Abstract: Experiments were carried out at Dayi and Qionglai county in Sichuan Province during 1992-1994, and the variety characteristics and technologies of increasing yield for Jinmi plum were studied. The results showed that:Jinmi plum belonged in Prunus Salicina Lindl, Prunus Linn of Rosaceae. Its characteristics were big fruit, high yield, excellent fruit quality, and good resistance of enviroments. The yield per tree had increased 46% by soil management. After adequate fertilizing the fruit weight had increased 4.6-6.4% and the yield 81.4-151.2% higher than control. The yield was raised 62.1% by spraying 20 ppm 2, 4-D and 0.2% KH₂PO₄ during full flowering and fruit growing. Therefore good managing soil and adequate fertilization as well as spraying growth regulator were main technologies for high yield of Jinmi plum.
