You must know that there is a kind of plant in the world. It has an obvious characteristic, that is, when the sun appears, it opens and when the sun sets, it closes. Recently, I heard several people say that they have the idea of planting it, but they don't know what kind of breeding method it is, so they gave up the idea. Today we'll talk about its breeding, so that we don't leave any regrets.

1. Sow

The seeds of this kind of flower are very small. It takes about 8400 seeds to make up the weight of one gram. We usually use the method of Sowing on the seedling plate and covering it with fine vermiculite, or pressing it slightly after sowing the seeds to ensure sufficient water. The temperature of germination is between 21 and 24. It takes about seven to ten days for the seedlings to emerge. The seedlings are very delicate. If they can grow rapidly under relatively high temperature conditions, they can form thicker fleshy leaves later. At this time, the seedlings can be directly moved to the basin. The required basin diameter is about 10 cm. Three or five plants can be planted in each basin. In this way, the seedlings can easily survive and grow at a considerable speed. It is extremely tolerant to the soil, the general soil can adapt, and the sandy soil with good drainage is the most suitable. It can sow seeds by itself to achieve the purpose of reproduction

In addition, it has a long planting time, which is not a problem in spring, summer and autumn. The soil covered should be thin. Of course, it can grow without soil cover. If it is in Sichuan Province, it can be sown in September or October. Before sowing, select an acre of good farmland, and then dig out a deep ditch of about 1.3 meters. The soil for planting it should be very flat and loose. Seeds need to be mixed with human and animal feces to form seed ash. Five or six grams of seeds should be sown per mu. When sowing, you should put some people's fecal water into the ditch, and then disperse the seed ash

2. Cutting

Cutting is usually used for double petal cutting. In summer, the cut branches can be used, and the wilted stem can also be used. After it is alive, there will be flower buds. When it grows, it does not need frequent watering, the fruit will explode when it is mature, and the seeds are easy to disperse, so it needs to be harvested in time. It is mainly seed reproduction, and its self sowing ability is very strong. Since there is a new variety, it is more difficult to collect its seeds. Especially for double petals, the seeds will not seed after flowering. Therefore, the family can adopt the cutting method

3. Ramet

After the summer harvest, dig out the old bags, select the grown plants and divide them into small bags. According to the row spacing of 30 cm, the distance to plant plants is 7 to 10 cm. After that, we need to water livestock manure
