观察了２次结实板栗２次花原基形成与分化的进程，同时对其叶片中的Ｎ、Ｐ、糖营养周期变化动态规律作了研究。结果表明，其第１次花原基形成基本与一般中国栗品种类似，而第２次混合花原基形成及分化虽同样要经历４个过程，但时间相对较短，且其混合花原基形成的极限时间为５月底至６月初，试验研究结果同时表明，２次结实板栗树体营养周期可分为休眠期、营养消耗１期、营养积累１期、营养消耗２期、营养平衡期、营养积累２期共６个时期，其中板栗雄花序数量是其树体营养消耗量的主要因素。 The formation and differentiation of the second flower primordia were observed in two times of strong chestnut. The dynamic changes of N, P and sugar in the leaves were also studied. The results showed that the formation of the first flower primordium was similar to that of the common Chinese chestnut. However, the formation and differentiation of the second flower primordium also went through four processes, but the time was relatively short, and the flower primordium The formation of the limit of time from the end of May to early June, the results of the pilot study also showed that 2 times the chestnut tree nutrition cycle can be divided into dormant period, a nutrition consumption, nutrient accumulation 1, nutrition consumption 2, nutrition balance period, There were 6 stages of nutrient accumulation in stage 2, in which the number of chestnut male inflorescences was the main factor of tree nutrition consumption.
