摘要:

为探明不同种类有机肥对紫薯产量和品质的影响,于2023年在泰安市农业科学院试验基地开展试验,以‘泰紫薯1号’为供试甘薯品种,设不施肥、单施化肥、化肥减量50%分别与猪粪、牛粪、羊粪、鸡粪有机肥配施,共6个处理,分析各处理对紫薯农艺性状、干物质分配、产量和品质的影响。结果显示:猪粪处理的紫薯茎粗最粗,为14.95 cm,较单施化肥处理增加15.71%;羊粪处理的地上部干重最重,为197.62 g,较单施化肥处理增加30.33%;牛粪处理的块根干物质分配比例最高,为71.82%,较单施化肥处理提高11.47%;猪粪处理紫薯的块根产量和商品薯率最高,分别为48607.95 kg/hm2和79.25%;猪粪处理紫薯的块根可溶性糖含量最高,为38.75 mg/g,显著大于其他处理。研究表明,猪粪与化肥配施能促进紫薯地上部与地下部协调生长,促进干物质的合理分配,进而提高商品薯数量、商品薯率、单株薯重、产量和可溶性糖含量,效果优于其他有机肥与化肥配施。研究以期为紫薯的优质高产栽培技术提供理论依据。

Abstract:

To investigate the effects of different organic fertilizers on the yield and quality of purple sweet potatoes, a field experiment was conducted in 2023 at the experimental base of Tai’an Academy of Agricultural Sciences using ‘Taizishu 1’ as the test sweet potato variety. Six treatments were designed, including no fertilization, single chemical fertilizer, and 50% reduced chemical fertilizer combined with pig manure, cow manure, sheep manure, and chicken manure. The study analyzed the impacts of these treatments on agronomic traits, dry matter distribution, yield, and quality of purple sweet potatoes. The results showed that the purple sweet potato stem treated with pig manure had the thickest diameter, at 14.95 cm, an increase of 15.71% compared to the single chemical fertilizer treatment; the aboveground dry weight of sheep manure treatment was the heaviest, at 197.62 g, 30.33% higher than the single chemical fertilizer treatment; the proportion of dry matter distribution in the tubers treated with cow manure was the highest, at 71.82%, which increased by 11.47% compared to the single chemical fertilizer treatment; the yield and commodity rate of purple sweet potato tubers treated with pig manure were the highest, which were 48607.95 kg/hm2 and 79.25%, respectively; the soluble sugar content in purple sweet potato tubers treated with pig manure was the highest, at 38.75 mg/g, significantly higher than other treatments. Research has shown that the combination of pig manure and chemical fertilizers can promote the coordinated growth of the aboveground and underground parts of purple sweet potatoes, promote the rational distribution of dry matter, and thereby increase the quantity, rate, weight, yield, and soluble sugar content of commercial sweet potatoes. The effect is superior to the combination of other organic fertilizers and chemical fertilizers. This research provides a theoretical foundation for high-quality and high-yield cultivation techniques of purple sweet potatoes.
