摘要
进行了施用29%三合一甘蔗杀虫复混肥的试验,在甘蔗全生育期,共施3000 kg/hm2。第1次为基肥,施1500kg/hm2,施肥后65天,对蔗龟等甘蔗害虫防效达76.33%。第2次为追肥,施1500 kg/hm2,施肥后45天,防效达73.08%。该药肥对苗期甘蔗株高、叶数、叶长都有较好效果,其最终产量比29%对照复混肥增产14.85 t/hm2,增产率为24.87%。增产的主要原因是甘蔗有效茎数、茎径和单茎重的增加。该药肥对甘蔗株高影响不大。
Test of 29% Sugarcane Complex Insecticide-fertilizer was conducted with application rate ot 3ouo kg/hm2 during whole growth stages. Efficacy of 76.33% was obtained to control Alisonotum impressicolle （Arrow） 65 days after base fertilization of 1500 kg/hm2, and the efficacy was 73.08% 45 days after top-dressing fertilization of 1500 kg/hm2. The product has preferable growth effect to plant height, stalk number and length of leaf. Yield increase of 24.87% was obtained compared with common compound fertilizers without pesticide ingredients and a total increase of 14.85 t/hm2 in yield was obtained. This was due to increased millable stalks, sugarcane diameter and stalk weight.
