为验证三江平原测土配方施肥TRPF系统在大豆施肥技术上的效果,在田间设置肥料效应试验,应用灰色关联度和方差分析法,对2012年不同施肥量大豆6个主要性状的表现进行了综合分析,为系统的下一步升级做准备。结果表明:测土配方施肥处理(T4处理)的产量,节数、分枝数、单株有效荚数、单株粒数及单株粒重表现最好,与其他处理之间均存在着显著或极显著差异,并且测土配方施肥处理产量最高,与对照相比增产30.32%;常规施肥增产14.73%;低肥处理增产8.43%;高肥处理增产2.17%。关联度分析表明,不同施肥处理大豆的6个性状的关联序表现为,单株荚数>单株粒重>单株粒数>节数>株高>分枝数。因此在测土配方施肥的基础上,可以选用多荚型(或多粒型)品种,来提高品种的产量潜力。
In order to verify the effect of soil testing and fertilization TRPF system on soybean fertilization in the Sanjiang Plain, fertilizer effect experiments were set up in the field and the performance of six main traits of soybean in different fertilization levels in 2012 were analyzed by gray relational analysis and analysis of variance Analysis, preparation for the next upgrade of the system. The results showed that the yield, the number of sections, the number of branches, the effective pods per plant, the number of grains per plant and the grain weight per plant of soil testing and fertilization (T4 treatment) were the best, and there were significant differences between the other treatments Or extremely significant difference, and the soil testing and fertilizer formula had the highest yield, which increased by 30.32% compared with the control; the conventional fertilization increased yield by 14.73%; the low fertilizer treatment increased the yield by 8.43%; the high fertilizer treatment increased the yield by 2.17%. Correlation analysis showed that the correlation sequence of six traits of different fertilization treatments was: pods per plant> grain weight per plant> grains per plant> number of joints> plant height> number of branches. Therefore, based on soil testing and fertilization formula, you can choose more pods (or more grain) varieties, to improve the yield potential of varieties.
