Abstract:

This paper compared the seasonal dynamics of height and biomass of the population Aneurolepidium chinense, which is the constructive species of the artificial grassland, with that of its neighbouring natural community.

1. From the beginning of June to the middle of August, the height increase of the population follows

and the maximum value of the average height reaches 52.98cm; furthermore, its individuals nearly occupy the middle and upper layers of the community; in the natural community, however, the curve of height increase of the population is expressed as and the maximum value of the average height is only 40.61cm.

2. The biomass of the population increases as the following equation

during the growing season, and the content of dry matter in the aboveground parts of plants varies by CA=27.4874+0.2245t. Both the peak of biomass and the maximum content of dry matter are more than those of natural community.

Now the artificial grassland can be used as an area of mowing, and a large amount of grasses of good quality will be harvested from it.
