不同播种期与定植期对高菜留种的影响

以高菜为材料,研究了不同播种期与定植期对其留种的影响,结果表明,病毒病、软腐病的发病株率与病情指数,小区采种株数均表现为处理2与处理3相差不大,且低于处理1;单株有效分枝数、荚果数、种子产量,处理2与处理1相近、明显高于处理3;小区种子产量和折667 m2种子产量,处理2明显高于处理1、处理3。综合认为,10月5~10日播种,11月5~10日定植的高菜留种产量高,质量较好。

Effect of Different Sowing Seeds and Setting Date on Brassica juncea var. Integrifolia

The effect of different sowing date and setting date on seed reserveation of Brassica juncea var.integrifolia were studied.The results indicated that diseased plant rate and sickness index of viral disease,soft rot was processes 2 with processes 3 closely,processes 2 is lower than processes 1;a plot seed collecting number is processes 2 with processes 3 closely,processes 2 is higher than processes 1;the single effective branching number,the pod number,the seed output is processes 2 with processes 1 closely,processes 2 are higher than processes 3;the plot seed output and seed output per 667 m2,processes 2 is higher than processes 1 and processes 3.
