[Methods] Yougui and Guishen were selected and sprayed onto kohlrabi for 1,2 and 3 times,forming difference treatments.[Results]Spraying the two kinds of silicon fertilizers for different times promoted the growth of leaf length,leaf width and leaf thickness of kohlrabi,improved chlorophyll contents in kohlrabi leaves and corm yield,and adversely affected P. xylostella. Furthermore,higher treatment times led to a more remarkably effect and higher harm to P. xylostella. [Conclusions] In production,spraying silicon fertilizer onto maize for 2-3 times could realize the purposes of improving kohlrabi yield and alleviating damage by P. xylostella.展开更多
