In order to assess the change of triploid populus tomentoza pulp plantation long-term-site productivity, The paper studied on effects of aboveground litterfall, fine root turnover and wet dust precipitation in nutrient cycling of triploid populus tomentoza pulp plantations at different ages,namely 2a色色日韩欧美网站、4a66J8在线视频免费看、5a、6a.It studied influence of different factors on decomposition of leaf一级A片高潮用力啊、tree bark and twig of triploid populus tomentoza to select the operations to accelerate the decomposition and nutrient release. Finally, it studied influence of different intercrops on plantation site productivity and the relationship of intercrops and triploid populus tomentoza to select suitable intercrops. The main results as follows:(1)The aboveground litterfall of triploid populus tomentoza increased along with age from 216.03±59.7gm~(-2) at 3a to 482.38±101.3gm~(-2) at 7a, The N returned by litterfall wasl8.38±2.46kg.hm~(-2)a~-121.63±2.25kg.hm~(-2a~-139.51±4.61kg.hm~(-2a~-138.89±4.89kg.hm~(-2a~(-1) at 3a亚洲爱爱视频、5a、6a亚洲日韩久久久精品2021、7a respectively.

The leaf was the principal pathway to return nutrient to soil among litterfall, fine root turnover and wet dust precipitation. The proportion of returned N by leaf was 74.84%日韩在线成人免费观看、71.96%欧美A人精品综合在线、78.58%、75.03% at 3a91精品国产摄像头、5a成人播放日韩在线观看、6a、7a respectively,The proportion of returned P by leaf was 85.93%99r精品视频只有精品高清8、80.31%天天色色天天、83.04%、83.23% at 3a欧美特级特黄AAAAAA片不卡、5a在线视频青青、6a、7a respectively. Therefore, it is important to protect and utilize the leaf in order to maintenance and enhance the long-term-site productivity of triploid populus tomentoza pulp plantation.
