摘要:
为了促进畜牧业及草业的可持续发展，在施用复合肥、保水剂、蚯蚓粪及秸秆炭的土壤中，种植多年生黑麦草，探究在极端干旱天气条件下，各种物料对黑麦草生长、土壤含水率及其抗旱效果的影响。结果表明：在土壤中施用复合肥、保水剂、蚯蚓粪、秸秆炭后，黑麦草的平均株高（60 d后）分别比未施物料处理增加了20.78%、16.13%、51.16%和43.46%，而黑麦草的地上生物量则提高了42.75%、33.70%、76.09%和60.14%。施用复合肥、保水剂、蚯蚓粪、秸秆炭后土壤有效水分别比未施物料处理提高了16.75%、13.68%、30.63%和20.65%。在持续干旱条件下，蚯蚓粪及秸秆炭施用使黑麦草植株出现永久性枯萎的时间明显推迟了5 d，其抗旱系数比未施物料处理高11.5和9.2百分点，明显地提高了黑麦草的抗旱能力。
Abstract:
In order to promote the sustainable development of animal husbandry and prataculture,perennial ryegrass was planted in the soil applying compound fertilizer,water retention agent,earthworm manure and straw charcoal,the effect various kinds of modifier on perennial ryegrass growth,soil moisture content as well as the drought resistance were explored in extremely dry weather conditions.The results showed that after the application of compound fertilizer in the soil,water retention agent,earthworm manure and straw charcoal,the average plant height (60 days) of perennial ryegrass were increased by 20.78%,16.13%,51.16% and 43.46% than conditioner treatment,and the above ground biomass of perennial ryegrass was increased by 42.75%,33.70%,76.09% and 60.14%.After the application of compound fertilizer,water retention agent,earthworm manure and straw charcoal,soil effective water increased by 16.75%,13.68%,30.63% and 20.65% than giving conditioner respectively.Under the condition of continuous drought,the permanent time of perennial ryegrass delayed 5 d significantly applied the earthworm dung and straw charcoal,the drought resistance coefficient was 11.5 and 9.2 percent point higher than conditioner processing,which improved the droughtresistant ability of perennial ryegrass significantly.
