| 摘 要： | 采用田间小区试验,以不同比例猪粪、猪粪堆肥、沼渣沼液与无机肥配施,研究其对春玉米光合特性、碳氮代谢关键酶活性、产量与品质的影响。结果表明:有机无机肥配施有利于改善春玉米光合特性,提高玉米功能叶硝酸还原酶(NR)和蔗糖磷酸合成酶(SPS)活性,确保稳产并改善品质,其中,以20%的猪粪堆肥与化肥配施处理效果最好,与施纯化肥相比,其春玉米的叶片净光合速率、蒸腾速率分别提高了13.35%和9.81%,灌浆期NR和SPS活性分别提高了17.96%和9.98%,籽粒中粗蛋白、粗淀粉含量分别提高了30.4%和7.48%,硝酸盐含量降低了49.97%,玉米增产7.94%。 |

| Abstract: | Field plot trial was conducted to study the effect of combination of different organic fertilizer,namely pig manure,manure composting or biogas manure and chemical fertilizer on yield,quality and metabolism of carbon and nitrogen of spring maize.Results showed that all the combinations of organic manure and chemical fertilizer improved the photosynthesis characteristics and enzyme activities of nitrate reductase(NR) and sucrose phosphate synthase(SPS) in functional leaves,and the yields and quality of spring maize.Chemical fertilizer with 20% manure composting showed the best effect,with which the net photosynthetic rate and transpiration rate increased by 13.35% and 9.81%,respectively,the enzyme activities of NR and SPS in functional leaves of spring maize at filling stage increased by 17.96% and 9.98%,respectively,the contents of crude protein and raw starch in spring maize corn improved by 30.4% and 7.48%,respectively,nitrate contents decreased by 49.97% and grain yield increased by 7.94%,compared to those with pure fertilizer application. |
| Keywords: | pig manure fertilizer spring maize yield quality nitrate reductase sucrose phosphate synthase |
