Last Updated: 2024/11/22, First, the morphological characteristics of the tree is strong, and the tree capital is more open. After happy shaping and pruning, the height of the 3-year-old tree is 260 cm, the stem circumference is 25 cm, and the crown diameter is 3 × 2.6 m. New shoots are green, annual branches are reddish brown, trunk and perennial branches are grayish brown. The leaves are dark green and smooth. Leaf gland reniform, small but inconspicuous. 2. Biological characteristics (1) the phenological period of flower bud expansion in the Yangtze River Basin is the first and middle of March, the full flowering period is from late March to early April, the florescence is 57 days, and the fruit is ripe in the middle and last ten days of July.

1. Morphological characteristics: strong tree vigor and relatively open tree capital. After open-ended pruning, the 3-year-old tree is 260 cm tall, 25 cm in trunk circumference and 3×2.6 m in crown diameter. The shoots are green, the annual branches reddish brown, the trunk and perennial branches grayish brown. Dark green leaves, smooth foliage. Leaf glands reniform, small and inconspicuous.

II. Biological characteristics

(1) The phenological period is in the middle of March, the flower bud expansion period is in the middle of March, the full flowering period is from the late March to the early April, the flowering period is 57 days, the fruit matures in the middle and late July, and the growth period is 100110 days.

(2) Growing and fruiting habits Young trees grow vigorously, new shoots branch many times, if combined with 23 times of topping, stable high-yield tree structure can be formed in the same year. After entering a large number of fruits, tree vigor tends to moderate, growth is stable, new shoots are stout, germination rate is high, branches are strong, and multiple flower buds are mostly. The fruit of young trees at the beginning of fruiting period is mainly long and medium fruit trees, and at the full fruiting period is mainly medium and short fruit trees, accounting for more than 76% of the total number of fruit trees. Natural pollination fruit set rate is high, strict thinning is needed to enlarge fruit.

(3) Early fruiting and high yielding young trees in Xinchuan Island are easy to flower and bear fruit early, with early fruiting and high yielding characteristics. The seedlings bear fruit in the second year after planting, with an average of 28 fruits per plant, weighing 7.3 kg; the yield of 3-year-old plants is 26.2 kg, equivalent to 1775 kg of 667 square meters; the yield of 4-year-old plants is 46.9 kg, equivalent to 3142 kg of 667 square meters.

(4) Adaptability This variety has strong adaptability and has good growth results under different soil conditions in Liaoning, Shandong, Zhejiang, Hubei, Sichuan, Yunnan and other provinces. It can be popularized in the north and south.
