1. Temperature: it is more drought resistant, but when the curing temperature is higher than 15 ℃, the growth state of the plant is obviously better than that of the plant grown in the low-temperature environment. If the temperature is lower than 10 ℃, the growth of the plant will be affected. If the temperature is lower than 0 ℃, the plant will be frostbitten, and if it is serious, it will be frozen to death.
2. Watering: the place with low annual rainfall of 1500 ml needs to be watered once a week, and each time, the water should be watered until the water flows out. If the plant grows in a dry place for a long time, it is easy to develop poorly.
3. Fertilization: it is more resistant to barren, and the consumption of nutrients is not so large. However, it is necessary to supplement nutrients during the growth period, so as to promote growth and increase yield. In the seedling stage, we need to use compound fertilizer once to promote the growth of all aspects of the plant. In the growth stage, we need to apply thin fertilizer once a month to it to supplement nutrition and strengthen the resistance.
4. Light: it can't grow without light. It has a large demand for light. The daily light time is at least five hours.
1. Propagation: it can be propagated by seed propagation. The sowing time is from February to March every year. Dig a ditch on the soil to be planted, mix the seeds and fine sand according to the ratio of 1:2, and then sprinkle them into the ditch, cover with thin soil, water once enough water, about a week to ten days, you can sprout.
2. Medium tillage: after the successful planting, medium tillage is needed. At the same time, loose soil is needed to avoid soil hardening, which will affect plant respiration and hinder growth.
1. Insect damage: there are mainly land tigers, aphids and other pests, which will damage the leaves of plants. Dichlorvos and dimethoate milk can be used for spraying treatment.
2. Disease: the most important disease of the plant is root rot, which will cause the root system of the plant to rot, so that the plant will dry up and die. Usually it needs to do a good job of water management, to avoid soil water, when the disease can use 100 bacteria to clear the root treatment.
1. Edible: it can not be used, but can be used as medicine.
2. Other functions: in addition to being used as medicine, it can also be processed into feed for herbivores.
