Influence of Batocera horsfieldi on Wood Quality of Five-year-old Populus deltoides × P.nigra cv.Chile;

Nankang Poplar and evergreen poplar are new fast-growing tree species of new varieties selectively breeded out in recent years.

The photosynthetic characteristics of evergreen poplar and Nankang poplars with 6-year old on dry season and rainy season in Panxi dry valley had been studied.

247) was selected as the model of standard volume table for southern type of poplar, which is the two—way volume table compiled according to it i.

Based on classification and combining site conditions and forest densities for southern type of poplar, the cultivation objective and age limit of industrial matcria forests were studied quantitatively in accordance with investigation data at 10 counties and cities of Hubei province of forest stand in 31 standard plot.

According to realistic specialty in plantations for southern type of poplar in Hubei province and detailed data from 31 sample plots, the optimal management density was explored in this paper by using dynamic programming method on the basis of the secondary effect of density model.
