Ginkgo cultivation techniques
Breeding with seeds, ramets, and grafts. After the seeds are harvested in autumn, they are planted in the same year or in the spring of the next year. The spring sowing needs mixed sand and germination. The seeding rate is 600-675kg per 1hm, the horizontal ditching, the groove distance is 25-30cm, the depth is 4cm, and one seed is planted every 10cm. 3-4cm, the seedling height is 25-30cm, and it can be transplanted after falling leaves in autumn. Phytoplankton Breeding 4-5 strains of strong seedlings were selected from the roots of young female roots, and transplanted when the height was about 1 m. Grafting and breeding In the 30-year-old, the 2-3-year-old shoots of the growing and prosperous female plants are scions, and the rootstocks are seeded with seedlings, grafted by splicing or subcutaneous grafting. Colonization, generally early spring planting, plant spacing 5-6cm or 7-8m, before planting according to the size of the seedlings open hole, hole depth 40-50cm, width 60-70cm, after the seedlings, if the main root is too long, can be slightly trimmed. Cave planting, filling soil and watering and then cultivating the soil into a mound. The male trees are arranged at a total of 5%, and the maple trees are planted in a wind direction to facilitate pollination.
The cultural background of ginkgo
The world's first apricot male tree (Ginkgo biloba) Xincun ancient ginkgo tree, grown in the former site of Guanzhu Temple, the ginkgo ancient plum garden on the north side of the current Xincun Township government residence, was planted in the Tang Dynasty or before, and the current tree height is 38 meters. The breast diameter is 226 cm, and the shade covers an area of about 0.9 mu. It is the oldest ginkgo tree in existence. Ginkgo trees have higher growth potential, and most of the surface roots are exposed to the soil layer, but this tree has early germination, late leaves, and strong growth. Known by the locals as the Ginkgo King.
Review
Ginkgo biloba is a deciduous tree that blooms in May and matures in October. The fruit is orange-yellow. Ginkgo is a relict plant. All other plants with its door are extinct. Ginkgo biloba is the oldest relict plant in the existing seed plants. Varieties and varieties are yellow leaf ginkgo, tower-shaped ginkgo, cracked ginkgo, weeping ginkgo, zebra gingko. Ginkgo biloba grows slowly and has a very long life. It takes more than 20 years from planting to the result. After 40 years, it can produce a large number of results. The life expectancy is over a thousand years old.
Ginkgo first appeared in the Carboniferous years 345 million years ago. It has been widely distributed in the northern hemisphere of Europe, Asia, and the Americas. The Mesozoic Jurassic Ginkgo biloba was widely distributed in the northern hemisphere and began to decline in the Late Cretaceous. 500,000 years ago, the Quaternary glacial movement occurred, and the earth suddenly became cold. Most of the ginkgo plants were extinct and extinct in most parts of Europe, North America, and Asia. Only when China’s natural conditions are superior, it is miraculous. Save it. Therefore, it is called "living fossil" by scientists, "panda in the plant world." The wild state of Ginkgo remains in the mountainous area of western Zhejiang Province in the northern part of Shandong Province (Cangzhou City) in the south of Shandong Province. Zhejiang Tianmu Mountain, Anlu City, Hubei Province, Dabieshan, Shennongjia, and other places have wild and semi-wild ginkgo communities. Because the individual is sparse, dioecious, if not strictly protected and promotes natural regeneration, the remaining forest will be replaced. Most of the ginkgo distribution belongs to artificial cultivation areas, mainly cultivated in China, France, and South Carolina. There is no doubt that foreign ginkgo is imported directly or indirectly from China.
Ginkgo, health and prolonged, Ginkgo was listed as a royal tribute in the Song Dynasty. Japanese people have the habit of eating ginkgo daily. Westerners must have ginkgo for Christmas.
In terms of eating methods, ginkgo mainly includes fried food, baked food, cooking, side dishes, pastries, preserves, canned food, and beverages.
However, the amount of ginkgo used and the improper eating method can cause poisoning. (mainly refers to the situation of excessive food intake) In order to prevent ginkgo poisoning, cooked food and small food are the fundamental methods. The raw food (shelling, membrane heart) is 5~7 in adults, and the children are 2~5 capsules according to the age and weight and can be taken after 4 hours. Raw food must be shelled to the red soft membrane, to the heart (germ).
