铁锌肥对陇中旱农区马铃薯光合特性和产量的影响
Effects of iron and zinc fertilization on photosynthetic characteristics and yield of potato in semi-arid areas of central Gansu Province
目的 通过大田试验,研究铁、锌肥施用量对马铃薯光合特性、干物质积累分配及产量的影响,以期为黄土高原马铃薯产量的提升提供理论参考和技术支撑。 方法 选用当地主栽品种新大坪为供试材料,处理包括3个施铁量Fe0(0 kg/hm2)、Fe1(10 kg/hm2)、Fe2(20 kg/hm2)和3个施锌量Zn0(0 kg/hm2)、Zn1(20 kg/hm2)和Zn2(40 kg/hm2)。 结果 马铃薯叶面积指数在Fe0Zn2处理下达到最大值,较不施肥提高26.7%;Fe2Zn2马铃薯叶片SPAD值较不施肥提高21.0%;基施铁、锌肥可改善马铃薯光合特性,Fe0Zn2、Fe2Zn0和Fe2Zn2净光合速率较不施肥分别提高54.8%、54.8%、53.0%,产量较不施肥分别提高19.5%、15.0%、21.5%;Fe2Zn2处理马铃薯块茎铁、锌含量达到最大,较不施肥分别增加17.2%、13.8%。 结论 陇中旱农区马铃薯铁、锌肥单施适宜施量分别为20 kg/hm2和40 kg/hm2,配施适宜施量分别为铁肥20 kg/hm2、锌肥40 kg/hm2。
Objective A field experiment was conducted to study the effects of iron and zinc fertilizer application on photosynthetic characteristics, dry matter accumulation distribution and yield of potato, with the aim of providing theoretical reference and technical support for potato yield improvement on the Loess Plateau. Method The main local cultivar Xindaiping was selected as the test material and the treatments included three iron application levels (Fe0 (0 kg/hm2), Fe1 (10 kg/hm2), Fe2 (20 kg/hm2) and three zinc application levels Zn0 (0 kg/hm2), Zn1 (20 kg/hm2) and Zn2 (40 kg/hm2). Result Leaf area index reached its maximum under Fe0Zn2 treatment, which increased by 26.7% compared to no fertilizer.The SPAD value of potato leaves increased by 21.0% under Fe2Zn2 treatment compared to no fertilizer.Basal application of iron and zinc fertilizer improved the photosynthetic characteristics of potato, and the net photosynthetic rate increased by 54.8%,54.8% and 53.0% under Fe0Zn2, Fe2Zn0 and Fe2Zn2 treatments,respectively,and the yield increased by 19.5%,15.0% and 21.5% compared to no fertilizer.The maximum iron and zinc content in potato tubers was achieved in the Fe2Zn2 treatment,with increases of 17.2% and 13.8%,respectively, compared to no fertilizer. Conclusion The appropriate iron and zinc fertilizer application rates for potatoes in the dry farming areas of Longzhong are 20 kg/hm2 and 40 kg/hm2 alone, and the appropriate fertilizer dosage is 20 kg/hm2 for iron and 40 kg/hm2 for zinc in combination.
