新态植物生长促进液在赣北棉花上的应用研究

Application Study of the“New Status”Plant Growth Promoting Liquid on Cotton in Northern Jiangxi

为了促进"新壮态"植物生长促进液在棉花生产中的应用推广,于2015年在江西九江圩区棉田进行叶面肥、冲施肥在棉花不同生育阶段喷施和滴施的4重复8处理小区试验。结果表明:在赣北棉区的棉花常规栽培模式下,施用"新壮态"植物生长促进液对棉花的生长发育有促进作用,施用次数多和用量偏多的处理效果更佳,尤其在增加产量和减少蕾铃脱落方面效果显著。滴施方法的用工投入和劳动强度均较大,且增收效果不明显,建议改变剂型为粉剂,掺在当家肥中埋施较好或者采取微施肥技术于不同生育阶段喷施。

In order to promote the application and popularization of the ＂New Status＂plant growth promoting liquid in cotton production,the8 treatmentwith4 repeatedplotexperimentsofsprayinganddrippingfoliarfertilizerandpunchingfertil izer in different growth stages of cotton was carried out in 2015. The results indicated：underthecottonconventionalcultivation mode in North Jiangxi cotton area,the application of the ＂New Status＂plant growth promoting liquid had promoting effect on the growth of cotton,moreapplicationtimesanddosagemorebetter,especiallyintheincreasingyieldandreducingtheabscis sion of cotton buds and bolls significantly. The labor input and labor intensity of the drop application method were larger,and the efffect was unobvious. So,it suggested that it can change the formulation liduid to pulvis for applicaton mixed with formal fertilizer,or it can spray fertilizer wiht the micro-application technology in different growth stages.
