| 摘 要： | 为探讨叶面肥美加富（Megafol）对水稻的施用效应和合理使用方法，通过多点大田试验，比较研究了喷施叶面肥美加富（Megafol）对水稻中后期植株农艺性状和产量构成的影响。设置牛江镇昌梅村飞机垌试验区NJ（Megafol）、君堂镇中安村中安垌试验区JT（Megafol）的大田喷施675 mL/hm2叶面肥美加富（Megafol）的处理和牛江镇昌梅村飞机垌清水CK对照田埂边行20 cm内（第一行）试验区NJ（Marginal）共3个处理。结果表明：水稻破口期喷施叶面肥美加富，可明显促进干物质向谷粒分配。在农艺性状上，JT(Megafol)1试验区水稻的株高(109.76±7.51) cm与JTCK3对照区水稻的株高(82.19±7.29)cm相比较，差异极其显著；JT(Megafol)3试验区水稻的基茎节粗（4.82±0.79 cm）与JTCK3对照区水稻的基茎节粗(3.20±0.42) cm相比较，差异极其显著；JT(Megafol)1试验区水稻的结实率(90.16±3.59)%与NJCK3对照区水稻的结实率(69.24±16.79)%相比较，差异极其显著；JT(Megafol)3试验区水稻的千粒重(23.05±1.56) g与JTCK1对照区水稻的千粒重(20.28±1.20) g相比较，差异极其显著；这使单株实粒数增加，提高水稻的单位产量面积，JT(Megafol)2试验区的理论产量达到(6318.75±130.05) kg/hm2。同时，喷施了叶面肥美加富，能提高植株抗性，收获时绿叶叶面积指数显著高于对照区，NJ(Megafol)3试验区水稻的叶面积指数(34.83±9.41)与NJCK3对照区水稻的叶面积指数(0.09±0.19)相比较，差异极其显著；可见，水稻中后期施用叶面肥美加富收获期其植株各农艺性状及产量构成对照均显著区别于对照；施用叶面肥美加富基本与对照田埂边行20 cm（第一行）试验区域差异不显著。 |

| Abstract: | Foliage fertilizer Megafol,made by Valagro Company of Italy,is a plant growth promoter which is rich in organic nitrogen such as peptide,amino acid etc and microelement like chelating state iron,zinc,manganese and so on.To study the effects and the reasonable usage of foliage fertilizer Megafol in rice,the agronomic characters and yield components of rice in the late-mid period were compared and analyzed trough experiment in multipoint field in this study.Three treatments were designed as follows:675 mL/hm ... |
| Keywords: | foliar fertilizer Megafol leaf area index agronomic characters of rice theoretical yield |
