1. Seed seedlings should be harvested large particles, the mother tree is about 80 years old is best, the harvested seeds are peeled and dried. The south can be sowed in autumn and the north is suitable for spring sowing. The seedbed should use sandy loam with good water permeability. 2. Use sprouting propagation to propagate seedlings. Before and after February (after freezing in the north), dig out the rooted buds on the base and plant them in a nursery. The diameter is from 1 cm to 4 cm. This method is easy to survive. About 10 years can bear fruit. 3. Cutting seedlings Use softwood shoots of the year from May to June, cut into 10 cm to 15 cm, leave 3 leaves to 4 leaves, insert half the water often to ensure the leaves do not dry, about one and a half months to two Months can take root. 4. Seedlings transplanted Ginkgo biloba diameter can be planted in bare roots below 5 cm, and soil culture should generally be carried out above 6 cm. The seedlings planted on bare roots were seedlings of the year. The soil with seedlings can grow that year. After the young seedlings were planted, they were flooded with water. When planting large trees, it is best to fill the pits with water before planting. After the water in the pits has percolated, the trees will be planted in the pits for compaction, allowing the water in the pits to return to moisten the roots. The next watering should dig the ditch around the pit to fill the water, allowing the water to slowly infiltrate the root of the ginkgo. Do not flood irrigation, many people transplanted Ginkgo biloba is not the main reason why it does not die, but bubbled to death. Because the roots of Ginkgo biloba have a large amount of respiration and flood irrigation, the lack of oxygen in the roots suffocates and no new roots are produced, and the roots gradually rot. Even if some ginkgo dies, its leaves can still be unfolded, and even the second and third year can still germinate. However, the leaves are very small. When the nutrients in the body are consumed, it leaves no leaves. This is the “false living†phenomenon of Ginkgo biloba. Some ginkgo biloba leaves do not grow in the first year or even in the second year. If the skin is fresh, the skin is not fresh and the branches do not shrink. This tree is not necessarily dead. The third year will be able to issue leaves. This phenomenon is also known as the phenomenon of “dead death†of Ginkgo biloba. To determine whether ginkgo is suspended or faked, you can't just look at the leaves. It's important to look at the roots. Therefore, buying large seedlings, especially fake seedlings purchased from outside, must see if the roots are black. If it is, it means that the seedlings are fake live seedlings, and they cannot be cheaper. The fresh seedlings should be the roots of the xylem white, the root bark slightly red and the xylem close. 5. Management of Seedlings (1) Ginkgo does not need regular irrigation after being alive. In northern areas, water is poured before germination after defrosting. In May, if the weather is dry, water can be poured once, because this is Ginkgo biloba, the peak of growth in the middle of the year. In the autumn, in mid-August, Ginkgo biloba is the second peak of growth in the year. It can be used to pour water once. Both irrigations can be combined with fertilization. (2) Fertilization: The fertilization in the nursery can be carried out in the spring and summer. In the spring, between 5,000 and 10,000 pounds of organic fertilizer is applied per mu between two rows, and then the soil is ploughed again with a small rotary cultivator to make the fertilizer uniform. Into the soil, large seedlings can open a few of the radial ditch, the organic fertilizer and topsoil and mix it into the ditch, if the amount of spring fertilization, once a year can be, small amount is in the mid-August make-up time. (3) pruning: Ginkgo generally do not have to trim, because the amount of Ginkgo biloba shoots less hair, even if the seedling nursery, it should try to keep more foliage, in order to facilitate its accelerated thickening. The year before the seedlings are to be sold, the branches under 1.8 m will be cut. After one year of growth, the cuts will be covered, the skin will be smooth, and the branches will stand upright. (4) Intertillage: Appropriate cultivator can improve the soil permeability condition. The cultivator has a pruning effect on the fibrous roots of ginkgo biloba, which can stimulate more fibrous roots to germinate. The number of cultivating times can be once in spring and autumn. (5) Disease prevention and pest management: The disease of ginkgo is mainly the blight of seedling stage. The main insect pest in the field is the scarab larvae. During the seedling period, pay attention to ventilation and humidity, loosen the topsoil, and spray Bordeaux mixture to prevent blight. The method of controlling earthworms is to use as much organic fertilizer as possible. When fertilizing, the whole garden will be sprayed with a 3911 pesticide 500 times once, and then the soil will be sprayed and fertilized. Another way is to mix the bran, rice bran, etc., and mix it with trichlorfon. Put it in a bucket for two days. Allow it to fully absorb the pesticide and then spread it into the ground and then cultivator. Another way is to bury a bunch of dry grass every 10 meters or so, and always put some water on the withered grass. Open the hay every two months. (6) The cultivation of the result tree: Ginkgo biloba is dioecious, cross-pollination, so the result tree should be configured pollination tree, Ginkgo biloba pollination ability is very strong, in the breeze wind downwind 25 km are effective pollination area, male and female The difference between the trees is that the female trees have obvious growth, the branches grow flat and the leaves are dark, while the male branches stand vertically. Ginkgo biloba orchard is planted at a spacing of 4m 6m. Seedlings grow at a fast speed. Seedlings with breast diameters from 3cm to 4cm are selected and grafted in a truncated manner. Generally, branches are used, and the scion is selected for 3 years. The skin is shiny and comes with From 3 to 6 short branches, the result is that good varieties with large grains are good. 3 to 4 years after grafting can be fruited.
