摘要:【目的研究不同缓释肥对贵州春马铃薯生物效应及土裏肥力的影响,为其轻简化栽培及“两减”、“三节”综
合技术集成提供参考。【方法通过田间试验,选择7个类型的缓释肥与普通复合肥进行对比,在相同肥料用量(N240
kg/ha、P2O3120kgha、KO270kgha)条件下研究不同类型缓释肥对贵州春马铃薯产量、结薯性状及十壤肥力状况的
影响。【结果与施普通复合肥(对照)相比,金正大、诺泰克、洋丰和施可丰缓释肥均能显著提高春马铃薯产量(P0.05,
下同),增幅为19.19%6~24.6%6;与对照相比,施缓释肥处理的单株产量和大中薯率分別提高2.6%~73.1%和6.6%~15.1%
以金正大缓释肥效果最佳:而西洋、沃夫特和骅龙缓释肥处理的产量出现显著降低。与对照相比,施用缓释肥处理的
春马铃薯耕层土壤pH、有机质、全氮、碱解氮、全钾和速效钾分别提高3.8%~7.5%、27.1%~59.1%、14.3%~333%、
8.7%6~47.8%、7.0%6-26.3%和8.8%~42.1%,而十壤全磷和速效磷含量分別降低7.19%0~21.4%和35.6%6~58.0%6。【结论缓
释肥在提高贵州春马怜薯产量、改善土壤肥力状况等方面效果明显,但不同缓释肥的作用效果存在差异。综合米看,
以金正大、诺泰克、洋丰和施可丰缓释肥的増产效果最佳,可适当在该地区进行示范推厂

Abstract: ( Objective The present experiment was condueted to study the e feets of different slow-release fertilizers or
biological effect and soil fertility for spring potato in Guizhou, which provided reference for the simplified cultivation, " re-
duce the application of fertilizer and pesticide " and save water, fertilizer and pesticide " comprehensive technology inte
of fertilizer(N 240 kg/ha, P20; 120 kg/ha and K 0270 kg/ha ) were studied. [Resul Compared with control, the slow re-
lease fertilizers Jinzhengda, Nuotaike, Yangfeng and Shikefeng could significantly increase the yield of spring potato by
19 1-24.6%(P<0.5, the same below ) Compared with control, in slow release fertilizer treatments, tuber yield per plant
ncreased by 2. 6%-73.1% and the large and medium-sized tuber percentage increased y 6.6%-15.1%. The effects of

release fertilizers Xiyang, Wofute and Hualong deereased the yield significantly
Compared with the control, application of slow release fertilizer could inerease the soil PH(3.8-7.5%), organic matter

and available potassium(8.8%0-42. 1). ul olal phosphorus and available phosphorus conten decreased by 7.1%0-21.4%
and 35.6%-58.0% respectively. Conclusion]Slow release fertilizers can inerease the yield of spring potato and improve soil
fertility obviously. But the effects of different slow release fertilizers are various. Overall. slow release fertilizersjinzhengda
Nuotaike, Yangfeng and Shikefeng have the optimal yield increasement, and can be promoted in local area
