【摘要】 用复合氨基低聚糖抗病增产剂在不同区域对小麦、玉米、水稻进行了田间小区试验,结果表明,该制剂浸种或在不同时期喷施,均可使产量增加,小麦增产20.8%,玉米10.6%,水稻15.6%,随机方差分析达到显著或极显著水平。田间调查和考种结果表明,小麦、玉米、水稻的稳粒数和千粒重均高于对照,水稻浸种或喷施的叶绿素含量及干物重高于对照,小麦喷施的花后叶面积比对照高。更多还原

【Abstract】 Co-amino-oligosaccharide pathogenesis-resistance and product-increase reagent (CPPR), which contained amino-oligosaccharide isolated from marine crustacean with biochemical technique, can improve pathogenesis-resistance and product of the crops. Field experiment proved that the yield of wheat, maize and rice increased by 20.8%, 10.6% and 15.6% when treated with CPPR (soaking seeds or spraying). Crops, which treated with CPPR, the grains of per spike and the weight of thousand-seeds of wheat, maize and rice all increased. The content of chlorophyll and dry weight of rice which treated with soaking or spraying were higher than these of control, the leaf area of wheat which treated with CPPR (spraying) increased as well.更多还原
