摘要
[目的]为制定土壤节肥高产施肥制度和提高其生产效益提供技术指导。[方法]通过开展肥料试验,采用随机区组设计,对水稻肥料配方进行验证。[结果]配方肥处理的水稻苗数、叶面积系数、产量均高于常规施肥处理和不施肥处理;与常规施肥处理相比,配方肥处理可节本300元/hm2,增效2 520元/hm2;施用配方肥处理的土壤养分变化并不明显。[结论]N∶P2O5∶K2O施用量18∶4∶9的肥料配方符合当地水稻生长过程中的营养需求。
[ Objective ] The research aimed to provide the technical guidance for the establishment of fertilizer application of system fertilizer saving and yield increasing and the improvement of productive benefit. [ Method ] The fertilizer formula for paddy was verified. The trial was completed by field experiment, and was designed with randomized block. [ Result] The leaf number, leaf area coefficient and its yield of the formula fertilizer treatment were higher than the other two treatments. The formula fertilizer treatment could save money 300 yuan per beetar, and increase benefit by 2 520 yuan per hectar compared with the conventional fertilization, but the change of soil nutrient Wash ＇ t obvious. [ Conclusion1 The fertilizer formula of N：P2O5：K2O 18：4：9 could meet the demand of the nutriment during the growth process of paddy.
