作者于1982年进行了二化螟不同卵块密度的为害、损失试验,现将试验方法及结果简报如下,供参考。 试验方法 小区处理 种早、晚稻各一坵,分别作一、三代为害、损失试验。小区面积0.02亩,早稻每小区540丛,每丛8—10株。晚稻每小区384丛,每丛4—5株。小区卵量分别0、1、2、4、8、16块,相当于每亩卵量是:0、50、100、200、400、800块,重复六次,随 The author carried out in 2010 on the Chilo suppressalis different egg density damage, loss test, the test methods and results are summarized below, for reference. Test methods Community early seedling, late rice each one mound, respectively, for one or three generations of damage, loss test. Community area of ​​0.02 acres, 540 rice per plot early rice, each cluster 8-10 strains. Late rice paddy per plot 384, 4-5 strains of each bundle. Area 0,1,2,4,8,16 eggs, respectively, equivalent to the amount of eggs per acre is: 0,50,100,200,400,800 blocks, repeated six times, with
