摘　　要：试验于2018-2019年在中国农业科学院作物科学研究所温室内进行,采用两因素随机区组设计,以土壤类型和追施硼肥为调控因素,研究不同土壤条件下硼肥对小麦产量和晶质的影响。供试土壤分别为黑土、潮土及红土,供试小麦品种为来自埃及的春小麦岛种Egypt New。结果表明:黑土条件下小麦的株高、穗长、穗粒数、千粒重和子粒产量均极显著高于潮土和红土条件下的小麦;黑土条件下小麦的蛋白质及其组分产量最高,潮土次之,红土最低,差异显著;拔节期追施硼肥显著提高了子粒产量。不同处理组合条件下,以黑土和拔节期追施硼肥处理的小麦株高、穗长、穗粒数、千粒重和蛋白产量最高。The experiment was conducted in the greenhouse of Institute of Crop Sciences,Chinese Academy of Agricultural Sciences from 2018 to 2019.The effects of boron fertilizer on wheat yield and quality under different soil conditions were studied using two-factor soil types and boron fertilizer random block design.The tested soils were black soil,alluvial soil and red clay,and the tested wheat varieties were Egypt New,a spring wheat variety from Egypt.The results showed that the plant height,spike length,kernels per spike,1000-grain weight and grain yield of wheat under black soil condition were significantly higher than those under alluvial soil and red clay condition;the grain protein and its yield components of wheat under black soil condition was the highest,followed by alluvial soil and red clay,and the difference was significant;topdressing boron fertilizer at jointing stage significantly increased grain yield.The plant height,spike length,kernels per spike,1000-grain weight and protein yield of wheat treated with boron fertilizer at jointing stage and black soil were the highest under different treatment combinations.
