How is ginkgo sown and can ginkgo be planted with seeds?

Ginkgo biloba has a long lifespan, high trunk, deep roots, large crown, light and shade tolerance, and the plant row spacing should be appropriately enlarged during planning, not too dense and crowded.

2. Planting Ginkgo biloba likes loose, breathable and fertile soil, likes water and is afraid of waterlogging, and likes fertilizer and is afraid of raw fertilizer and thick fertilizer. Therefore, the site conditions should be of good soil quality, otherwise the soil should be replaced. The tree hole should be shallow, the soil ball should not be buried too deep, and the watering pit and drainage ditch should be reserved at the edge of the hole.

It is planted with fertile plain soil first, and then applied a small amount of thin fertilizer every year after it survives.

3. Management Ginkgo biloba should be watered frequently after planting, and it should be "thorough" rather than "accumulating", and pay attention to the trunk and foliar spraying. For plants with thin leaves, yellowish leaf color, and weak leaf development, one should check the roots and rescue, and the other should spray foliar fertilizer and foliar water as appropriate to promote growth.

Fourth, treat rotten plants.

Ginkgo biloba should be checked before planting, if the root is rotten and the root skin is loose, small ginkgo trees should be planted around the dead tree in time, and "bridged" at any time to supplement or replace the dead roots, and promote the recovery of the original stem and original branches.

Ginkgo biloba seeds can be planted.

Ginkgo biloba seed planting time.

Many people are asking about the planting method and time of ginkgo seeds, first of all, we must know that ginkgo seeds can be planted in March and April in spring and October and November in autumn every year, but it is best to choose to plant ginkgo seeds in March in spring, because the weather and climate during this time period are consistent with the growth environment required by ginkgo, which is suitable for seed germination and growth.

Ginkgo biloba seed planting method.

1. Seed selection.

When planting seeds, it is necessary to choose the fruits of ginkgo trees that have grown for about 80 years, and select excellent fruits with large particles that are not damaged on the appearance and full as seeds, so as to avoid the growth of seeds with dark damage and signs of growth weakness, resulting in low survival rate.

2. Seed treatment.

When planting, it should be treated in seasons, and the outer skin of the seeds should be removed when planting in autumn and autumn, and then the seeds with the peel should be dried and plantedWhen planting in spring, the seeds should be soaked in warm water at a temperature between 20 and 23 for about 2 3 days, and then put them in the sand for germination treatment, waiting for the next operation.

3. Planting soil.

The seed planting soil should be planted in a sandy slightly acidic soil with air permeability, good drainage and rich nutrients as the base bed, and the soil mixed with river sand, humus soil and lime soil in a suitable ratio of 4:3:3 can be used to promote the germination and healthy growth of seeds.

4. Seeding management.

When sowing ginkgo seeds, it is necessary to dig a pit every 3 4cm in the soil, throw 1 2 seeds into each pit, and then use soil to fill and compact, and germinate after about 20 days; When the seedlings grow, we should carry out 2 or 3 weeding operations, once in the germination period, once in the growth period and once in the setting period, so as to avoid the excessive growth of weeds and the consumption of unnecessary nutrients to affect the growth of the plant. After sowing, Bikagen can be used to improve the survival rate.

Ginkgo biloba is mainly propagated from seeds, and it is a solid seedling with a long lifespan. Now because of the high seeds, there are many people who are propagated by cuttings.

Ginkgo biloba sowing seedlings, as long as the seeds are selected, the nursery is selected, the base fertilizer is applied, and the management and protection are appropriate, it can generally be successful. By using methods such as germination first, then sowing, or even raising sprouts first, and then transplanting and nursery cultivation, it is more certain that strong seedlings can be raised within one year. The annual seedlings with strong growth can reach 1 0 cm in diameter and more than 30 cm in height, and can form seedlings with 20-30 leaves and strong roots.

This kind of seedling can be used as a rootstock grafting excellent variety in the autumn of that year.

Ginkgo biloba is usually sown in spring, but it is mostly carried out in early April. The climate at this time is warm and the temperature is gradually rising, which is helpful for the seeds to take root and germinate. Seedlings are very afraid of light and strong light, so if they are sown in summer, the survival rate is not high, and it will also affect their development, and it is difficult to recover in autumn.

It can also be sown in autumn and winter, but it usually doesn't germinate until spring.

In order for ginkgo biloba seeds to have a higher germination rate, it needs to be germinated in advance. Prepare a pot of warm water, soak the seeds in it, soak for 2-3 days, and change the water every day. After that, take it out and put it on plastic paper, spray it with a watering can in the morning or evening, keep it moist, and it will sprout in about a week.

Ginkgo biloba should generally be planted in a relatively high place, and at the same time ensure that the water source is sufficient and the drainage is good. Before planting, the ground should be leveled, and the fertilizer should be turned into the ground and the seeds should be sown into the soil, and the bud tips should be pointed downwards if they sprout. For large-scale sowing, the row spacing should be controlled between 20-30 cm, and the plant spacing should be 10 cm, so as not to affect growth.

Ginkgo biloba fruits fall naturally when ripe, and if they are exposed to strong winds, they will roll down to other places, and as long as there is a suitable environment, the seeds will take root and sprout.

1. Substrate: The choice of soil is more important for planting, choose a substrate with deep soil layer and good drainage ability, sandy loam is the best, but it also needs to contain nutrients, and the pH value needs to be smaller.

2. Seeds: It is best to choose a mother tree that has been planted for about 80 years, and the quality should be excellent and bear many fruits. The seeds should be harvested with large grains, so that the growth will be relatively good in the future, and there will be little weakness in the growth situation.

3. Treatment: If the seeds are sown in autumn, remove the outer seed coat, and then dry the seeds with the peel. If you choose to sow it in the spring, you must soak it in water and mix it with moist sand to promote germination.

4. Put the treated germ horizontally in the ditch, cover it with 3 4 cm thick soil and compact, and the seedlings can grow to 15 25 cm tall in that year.

Spring and autumn are good times, and autumn planting is carried out in October and November, so that the root system can have a long recovery time. In this regard, spring is not as good as autumn.
