小分子肽氨基酸肥对辣椒生长、产量和品质的影响
Effects of Small-Molecular-Weight Peptide Amino Acid Fertilizer on Growth,Yield and Quality of Pepper
摘要
Abstract
This study used the pepper variety'Xiangla 670'as the test material under drip irrigation under mulch.On the basis of equal conventional chemical fertilizer application,treatments with different concentration gradients of small-molecule peptide amino acid fertilizer(diluted 200-fold,300-fold,400-fold,500-fold,and 600-fold)were set,with distilled water as the control(CK).The effects of this fertilizer on pepper growth,yield and fruit quality were investigated.The results showed that the application of small-molecule peptide amino acid fertilizer significantly promoted pepper growth,yield and quality.At the initial flowering stage,application of the fertilizer diluted 500-fold increased plant height and leaf SPAD value by 12.71%and 8.19%,respectively,compared with CK,while stem diameter and leaf area showed no significant differences.At the full fruiting and harvesting stages,plant height,stem diameter,SPAD value and leaf area all increased first and then decreased with increasing fertilizer concentration,with the optimal concentration being 400-fold dilution.At the full fruiting stage,these indicators in the 400-fold dilution treatment were significantly increased by 10.88%,7.70%,9.09%and 20.52%,respectively,compared with CK;at the harvesting stage,they were significantly increased by 10.68%,9.44%,7.48%and 18.35%,respectively.In terms of yield,the dry yield per plot in the 400-fold dilution treatment was increased by 12.11%compared with CK.Single fruit fresh weight,fruit longitudinal diameter,fruit transverse diameter,pericarp thickness,fruit number per plant,fresh weight per plant and dry weight per plant were all significantly improved,while fruit set rate showed no significant difference.For fruit quality improvement,the 400-fold dilution treatment also performed best,with free amino acid,soluble sugar and vitamin C contents in fruits increased by 22.13%,21.15%and 34.27%,respectively,while soluble protein content showed no significant difference.In conclusion,since the period from full fruiting to harvesting is critical for determining the final yield and market quality of pepper,applying small-molecule peptide amino acid fertilizer diluted 400-fold in production can achieve higher economic benefits.关键词
