安丘蜜桃结果习性研究

Study on the Fruiting Habit of Anqiu Nectarina

为了为实施改善果实品质的技术措施提供依据,对与安丘蜜桃果实品质有关的结果习性进行了研究。研究表明:安丘蜜桃开花从4月4日开始,4月13日结束,初花期在4月7日,盛花初期在4月9日,盛花盛期在4月10日,盛花末期在4月11日。不完全花占5.42%,完全花占94.58%。自花授粉坐果率为91.49%。自然授粉坐果率为92.38%。生理落果有3次,第一次在盛花期后5天~14天,第二次在盛花期后20天~35天,第三次在盛花期后60天~70天。至果实成熟总坐果率为81.60%,落果率为18.40%。

In order to provide technical basis for improving the quality of fruit,the fruit habit related to the fruit quality of Anqiu nectarina was studied. Research shows: Anqiu nectarina blooms from April 4th to April 13th; the first flowers appear on April 7th; flowering period from April 9th to April 11 th. Incomplete flowers account for 5. 42%,and complete flowers account for 94. 58%. The self pollination fruit set rate was91. 49% and the rate of fruit set by natural pollination was 92. 38%. It drops fruits physiologically 3 times:the first happens in 5 ~ 14 days after flowering; the second happens in 20 ~ 35 days after flowering stage; the third happens in 60 ~ 70 days after the flowering. Before fruit maturity,the total fruit rate is 81. 60%,and dropping rate is 18. 40%.
