Cultivation methods and precautions of black pine.

Temperature: The temperature of the black pine should be controlled above 15 degrees, otherwise it will be frostbitten; Watering: During the growing season, you need to water once a week, and when you are not in the growing season, you need to water once every other day; Fertilization:

In addition to the base fertilizer, the whole growth period only needs to chase the water-soluble fertilizer twice to meet its needs; Light: The light should be more than four hours a day, and shade should be required when the light is too strong.

The leaves of the pine tree are yellowish. If the nutrients are insufficient and the iron is lacking, you can pour ferrous sulfate solution to supplement iron. If it is caused by lack of water, it should be watered, but not too much at one time.

If it is caused by just transplanting and not adapting, you can water the rooting water, pay attention to maintenance and management to promote the adaptation and growth of pine trees. If it is caused by an infected disease, cut off the diseased branches and leaves, and then spray the disease with fungicidal drugs.

Yellowing of pine leaves is simple**.

1. Supplement iron Yellowing Causes: Pine trees need nutrient support in their growth, and they have more demand for iron, and if there is a lack of iron in their growth, it may lead to yellowing of leaves and poor growth.

Solution: In the growth stage of pine trees, attention should be paid to reasonable fertilization to ensure nutrition, if it is determined that the pine tree lacks iron, you can reasonably apply compound fertilizer, watering ferrous sulfate solution to supplement iron.

2. Ensure moisture.

Causes of yellowing: During the growth of pine trees, they should be watered in time to ensure a good water supply. The yellowing of the leaves of pine trees may be due to insufficient watering and lack of water, and the roots cannot absorb water, and in the long run, the leaves will naturally turn yellow.

Solution: In the growing season, it should be watered reasonably according to the growth needs, and after the pine tree is found to be dry and short of water, the pine tree should be watered and irrigated in time, but pay attention to not overwatering at one time.

3. Promote rooting and adaptation.

Causes of yellowing: Freshly transplanted pine trees with untied roots may also cause yellow leaves.

Solution: Water the pine tree with rooting water to promote rooting, pay attention to maintenance and management, and wait for the pine tree to adapt to growth.

Fourth, ** disease.

Causes of yellowing: If the growing environment is not suitable, it may cause pine trees to become infected and cause yellowing of leaves.

Solution: Determine the disease of the pine tree, cut off the diseased branches and leaves in time, and then spray fungicides to cure the disease, and spray it several times in a row.

Method:

Many trees have large leaves and many stomata to evaporate a large amount of water, and the fall of the leaves can reduce the consumption of water in the tree. Pine and cypress trees have much smaller leaf shapes than other leaves, and they do not consume much water on their own. Moreover, the surface of the leaf has a thick waxy layer, which makes it neither afraid of cold nor evaporating much water, so it looks evergreen all year round.

In fact, pine trees and cypress trees do not lose their leaves, but they only change their leaves once every three or five years, and the leaves are not all changed together, but in batches.

Pine: The vast majority are tall trees, 20 to 50 meters tall and up to 75 meters tall (American sugar pine. Very few are shrub-like, such as Pinus glais (and Pinus terrasis ( .

Pine trees are wheel-shaped branches, with long internodes, relatively thin and straight branches or slightly curved downwards, and slender needles in bundles. The canopy of the tree does not look compact, and the word "pine" is a visual description of the characteristics of its canopy. Therefore, "pine" is a type of tree with a canopy pine.

Pine trees are sturdy and have a very long lifespan.
