- Title:
- Study on Soil and Water Conservation Benefits of Several Grasses
- Keywords:
- grass; tall fescue; Bahia grass; crowfoot; pueraria effect; of soil and water conservation
- 分类号:
- S157;S812.8
- 摘要:
- 研究结果表明：苇状羊茅、百喜草、葛藤、百脉根等4种草被植物可有效增加植被覆盖度，减少土壤容重，增加土壤孔隙度，提高土壤贮水量。茎叶吸水率达到自身重量的39.5%～48.3%，0～20cm土层内直径小于1mm的须根数量分别占总根量的79%、82%、76%和85%，鲜草产量分别达60t/hm2、42.5t/hm2、45t/hm2、23.1t/hm2；保持水土作用强，且具有较高的开发利用价值。
- Abstract:
- Grasses (tall fescue, Bahia grass, crowfoot, pueraria) could decrease soil bulk density, increase the porosity of soil, and enhance the water holding capacity of soil.The water absorption of stem and leaves amounted to 39.5%~48.3% of its own weight.In soil layer 0~20 cm, the amount of small roots that diameter was less than 1 mm was 76~85 percent of total roots, The output of fresh grass were 60t/hm2, 42.5 t/hm2, 45 t/hm2, 23.1 t/hm2.It has considerable benefits of soil and water conservation and ecology.They are excellent feeding grass species for soil and water conservation.
