Effects of Biomass Nutrient Solution on Wheat Yield,Quality and Soil Fertility
摘要
Abstract
To investigate the effects of biomass nutrient solution on wheat yield,quality,and soil fertility,and to determine its optimal application rate,a field experiment was conducted from 2022 to 2023 in four villages of Tongchuan City,Shaanxi Province,using the wheat cultivar Tongmai 6.Seven fertilization treatments were implemented,including no fertilization(CK),conventional fertilization(NPK),and five levels of biomass nutrient solution at application rates of 3 000 kg/hm2(T1),4 500 kg/hm2(T2),6 000 kg/hm2(T3),7 500 kg/hm2(T4),and 9 000 kg/hm2(T5).Wheat yield,quality parameters,soil fertility indicators,and their interrelationships were comparatively analyzed.The results demonstrated that the biomass nutrient solution contributed to increased wheat yield,with the T3 treatment(6 000 kg/hm2)achieving the highest grain yield of 6 918.65 kg/hm2,representing increases of 18.88%and 4.72%over the CK and NPK treatments,respectively.The application of biomass nutrient solution significantly improved crude protein content,wet gluten content,falling number,and water absorption compared to CK;however,these improvements were not significantly different from those under the NPK treatment.Furthermore,the biomass nutrient solution significantly enhanced soil organic matter,available nitrogen,available phosphorus,and available potassium contents.Correlation analysis revealed that grain yield was significantly negatively correlated with 1000-grain weight,crude protein,wet gluten,grain hardness,moisture content,and falling number,but significantly positively correlated with soil available nitrogen,available phosphorus,and available potassium.In conclusion,under the experimental conditions,the application of biomass nutrient solution improved wheat yield,quality,and soil fertility,with an optimal application rate of 6 000 kg/hm2.关键词
