1. Temperature: it likes warm climate, but it can grow in the face of severe cold and high temperature. The demand for temperature is different in different periods. There is little requirement for temperature in seedling stage. The low temperature can bear 15 degrees below zero, and the high temperature can bear 35 degrees. Therefore, it is not necessary to adjust the temperature. The germination temperature should be controlled between 18 degrees and 20 degrees, which has the highest germination rate. When the curing temperature exceeds 25 degrees, the plant's own consumption will increase, and the leaves at the base will turn yellow, and the bulbs will become sparse. Pine, plant quality will be seriously reduced.
2. Watering: the seedling stage is relatively drought resistant. As long as it is not in a long-term drought environment, it does not need to be watered. The corm stage likes a humid growth environment, so it needs to be watered. However, it does not need to be watered at the beginning of the development of the corm. Only when the corm grows to 4cm, it needs to be watered. Each time, it does not need too much water. The soil is completely wet.
3. Fertilization: in the growth period, the consumption of nutrients is very large. According to the composition of fertilizer, the main fertilizer type is nitrogen fertilizer, supplemented by phosphorus and potassium fertilizer. If there is base fertilizer applied in the soil, compound fertilizer should be used when applying fertilizer. In addition, calcium can be added to the soil in an appropriate amount. When applying fertilizer, any kind of fertilizer should not be applied too much. It should be combined so as to achieve nutrition balance. The frequency of fertilization is once a half month.
4. Light: it can't grow without light. The light time of every day must be more than five hours, otherwise it is easy to have bad growth.
1. Propagation: it can be propagated by sowing. First of all, prepare the seedbed, mix the seedbed soil mixed with the base fertilizer, and then put it into the nutrition bowl. Before sowing, you need to water the soil well, and then start sowing after the water completely seeps in. Two seeds are placed in each hole. After sowing, cover the fine soil, and then cover the plastic film, and the seedlings will emerge in a week or so.
2. Pruning: there is no specific way to prune it. You only need to cut off the leaves with poor growth during the growth process.
1. Insect damage: when the plant reaches the heading stage, it is easy to infect the Plutella xylostella, which will cause the plant unable to shoot and affect the yield. It is found that there are Plutella xylostella, can use pyrethroids for disinfestation.
2. Disease: it is easy to have sudden disease. It is better to use sterile soil as seedbed before planting, or use the soil sterilized by lime water to sow again, which can effectively prevent the occurrence of sudden disease.
1. Edible: edible.
2. Other functions: it can be used as medicine.
