Abstract
In order to explore the effects of one-time base application of combined controlled-release nitrogen fertilizers at different release periods on the growth,yield and soil fertility level of corn,the Zhengda 1689 corn variety was selected and a one-time base application test study of combined controlled-release nitrogen fertilizer with different release periods was carried out in Mayuan Village,Touying Town,Yuanzhou District,Guyuan Municipality.The results showed that controlled-release urea treatments with different release period combinations could significantly improve the growth traits,biomass accumulation and final yield of corn.Among them,the theoretical yield of treatment ① was as high as 17 988.3 kg·hm-2,which was significantly higher than that of other combination treatments.The one-time base application of controlled-release nitrogen fertilizer had a significant yield-increasing effect,and the actual yield of treatment①was also the highest.Economic benefit analysis showed that controlled-release fertilizer significantly increased the output value and production-investment ratio of corn.Treatment①had the highest output value,with a net income of 18 177.8 yuan·hm-2 and a production-investment ratio of 2.07.Soil nutrient test results showed that controlled-release fertilizers had positive effects on regulating soil pH value,reducing total salt content,and increasing the contents of soil organic matter,alkali-hydrolyzed nitrogen,available phosphorus and available potassium.However,the variation ranges of different indicators varied.The comprehensive analysis indicates that controlled-release fertilizers can significantly increase the yield and economic benefits of corn.It is suggested that in actual production,appropriate combinations of controlled-release fertilizers be selected based on soil fertility and the characteristics of corn varieties,and combined with scientific agricultural management measures,so as to give full play to the yield-increasing potential of controlled-release fertilizers and promote the sustainable development of the corn industry.关键词
