9種禾本科草本植物的耐旱能力
[Abstract]:Herbaceous vegetation filter belt plays an important role in controlling nitrogen and phosphorus non-point source pollution in farmland, but its growth is easily affected by spring drought in northern China. In order to select suitable grass species for N and P interception grassland, the drought tolerance of 9 perennial candidate herbaceous plants was evaluated by indoor water control experiment. The results showed that: 1) there were obvious differences in growth characteristics of 9 plant materials, the tiller ability of ryegrass (Lolium perenne) and new wheat (Psathyrostachys juncea) was the strongest, and the growth rate of (Elytrigia repens) was the fastest; 2) under drought stress, the tillering ability of 9 plant materials and the stem growth rate at the early stage of the experiment were restricted, thus the biomass was affected, but under moderate and severe drought stress, (Pennisetum alopecuroides), was affected. Under drought stress, the root length of Jingcao 1 and Jingcao 2 were significantly higher than that of other plants. 3) under drought stress, the root length of Jingcao 1 was significantly higher than that of control. The root length and root surface area of switchgrass (Panicum virgatum) increased as compared with the control. 4) the order of drought tolerance of 9 plant materials was Gingcao No.1 (Bromus inermis) Jingcao 1). (Elymus dahuricus) and ryegrass new wheat grass.
