Abstract：【Objective In view of the industrial difficulties such as cultivar aging，high fruit cracking rate and lagging management technologyinLvliang jujubearea，humic acid（HA）ecologicalfertilization technologywasapplied toregulate waterandfertilizerinjujube production，soas toimprovetheyieldandqualityofjujubeandtheefectofanti-cracking fruit，as well as the economic benefits of jujube production.【Methods δλδλδλδλδλδλδλδλδλ Using Lycium barbarum cv. Mucao as the experimental material，three treatments weredesigned：HAeco-fertilization（TreatmentA），conventionalchemicalfertilization（TreatmentB）， andanon-fertilizedcontrol（TreatmentC）．High-potassiumcompound fertilizer，blackhumicacidbioorganicfertilier， yellow-brown humic acid potassium organic fertilizer，andacompoundanti-racking agent were applied. Systematic evaluations were conductedonjujubetreebiological traits，anti-cracking rates，yield，fruitquality，andeconomic benefits.【Results】HA eco-fertilizationsignificantlyimproved jujube growth.Comparedwith thecontrol，Treatment Aincreased leaflength，leaf width，and leaf thickness by 34.0% ， 28.0% ，and 36.5% ，respectively. The non-cracking fruit rate reached 68.36% （42.26 percentage points higher than the control），with a yield of 718.6kg per mu （103.7% lincrease）. In terms of quality，Treatment A elevated 100- fruit weight and vitamin C content by 8.3% and 25.0% ，respectively. Net income per hectare reached 16，494.6 yuan，demonstrating significant economic advantages.【Conclusion】TheHA eco-fertilization technologyleverages humic acid’suniquefunctions toregulate water-fertilizerdynamics and synchronizenutrientsupplywith jujube developmental demands.Despite higher initialcosts，futureoptimizations—suchasrefining HA formulationratios，developingcost-effective high-performance agents，and integrating soil improvement measurescould enhance technical synergyand maximizeprofitability in high-efficiency jujube cultivation systems.
