1： What kind of plant is cactus

Cactus is a pulpy plant of cactus genus in cactus family. It is mostly clustered or shrubby. The stem nodes are flat and obovate, with hard small thorns growing on it, which are brown. As a representative of multi pulp plants, cactus is particularly drought tolerant and is most afraid of ponding. When maintaining at home, keep the basin soil dry, wait until the soil is completely dry, and then water it. If you plant it outdoors, you don't have to manage it. It can grow by day and bloom and bear fruit

2、 Use of cactus

1. Ornamental value: the most common use of cactus should be its ornamental value. It's OK to plant a cactus in a flowerpot and forget to water it occasionally. Anyway, it won't die in drought. It's most suitable for lazy maintenance

2. Edible value: cactus is popular abroad as a food. It has to be said that foreigners have a "iron mouth". Cactus sold in supermarkets are usually pricked. We just need to peel and wash it when we buy it, and then we can fry, steam and fry it

3. Anti theft weapon: cactus is actually a kind of anti-theft weapon, especially in the walls of rural areas in China. If thieves dare to climb the wall, they can tie him into a hedgehog every minute. They regret it

4. Rootstock grafting: cactus is still a very good rootstock. For example, the root system of crab claw is weak, and it is easy to rot if you are not sure about watering. If you graft cactus, you can perfectly solve the problem of rot root by using the drought resistance of cactus
