摘要
为进一步探索马铃薯需肥规律,保障马铃薯高产优质,以‘新大坪’为供试材料,采用裂区试验设计,以施钾量为主处理,施锌量为副处理,研究不同钾肥和锌肥处理对旱作马铃薯产量及其性状的影响。结果表明,适量的增施钾肥和锌肥,可改善其结薯量、薯块质量、大薯率等性状,大幅度提高马铃薯的产量,提高其商品价值。不同施钾量和施锌量处理的产量差异达到极显著水平,但钾肥和锌肥的交互效应不显著。综合比较,在施钾量180kg/hm^2+施锌量9.0kg/hm^2处理的马铃薯产量最高;施钾量90kg/hm^2+施锌量9.0kg/hm^2的产量次之。
The objective of this study is to further explore fertilizer requirement pattern of potato and ensure its high yield and quality.In this paper. Split-plot experiment was conducted to study effects of yield and traits in of ‘New Daping’ potato in semiarid area. Potassium was the main treatment in the experiment,and zincwas the secondary treatment.The results showed that moderate application of potassium and zinc could improve tuber number,tuber mass,and large sized tuber rate,greatly increased the yield of potato and increase its commodity value. The different amounts of potassium and zinc application affected the yield very significantly.However,there was no significant difference on interaction between potassium and zinc application.Based on the comprehensive comparison,the potato yield was greatest under the conditions of 180 kg/hm^2 potassium application and 9.0 kg/hm^2 zinc application.The potato yield was next under the conditions of 90 kg/hm^2 potassium application and 9.0 kg/hm^2 zinc application.
