摘要通过去除枯枝落叶层,研究了枯枝落叶层对茭白新梢出苗和生长的影响。另外三个小区作为对照,保留凋落物层。对芽的出现和生长参数进行了七个月的观察。测量通过凋落物层的光入射。无枯枝落叶层的小区比有枯枝落叶层的小区早一个月左右出现新梢。在去除枯枝落叶层的地块中,当平均枝高为61 cm时,最大枝密度为590 m−2,而在对照地块中,枝密度为316 m−2,平均枝高为71 cm。最大拍摄密度达到三个星期后,在小区凋落物。虽然去除立凋落物显着增加初始拍摄密度,植物生长基本上是可比的,无论存在或不存在的积累凋落物。
ABSTRACT The effects of a standing layer of litter on the shoot emergence and subsequent growth of Zizania latifolia were evaluated by removing the litter layer in three plots. Three other plots were kept as controls with litter layer. Shoot emergence and growth parameters were observed for seven months. Light incidence through the litter layer was measured. New shoots emerged about a month earlier in the plots without litter than in the plots with litter layer. The maximum shoot density in the plots where the litter layer was removed was 590 m−2 at the time when average shoot height was 61 cm, whereas the shoot density was 316 m−2 with an average shoot height of 71 cm in the control plots. Maximum shoot density was reached three weeks later in the plots with litter. Although removal of standing litter significantly increased initial shoot density, plant growth was essentially comparable regardless of the presence or absence of accumulated litter.
