What are the advantages and disadvantages of autumn sowing and spring sowing of American ginseng?
The advantages of autumn sowing are that the seeds work in a dormant state, which can not be affected by adverse factors, the time from sowing to emergence is long, the soil is well combined, the soil moisture is good, which is conducive to the growth of emergence, and the autumn sowing time is sufficient to ensure the sowing quality. The disadvantage is to prevent drought and cold after sowing, especially in northeast China, the bed surface is easy to harden in spring, which increases the resistance of seedling emergence, and attention should be paid to loosening the bed surface in early spring. The advantage of spring sowing is that it saves the cold protection work after sowing, and the soil is loose and the water is suitable for seedling emergence. However, the spring sowing period is short and the homework is tense. Due to the influence of high temperature, strong sunshine, air drought and spring breeze, young roots are easily damaged, which affects the emergence rate. Under the condition of suitable soil temperature and humidity, the emergence rate of spring sowing is higher than that of autumn sowing.
