通过田间试验和室内测定,研究了剪秧频率和剪秧强度对甘草茎叶以及根部生长的影响.结果表明:不同时期及不同强度的剪秧对甘草茎叶及根系生长的影响不同,在落叶期进行植株高度1/4的剪秧,茎叶鲜重、干重都明显增加,收获时分别达到了37.40 g·株~(-1)和15.99 g·株~(-1),且不影响甘草根长、根粗、根鲜重和根干重.在落叶期进行植株高度1/4的剪秧,可导致茎叶的超补偿性生长和甘草根部的等量补偿生长,既保证了甘草的产量,又提高了甘草茎叶的饲用价值.

Field experiment was carried out to study the effects of pruning on the growth and development of licorice. The results showed that different spurning intensity in different growth periods have different effects on the growth of stem, leaf and root. During deciduous period, after pruning 1/4 of whole plant,the fresh weight and dry weight of stems and leaves both increased,and reached to 37. 40 g per individual and 15. 99 g per individual respectively, at the same time,the root length, root widths, fresh weight and dry weight of root were all not affected. The results indicated that the proper pruning during deciduous period could lead to over-compensatory growth of stems, leaves and roots of licorices. Both yield and feeding value were insured and increased.
