稀土元素对胡麻生长发育的影响

THE INFULENCE OF RARE EARTH ON GROWING OF LINUM USITATISSIMM L.

喷施稀土液对胡麻营养生长和经济性状影响的研究结果表明，喷施５００ｍｇ·Ｌ－１以内稀土液促进根系生长．在３００～５００ｍｇ·Ｌ－１时提高植株高和工艺长度，且茎粗和分茎数明显增加，３００～４００ｍｇ·Ｌ－１时增加叶密度和叶面积，提高叶绿素的含量３００～５００ｍｇ·Ｌ－１时明显增加分枝数和株果数，千粒重和株粒重显著提高．

The infulence of rare earth upon the vegetative growth and economic character of Linum usitatissimm L. was studied, the result shows that application of earth in500 mg·L-1 concentration promoted the growth of root system, when 300-500 mg·L-1 concentration is used, the plant height,technological length, the stem thick andbranches were increased.
