为探究水稻肥料效应,采用“3414”设计试验方案,开展了田间小区试验,并采用统计学方法进行试验数据分析。试验结果表明:外施化肥是水稻生长发育不可缺少的,合理配施氮、磷、钾更能提升水稻植物学性状和产量。结合经济效益与产量,当地水稻最佳施肥量为氮(N)28.04 kg/亩、磷(P2O5)6.72 kg/亩、钾(K2O)0.61 kg/亩,N、P2O5、K2O质量比为1.00 :0.24 :0.02,此条件下的水稻产量约为637.33 kg/亩。
In order to explore the fertilizer efficiency of rice, field plot experiment is carried out using the "3414" design experiment scheme, and the experimental data are analyzed by statistical methods. Experimental results show that external application of fertilizer is indispensable for rice growth and development, and rational application of nitrogen, phosphorus and potassium can improve the botanical traits and yield of rice. Combined with economic benefit and yield, the optimal fertilization amount of local rice is nitrogen (N) 28.04 kg/mu, phosphorus (P2O5) 6.72 kg/mu, potassium (K2O) 0.61 kg/mu, and the ratio of nitrogen, phosphorus and potassium is 1.00 :0.24 :0.02, the rice yield under this condition is about 637.33 kg/mu.
