摘要:

为了研究不同肥料对甘薯生长的影响,以甘薯‘商薯19’和‘普薯32’为试验材料,研究5种肥料对甘薯‘商薯19’和‘普薯32’的主要农艺性状、产量和品质性状的影响,并进行相关性分析和主成分综合评价。结果表明:‘商薯19’农艺性状相关性分析表明,产量与单株分枝数呈极显著正相关,与最长蔓长、单株结薯数、商品率、干物质率和食味均呈显著正相关;‘普薯32’主要农艺性状相关性分析表明,产量与食味、单株分枝数呈极显著正相关,与干物质率呈显著正相关;‘商薯19’和‘普薯32’不同肥料主成分分析结果一致,均表明肥料N:P:K比例为10:10:23的硫酸钾复合肥600 kg/hm2+生物菌肥750 kg/hm2作为底肥基施最适合甘薯‘商薯19’和‘普薯32’的生长,甘薯的生长性状较好,产量最高,品质最优。

Abstract:

To study the effects of different fertilizers on the growth of sweet potato, the effects of five fertilizers on the main agronomic, yield and quality traits of sweet potato ‘Pushu 32’ and ‘Shangshu 19’ were studied, and correlation analysis and principal component comprehensive evaluation were conducted. The results showed that the correlation analysis of agronomic traits of ‘Shangshu 19’ showed a highly significant positive correlation between yield and branch number per plant, and a significant positive correlation with the longest vine length, number of tubers per plant, commodity rate, dry matter rate and taste; the correlation analysis of the main agronomic traits of ‘Pushu 32’ showed that there was a highly significant positive correlation between yield and taste, branch number per plant, and dry matter rate; the principal component analysis results of different fertilizers for ‘Shangshu 19’and ‘Pushu 32’ were consistent, indicating that 600 kg/hm2 of potassium sulfate compound fertilizer with a N: P: K ratio of 10:10:23 and 750 kg/hm2 of biological bacterial fertilizer as the base fertilizer were the most suitable for the growth of sweet potato ‘Shangshu 19’ and ‘Pushu 32’, with good growth traits, highest yield and best quality.
