1、 Breeding environment

1. Soil: Cactus belongs to desert plant, which is suitable for acidic or weakly acidic soil. It can be mixed with rotten leaf soil, garden soil, coarse sand and rotten bone meal

2. Watering: Cactus likes a humid environment. Spring, summer and autumn are the peak growth season. At this time, it is necessary to increase the amount of watering to ensure that the soil is wet. If it is cultivated indoors, it is necessary to often spray water around to enhance the air humidity. After the soil is dry in winter, it is necessary to water the classroom. If the indoor temperature is low in winter, the soil should be kept slightly dry

3. Light: shade measures shall be taken when strong light is shining in summer. In other seasons, it can be placed in a place with sufficient light. Don't put it in a cool place indoors for a long time, otherwise the color will turn black. About 2-3 days a month should be placed outdoors to receive light

4. Fertilization: generally, phosphorus fertilizer is the main fertilizer, and the amount of fertilization should not be too much, otherwise the soil concentration will be greater than the root concentration, and the cactus will be dehydrated

2、 Breeding method

1. Cutting propagation: cut the ball with a knife. If the wound is too large, dry it. Put it on the sand and don't insert it into the sand; Sand noodles should have less water after planting. After planting, they should be cultured indoors at a temperature above 20 ℃ and can be born in a month

2. Sowing and propagation: after soaking the seeds in warm water for 3 days, sow them, and then supply water. The temperature is maintained at about 25 ℃, covered with white paper and glass. The seedlings will emerge after a month. After emergence, the white paper and glass will be uncovered without topdressing. After growing for a year, the seedlings will be divided into pots

3、 Common diseases and insect pests

Common diseases and pests of cactus include anthrax, scale insects and whiteflies. Generally, ventilation should be strengthened, water should be controlled, and medicine should be sprayed in time after diseases and pests are found
