测土配方施肥对晚稻产量和经济性状的影响

针对田林县农民种田长期过量施用或偏施单一化肥，导致土壤板结，作物产量低、品质下降等状况，进行了测土配方施肥对晚稻产量和经济性状影响的试验。试验结果表明，处理N2P2K，增产效果最显著，产量高达6500．40kg／hm^2，比对照增产2535．15kg／hm^2，增产率为63．93％；以处理N2P2K1经济效益最好，扣除化肥成本后，净收益是13122．60元／hm^2，比对照增收4002．45元／hm^2。说明在晚稻生产上进行测土配方施肥，提高了化肥利用率，降低了生产成本，实现农业增益、农民增收.

Soil tested & formula fertilization's impact on late rice yield and its economic characters

Focused on excessive application and prejudiced fertilization at Tianlin County, which lead to soil hardening, low crop yield and worse quality, an experiment of soil tested ＆ formula fertilization＇s impact on late rice yield and its economic characters was conducted. The results show that the treatment of N2P2K1 will have the best yield-increase effect with 6500.40 kg/hm^2, 2535.15 kg/hm^2 higher than CK with 63.93% increase rate; N2P2K1 will have the best benefit with net-income of 13122.60 元/hm^2, 4002.45 元/hm^2 higher than CK, which means the soil tested ＆ formula fertilization can promote fertilizer use ratio, reduce production cost, and finally realize agricultural benefit and farmers＂ income increase.
