怀地黄[Rehmannia glutinosa(Gaertn.)Libosch.ex Fisch.et Mey.]亦称地黄、生地、属玄参科草本植物,原产河南,是常用的中药材。怀地黄引种闽南已有多年历史,能自留繁殖。尽管小面积的千斤高产田时有出现,唯立地环境与原产地相差甚大,大面积亩产一般只有二、三百斤。因此,大幅度地提高单位面积产量确实可能。另外,怀地黄不能重茬,有人还反映怀地黄在闽南会发生品种退化,这也是生产上急待解决的问题。对此,我们进行了试验和调查研究。
Rehmannia glutinosa (Gaertn.) Libosch.ex Fisch.et Mey.] Rehmannia glutinous rice, also known as Rehmannia glutinosa, is a genus of Scrophulariaceae, native Henan, is commonly used in Chinese herbal medicines. Rehmannia Introduced Minnan has many years of history, can keep breeding. Despite the small area of high-yielding fields, there is a great difference between the environment and the place of origin. Generally, there are only two or three hundred jin of large-area mu production. Therefore, it is indeed possible to significantly increase the yield per unit area. In addition, Rehmannia can not be re-cropped, it was also reflected in Rehmannia will occur in southern Fujian varieties degeneration, which is also an urgent solution to production problems. In this regard, we conducted a pilot study and research.
