摘要
为优化肥料配方,探索盐源水稻生产最佳施肥方法.本文利用测土配方施肥肥效试验,分析不同处理对水稻株高、穗粒数等农艺性状,水稻籽粒、茎叶氮磷钾含量,水稻产量、产值、纯收益和产投比的影响.结果表明,测土配方施肥区(T1)穗粒数和有效穗个数最多,分别为300.80个和294.00个;空白对照区(T3)最少,穗粒数和有效穗个数分别为202.73个和130.00个.测土配方施肥区(T1)和习惯施肥区(T2)水稻籽粒和茎叶中的氮含量均显著高于T3,钾含量无明显差异.测土配方施肥区(T1)水稻产量、产值和纯收益均最高.开展测土配方施肥能够提高盐源水稻产量和种植效益,此方法建议在未来的水稻种植中大力推广.
Abstract
In order to optimize the fertilizer formula,the best fertilization method for salt source rice production was explored.The fertilizer effect experiment of soil testing formula fertilization was used to analyze the effects of different treatments on agronomic characters such as plant height,grain number per spike,nitrogen,phosphorus and potassium content in rice grain,stem and leaf,and rice yield,output value,net income and yield-input ratio.The results showed that the number of grains per spike and the number of effective panicles were the highest in the soil testing formula fertilizer application area(T1),which were 300.80 and 294.00 respectively,while those in the blank control area(T3)were the least,and the grains per spike and effective panicles were 202.73 and 130.00 respectively.The nitrogen content in grain,stem and leaf of rice in soil testing formula fertilizer application area(T1)and habitual fertilizer application area(T2)was significantly higher than that in T3,but the potassium content had no significant difference.The yield,output value and net income of rice in soil testing and formula fertilization area(T1)were the highest.Soil testing and formula fertilization can improve the yield and planting efficiency of salt source rice,and this method should be vigorously promoted in rice planting in the future.
