本文介绍了两个模拟过度采摘对白三叶发育和衰老影响的实验报告。生长在温室箱子里的匍匐茎用人工方法重复采摘以模拟连续牧羊的不同强度。在两个例子中实验都持续到匍匐茎上长出11片叶子为止。发现叶片干物质的产量与茎上剩余叶的多少是成比例的。剩余叶从两片减少到一片时,导致侧枝的产生大约减少25％,死亡茎从33％增加到44％,如果茎上没有留下完全展开的叶片,侧枝的产生下降40％,而留下两片叶子时下降较少。生长在草地上的匍匐茎过度牧羊后,通常可剩余一片绿叶,生长点在0～2片之间变化。本实验讨论了在这个范围内保留不同叶量的结果。 This paper presents an experimental report on the effects of two over-simulated picking on the development and senescence of white clover. Stolons growing in green house boxes were picked repeatedly by hand to simulate the different intensities of successive shepherds. In both cases, the experiment continued until the stolons grew 11 leaves. The yield of leaf dry matter was found to be proportional to the amount of remaining leaves on the stem. The reduction of the remaining leaves from two to one resulted in about a 25% reduction in production of the branches and an increase in the dead stem from 33% to 44%, while the production of the branches decreased by 40% without leaving fully expanded leaves on the stem leaving behind Two leaves less decline. Stolons grown on the grass over shepherd, usually can leave a green leaf, the growth point in the 0 to 2 between the changes. This experiment discusses the results of retaining different leaf volumes within this range.
