二年生的白花草木栖休眠越冬后,于翌年三月下旬越冬芽萌发出土,进入营养生长和生殖生长并驾齐驱阶段,有机体增殖很快.这一时期植株体系的营养消长规律和特点,决定着草木栖的供肥性能和种子繁殖系数,有必要加以考察研究.我们于1979年通过系统调查测定,初步探索了草木栖生长第二年自返青至成熟的营养生长规律,所得基本资料整理如下.
Perennial white perennial habitat dormancy after winter, in late March the next winter germination of the overwintering buds, enter the vegetative and reproductive growth and go hand in hand stage, the organism proliferate very fast. The growth and decline of plant nutrition and the characteristics of this period determine the habitat of vegetation We need to study the fertilization performance and the coefficient of seed multiplication.We systematically investigated and determined the law of vegetative growth in the second year of herbivorous habitat growth from maturity to maturity in 1979. The basic information obtained is as follows.
