[Abstract](1141) [PDF](410)
On the basis of analyzing the actuality of processing and utilizing bamboo resource and timber in China , the paper explores the existed problems in the development of bamboo timber industry in China .The main problem is that the utilization of bamboo timber lacks in science and innovation .There are four suggestions on the utilization of bamboo timber :①The products of imitation bamboo boards should be continuously consolidated , improved and developed .Imitation bamboo board is not the only product of utilizing bamboo timber .Too many factories producing the same product will cause the competition of price .②Taking bamboo timber and small caliber raw bamboo as major materials to produce various living products and bamboo products , which conforms to peoples life ideas to adorn and return to nature .③Bamboo chemistry is a rising industry and worth further exploration and development .④Emphasize and exert the role of bamboo associations , organize related enterprises , strengthen information and technology exchange to adapt to the new situations after Chinas entry into WTO .

[Abstract](1025) [PDF](293)
In order to understand the conditions of water soluble organic carbon (WSOC), 27 soil samples under Phyllostachys praecox stands in Linan were analyzed .The findings of analysis show that the content of 25 ℃water soluble organic carbon (25 ℃-WSOC )in the soil under Phyllostachys praecox stands is within (0.155 0 0.005 3)gkg-1 and that of 100 ℃water soluble organic carbon (100 ℃-WSOC)within (0.222 0 0.006 3)gkg-1 . The content and percent of WSOC in the soil under Phyllostachys praecox stands are both higher than those in the soil under tea and Chinese chestnut .The coverage measure to increase the temperature of the soil under Phyllostachys praecox stands increases the content of WSOC in the soil .The content of WSOC in the soil having been covered for 5 years in succession is double compared to that in the soil covered for only 1 year .WSOC in the soil under Phyllostachys praecox stands has obvious (P 0.05)very obvious (P 0.01)effects on the content of TOC , toal N , hydrolyzed N , available-P and rapid-K , activities of urease and surcease , Cd , Co , Ni , Pb and Zn in the soil , which indicates that WSOC organic substances have close relationship with the quality of soil .

[Abstract](1921) [PDF](212)
To provide the essential theoretic bases for applying the planting pattern of intercropping trees with medicinal plant in the west part of China , This paper carried through a more embedded study on the illumination characters and its effect on the growth of medicinal plants in trees and medicinal plants intercropping system by setting different popular row spacing grads .The results were as follows:the light intensity daily change on the middle measure spot between the popular rows was a curve with one peak , it was same as the contrast , but the value of light intensity on the peak was lower than the contrast .The light intensity daily change on the measure spot east to the popular rows and west to the popular rows were symmetrical , the former appeared peak in the morning , the latter in the afternoon .The daily average light intensity on the middle measure spot was higher than that on the other measure spots .The daily average light intensity between popular rows decreased with the popular row spacing decreasing .The height growth of Glycyrrhiza uralensis , Platycodon grandiflorum and Pinellia pedatisecta were different when they intercropped with Populus tomentosa .With the popular row spacing decreasing , the fast height growth rate of Glycyrrhiza uralensis decreased from 1.11 cmd-1 on the contrast to 0.45 cmd-1 on the row spacing 3m , the growth rate change of Platycodon grandiflorum was not serious , on the contrary , the fast height growth rate of Pinelliapedatisecta increased from 0.2 cmd-1 on the contrast to 0.37 cmd-1 on the row spacing 3 m .These results indicated that Platycodon grandiflorum .and Pinellia pedatisecta can adapt to environment of intercropping , these two species can be used to intercrop with trees .
