The flesh is white and crisp, the juice is sweet, the stone is small, and the quality is above average. It ripens from late August to early September and can be stored until 1 ~ February of the following year.

After 3~4 years of planting, the yield is high, mainly short fruit branches, but the long fruit branches and axillary buds have weak fruiting ability.

Suitable for cultivation and close planting in warm and humid areas. Weak wind resistance and pest resistance.

② Late Shan Zhi.

It is a late-maturing variety in Japan, widely cultivated in the middle and lower reaches of the Yangtze River, and now it is also well cultivated in Minhe, Qinghai, Zunhua, Hebei and Weihai, Shandong.

Drought and waterlogging tolerance, cold tolerance, scab resistance, and sensitivity to ring rot and black spot. A great demand for fertilizer. It is necessary to maintain strong flower buds and control the number of fruit-setting, otherwise the fruit will be small and the tree will be premature.

It has a wide adaptability and performs well in Shanxi, Ningxia and Xichang, Sichuan, and also in Korla to Aksu, Xinjiang, but it shows weak trees and small fruits in the red soil hills of southern Jiangsu and Jiangxi. Strict requirements on fertilizer, water and cultivation conditions. Ningxia has moderate cold resistance, and its flower buds are easy to freeze but strong in toughness. Weak wind resistance, weak resistance to rot, black spot, ring rot and scab.
