Is the disease-free tree evergreen or deciduous?

The disease-free son is native to the south of the Yangtze River Basin in China and Indo-China Peninsula, India and Japan. Nowadays, there are a lot of cultivation in Jinhua, Lanxi and other areas of Zhejiang, but not in other areas. So, is the disease-free tree evergreen or deciduous?

First, is the trouble-free child evergreen or deciduous

The disease-free tree is a deciduous tree, up to 20 meters high, with grayish brown or dark brown bark; twigs green, glabrous. It is commonly cultivated in temples, gardens and villages around the country. Like light, slightly resistant to shade, strong cold resistance. It is not strict with the soil and can withstand drought. The sprouting ability is weak and can not bear pruning. The growth is faster and the life is long.

Second, the method of disease-free reproduction.

1. Seedling cultivation

Reproduce with seeds. Harvest when the fruit is ripe in autumn, peel and clean the seed in time. Because the seed shell is hard, it can not only be sown in autumn, but also be buried in wet sand to overwinter and spring sowing. The nursery requires deep, fertile soil and good drainage. Soil preparation requires deep ploughing, adequate application of basic fertilizer and good drainage ditch.

Sowing on demand is appropriate, the density is row spacing 25 cm, plant spacing 12-15 cm, and the thickness of soil cover is 5 cm. 50 to 60 kg per mu of seeds, 10 to 12000 seedlings per mu, 60 to 100cm in height and 0.8cm in ground diameter. The disease-free son has fewer diseases and insect pests, and the focus is on the control of underground pests in the seed germination stage and longicorn beetles in the seedling stage.

2. Cultivation of large seedlings

Select a good nursery, apply sufficient basic fertilizer, and make a bed in the east-west direction, with a width of 1.5 meters and a height of 25 centimeters. From the defoliation of seedlings in autumn to the sprouting in the following spring, one-year-old seedlings with good tree shape, vigorous growth and no diseases and insect pests were selected and planted according to the row spacing of 60 cm × 80 cm. When raising seedlings and planting, we should protect the terminal buds and roots, and bring as much persistent soil as possible. After planting, do a good job of routine field management.
