Temperature: the temperature for maintaining black pine should be controlled over 15 degrees, otherwise it will be frostbitten; watering: once a week in the growing period, and once every other day in the non growing period; fertilization: in addition to base fertilizer, only two times of topdressing is needed in the whole growing period to meet its needs; lighting: more than four hours of lighting should be guaranteed every day. When it's too strong, it needs to be shaded.

I. maintenance method

1. Temperature: it is not cold resistant and suitable for growing in warm and humid marine climate. The curing temperature should be controlled between 15 ℃ and 30 ℃.

2. Watering: first of all, in the selection of soil, the soil with good drainage should be used, because it is not resistant to water logging. If the soil with good drainage is used, even if it is watered too much, there will be remedies. Generally, water twice or three times a week. During the growing period, proper water control is needed, which can make its branches grow thick and short, its needles are short and small, which can increase the ornamental value. In summer, the temperature is relatively high. Besides watering the roots, spray water mist to the branches to cool them.

3. Fertilization: it is more resistant to barren soil. Before planting, it is necessary to mix base fertilizer in the soil, which is good for the growth of seedlings. After the plants are grown, it is necessary to apply fertilizer twice in the growth period, and no fertilization is needed in other time. Reasonable fertilization can increase the ability of plants to resist diseases and insect pests.

4. Light: it likes the sun and needs to be cultured in an area with sufficient light. If it is planted in the open, it needs to be raised in a sunny place. If it is sprayed on the plant, it needs to be raised in a sunny place, such as a balcony, so as to meet its demand for light. The light hours every day are at least four hours.

After the dried seeds are rubbed off and threshed, they are stored in sand. Secondly, it needs reasonable land preparation, and its seedlings need to grow in the soil with good drainage and soft soil. After the soil is ready, put the seeds in potassium permanganate solution for two hours, then soak them in warm water for two hours. After the above steps are completed, the seeds can be sown in the soil, and the seedlings can emerge in a week.

2. Pruning: it needs to be pruned once a year in winter, so that its shape can be adjusted, and some long and bad branches can be cut off; it needs to be sprouted once a year in spring, so as to promote the growth of lateral branches.

3. Problem diagnosis

1. Disease: if the plant has yellow branches and leaves, it may be infected with bacterial wilt. It is necessary to remove and destroy the diseased leaves in time, and then spray it with thiophanate methyl diluent..

2. Insect damage: during the growth period, the plant is easy to infect the pine aphid. They will absorb the sap of the plant and affect the growth of the plant. After discovering insect pest, need to kill insect as soon as possible, can use bodol liquid to carry on treatment..

4. Other issues

1. Edible: it is inedible.

2. Whether it can be cultured indoors: it can be cultured indoors.
