对益母草〔Leonurus artemisia ( Lour.) S .Y .Hu〕作不同肥料水平的田间处理, 考评单株鲜重、地上部分鲜重、分蘖数和长叶速度等生物学特性。 L4( 23) 试验结果表明:( 1) 磷肥对益母草的单株鲜重、地上部分鲜重和分蘖数的影响起主导作用, 氮肥次之, 钾肥影响最弱;( 2) 对益母草的长叶速度, 磷肥起决定性作用, 氮肥、钾肥的影响不明显;( 3) 氮肥能促进叶片中叶绿素的积累。 根据这些结果对益母草的需肥特性进行了讨论。
 

Field investigation of applying various fertilizer to Leonurus artemisia ( Lour .) S .Y .Hu were carried out to examine fresh w eight of single plant and above ground part, tiller number and growth speed of leaves .The test results of L4( 23) indicated :( 1) Pfertilizer has the key influence to fresh weight of single plant and above ground part and tiller number, N-fertilizer is the seco nd and K-fertilizer is the third ;( 2) the growth speed of leaves is determined by P-fertilizer;( 3 ) chlorophyll in leaves is easily accumulated by N-fertilizer .The fertilizer requirement characters of L.artemisia  were also discussed .
