“赛肥特”长效剂对黄瓜育苗效果影响初探

摘要

In the test,using peat as matrix,in which added the same amount of KH2（PO4）,Urea,FeSO4,CaCO3 and other fertilizers,and then added the controlled release long-acting agent with different dosages,the application effect of which to cucumber plug seedlings was studied and the results showed： In process B（controlled release long-acting agent 1g）,the plant height and diameter roughness were all better than the other processes and the accumulation effective of dry matter was better,in which could increase leaf area,improve the content of seedlings chlorophyll,increase the ratio of root and crown and the seedling index,so process B was the best process.%在本试验中,以草炭为基质,添加等量的KH2（PO4）、尿素、FeSO4、CaCO3等肥料,再加入不同用量的缓控释长效剂,对其在黄瓜穴盘育苗中的应用效果进行了研究。结果表明：B处理（缓控释长效剂1g）中黄瓜秧苗株高、茎粗均优于其他处理,另干物质积累效果好,可以增大叶面积,提高秧苗叶绿素含量,使根冠比及壮苗指数增大,为最佳处理。
