (2.0). The average fruit setting rate was 0.22%. There were no significant correlations between the number of fruit setting and the number of parental branches, the thickness, the ratio of length to length and the number of leaves. The number of inflorescences was closely related to the number of initial inflorescences = 0.7653). Canopy canopy closure significantly reduced the initial fruitsetting rate, which dropped more than 99% of the total flower within 5 weeks after flowering.The other shedding peak of young fruit was 5-8 weeks after anthesis, Nutritional growth and rapid growth of the fruit nutrition competition.
