摘要
施肥禁牧区每公顷产干草11947 kg,比不施肥禁牧区每公顷产干草4873 kg,增产145.2%,自然放牧区施肥后每公顷载畜量3.59个黄牛单位,自然放牧区每公顷猪粪尿消纳量14.82 t,狗牙根生长期244 d。为狗牙根牧草开发利用提供依据。
The results showed that the hay yield per hm^(2) was 11947 kg,which was 145.2% higher than the hay yield of 4873 kg per hm^(2),and the livestock yield per hm^(2) was 3.59 cattle units per hm^(2) after fertilization in natural grazing area,in the natural grazing area,14.82 tons of pig manure and urine were consumed per hm^(2),and the growth period of cynodon dactylon was 244 days.It provides a basis for the development and utilization of cynodon dactylon herbage.
