基施有机肥对冬小麦产量及土壤理化性质的影响
Effects of Base Application of Organic Fertilizer on Yield of Winter Wheat and Soil Physical-chemical Properties
摘要
Abstract
Organic fertilizers have been widely used in farmland systems for reducing the adverse effects of fertilizer input on farmland environment and crop yield.A field study was conducted from 2022-2023 with the winter wheat'Jimai 44'as the material,and four experimental treatments including 90%chemical fertilizer+10%organic fertilizer,80%chemical fertilizer+20%organic fertilizer,70%chemical fertilizer+30%organic fertilizer,60%chemical fertilizer+40%organic fertilizer(represented by T1,T2,T3 and T4,respectively)were set,and 100%chemical fertilizer was set as the control(represented by CK)to investigated the effects of fertilizer reduction combined with organic fertilizer on yield components of winter wheat and soil physicochemical properties.The results showed that the content of soil water stability macroaggregates and soil organic matter increased with the increase of organic fertilizer application,and the soil water stability macroaggregates and soil organic matter under T3 and T4 treatment significantly higher than that under CK treatment.Meanwhile,a negatively correlation between soil electrical conductivity and organic fertilizer application was found,and there was no significant difference in soil pH under various fertilization treatments.The yield of winter wheat showed first increased and then decreased trend with the increase of organic fertilizer application,and the highest yield of winter wheat was found under T3 treatment(base fertilizer contained 70%chemical fertilizer+30%organic fertilizer),the number of grains,the number of ears per hectare,thousand grain weight and grain yield of winter wheat under T3 treatment increased by 3.08%,1.21%,5.71%and 10.30%compared to those under CK treatment,respectively.Ultimately,T3 treatment had the best performance in improving the physicochemical properties of soil in wheat fields and increasing the yield of winter wheat based on TOPSIS method of entropy weight method,which can be considered as the recommended fertilization method for winter wheat production in experimental areas.关键词
