山茱萸同一花序中小花开放顺序是从边缘向中心依次开放,开放后第1～2天座果率最高。雌蕊可授期7～8d以上。异花授粉座果率最高。座果率与花期降雨量呈显著负相关,与气温呈正相关,每花序日开花数量与日照时数呈显著正相关。花期和生理落果期用B,TRIA,防落素,IBA,NAA喷施及拉枝和开甲等农业技术措施保花保果,效果显著而稳定。
The order of flowering of small flowers in the same inflorescence of dogwood is in order from the edge to the center, and the highest fruit rate is found in the first to the second days after opening. Pistils may be granted for more than 7 ~ 8d. Cross-pollination fruit rate is the highest. There was a significant negative correlation between fruit setting rate and flowering date and positive correlation with temperature. The number of flowering per day was positively correlated with the number of sunshine hours. The flowering and physiological deciduous period with B, TRIA, anti-litter, IBA, NAA spray and pull branches and open armor and other agricultural techniques Paul flower and fruit protection, the effect was significant and stable.
