内蒙古察右后旗马铃薯气候品质认证研究OA

To address the research gap wherein potato quality in cool and cold regions is markedly affected by climatic conditions,with limited existing research on climate quality certification technologies,this study aims to scientifically quantify the comprehensive impacts of climatic factors and enterprise management practices on potato quality,while fully leveraging the advantages of agricultural climatic resources.Focusing on the major potato-producing region of Chayouhou Banner,the research employed meteorological observation data from national basic meteorological stations and the Wulan Hada Sumu automatic meteorological station covering the period 2016-2023,as well as potato quality testing and production management data from 2023,to clarify the suitable meteorological indicators for key potato growth stages(i.e.,sowing-emergence,emergence-branching).By adopting the comparative method and index discrimination method,a comprehensive evaluation model was constructed,encompassing climate suitability zoning(weight=0.3),current-year climatic conditions(weight=0.5),and enterprise planting management level(weight=0.2).The results revealed that the certified region is a climatically suitable area for potato planting(X1=100 points).In 2023,light and temperature resources during the growth period were sufficient(≥10℃accumulated temperature:2672℃;sunshine duration:1527.2 h),precipitation was consistent with the multi-year average(211.6 mm),and periodic drought was effectively alleviated through irrigation measures.The climate resource score was 92 points,with an 6-point deduction due to meteorological disasters(X2=86 points).Enterprise production management level was excellent(X3=95 points),yielding a comprehensive score of 92 points.Thus,the 2023 potato climate quality was graded as"Special Superior",with both appearance quality(tuber uniformity:Grade 1;size:Grade 3)and internal quality(relative starch content:1.2%)meeting the required standards.This study provides technical support for the climate quality certification of potatoes.
