摘要
分析了苜蓿草产量和品质构成因子对株丛密度(播种量)、施肥(N、P、K)、刈割制度、利用年限(生长年限)及形态发育的响应,阐明了协调苜蓿草产量和品质关系的管理技术。
The influence of plant population (seeding rate), fertilizerzation (N.P.K.), morphological development and cutting regimes on yield components as well as the forage quality of alfalfa was analyzed. Management technique coordinating the relationship between forage yield and quality of alfalfa was elucidated.
