测土配方施肥对晚稻产量和经济性状的影响

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

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N2P2K1增产效果最显著,产量高达6500.40kg/hm2,比对照增产2535.15kg/hm2,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/hm2,比对照增收4002.45元/hm2。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。

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.
