提出了转基因抗虫棉病虫草害综合防治的一整套技术:采用新克黄枯浸种制钵,向苗床土表面喷洒新克黄枯液,用内吸型杀虫剂克百威与菜籽饼、新克黄枯液、锌.硼.钾.钙.氨基酸LD、尿素、磷酸一铵及氯化钾混合制成药肥在棉苗移栽时150 kg/hm2、蕾期1200 kg/hm2、花铃期1650 kg/hm2分3次埋施,现蕾后用助壮素与锌.硼.钾.钙.氨基酸每隔10 d喷雾1次,在花铃期施用棉太金2号,在果枝20层时打顶,10 d后施用棉太金3号,8月下旬～9月中旬用杀虫剂2次喷杀斜纹夜蛾,7月中下旬用草甘膦异丙胺盐3000 mL/hm2喷施1次。在江西永修、彭泽和九江进行了该综合防治技术的大面积示范,示范结果表明:3个示范点基本无棉枯萎病、黄萎病和生理性红叶茎枯病发生,棉害虫极少发生,籽棉产量为5046.0～7696.8 kg/hm2,经济效益和社会效益均十分明显。
Put forward a set of technologies for the comprehensive control of transgenic insect-resistant cotton pest and weed diseases: using new ginseng seed soaking pot, spraying new ginseng yellow soil on the surface of the seedbed, using the systemic insecticide carbofuran and rapeseed cake , New grams of yellow liquid, zinc, boron, potassium, calcium amino acid LD, urea, monoammonium phosphate and potassium chloride made from mixed fertilizer in transplanted cotton seedlings 150 kg / hm2, buds of 1200 kg / hm2, Flower boll stage 1650 kg / hm2 3 times buried, budding with mepiquatosin and zinc, boron, potassium, calcium amino acid spray once every 10 d, cotton boll age in the application of cotton at 2 Tomato 20 layers topping, 10 days after the application of cotton too gold 3, from late August to mid September with insecticide Spraying 2 times, in late July with glyphosate isopropylamine salt 3000 mL / hm2 spraying 1 times. The large-scale demonstration of the integrated control technology was carried out in Yongxiu, Pengze and Jiujiang in Jiangxi Province. The demonstration results showed that there were basically no cotton blight, verticillium wilt and physiological stem blight occurred in the three demonstration sites, and the occurrence of cotton pests was very rare , Seed cotton yield 5046.0 ~ 7696.8 kg / hm2, economic and social benefits are obvious.
