White fruit is the fruit of the ginkgo tree.
White fruit, Ginkgo biloba, Ginkgoaceae tree plant, short branches black-gray; winter buds yellow-brown, often ovoid; leaves fan-shaped, long-petiolate, light green, glabrous; leaves on young trees and budding branches are often larger and y lobed, leaves are spirally dispersed on one-year-growing branches, turning yellow in the fall before deciduous; bulbous flowers are dioecious and unisexual; anthers are long ellipsoidal; seeds are long-stalked, often ellipsoid; flowering in March-April; seeds ripen in September-October. Chinese medicine white fruit is peeled off the fleshy outer seed coat of the seed kernel, shell white, so named white fruit.
The white fruit is native to China, is China's endemic plants, now in China as far north as Liaoning, south to Guangdong, east of the coastal provinces, west to southern Gansu and the eastern edge of the Hengduan Mountains distribution, in Japan, North Korea, Europe, the Americas are also cultivated. Baiguo is a light-loving tree species, deep-rooted, wide adaptability to climate and soil, but does not tolerate saline and alkaline soil and too wet soil. White fruit commonly used live seedlings, transplanted seedlings or root seedlings for grafting propagation.
Planting techniques of white fruit
White fruit is commonly used in live seedlings, transplanted seedlings or root tillers for grafting propagation, as well as seed, planting, should not be planted on shady slopes, waterlogged or saline soil is too heavy.
Seeds harvested in the fall, the year of sowing or the following spring sowing, spring sowing needs to be mixed with sand germination, the amount of seed sown per 1hm600-675kg, lateral ditching, ditch spacing of 25-30cm, 4cm deep, every 10cm sowing of 1 seed, mulch 3-4cm, the year of the seedling height of 25-30cm, after the fall of the leaves in the fall can be transplanted.
Split-plant reproduction: from the strong age of the female mother tree root tiller seedlings to select and retain 4-5 strong seedlings, about 1m high when transplanted. Graft reproduction: in the 30-year-old, vigorous and productive female plants on the selection of 2-3 year-old branches as scion, rootstock with seed propagation of live seedlings, using cut or subcutaneous branch grafting method.
Planting, generally early spring planting, row spacing 5-6cm or 7-8m, before planting according to the size of the sapling hole, hole depth of 40-50cm, width 60-70cm, after the seedling, such as the main root is too long, can be slightly pruned. Cave planting, fill the soil, watering and solid, and then cultivate the soil into a mound. According to the total number of 5% configuration of male trees, male trees according to the wind direction scattered planting, in order to facilitate pollination.
