Chrysanthemum is a semi-cold vegetable, like cold, not hot, not too cold. Seeds begin to germinate at 5°C, germinate at a suitable temperature of 20 to 25°C, and germinate poorly at temperatures above 35°C. The growth temperature range is 10~30°C, the suitable temperature is 15~20°C, the growth rate is slower than 12°C, the growth rate is above 29°C, and it can tolerate short-term temperature of -2°C to 2°C. It is suitable for cultivation in spring and autumn. Long growth period in autumn, high yield and good quality. The cultivation of spring bloom in North China is usually planted in March-April, and autumn sowing is from late July to early September. The spring is in spring from late February to late March and autumn is from mid-August to early September.
Chrysanthemum plants are small and have a short growth period. In addition to monocropping, they can be interplanted with cabbage, tomato and melons. The land should be fertile, moist, and more lively, withdrawn or broadcast, with a sowing rate of 2~4kg per 666.7m2. In the spring, the best germination should be followed by sowing and sowing. The film should be covered after sowing. After the autumn sowing, it should be shaded with straw and shade nets. Fertilizers were topdressed for 2 or 3 times during growth, each time for 66kg of urea at a rate of 15kg. Winter and spring with plastic greenhouses better cultivation.
30-40 days after sowing, the height of the seedlings began to be harvested at 20 cm. All cuts can be made at one time, or can be divided between seedlings. You can also eat the tender stems; when the seedling height is about 25cm, the stem base leaves 2 leaves to remove the upper part. After the lateral buds grew up and grew, 1~2 leaves were further harvested and the shoots were harvested for 3~4 times. Generally, the yield of 666.7m2 was 1500~2000kg.
