【摘要】 试验结果表明,用70%吡虫啉水分散粒剂浸种处理棉花种子,处理浓度与发芽势之间存在一定的负相关。在一定浓度处理以内,无明显差异。在高浓度处理下,发芽势和发芽率明显下降,且差异极显著。更多还原

【Abstract】 The experiment indicates that using 70% imidacloprid WG to treat cotton seed,the relationship between treatment concentration and germination force is negatively correlated.Under certain range of treatment concentration,no obvious difference is existed.In high treatment concentration,the germination force and germination percentage decreased obviously.The difference is of great significance.更多还原
