1、 Breeding environment

1. Soil: rubber trees like loose and fertile sandy soil, which can be mixed with rotten leaf soil, garden soil and sandy soil

2. Watering: in spring and autumn, the soil should be kept moist. In summer, there is a great demand for water. Watering should be carried out every day, and the amount of watering should be increased appropriately. Water should be often sprayed on the leaves or around to improve the humidity in the air. In winter, the soil should be kept slightly dry

3. Fertilization: apply fertilizer appropriately, but use less nitrogen fertilizer. If there is too much nitrogen fertilizer, the stems and leaves will grow in vain. Apply rotten liquid fertilizer at an interval of 20 days during the growth period. In order to control the height of formed plants, mixed liquid fertilizer should be applied every 2 months during the growth period

4. If you want the rubber to grow in a proper place, you need to give it enough sunlight. If you want the rubber to grow in a proper place, you should pay attention to it

2、 Breeding method

Cutting propagation: generally cutting in spring and autumn. If watering is unreasonable in summer, the cuttings are easy to rot. Leave the middle section of the branch and leave a leaf. When cutting, seal the upper and lower cuts of the branch to prevent the outflow of juice from affecting the survival rate. Insert it into the soil and maintain the growth temperature of 20 ℃, and it will take root in about a month

3、 Common diseases

1. Gray spot disease: rainy season is the vigorous period of the disease. Gray spots will appear after illness, which will not only expand, but also the leaves will become dry and cracked and appear black particles. Carbendazim can be sprayed during the disease

2. Anthrax: it will harm the leaves, resulting in brown or white spots on the leaves. In serious cases, the whole leaves will become dry and black. The diseased leaves should be removed in time, and ventilation and light transmission should be strengthened at ordinary times
