利用树罩改变红星苹果(Malus clomestica Borkh)树周围的温度;并且确定:4月2、15日和5月7、22日等4个开花期.据可溶性固形物、含酸量、硬度和叶绿素的测定表明,花期提早与花期正常的果实相比,前者从开花到果实成熟的时间较长,延迟开花的果实所积累的可溶性固形物,低于花期正常或花期早的果实.果实最后体积随每次花期的推迟而减少。两个花期早的果实,明显地在呼吸高峰前期的最低限之前采收;而延迟花期的果实,则在呼吸高峰开始以后采收。贮藏中果实硬度的降低,随采收的推迟而增加。与其说贮藏期虎皮病和果实的绿色,与生长期的长度有关,倒不如说与采前的夜间温暖和有关。
Tree shrouds were used to change the temperature around the Malus clomestica Borkh tree and four flowering periods were confirmed, April 2-15 and May 7-22, etc. According to soluble solids, acid content, hardness and chlorophyll The results showed that the earlier the flowering period was from the flowering to the ripening, the soluble solids accumulated in the delayed flowering fruit were lower than the normal flowering or early flowering fruit.The final volume of the fruit Each flowering postponed and reduced. Two earlier flowering fruit, apparently harvested before the minimum of the pre-peak period, while the late flowering fruit is harvested after the respiration peak begins. The decrease in fruit firmness during storage increases with the delay in harvesting. Not so much the storage period of tiger skin disease and fruit green, and the length of the growth period, but rather as the night before and before the harvest and warm.
