Chow) being domesticated in Ganzi prefecture was studied. [Method] The research trial was carried out in the following three kinds of habitats at the same time: the plastic greenhouses, the birch forest of shady slope and the shrubbery of sunny slope, and the results were analyzed with group data average hypothesis test method. [Result] The overall tuber(the juvenile tuber, the immature tuber and the mature tuber) yield and the mature tuber yield were both very significantly higher in the plastic greenhouses than in the other two types of habitats, and respectively reached 9.52 and 6.70 kg/m2; the mature tuber drying rate was dramatically or very dramatically lower in the plastic greenhouses than in the other two types of habitats, and was 23.84%; the stabilities of the overall tuber yield, the mature tuber yield and the drying rate were all reduced in the order of greenhouses, birch forest and shrubbery; and the dry mature tuber yield of the plastic greenhouses was the highest in the three kinds of habitats, and was 1.60 kg/m2. [Conclusion] A good habitat had to be created or chosen in the domesticating cultivation of the wild Geg in Ganzi prefecture. The preferred choice was the plastic greenhouse, the alternative one was the deciduous broadleaved forest of shady slope. The imitating wild planting of the wild Geg should be done in the warm moist deciduous broad-leaved forest of shady slope.展开更多

GM008, Saccharum arundinaceum Retz. cv. GM003, Saccharum arundinaceum Retz. cv. GM002, which had high content of fiber and high content of energy. The results showed that the annual dry matter content of the three kinds of wild arundinaceum were （25.16±2.45）, （20.47±6.37）, （11.27±0.18） t/hm2, respectively; energy indicators of coarse fiber, hemicelluloses, lignin and heat value of the three test plants were all 20-30% higher than control group. Therefore, the three kinds of herbs had good potential for producing energy.展开更多
