| Abstract: | In this paper, lodging shoots in selective cutting unevenaged plantation of fishscale bamboo located in the Longhekou of Shucheng county, Anhni province, were studied. The results, based on surveying from 1,267 m~2 of 30 plots and 19 sample strips along an investigation line of 3,600 m, showed as follows: 1. The number of lodging shoots in the stands where bamboo shoots sprout thickly or plotting are more than those in which bamboo shoots grow singly or separately; 2. The number of lodging shoots in the opening forest and thin stocked stands resulted by selective cutting are more compared with those in the well distributed bamaoo stands; 3. Lodging shoots grown in the border of stand are more, but less within stands; 4. Lodging shoots grown in the stands protected by shelter-belts are less, otherwise are more; 5. Lodging shoots having mother bamboo with larger diameter class are mere than those with smaller diameter class; 6. The number of lodging shoots in the fertile stands are more, but less in the poor stands; 7. The number of lodging shoots grown in the stands near resident areas are more, compared with those growing in off resident areas. |
