摘要
通过田间多点示范,分析了水稻测土配方施肥的效应。结果表明:与常规施肥区相比,配方施肥区稻谷产量增加了7.1%,土壤贡献率提高了4.6个百分点,施肥量增加了88.5 kg/hm2,但纯收入增加了565.20元/hm2。
The suitable fertilizer application amount, application date and times in rice high - yielding production were studied through field experiment and demonstration. Results showed that the application of soil testing and formulated fertilization technology could increase rice yield and economic benefit significantly. The yield was increased by 7.1 percent, soil contribution rate was in- creased by 4.6 percent, amount of fertilizer was increased by 88.5 kg/hm2, and net income was increased by 565.20 yuan/hm2 as compared with the conventional fertilization.
