苔菜在蔬菜周年供应中起着不可替代的作用。目前生产中一直沿用经验做法 ,种子产量低 ,品质差。为探索苔菜生长发育规律 ,增加制种产量和效益 ,我们对影响苔菜制种产量的栽培方式、密度和整枝方式进行了研究。1　材料与方法试验于 1 998年 9月至 1 999年 6月在临朐县良种场进行 Moss vegetables in the anniversary of the supply of vegetables plays an irreplaceable role. The current practice has been used in production, low seed yield, poor quality. In order to explore the law of growth and development of moss and increase the yield and benefit of seed production, we studied the cultivation methods, density and pruning methods that affect the production of moss. 1 Materials and methods Test from September 1998 to June 1999 in Linqu County seed field
