播种育苗方式对大棚辣椒、番茄幼苗生长及病毒病发生的影响

不同播种育苗方式试验结果表明：大田直播的辣椒和番茄幼苗株高一致性差，弱苗比例大；辣椒以营养钵直播苗最高；番茄则在处理间的苗高差异不明显。不同处理间病毒病发病株率差异不显著，但大田直播的病情指数显著高于其它处理。大田直播的小区产量显著低于其它处理。

Effects of Sowing and Seedling Propagation Modes on Seedlings Growth of Hot Pepper and Tomato and Occurrence of Virosis in Plastic Shed

The experimental results of different sowing and seedling propagation modes showed that the seedlings of hot pepper and tomato in A treatment which sowed directly in the field were worse in uniformity of plant height and consisted of more weak seedlings;The seedlings of hot pepper in B treatment which sowed directly in nutritive pot were the highest,but the seedlings of tomato in different treatments had not significant differences in plant height.The rate of diseased plants of virosis in different treatments had not obvious differences,but the disease index in A treatment was significantly higher than that in other treatments ,the plot yield in A treatment was remarkably lower than that in other treatments.
