有机无机肥不同配比对水稻产量及效益的影响

Effects of Organic Fertilizer and Chemical Fertilizer Rates on Yield and Benefits of Rice

为探索有机无机肥不同配比对水稻产量及效益的影响,以有机肥(M)和无机肥含等当量的氮、磷、钾为基础,开展了M_1(NP_2O_5K_2O)0、M_(1/3)(NP_2O_5K_2O)_(2/3)、M_(1/2)(NP_2O_5K_2O)_(1/2)、M_(2/3)(NP_2O_5K_2O)_(1/3)、M_0(NP_2O_5K_2O)1的5个不同配比试验。结果表明:水稻产量表现为M_0(NP_2O_5K_2O)_1产量最高,达531.3kg/667m^2,与M_(1/3)(NP_2O_5K_2O)_(2/3)、M_(1/2)(NP_2O_5K_2O)_(1/2)、M_(2/3)(NP_2O_5K_2O)_(1/3)产量差异不显著,与M_1(NP_2O_5K_2O)_0产量差异达显著水平。水稻产值表现为M_1(NP_2O_5K_2O)_0>M_(1/3)(NP_2O_5K_2O)_(2/3)>M_(1/2)(NP_2O_5K_2O)_(1/2)>M_0(NP_2O_5K_2O)_1>M_(2/3)(NP_2O_5K_2O)_(1/3),M_1(NP_2O_5K_2O)_0产值最高达1760.6元/667m^2,比M_0(NP_2O_5K_2O)_1产值高232.3元/667m^2。根据生产应用可操作性、综合产量、产值和化肥减量分析,以M_(1/3)(NP_2O_5K_2O)_(2/3)效果较好,水稻相对产量较高,产值增加,化肥减量达1/3。

To explore effect of organic fertilizer and chemical fertilizer rates on yield and benefits of rice,organic fertilizer(M)and chemical fertilizer based on the same rates of NPK,M1(NP2O5K2O)0、M1/3(NP2O5K2O)2/3、M1/2(NP2O5K2O)1/2、M2/3(NP2O5K2O)1/3、M0(NP2O5K2O)1were tested on rice.The results showed that the yield of M0(NP2O5K2O)1was the greatest,it’s531.3kg/667m^2,but there isn’t significantly difference among M1/3(NP2O5K2O)2/3、M1/2(NP2O5K2O)1/2、M2/3(NP2O5K2O)1/3,but it’s significantly to M1(NP2O5K2O)0.The benefits of each treatments were follows:M1(NP2O5K2O)0>M1/3(NP2O5K2O)2/3>M1/2(NP2O5K2O)1/2>M0(NP2O5K2O)1>M2/3(NP2O5K2O)1/3,the benefit of M1(NP2O5K2O)0was the greatest,it’s1760.6Yuan/667m^2,which was232.3Yuan/667m^2greater than M0(NP2O5K2O)1.According to production potential,yield,benefits and chemical fertilizer decreasement,M1/3(NP2O5K2O)2/3was the best in these treatments,which has greater yield,increase the benefits,and decrease1/3chemical fertilizer.
