摘要
采用与大田生产相似的栽培管理技术方案,以单播为对照,研究了滇东北黑麦和光叶紫花苕按用种量1∶1混播时的锈病发生及危害程度、饲草产量及组成。研究结果表明:混播不能降低锈病的发病率,但可以有效减轻锈病的危害程度,降低因锈病导致的饲草减产损失;混播对饲草产量的增产效应不显著,但可以有效改善饲草品质。
The occurrence and damage degree of rust,forage yield and composition of Rye and Vicia villosa in northeast Yunnan were studied under the condition of mixed sowing of 1∶1,using single sowing as control.The results showed that:mixed sowing could not reduce the incidence of rust disease,but could effectively reduce the damage degree of rust disease and reduce the loss of forage production caused by rust disease;but it can effectively improve the quality of forage.
