三江平原测土配方施肥TRPF系统的研制与初步应用

Development of TRPF System for Soil Testing and Soybean Fertilization Recommendation in Three River Plain

研制了主要针对三江平原地区土壤状况的测土配方施肥软件TRPF,并以此软件为基础,通过肥料效应试验,应用方差分析,对5个施肥处理的大豆农艺性状和产量进行了综合分析,以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。结果表明:基于TRPF系统施肥处理的鲜重、株高、荚数、粒数等农艺性状表现最好,与其他处理间存在显著或极显著差异;并且其产量最高,较对照增产30.32%,其次是常规施肥处理,高肥处理增产幅度最小。数据分析显示TRPF施肥处理对大豆增产效果明显,为下一步软件的完善与升级做了有利保证。

The TRPF software of soil testing and fertilizer recommendation had been developed,which aimed at soil conditions in Three River plain. Base on the software, agronomic traits and yield of soybean were made a comprehensive analysis in differ-ent fertilization treatments through fertilizer effect experiment. The fresh weight, plant height, pod number and seed number of fertilization treatment from TRPF were significantly higher than other treatments. The yield of TRPF treatment was the highest, which increased by 30.32% compared with CK, followed by conventional fertilization, the yield of high fertilizer was the least. Results showed that the TRPF treatment had significant yield-increasing effect on soybean,which laid the foundation for perfec-ting and upgrading of the software.
