本试验针对紫花地丁的生长发育、耐荫性及栽培管理进行了试验观测。结果表明:1.种苗移栽在全荫地,光照强度早、中、晚分别只有全光照的5.9％、8.91％和9.21％的环境下,该草生长欠佳;生长在半荫地环境下,生长旺盛;2.在室温18～26℃进行种子发芽测定,当年和前一年收的种子,分别2～4天萌发,4～6天齐苗,发芽率为93～95％;3.移栽,在保留完全根系和切断2/3根系的对照,保留根系植株在连续3天各一次浇水后返青,成活率98％。10天后长出新苗,15天颈部分蘖;切断根系的植株5天返青,12天长出新叶,18天后分蘖。该试验,对推广利用紫花地丁,具有一定的参考和利用价值。
The test for the growth and development of Violets, shade tolerance and cultivation and management were observed. The results showed that: 1. The seedlings transplanted in the full shade, the light intensity early, middle and late, respectively, only the full light of 5.9%, 8.91% and 9.21% of the environment, poor growth of the grass; growth in semi-shade environment Under the vigorous growth; 2 at room temperature 18 ~ 26 ℃ seed germination determination, the year and the previous year received the seeds, respectively, 2 to 4 days germination, 4 to 6 days Qi Miao, the germination rate of 93 to 95%; 3 After transplanting, while maintaining the complete root system and cutting off the 2/3 root system, the root system was preserved and the green plants were returned to the green after being watered for three consecutive days with a survival rate of 98%. New shoots grew after 10 days, necked and tilted on day 15; plants cut off from the root regrouped for 5 days, new leaves grew up after 12 days and tilted after 18 days. The test, to promote the use of Viola, with a certain reference and value.
