以汕优9E048为试材,研究了水稻对稻瘿蚊为害的补偿作用。结果表明,水稻对稻瘿蚊的为害具有很强的补偿能力。标葱数与百丛产量呈高度负相关(r=-09696),与有效穗关系不密切。据此水稻分蘖期喷药防治指标可定为标葱率20%~25%
Taking Shanyou 9E048 as test material, the compensation effect of rice on the damage of rice gall midge was studied. The results showed that rice has strong compensatory power against the damage of rice gall midge. The number of standard onions was highly negatively correlated with the yield per hundred (r = -09696), but not closely related to effective panicles. According to which the rice tillering spray control indicators can be set for the standard rate of 20% to 25%
