摘要:

肥料减施增效对于保障我国农业的可持续性发展意义重大,研究新型增效复合肥料对水稻养分吸收和产量的影响有助于保障我国粮食安全。采用大田试验,设置常规复合肥料(CG)、增效复合肥料(ZZ)、常规复合肥料减量20%(80%CG)和增效复合肥料减量20%(80%ZZ)4个试验处理,以研究新型增效复合肥料对水稻生长性状、养分吸收和产量的影响。结果表明:与常规复合肥料处理相比,增效复合肥料处理能够增加水稻分蘖期、拔节期、抽穗期、灌浆期和成熟期单株鲜质量、株高、SPAD值和根体积,在成熟期,增效复合肥料处理的水稻单株鲜质量、株高、SPAD值和根体积分别提高了11.71%,1.29%,8.02%和46.48%,增效复合肥料减量20%处理的水稻单株鲜质量、株高、SPAD值和根体积分别提高了2.29%,0.31%,3.70%和4.09%。与常规复合肥料处理相比,增效复合肥料处理能够增加水稻茎叶干物质量和籽粒干物质量的比例分别为24.46%和21.39%。增效复合肥料减量20%处理增加水稻茎叶干物质量和籽粒干物质量的比例分别为6.07%和8.15%。与常规复合肥料处理相比,增效复合肥料处理的水稻茎叶氮含量和籽粒氮含量分别增加了10.68%和36.96%,增效复合肥料和增效复合肥料减量20%处理的水稻茎叶磷含量分别增加了26.51%和11.24%,增效复合肥料处理的水稻籽粒磷含量增加了10.39%,增效复合肥料减量20%处理的水稻籽粒磷含量降低了5.41%。与常规复合肥料处理相比,增效复合肥料处理的水稻茎叶钾含量增加了19.91%,籽粒钾含量降低了15.83%,增效复合肥料减量20%处理的茎叶钾含量降低了6.56%,籽粒钾含量增加了0.62%。与常规复合肥料处理相比,增效复合肥料处理的水稻产量提高了22.02%,且差异性显著,增效复合肥料减量20%处理的水稻产量提高了1.12%,增效复合肥料处理的水稻穗长、穗数、穗粒数、千粒质量和结实率在各处理中为最高。综上,增效复合肥料能够提高水稻各生育期的生长指标,改善水稻的氮素吸收、磷素吸收和钾素吸收状况,提高作物产量,具有较好的增效效果,增效复合肥料减量20%处理与常规复合肥料相比,能够实现化肥减量不减产,值得进一步推广应用。

Abstract:

Reducing fertilizer application and increasing efficiency is of great significance to ensuring the sustainable development of agriculture.Research on the impact of new-type synergistic compound fertilizers on rice nutrient absorption and yield will help ensure the food security.Four treatments which were conventional compound fertilizer(CG),synergistic compound fertilizer(ZZ),conventional compound fertilizer reduction by 20%(80% CG),and synergistic compound fertilizer by 20%(80%ZZ)was set.The results showed that:Compared with the conventional compound fertilizer treatment,the synergistic compound fertilizer treatment could increase the fresh weight,plant height,SPAD value and root volume of rice at tillering stage,jointing stage,heading stage,filling stage and maturity stage.At the maturity stage,the fresh weight,plant height,SPAD value and root volume of rice plants treated with the synergistic compound fertilizer increased by 11.71%,1.29%,8.02% and 46.48%,respectively.The rice plant treated by the synergistic compound fertilizer reduced by 20% treatment increased by 2.29%,0.31%,3.70% and 4.09%,respectively.Compared with the conventional compound fertilizer treatment,the synergistic compound fertilizer treatment could increase the dry matter weight of stems and leaves and the dry matter weight of grains by 24.46% and 21.39%,respectively.The synergistic compound fertilizer treatment to increase the dry matter weight of rice stems and leaves and the dry matter weight of grain was 6.07% and 8.15%,respectively.Compared with the conventional compound fertilizer treatment,the nitrogen content of rice stems and leaves and the nitrogen content of grains under the treatment of synergistic compound fertilizer increased by 10.68% and 36.96%,respectively.The phosphorus content of rice stems and leaves increased by 26.51% and 11.24%,respectively.The phosphorus content of rice grains treated with synergistic compound fertilizer increased by 10.39%,and the phosphorus content of rice grains treated with synergistic compound fertilizer reduced by 20% decreased by 5.41%.Compared with the conventional compound fertilizer treatment,the potassium content in the stems and leaves of rice treated with the synergistic compound fertilizer increased by 19.91%,the potassium content in the rice grains decreased by 15.83%,and the potassium content in the stems and leaves of the synergistic compound fertilizer reduced by 20% treatment decreased 6.56%,the potassium content of grains increased by 0.62%.Compared with conventional compound fertilizer treatment,the yield of rice treated with synergistic compound fertilizer increased by 22.02% and the difference was significant.The yield of rice treated with synergistic compound fertilizer reduced by 20% increased by 1.12%.The rice panicle length,panicle number,grain number per panicle,1 000-grain weight and seed setting rate of rice of synergistic compound fertilizer were the highest among all the treatments.In summary,the synergistic compound fertilizer can improve the growth index of rice in each growth period,improve the nitrogen absorption,phosphorus absorption and potassium absorption of rice,and increase crop yield.Compared with conventional compound fertilizer,the 20% reduction treatment of synergistic compound fertilizer can realize the reduction of chemical fertilizer without reducing production,and it is worthy of further popularization and application.
