Effects of combined application of organic and inorganic fertilizers on soil nutrients,wheat grain yield and quality based on long-term location

摘要：
为探究不同施肥处理对黄淮海平原农田土壤养分和小麦籽粒产量及品质的影响,在2007年开始的长期培肥试验基础上,于2018年至2020年设置6个处理:在原有常规化肥(+F),化肥和秸秆配施(+FS),化肥和牛粪配施(+FM),以及3种长期施肥处理的基础上各增一个不施肥处理,分别记为-F,-FS,-FM.在小麦成熟期对土壤养分、产量以及籽粒品质进行综合分析,结果表明:+FS和+FM的土壤养分质量分数和籽粒产量以及品质显著高于+F组;连续两年不施肥处理后,与+FS和+FM处理相比,-FS和-FM处理的速效磷质量分数分别下降15%和16%,土壤有机碳质量分数分别下降9.3%和9.9%,产量分别下降3.4%和4.2%,但-FS和-FM处理籽粒蛋白质量分数、湿面筋质量分数和淀粉质量分数并未出现显著下降;-FS和-FM处理的速效磷质量分数、有机碳质量分数、籽粒蛋白质量分数、湿面筋质量分数、淀粉质量分数下降幅度均小于-F处理.因此,在长期培肥基础上,无机有机肥配施的土壤-小麦系统的稳定性更高.

Huang-Huai-Hai Plain is the main grain producing area in China.Environmental problems are becoming the focus of public concern because of the overuse of fertilizers.In order to explore the effects of different fertilization treatments on soil nutrients and wheat grain yield and quality in this area,since 2007,three long-term fertilization experiments were conducted in Huojia county,Henan province in it on the basis of conventional chemical fertilizer(+F),combined application with chemical fertilizer and straw(+FS),combined application with chemical fertilizer and cow manure(+FM),another three treatments that no longer applied any fertilizers on the previous three plots were added,respectively named as-F,-FS and-FM.Soil nutrients,wheat yield and grain quality were measured in the mature stage of wheat.The results indicated that the soil nutrient concentration,grain yield and quality of combined application of organic and inorganic fertilizers treatments(+FS and+FM)were significantly higher than that of the chemical fertilizer treatment(+F).In two consecutive years without any fertilizers,compared with+FS and+FM treatments,the concentration of available phosphorus in-FS and-FM treatments decreased by 15%and 16%,the content of soil organic carbon decreased by 9.3%and 9.9%,and the yield decreased by 3.4%and 4.2%.However,the protein concentration,wet gluten concentration and starch concentration did not decrease significantly in-FS and-FM treatments.In addition,compared with-F treatment,the concentration of available phosphorus,organic carbon,grain protein,wet gluten and starch decreased less in-FS and-FM treatment.Therefore,the soil-crop systems which combined application of inorganic and organic fertilizers indicated much better stability.
