Abstract: The systematic research was conducted on the Zhujiao No.11 fruit′s growth. The result shows that the Zhujiao No.11fruit′s growth present “S” type curvilinear motion , growing amount increase the parabola presenting type its day. It need about 63 days from blooming to ripe fruit, the greatest growing amount appears on the 19th day after the flower. The fruit gradually transform color to 58day after the flower, can gather physiology ripe fruit 64 day after the flower, 15~43 days are the growth period rapidly of fruit after the flower, it is the key period deter mining the yield . The plants should be added to organic fertilizer and adjusted measures, etc, in time with production . Make the fruit fully expand, help to increase the yield, gather the fruit in time according to market demand at the same time , coordinate the competition relation of nutrition, guarantee to get bumper yield and have a bumper harvest.
