Also known as Cangxi Sydney or Shi Jia Pear. Originally from Cangxi, Sichuan, it is widely cultivated in Sichuan, with a small amount cultivated in Shaanxi and Hubei.
The fruit is large, weighing 300 ~ 500 grams, oval or gourd-shaped. Yellow-brown, with grayish brown spots, large and sparse fruit points. Peduncle slender, without calyx. 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.
Fruit ovoid or slightly oblate, persistent calyx, brown peel. The average body weight 196g is generally above 25Og in Jiangsu. The flesh is white, dense and crisp, and the juice is sweet. The content of soluble solids in the old road area of Jiangsu Province is 12.4%. 65438+ 10 ripens at the beginning of October and is storable.
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.
(3) the twentieth century
Originally from Japan. China's Liaoning, Beijing, Shanghai, Jiangsu, Zhejiang and other places have a small amount of cultivation, and many places in the northwest have also introduced.
The fruit is large, with an average weight of 135g. Most of them are nearly round. When ripe, it is yellow-green, and the fruit stalk connects the fruit, which expands into meat and has a beautiful appearance. The flesh is white, crisp, sweet, juicy, with few stone cells, and the quality is above average or superior. Shanghai ripens from late July to early August and cannot be stored.
Medium or weak growth potential, sparse branches, semi-erect, small crown, suitable for close planting. Generally, it begins to bear fruit in 3~4 years, and the early yield is high. The fruit setting rate is high. It is mainly the result of short fruit branches and short plant life.
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.
