Cultivation methods and precautions of black pine

1. Maintenance methods

1. Temperature: It is not cold-resistant and is suitable for growing in warm and humid marine climate areas. The maintenance temperature should be controlled between 15 degrees and 30 degrees.

2. Watering: First of all, when choosing soil, you should use soil with good drainage. Because the plant is not resistant to waterlogging, using soil with good drainage will provide a remedy even if you water too much. Generally, water it two to three times a week. During the growing period, proper water control is needed to make its branches grow short and thick and the needles short, which can increase its ornamental value. The temperature in summer is relatively high, so in addition to watering the roots, you should also spray the branches with water mist to cool them down.

3. Fertilization: It is relatively resistant to barrenness. Before planting, you need to mix base fertilizer into the soil, which is good for the growth of seedlings. After it becomes a mature plant, you need to apply fertilizer twice during the growth period. No fertilizer is needed at other times. Reasonable fertilization can increase the plant's ability to resist diseases and pests.

4. Light: It likes sunshine and needs to be grown in an area with sufficient light. If it is planted in the open field, it should be grown in a sunny place. If it is sprayed on the plant, it needs to be grown in a sunny place such as a balcony to meet its light needs. The daily light time is at least four hours.

2. Breeding techniques

1. Reproduction: It can be propagated by sowing. First, you need to pick the mature seeds, then put them in a cool and ventilated place to dry, rub off the peel of the dried seeds, thresh them and store them in sand. Secondly, the land needs to be prepared properly. Its seedlings need to grow in soil with good drainage and loose texture. After the breeding soil is prepared, soak the seeds in potassium permanganate solution for two hours, and then soak them in warm water for two hours. After completing the above steps, you can sow the seeds into the soil and they will sprout in a week.

2. Pruning: It needs to be heavily pruned in winter every year to adjust its shape and cut off some branches that are not growing well; it needs to be pruned once in spring every year to promote the growth of side branches.

3. Problem Diagnosis

1. Disease: If the branches and leaves of the plant turn yellow, it may be infected with dead branch disease. The diseased leaves need to be removed and destroyed in time, and then the plant should be sprayed with diluted methyl thiophanate.

2. Pests: During the growth period, the plants are easily infected by pine aphids, which will absorb the sap of the plants and affect their growth. After discovering the pest, it is necessary to kill the pests as soon as possible. You can use Bodor liquid for treatment.
