AbstractThe japonica glutinous rice variety Wankennuo 1116 was used as the material，taking the spraying of plainwaterasthecontrol（CK），Fieldexperimentswereconductedtoinvestigatetheefectsofdiffrenttypesoffoliar fertilizers[treatment1，Miaodundun（bio-based）;treatment2，Meizhouxing （nutrient-based）;treatment3，Abscisic acid + Indolebutyricacid （regulation-based）; treatment 4，Liquid enzyme fertilizer（fertilizer-pesticide combination）; treatment5，zhenfengrui combination （composite-based）]onthegrowth period，agronomic traits，yield，andconomic benefitsofrice.Theresultsshowed thatinterms of growth periodandagronomictraits，thetotal growth periodof all treatments was156d，and no significant effect offoliar fertilizers on the growth period was observed.However，the application offoliar fertilizers was found to reduce plant height （109.7-115.6cm）and increase panicle length （16.7- 17.8 cm）.In termsoffactors contributing toriceyieldcomposition，thenumberof paniclesinthe foliar fertilizer treatments ranged from 229 O0O to 276 O00 panicles per 667 m²，the seed seting rate was between 86.1% and 88.5% and the1OOo-grain weight was26.4-27.1g.Therice yieldunder diferent foliar fertilizer treatmentsranged from 696.4to 751.6kgper 667m，withacost-benefitratioof3.4-7.3.Among them，themicrobial foliar fertilizer Miaodundun， the regulatory foliar fertilizer Abscisic acid + Indolebutyric acid，and the compound foliar fertilizer Zhenfengrui combinationdemonstrated beter yield increasingand income enhancing effects.Thisstudyprovidesa reference for efficient fertilization management in rice production.
