摘要/Abstract

摘要： 运用组织转化的理论与方法,对白三叶在不同刈割频度和留茬高度下的叶粗生长率、枯死率、净生产率进行了较为系统的研究。结果表明,白三叶叶组织粗生长率以L区(42天×10.0cm)和H区(28天×10.0cm)最高,分别为18.19kg/ha·d和15.93kg/ha·d;枯死率也以L区最高,为9.91kg/ha·d;而净生产率则以B区(14天×5.0cm)处理最高,为11.01kg/ha·d。

关键词: 采摘, 组织转化, 粗生长率, 枯死率, 净生产率

Abstract: The rate of gross leaf tissue growth, senescence and net preduction for white clover leaf weremeasured at different cutting intensities and frequencies with the tissue turnover theory.Results indicated thatthe rate of gross leaf tissue growth in treatment L (40days×10cm) and H (28days×10cm) were the highest,about 18.19kg DM/ha.day and 15.93kg DM/ha·day respectively.The rate of leaf senescence in treatmentL was the highest,about 9.91kg DM/ha·day, but the rate of net leaf tissue production in treatment B(14days×5.0cm) was the highest, about 11.01kg DM/ha·day.

Key words: Defoliation, Tissue turnover, Rate of gross tissue growth, Senescence rate, Rate of net tissue production
