笔者1996年开始按许多资料上介绍的,在6～7月播种德国报春,但连续两年均未成功,每到炎夏酷热时,小苗就渐渐枯死了。我通过仔细观察和分析,认为小苗死掉的原因主要是6～7月正值酷热的夏季,而小苗根细、根少,不耐高温,所以就慢慢枯死了。后笔者根据德国报春性喜凉爽、湿润的特点,改在3月初至4月上、中旬播种,出苗及生长良好,11月底至12月初,便孕蕾,一直延至翌年4～5月还开花不断。
The author began to press many information on the introduction in 1996, to sow in Germany Primula, but for two consecutive years unsuccessful, hot summer, the seedlings gradually died. Through careful observation and analysis, I thought that the reason that the seedlings die is that the summer is hot in June and July, and the seedling root is thin, the root is small and the temperature is not high enough, so it dies slowly. After the author according to Germany Primula Xixi cool, moist characteristics, change in early March to April, the mid-sowing, emergence and growth of good, from late November to early December, then pregnant bud, until April the following year to May also blossom Constantly.
