【摘要】 药肥复合制剂在棉花上的试验结果表明,该制剂对棉花的营养生长、生殖生长及产量均有明显的促进作用,对棉蚜和棉铃虫也有显著的防治效果。每公顷施用药肥复合生物制剂7 500 mL,比常规对照果枝增加1.1个,伏桃增加0.9个,秋桃增加1.1个,单铃重增加0.5g,绒长增加0.3 cm,衣分增加1.1个百分点,产量增加21.8%,对棉蚜和棉铃虫的防治效果分别达到100%和97%,处理间经L S D法比较,施用药肥复合制剂与其他处理比较差异均达到极显著水平。更多还原

【Abstract】 The results of this study indicated that applying 7500mL·hm-2 the preparation of insecticide and biofertilizer to cotton could promote the nutritional and reproductive growth of cotton,increase the yield of cotton and had good insecticidal effect to cotton aphis and bollworm.Compared with the contrast,the number of branches increased by 1.1,the number of summer bolls increased by 0.9,the number of autum bolls increased by 1.1,the weight of sigle boll increased by 0.5g,the length of fibre increased by 0.3cm,the out turn increased by 6.0%,the yield of cotton increased by 21.8%,the death rate of aphis and bollworm was 100% and 97% respectively.The yield of cotton applying the preparation of insecticide and fertilizer increases significantly than that of other treatments by LSD analysis.更多还原
