Ginkgo (scientific name: Ginkgo biloba?L.) is the Ginkgoaceae, Ginkgo biloba plants, also known as white fruit, Gongsun tree, duck's foot, duck paw tree

Ginkgo planting technology:

Planting site selection

Because of the ginkgo tree's slow growth cycle, its need for nutrients and light conditions are more than adequate, so the conditions of the site as much as possible. Choose a location with high terrain, convenient transportation, and good drainage. Planting ginkgo seedling garden should also pay attention to the selection of thick soil layer garden, generally require a soil layer thickness of more than 1 m. In addition, it is also necessary to ensure sufficient light and good air circulation, that is, try to avoid choosing the valley and other weak ventilation, weak light planting ginkgo place. Ginkgo planting, for plant spacing, planting direction of the configuration should pay attention to, preferably east-west planting, and maintain a certain planting density, you can choose 2 meters × 2 meters of planting density. Because of the ginkgo light, east-west planting can ensure that the ginkgo by the north-south direction of the light is more adequate, and sparse density can also ensure that its growth process is not affected by other neighboring trees.

Planting time selection

Ginkgo tree planting time is affected by temperature, location and other factors, according to the different regions and determine the different planting time. For areas south of the Yangtze River, ginkgo planting time can be selected in the late fall and early winter stage, the southern winter land still has a certain ground temperature, basically able to ensure that ginkgo planted after the damage to the root system recovery needs, while promoting the rapid growth of ginkgo the following year. For areas north of the Yangtze River, ginkgo planting should be delayed until after the spring equinox.

Planting hole treatment

For ginkgo planting hole treatment should also be based on the planting groundwater level and soil properties for comprehensive judgment, sandy soil or sandy loam plots, planting holes should be slightly smaller, so that can effectively retain water. At the same time, the configuration of the planting hole should also be based on the root system of the ginkgo transplantation to decide, the general dense root should be planted in a large pit.

Sapling selection

Ginkgo tree planting another key factor in the survival of the selection of saplings, generally choose the more developed root system, and the trunk is more straight ginkgo seedlings. In the selection of seedlings, but also pay attention to avoid choosing seedlings with pests and diseases, choose seedlings planted without the influence of pests and diseases. Before planting, the root system of ginkgo bare-root seedlings is quickly soaked in lime water, and then cleaned with water.

Other precautions

In the process of planting, the topsoil is backfilled first, and then the heart soil is piled up around the plant to form a small mound. After filling the soil, the ginkgo sapling should be gently pulled upwards to ensure that the ginkgo root system is smooth, after which the soil around the plant should be stepped on and the Trumgenbidol rooting agent should be applied.

Fertilization

Ginkgo has a high demand for fertilizer and is a fertilizer-loving and fertilizer-tolerant plant, so scientific fertilization is an important part of its management. Generally speaking, spring March-April is the ginkgo's long leaf period, it is appropriate to apply the fertilizer to promote the growth of leaves. Generally in February before and after the fertilization, to fast-acting fertilizer mixed with organic fertilizer-based, plant average Cuimu granular compound fertilizer 2-5 kg, mixed organic fertilizer, such as well-rotted human urine 5-10 kg, generally according to the size of the tree to control the amount of dosage. Summer for ginkgo long fruit period, it is appropriate to apply fertilizer to promote long fruit, generally in early July each year for fertilization, ginkgo plants are applied 0.5 kg of urea. Fertilizer in the event of persistent drought, should be appropriate watering watering. Autumn is the ginkgo leafing period, it is appropriate to apply nutritious tree fertilizer, such as Trimm foliar fertilizer. September-October is the ginkgo seed maturity, harvest time, after which the ginkgo began to leaf.

Cold protection and warmth

Winter is usually wrapped around the trunk of the ginkgo tree with grass ropes to protect it from the cold. In addition, you can also choose to white the trunk for warmth, white generally choose to add salt sulfur compound, white in the fall, white the trunk can reduce its absorption of solar radiation, reduce the impact of the temperature difference between day and night, white the ginkgo tree is generally not frozen.
