中国农科院植保所、湖南农业大学植保学院研究人员采用感虫水稻品种TN1,设置3种施硅水平,即高硅(0.32g Si/kg土壤)、低硅(0.16g Si/kg土壤)和不施硅对照(0g Si/kg土壤),研究了施用硅肥对稻纵卷叶螟产卵和取食选择性的影响。结果显示,稻纵卷叶螟幼虫对硅处理水稻叶片的取食选择性和成虫在硅处理水稻上的着卵量、着卵率均显著低 Researchers at Plant Protection Institute of Chinese Academy of Agricultural Sciences and Plant Protection College of Hunan Agricultural University adopted three rice varieties, rice sensitive to insects and insects, namely, high silicon (0.32g Si / kg soil) and low silicon (0.16g Si / kg soil) (0 g Si / kg soil) were used to study the effects of silicon on the oviposition and feeding selectivity of the rice leaf roller. The results showed that the feeding preference of C. medinalis larvae to silicon-treated rice leaves and that of adults on the silicon-treated rice were significantly lower
