How do the latest seeds grow?

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.
