How long and high is the growth rate of ginkgo seedlings in a year?

The growth rate of ginkgo seedlings is much higher in a year. Ginkgo biloba is a deciduous fruit tree with slow growth, late fruiting and long life. Dioecious, often forming a tall crown, with strong dryness and obvious stratification. The crown of seedlings is mostly tower-shaped, cone-shaped or oval. When the grafted tree lacks the central trunk or the growth of the central trunk is blocked, the crown can be opened into a semicircle or a happy shape in the later growth stage. Branches in the crown are obviously divided into long branches and short branches. Long branches are formed by several buds at the top of branches extending upward and outward, which is the basis of crown. Short-shortened branches are formed by the buds in the middle and lower parts of branches forming clumps first, and then weakly extending and overlapping each year, with extremely short internodes, also known as "scale branches" or "milk branches". Under certain conditions, short branches can also draw long branches. 10 young trees have a high proportion of long branches, which can account for about 70% of the total branches. Trees over 50 years old. The number of long branches has decreased sharply, and the proportion of short branches has increased significantly, accounting for more than 80% of the total number of branches, so the crown of adult trees is often sparse. Sometimes, the hidden buds of old trees or big branches can germinate directly to form short shortened branches.

After reaching fruiting age, the female flowers and male inflorescences of ginkgo trees are clustered on the short branches of female and male plants respectively. There are 5 ~ 14 leaves on the short branch. Generally, thick and short branches with more than 6 leaves can form flower buds. Flower buds are mixed buds, which grow in the neck and bloom in the axils of leaves after extracting extremely short shoots in spring. Each shortened branch on a female plant can bear 2 ~ 14 seeds (usually 5 ~ 6 seeds). Whether flower buds can be formed on short braided branches is related to the nutritional status of trees, the age and growth of short braided branches. Generally speaking, on the 3 ~ 12-year-old base branches, the fruit-setting ability of the shortened branches is the most, and then the fruit-setting ability gradually decreases. The germination rate of long branches of Ginkgo biloba is extremely high. Except the terminal bud, axillary buds on other nodes can produce short branches, forming flower buds and bearing fruit, which is very easy to form big and small years. But sometimes short branches on the same base branch will bear fruit alternately. Male inflorescences are inserted between leaf axils of short-branched male plants, and 4 ~ 6 male inflorescences can be inserted on each short branch.

The flowering and fruiting period of short branches is longer, which can last for 7 ~ 10 years. The basal branches around the crown can be robust for more than 10 years, but the short cut branches on the basal branches or the short cut branches at the base of the basal branches are easy to die after bearing fruit because of poor growth conditions.

Ginkgo entered the fruiting period late, but its economic life is quite long. It often takes 15 ~ 20 years for the seedling tree to begin to bear fruit, and it will enter the full fruit period after 30 ~ 35 years, and the full fruit period can be extended to more than 100 years. Grafted trees and ramets can blossom and bear fruit in 7 ~ 10 years, earlier than seedlings.

The planting environment of ginkgo seedlings is very important in the growth process of ginkgo trees throughout their lives. Improper planting will directly affect its future growth rate and survival rate. Pay attention to the following links before planting: 1. Land selection: The growth of Ginkgo biloba does not require high soil environment, but it is not suitable to plant in plots with deep and fertile soil, good irrigation and drainage conditions, sufficient sunshine and high and dry terrain. 2. Deep pit (ploughing): After the plot is selected, the plot for planting small-sized seedlings should be fully applied with base fertilizer and deeply ploughed for later use; According to the size of seedlings, determine the amount of seedlings per mu, and choose border planting or ridge planting according to the different climate characteristics and rainfall in the north and south to facilitate irrigation or drainage; Large-scale green seedlings should be planted in holes, and the size of holes should be determined according to the thickness of seedlings and the size of soil balls, and the holes should be large but not small. 3. Shallow planting: This is the most easily overlooked important link. Ginkgo trees are the most taboo for deep planting. The depth of seedling planting directly affects the future growth. Ginkgo trees are sensitive to soil permeability and fertility. Therefore, its roots are mostly distributed horizontally on the surface of the stratum, and it is convenient to absorb nutrients and moisture even when breathing. New roots develop rapidly and seedlings grow vigorously. After deep planting, the seedlings are thinner because of poor permeability. The best depth of planting is to keep the original soil trace depth of seedlings, which should be shallow but not deep. In order to prevent seedlings from being blown down by the wind, we can cultivate seedlings with mounds. After the seedlings survive, the mound can be gradually leveled by weeding, watering and fertilizing. Green seedlings need to be fixed with brackets to prevent strong winds from blowing, damaging roots and affecting survival. Fourth, fertilizer and water management: after planting seedlings in early spring, they should be watered immediately because of shallow planting. In case of spring drought, they should be watered regularly, otherwise the survival rate of seedlings will be affected; It is rainy in summer, so we should pay attention to timely drainage to prevent seedlings from being soaked in rain, resulting in rotten roots and dead seedlings. The root system of Ginkgo biloba seedlings planted in that year has not been restored, so it is generally not necessary to apply fertilizer except the base fertilizer applied before planting, and it will be applied after the seedlings return to normal growth in the next year; The fertilizer requirement can be determined according to the growth of seedlings, and the maximum fertilizer application per mu can reach 150kg/ year, and the seedlings will not burn and grow vigorously.
