不同土壤地力条件下农大豆2号适宜密度与施肥量研究
|
摘要
[目的]研究高产优质抗病大豆新品种农大豆2号在不同土壤地力条件下的适宜密度和施肥量。[方法]采用裂区设计,分别在3种不同土壤地力条件下分析农大豆2号产量及其相关性状。[结果]土壤地力条件不同,施肥量和密度以及二者之间的互作对农大豆2号产量及其相关性状影响不同。在低土壤地力条件下,单株粒数和单株粒重在不同施肥量及密度间的差异达到显著水平,高密高肥处理(密度25.5万株/hm~2,复合肥375 kg/hm~2)的产量较高;中等地力条件下,单株荚数、单株粒数在不同施肥量及密度间的差异达到显著和极显著水平,中密中肥处理(密度18.0万株/hm~2,复合肥225 kg/hm~2)的产量较高;较高地力条件下,不同施肥量及密度间的单株粒重差异达到显著和极显著水平,中密高肥处理(18.0万株/hm~2,复合肥375 kg/hm~2)的产量较高。[结论]该研究为农大豆2号在不同土壤地力条件下高产栽培和大面积示范推广提供了依据。
[Objective]To screen out the suitable fertilizer level and planting density for high yield of a recently released soybean elite variety "Nongdadou 2".[Method]The effects of three fertilizer levels and three plant densities on yield related traits of "Nongdadou 2" were investigated by split plot design in three locations with different soil conditions.[Result]The results showed that yield traits of "Nongdadou 2" affected by fertilizer,planting density and their interactions varies depending on soil fertilizer levels.Under low soil fertilizer,seed number per plant and seed weight per plant were significantly different between treatments,and the yield was highest using the density of 25.5×10~4 plants/hm~2 and the compound fertilizers of 375 kg/hm~2;Under middle soil fertilizer levels,significant differences in pod number per plant and seed number per plant were identified,and yield was highest using the density of 18.0×10~4 plants/hm~2 and compound fertilizers of 225 kg/hm~2;Under high fertile soil,seed weight per plant showed significant variation between treatments,and highest yield was achieved using the density of 18.0×10~4 plants/hm~2 and compound fertilizers of 375 kg/hm~2.[Conclusion]The research results provided practical guidance for the large scale extension of "Nongdadou 2" under different soil conditions.
