How to plant ginkgo seeds? Introduction to sowing methods of Ginkgo biloba seeds

Ginkgo biloba is the oldest relict plant among gymnosperms left over from the Quaternary glacier movement. Seed reproduction is mostly used for large-scale greening seedlings or for making cluster-type bonsai. The outer seed coat is usually removed after the seeds are harvested in autumn, and the seeds with pericarp are dried. It can be sowed in winter that year or in the next spring. Let's take a look at how ginkgo biloba seeds are planted.

Budding time

The time of accelerating germination depends on the time of sowing, and the time of sowing takes the late frost period as the standard, because the young buds of Ginkgo biloba are vulnerable to freezing injury when the bud is less than 0 ℃, it can be started 30-40 days before the sowing time. It is better to sow seeds in the capital at the beginning of March.

Nursery bed making

Select a piece of land with a leeward direction and a flat ground, and dig a trench with a depth of 30cm and a width of 120cm. The length of the ditch depends on the number of seeds, the lower layer is about 5cm of fine sand, and a 10cm ridge is added around the ditch (which can be appropriately higher in the north). To prevent Rain Water from inflow.

Seed treatment

Take out the seeds stored dry in winter, first put them into a jar or other container containing water, soak them in clean water for 36 hours, and separate the shrunken grains, then remove and wash them, then mix them well with 1 part of seed and 3 parts of wet sand, that is, go to bed to promote germination, and the seeds stored in the cellar can be put directly into the seedling bed to accelerate germination.

Seed to bed

Spread the seeds mixed with sand evenly on the seedbed, then put 5 centimeters of fine sand on top of the seeds, and then put a thin layer of soil or grass on top to maintain the temperature in the seedbed, and finally cover the seedbed with a plastic film with a width of 2 meters. the film can be compacted with soil around it.

Transplanting and planting

The seedlings propagated by Ginkgo biloba seeds can grow up to 15-25 cm high in that year and can be transplanted after defoliation in autumn, but it should be noted that the seedling bed should choose areas with good drainage to prevent stagnant water from rotting the part of the seedlings near the ground. It can grow well in acid soil and calcareous soil, while neutral or slightly acid soil is the most suitable, where it is not resistant to stagnant water, it is more resistant to drought, and it grows poorly only in too dry places and stony slopes or low wet places.

How to plant ginkgo seeds? Sowing and Propagation methods of Ginkgo biloba

Ginkgo tree, also known as ginkgo, Gongsun tree, duck foot tree, etc., is a deciduous tree of the Ginkgo biloba family. Ginkgo biloba has both edible, medicinal, garden ecological and economic value, and has a high planting value. The method of sowing and reproduction is often used in the planting process of ginkgo trees, so how to plant ginkgo seeds? The sowing and propagation methods of ginkgo biloba are introduced as follows.

First, budding time

The time of accelerating germination depends on the time of sowing, and the time of sowing takes the late frost period as the standard, because the young buds of Ginkgo biloba are vulnerable to freezing injury when the bud is less than 0 ℃, it can be started 30-40 days before the sowing time. It is better to sow seeds in the capital at the beginning of March.

Second, the manufacture of seedbed.

Select a piece of land with a leeward direction and a flat ground, and dig a trench with a depth of 30cm and a width of 120cm. The length of the ditch depends on the number of seeds, the lower layer is about 5cm of fine sand, and a 10cm ridge is added around the ditch (which can be appropriately higher in the north). To prevent Rain Water from inflow.

3. Seed treatment

Take out the seeds stored dry in winter, first put them into a jar or other container containing water, soak them in clean water for 36 hours, and separate the shrunken grains, then remove and wash them, then mix them well with 1 part of seed and 3 parts of wet sand, that is, go to bed to promote germination, and the seeds stored in the cellar can be put directly into the seedling bed to accelerate germination.

Fourth, seeds go to bed

Spread the seeds mixed with sand evenly on the seedbed, then put 5 centimeters of fine sand on top of the seeds, and then put a thin layer of soil or grass on top to maintain the temperature in the seedbed, and finally cover the seedbed with a plastic film with a width of 2 meters. the film can be compacted with soil around it.

5. Transplanting and planting

The seedlings propagated by Ginkgo biloba seeds can grow up to 15-25 cm high in that year and can be transplanted after defoliation in autumn, but it should be noted that the seedling bed should choose areas with good drainage to prevent stagnant water from rotting the part of the seedlings near the ground. It can grow well in acid soil and calcareous soil, while neutral or slightly acid soil is the most suitable, where it is not resistant to stagnant water, it is more resistant to drought, and it grows poorly only in too dry places and stony slopes or low wet places.

[conclusion] to do a good job in seed reproduction of ginkgo biloba is the basis of ginkgo planting. The above introduces the sowing and propagation methods of ginkgo trees. I hope it will be helpful to you!

How to plant ginkgo trees with seeds 1. The seeds of sowing and raising seedlings should be harvested with large grains, and the mother trees whose age is about 80 years are the best, and the seeds are peeled and dry. Autumn sowing is available in the south and spring sowing is suitable in the north. The sandy loam with good water permeability should be selected in the seedling bed.

two。 The sprouting shoots with roots on the base half of the seedlings were dug up around February (after thawing in the north) and planted in the nursery with a diameter of 1 cm to 4 cm. This method is easy to survive. It will blossom and bear fruit in about 10 years.

3. Cuttage seedlings in May to June to select the same year's soft branches, cut into 10 cm to 15 cm, leaving 3 to 4 leaves, inserted into half of the taxi often spray water to ensure that the leaves are not dry, about a month and a half to two months can take root.

4. Seedlings transplanting ginkgo biloba with a diameter of less than 5 cm can be planted with bare roots, and more than 6 cm will generally be cultivated with soil. The seedlings planted with bare roots were in the slow seedling stage in that year. The seedlings with dirt can grow in that year. The seedlings were planted in rows and then irrigated with water. As for the planting of big trees, it is best to fill the pit with water before planting, and after the water in the pit has seeped, the big tree will be implanted into the pit to tamp, so that the water in the pit will come back to nourish the roots. The next time it is watered, the diversion ditch should be dug at the edge of the pit and filled with water, so that the water can slowly infiltrate into the root of ginkgo biloba. Do not flood, many people transplant ginkgo not live the main reason is not dry to death, but soak to death. Because the root system of Ginkgo biloba has a large amount of respiration and flood irrigation, so that the root system can not produce new roots due to lack of oxygen and asphyxiation, and the root system gradually rots. Even if some ginkgo biloba is dead, its leaves can still spread out, and even sprout in the second or third year, but the leaves are very small, and when the nutrients in its body are exhausted, it will not sprout. This is the "fake living" phenomenon of Ginkgo biloba. On the other hand, some ginkgo biloba do not send leaves in the first year, or even in the second year. If you pinch the skin, you will find that the skin is fresh and the branches do not shrink. This kind of tree is not necessarily dead. Maybe it can send out leaves in the third year. This phenomenon is also known as the "fake death" phenomenon of ginkgo. To determine whether ginkgo biloba is dead or alive, you can't just look at the leaves, the important thing is to look at the roots. Therefore, the purchase of large seedlings, especially the fake seedlings purchased from outside, must see if the roots are black. if so, it means that the seedlings are fake live seedlings, no matter how cheap they are. The fresh seedling should be the xylem of the root is white, the root bark is slightly red and the xylem is close.
