Introduction And Artificial Cultivation Experiment On6Species Of Garden Bamboos In Guanzhong Area

Bamboo cultivation and utilization in China has a long history, we have kept them asornamental plantings for a long time and developed a deep Chinese bamboo culture. Aboutmore than100kinds of bamboo were used in park and garden construction. Most of themdistribute in Fujian, Jiangxi, Zhejiang and Hunan province, south of the Yangtze. From themiddle of the last century, gardeners and scientists have tried to introduce southern bamboosto northern China. Some species succeed. In this research we introduced6species of4generabamboos include Phyllostachys aureosulcata f. aureocaulis, Phyllostachys bambusoides Sieb.et Zucc. f. shouzhu, Pseudosasa japonica Hibanobambus tranguillans f. shiroshima,Acidosasa venusta, Phyllostachys sulphurea, from Anji bamboo garden in Zhejiang province,Dazu in Sichuan provence an Nanjing Forestry University in Jiangxi provence. Introductionexperiments were setted in Louguantai experimental forest farm in Guanzhong area inShaanxi province. We studied the cultivation measures and the survival rate; Observed andrecorded the each bamboo of biology and growth patterns;Evaluated the winter resistanceperformance and scale insect infection performance of different bamboo species We got someconclusions：（1）spring was the best time to introduce southern bamboos to Guanzhong area.Effective measures should be taken to ensure survival from seedling to management afterplant. The most important thing was protecting root and keeping the water balance of motherbamboo. Irrigation and storm drainage should be done in time. Combined with soil loosen andweeding, applying organic fertilizer in winter and active fertilizer in growing season. Preventdiseases and pests, Pay attention to rat and rabbit harm. The measures in this research wereappropriate; the survival rate of each bamboo species was exceeded90%.（2）The peak period and ending period of shooting was different in species. Theleaf-expansion period began from10days after peak period of shooting,20days later itbecame a peak period, ended10days after shooting. There was a significant relationshipbetween shooting period and leaf-expansion period. Phyllostachys aureosulcata f.,aureocaulis, Phyllostachys bambusoides Sieb. et Zucc. f. shouzhu, Pseudosasa japonica andHibanobambus tranguillans f. shiroshima had regular shooting in Guanzhong area, shooting in few plant pits of Phyllostachys sulphurea was not in time. Half of plant pits of Acidosasavenusta had no shoot. Developed bamboo in individual plant pit of Phyllostachys sulphureaand Acidosasa venusta was still in a low level in the third year while the others was in a highlevel. Developed bamboo on unit area became steady, seedlings could be transplanted. Thenew developed bamboo clear bole height of Phyllostachys aureosulcata f. aureocaulis,Phyllostachys sulphurea and Pseudosasa japonica was shorter than mother bamboo inexperiment.(3) Phyllostachys aureosulcata f. aureocaulis, Phyllostachys sulphurea, Hibanobambustranguillans f. shiroshima, Phyllostachys bambusoides Sieb. et Zucc. f. shouzhu grewnormally in winter, had no significant winter injury, Parts of leaf of Acidosasa venusta,Pseudosasa japonica lost water and was withered, especially on tip and new developedbamboo. It restored in the next spring. All of the bamboos we had introduced can overwinterin security.(4) The local mainly bamboo scale insect were Antonina crawii, BambusaspisHemisphaerca, Physeriococcus SP and Nesticoccus sinensis. They could not harmPseudosasa japonica and Hibanobambus tranguillans f. shiroshima, Phyllostachysbambusoides Sieb. et Zucc. f. shouzhu and Acidosasa venusta had strong resistance onbamboo scale insect. Phyllostachys sulphurea and Phyllostachys aureosulcata f. aureocauliswere harmed seriously.
