公路邊坡草灌植被生長(zhǎng)影響因素分析
[Abstract]:The formation of stable community of grass irrigation is the goal of ecological protection of highway slope, but there are few literatures on the influence of sowing quantity and ratio of grass irrigation on the growth of slope vegetation in the aspect of mixed sowing of grass irrigation at present, which is lack of guiding significance to practical engineering. In order to study the effects of seeding amount, ratio of grass to irrigation and ratio of slope to slope on vegetation growth, 48 groups of plots were made by taking Dogyangma and white clover as the representative of herbs and shrubs, respectively. The results showed that the growth of mixed sowing land was better than that of pure shrub land. The optimal ratio of grass to irrigation was 1: 5 for the aboveground biomass of the three plants, and 1: 3 before 25 days for the optimal rate of coverage. The order of the aboveground biomass of the two herbaceous plants was: 30 g / m220g / m215g / m2, and the order of seeding quantity affecting the shrub number Hua Mulan was: 15 g / m220g / m230g / m220g / m215g / m2, the effect of sowing amount on the coverage was 30 g / m220g / m215g / m2, and the later sowing amount had little effect on the coverage. The slope had little effect on the community coverage, but the smaller the slope, the more the aboveground biomass of the plant and the better the community growth.
