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。
Based on the software, TRFF, aiming at the soil condition in the Sanjiang Plain, was developed. Through the fertilizer effect test, the variance analysis was used to analyze the agronomic characters and yield of five fertilized soybean so that Verify Sanjiang plain soil testing formula fertilization TRPF system in soybean fertilization technology. The results showed that agronomic traits such as fresh weight, plant height, pod number and grain number performed best under TRPF system fertilization, with significant or extremely significant difference with other treatments; and the yield was the highest, up 30.32% compared with the control, followed by Is a conventional fertilizer treatment, high fertilizer treatment yield the smallest. Data analysis showed that TRPF fertilization had a significant effect on increasing soybean yield, which was a good guarantee for the perfection and upgrading of the next software.
