Culture methods and matters needing attention of Pinus elliottii

The method of cultivating Pinus elliottii: prepare and breed with garden soil, rotten leaf soil, peat soil, perlite or coarse sand, move into indoor maintenance when overwintering, shade properly in summer, give sufficient light in other seasons, keep basin soil moist during culture period, apply nitrogen-based fertilizer once a month, but stop fertilization in winter. Matters needing attention for breeding Pinus elliottii: prune the overgrown branches and buds in time and change the basin every 2-3 years.

I. the method of raising money pine

1. Soil

The main results are as follows: (1) Pinus elliottii likes the slightly acidic sandy soil with loose fertility and good drainage, and can grow normally in neutral soil, but avoid alkaline soil.

(2) Pinus elliottii is a mycorrhizal tree species, so there must be mycorrhiza in the soil to ensure the normal growth of Pinus elliottii.

(3) the nursery bed for general sowing and cutting propagation needs to be mixed with human mycorrhizal soil, and when transplanting into the basin, it is also necessary to bring more resident soil to ensure mycorrhiza, so the substrate can be prepared and cultured with garden soil, rotten leaf soil, peat soil, perlite or coarse sand.

2. Temperature

Pinus elliottii likes to grow in a warm environment and is relatively cold-resistant. It can generally endure a low temperature of-20 ℃, but it is best to move it indoors for maintenance when it is overwintering.

3. Lighting

(1) Pinus elliottii likes plenty of sunlight, but the seedlings are not resistant to direct sunlight, so they need proper shading, otherwise they will cause burns.

(2) when it is hot, sunny and poorly ventilated in summer, the leaf tip is often scorched, so it is necessary to cover the sun around noon and take good ventilation measures, otherwise it will affect the growth and development of the plant. Sufficient sunshine can be given in other seasons.

4. Watering

(1) money pine is not resistant to drought, so when the basin soil is relatively dry, it needs to be watered in time to keep the basin soil moist, especially when planting in a shallow basin, it is more necessary to avoid drought in the basin soil, otherwise it is easy to produce scorched leaves.

(2) avoid wet water, too wet basin soil will affect plant growth, defoliation and even root rot, it is necessary to pour the stagnant water in the basin in time after rain, and stop watering after dormancy in winter.

5. Environmental humidity

Pinus elliottii likes to grow in a humid environment. In the process of growth, it is necessary to spray water to the branches and leaves and the surrounding environment, which is helpful to improve the humidity in the air.

6. Fertilization

Money pine can not tolerate hemorrhoids. In the process of growth, nitrogen-based fertilizer should be applied once a month to promote the growth of branches and leaves. Alkaline fertilizer should not be applied during this period. Ferrous sulfate can be added when fertilizing. During the rainy season, high temperature in summer and winter dormancy, fertilizer should be stopped.

II. Matters needing attention in breeding Pinus elliottii

1. Pruning

The main results are as follows: (1) the sprouting power of Pinus elliottii is relatively strong, and the unnecessary branches and buds need to be cut off in time in spring. The shaped plant can keep 1-2 nodes short when the new branches and leaves are extended and the long branches are long, which is beneficial to keep the branches flat.

(2) in general, when shaping with wire, attention should be paid to the timely removal of the wound wire when the wire is embedded in the human bark, so as not to affect the normal growth of the tree.

2. Turn the basin

In the process of culture, the pots should be changed every 2-3 years, generally after falling leaves in autumn to before sprouting in spring, and pay attention to prevent diseases and insect pests such as crushing disease, stem rot and big coir moth.
