Study on Calibration of Rice Formula Fertilization Effect in Lianshui County
摘要
Abstract
This study aimed to optimize rice cultivation management,validate the accuracy of local formula fertilization,determine optimal fertilization rates,improve fertilization effect and economic benefits,and provide scientific evidence for promoting formula fertilization technology.We conducted a comparative analysis of the effects of no fertilization(CK),conventional fertilization(CF),and formula fertilization(FF)on rice yield,economic benefits and nutrient uptake.The results showed that FF treatment significantly outperformed CK in panicle length,effective panicle number,seed setting rate,and theoretical yield,while showing no significant difference compared to CF treatment.Furthermore,the total nutrient application of FF treatment was reduced by 12.29％ compared with CF,which significantly reduced fertilizer input costs,achieving the highest economic benefit of 6 601 CNY/hm2,with an increase of 406 CNY/hm2 compared to CF.The formula fertilization approach promoted more balanced uptake of nitrogen,phosphorus and potassium,optimized fertilizer application structure,reduced nutrient leaching,and achieved the dual objectives of stable yield improvement and cost-effectiveness.关键词
