摘　　要：研究不同类型有机叶面肥对江苏盐城射阳盐碱地有机水稻剑叶的叶绿素含量、产量、品质及效益的影响。结果表明,有机叶面肥施用后,剑叶叶绿素含量、产量、品质和效益均高于对照处理。其中大量元素有机叶面肥(处理①),叶绿素含量、稻谷产量和稻米效益均最高;其次为有机碳肥(处理⑤),明显提高了水稻的直链淀粉含量;海藻高钾有机肥(处理④)富含钾和海藻酸植物激素,施用后千粒重最高,但在低氮条件下,产量相比其他有机肥处理增长不大;单一中量元素钙肥(处理③)叶绿素含量、产量和效益均与对照相差不大;鱼蛋白有机肥(处理②)叶绿素含量与处理①和处理⑤无显著差异,但产量低于处理①和处理⑤,且差异显著。不同类型叶面肥平衡施肥提高盐碱地有机水稻产量和品质有待于进一步研究。The study determined the effects of various organic foliar fertilizers on chlorophyll content,yield and economic values of flag leaf for rice in Sheyang County,Yancheng City,Jiangsu Province.The results found that chlorophyll content,yield and economic values were increased with application of organic foliar fertilizers.Among these organic foliar fertilizers,large amount of elemental folia fertilizer(①)showed the best effects with high chlorophyll content,yield and economic values.Next,spraying organic carbon fertilizer(⑤)significantly increased amylose content.The highest thousand grain weight by application of seaweed organic fertilizer(⑥)with high potassium,while yield was not increased significantly compared with other fertilizer at low nitrogen rate.Compared with control,single micro-element fertilizer,calcium fertilizer(③)showed insignificant difference in chlorophyll content,yield and economic value.The chlorophyll content in fish protein organic fertilizer(②)treatment had no significant difference compared with①and⑤,but its yield was significantly lower than①and⑤.Further study is needed to improve the yield and quality of organic rice in saline-alkali soil by balanced fertilization with different types of foliar fertilizer.
