摘要
采用田间小区试验研究了海藻精粉Ⅰ型和海藻精粉Ⅱ型对小白菜株高、SPAD值、植株鲜量的影响。结果表明:施用海藻精粉Ⅰ型和Ⅱ型的小白菜各指标均优于对照,海藻精粉Ⅰ型的株高、叶片SPAD值、植株鲜重分别比对照增加0.71cm、11.72%、12.45%;海藻精粉Ⅱ型的株高、叶片SPAD值、植株鲜重分别比对照增加0.33cm、6.28%、8.17%。
In this paper, the author studied the effects of seaweed powder type Ⅰ and seaweed powder type Ⅱ on plant height, SPAD value and fresh weight of Chinese cabbage by field plot experiment. The results showed that the indexes of type Ⅰ and type Ⅱ of Chinese cabbage were better than those of control. Compared with the control, plant height, SPAD value and fresh weight of Chinese cabbage using seaweed powder typeⅠrespectively increased 0.71cm,11.72%,12.45%, and type Ⅱ respectively increased 0.33cm,6.28%,8.17%.
