摘要
为明确不同肥料种类及其相互配合追施提高花生产量的效应,确定适宜的追施肥料种类和相互配施,为花生科学施肥提供理论依据和技术指导。本研究在大田覆膜滴灌条件下,于花针期设置追施氮、钙、硼肥及其相互配施处理,研究了膜下滴灌追肥种类对花生结荚期茎叶干物重、矿质养分吸收和产量的影响。结果表明,花针期追施氮、硼、钙肥及其相互配施均可不同程度地提高花生茎叶干物重、含氮量和积累量、含钙量和积累量、荚果产量,但单独追施氮、硼、钙肥效果不如氮、硼、钙肥配合施用,其中以追施氮硼钙或氮钙提高茎叶干物重、含氮量和积累量、含钙量和积累量、荚果产量的效果好。追施硼肥可提高花生茎秆、叶片含硼量和积累量,而与氮、钙肥配施则可促进花生对硼素的吸收积累。花生产量与茎叶干物重、氮积累量、钙积累量和叶片硼积累量均呈显著正相关关系,茎叶干物重与茎叶氮积累量、茎叶钙积累量均呈显著正相关关系,茎叶氮积累量与茎叶含氮量呈显著正相关关系,茎叶钙积累量与茎叶含钙量呈显著正相关关系,茎叶硼积累量与茎叶含硼量呈显著正相关关系。说明氮硼钙配施促进了花生对氮、硼、钙的吸收积累,增加了干物质量,进而提高了产量。
This study was designed to clarify the effects of different fertilizer types and their mutual application on improving peanut yield,to determine the appropriate type of topdressing fertilizer and mutual application,and provide theoretical basis and technical guidance for scientific fertilization of peanut.Nitrogen(N),calcium(Ca),and boron(B)fertilizer were applied at the pod-pin stage under the condition of mulching drip irrigation in the field and the effects of different types of drip irrigation topdressing on dry matter weight,mineral nutrient absorption and yield of peanut in pod-bearing stage were analyzed.The results showed that the dry matter weight,nitrogen content and accumulation,calcium content and accumulation,and pod yield of peanut stems and leaves were significantly increased by topdressing of N,B,and Ca fertilizer in the pod-pin stage,however,the effect of topdressing of N,B,and Ca fertilizer alone was not as good as that of the combination of N,B,and Ca fertilizer,and the effect of topdressing of N,B,and Ca fertilizer on stem and leaf dry matter weight,nitrogen content and accumulation,calcium content and accumulation,and pod yield was better.Topdressing boron fertilizer could improve the boron content and its accumulation in peanut stems and leaves,while the combination of nitrogen and calcium fertilizer could promote the absorption and accumulation of boron in peanut.Peanut yield and stem(matter weight,nitrogen accumulation,calcium accumulation and leaf boron accumulation)were significantly positively related,stem(stem leaf nitrogen accumulation and leaf weight and the calcium accumulation)were significantly positive correlation,stem leaf nitrogen accumulation and stem leaf nitrogen content were significantly positive correlation,the calcium content in the stem leaf calcium accumulation and leaf were significantly positive correlation,stem leaf boron accumulation with stem and leaf boron content were significantly positive correlation.These results suggest that the application of N,B,and Ca promoted the absorption and accumulation of N,B,and Ca,increased the quality of dry matter,and consequently increased the yield of peanut.
