The results show that not only the growth of C. wenyujin in lime soil is possible, but also the biomass, yield of medicinal part, the content of oil from the tuber and its medicinal components are higher than those from red soil. The C. wenyujin from lime soil quickly assumes etiolation during initial growth period. Surprisingly, the lusty leafs of C. wenyujin planted in red soil turn to pale and brown flecks occur in the leafs with the fertilization of N, P, K. It is concluded that C. wenyujin can be planted in lime soil; C.

结果表明:温郁金不但可以在石灰土上生长,而且其药用部位的产量、莪术油的含量及莪术油中主要药用组分β-榄香稀等的含量都较大;石灰土上生长的温郁金在生长前期较快地表现出老叶明显发黄的缺肥症状,而红壤植株在追加N、P、K 3种大量元素后功能叶子呈现黄白色,且夹带有褐色斑点的缺肥症状;石灰土中Fe元素有效态含量比红壤低一个数量级,但在石灰土上种植的温郁金植株其Fe元素含量并不比红壤上的低。

First, some critical problems in crystal growth like crystal seeding, Zn dephlegmation, geometrical selection and temperature fields are discussed in theory, and the possible kinds of defects appeared in crystal growth progress and the reasons are carefully researched. To control the concentration of Cd vacancies, a new method by which the Cd vacancies were compensated with excess Cd in the Cd rich starting materials has been developed, and a new kind of two-area tube furnace with good linear temperature distribution was designed.
