摘要
选用近年来在黑龙江省推广面积比较大并具有代表性的东农42(高蛋白品种)、合丰25(中间型品种)、东农46(高油品种)3个基因型大豆品种作为试验材料,采用盆栽的方式,在每千克土壤施N和K2O各为0.033g基础上,设P1、P2、P3、P44个施P处理(即每千克土壤分别施P2O50、0.033、0.0670、.100g),进行了3个大豆品种产量和品质的研究。结果表明,3个基因型大豆品种在单株产量、品质方面存在着差异。东农42和合丰25以P3处理单株产量和蛋白含量最高,东农46以P2处理单株产量和蛋白质含量最高;3个品种都是P4处理脂肪含量最高。同一处理不同品种间子粒蛋白质含量是东农42>合丰25>东农46;子粒脂肪含量是东农46>合丰25>东农42。
Three soybean varieties of different genotypes widely planted in Heilongjiang Province, Dongnong 42 (high protein variety), Hefeng 25 (middle variety) and Dongnong 46 (high oil variety), were used in this study to determine the impact of different phosphorus rates on their yield and quality characteristics. The soybeans were planted in pots and fertilized with 0.033 g of N and K2O per kg soil, at the same time, four levels of phosphorous treatments were applied, including P1 ,P2,P3 and P4(i.e. , 0,0.033,0.067 and 0. 100 g of P2O5 per kg soil).The results showed that there were significant differences among these three genotypes. The highest single plant yield and protein content were obtained at P3 treatment with Dongnong 42 and Hefeng 25 and at P2 treatment with Dongnong 46. The highest fat content was at P4 treatment. At the same P treatment, the order of protein content was Dongnong 42 〉 Hefeng 25 〉 Dongnong 46, and the order of fat content was Dongnong 46 〉 Hefeng 25 〉 Dongnong 42.
