Abstract

Abstract: By analyzing and comparing the effects of different sowing depth and soil water content on the seed rate of emergence and seedling growth of Cyathula officinalis, the suitable sowing depth and water content of seedbed soil were explored. The pot experiment was carried out with different sowing depth and soil water content treatments. Water was replenished by weighing, and germination potential, rate of emergence, seedling growth and physiological indexes were determined. The results showed that the sowing depth and soil water content had a significant influence on the seed rate of emergence and seedling growth. The germination potential and rate of emergence were higher when the sowing depth was 0.31~0.61 cm. When the seeding depth was 0.61~0.92 cm, the chlorophyll content of seedling leaves was higher and the stress resistance of seedlings was better. The germination potential and rate of emergence were higher when soil water content was 60.71%. The seedlings grew better when soil water content was 53.35%~60.71%. The seedlings had better stress resistance when soil water content was 38.62%~53.35%. The chlorophyll content in seedling leaves was higher when soil water content was 45.98%~53.35%. The suitable sowing depth of Cyathula officinalis seeds was 0.61 cm. The rate of emergence was higher and the emergence was orderly when soil water content was about 60.71%. After seed emergence, the seedling grew vigorously, the chlorophyll content of leaves was higher, and the seedlings had better stress resistance when soil water content was about 53.35%.

Key words: Cyathula officinalis, soil water content, sowing depth, rate of emergence, seedling growth
