ABSTRACT
From Table 1 shows that in the whole growing season, the leaf lily each organ biomass on the whole, a trend of first increased after decreased, the maximum (5.59 g) in the middle of July, August, roots and bulbs biomass decline, fruit biomass increasing, biomass accumulation in fruit. The leaf growth early lily, stand is not yet closed, photosynthesis, grow quickly; To flowering (July), the forest canopy closure, the leaf photosynthesis is abate, lily slow accumulation of organic matter. Article 8 months leaf lily, decrease of total biomass fruit biomass increasing. From Table 1 also shows that bulb than the maximum of total biomass distribution, the average is 43.11%, the maximum (60.08%) in early June, the minimum value (17.66%) in late August, from early June to middle of June, from mid-august to late August, bulb biomass were significantly decreased. Cauline leaf biomass proportion is slightly lower than corm, the average is 43.06%, the distribution of the middle of June to August leaf ratio greater than corm, root biomass allocation ratio is consistent with the general trend
1 PROFILE IN THE STUDY AREA
Administration of the study area is located in Jilin province Jiaohe forestry test area, the area is affected by the monsoon temperate continental mountain climate, annual average temperature of 3.8°C. In July, the highest monthly average temperature (21.7°C), the lowest monthly average temperature (18.6°C) in January, frost-free period 100-110 d, annual rainfall of 700-800 mm. For the mountain dark brown forest soil, layers average thickness of 20-100 cm. Belongs to north temperate mixed needle leaf and vegetation, the vegetation diversity of [9].
