生长调节剂全精控与缩节胺在棉花上的应用效果比较

Comparison of the Application Effect of Growth Regulators QJK and DPC on Cotton

为深入了解植物生长调节剂“全精控”与“缩节胺”在棉花上的应用效果,以棉花品种宛199为试验材料,采用喷施“全精控”与“缩节胺”进行化控处理,比较分析对棉花株型性状、棉花产量及构成因素、棉花纤维品质的影响。结果表明,全精控与缩节胺均能有效构建棉花合理群体和塑造理想的机采棉株型,对棉花产量和纤维品质影响不明显。虽然“全精控”与“缩节胺”主要成分相同,但全精控为固体片剂易保存、剂量和浓度容易控制,使用更便捷。

This study used the cotton variety of Wan 199 as the experimental material,and the chemical control treatment was carried out by spraying“Quanjingkong(QJK)”and“Mepiquat(DPC)”.Comparative analysis of the effects on cotton plant type traits,cotton yield and constituent factors,and cotton fiber quality.In order to understand the application effects of growth regulators on cotton,The results showed that both QJK and DPC can construct a reasonable population and shape an ideal machineharvested type on cotton,effectively.But had no obvious effect on cotton yield and fiber quality.Although the main components of QJK and DPC are the same,QJK is a solid tablet that is easy to store,easy to control the dosage and concentration,and more convenient to use.
