播量和品种对紫花苜蓿决策指数的影响
Effects of Seeding Rate and Varieties on Decision Making Index of Alfalfa
摘要
Abstract
To explore the production performance caused by the seeding rate and alfalfa varieties,split plot design was adopted with the seeding rate (15.0,22.5,30.0 kg/hm2) as the main production area,8 different fall dormant classes of alfalfa varieties as subplot.Results showed that:(1) According to the above-mentioned model,the decision making coefficient increased first then decreased as the increase of seeding rate (22.5 kg/hm2>30.0 kg/hm2>15.0 kg/hm2).(2) Based on average dry matter and nutrition value,Concept was put at No.1 priority,followed by WL-525HQ and WL-343HQ.(3) Based on fall dormancy,there was minor difference between fall dormant classes for the decision coefficient.These results suggest that 22.5 kg/hm2,Concept,WL-525HQ and WL-343HQ should be selected in production practice according to the decision making coefficient.关键词
