温州蜜柑花后有两次明显的生理落果。第一次时值春梢抽发后新梢转绿期,落果高达总花量的80%以上。第二次在夏梢抽生期,落果相对较少。两次生理落果高峰的出现,似与柑桔抽生新梢而消耗养分有关。目前生产上广泛应用的抹除夏梢的措施,对减少第二次落果起到了较好作用。而对减少第一次生理落果,多采用激素保果,但效果不稳定。为寻求提高前期座果基数的措施,1980年我们在我 There are two obvious physiological drop fruit after the Wenzhou satin flower. The first time after the spring shoots shoot shoots turn green, drop fruit up to the total amount of more than 80%. The second time in summer shoot pumping period, the drop is relatively small. The appearance of two physiological drop-off peak appears to be related to nutrient consumption due to citrus fresh shoots. Currently widely used measures to erase summer shoots, to reduce the second drop played a better role. To reduce the first physiological drop, the use of hormone protection, but the effect is not stable. In 1980, we were looking for ways to improve the base of early fruits
