摘要
1985～1989年对红星苹果树生产性能进行了研究。结果表明,红星苹果座果率较低的主要原因是花器结构特殊造成的,不利于授粉受精过程的进行,败育花率高。其次才是花期营养。同时表明,红星苹果花期要求温度较高,低温严重影响座果。红星苹果在盛果期的合理负载量应控制在每平方厘米干径0.30～0.35公斤时大小年幅度小,果实品质好。
The study was focused on productive properties of starking tree. The result showed that the primary reason that lower percentage fruit setting were special flower structure, and secondary reason was nutrition flowering period. The flowering period need higher temperature. The fruit setting was reduced on lower temperature. The reasonable bearing quantity was 0.30—0.35kg per cm^2 stem.
