摘要

本研究旨在研究腐殖酸和NPK肥料（15:15:15）对红辣椒生长和产量的影响，以获得最适合生长和产量最好的腐殖酸和NPK肥料组成。该研究采用了五个重复的随机区组设计。试验处理为腐殖酸和NPK肥料的组成：100%腐殖酸；75%腐殖酸+25%NPK；50%腐殖酸+50%NPK；25%腐殖酸+75%NPK；和100%NPK。植物生长和产量的数据通过方差分析进行处理，平均值使用Fisher最小显著差异检验进行比较。此外，通过将取自植物样品或土壤样品的叶子混合到一个同质样品中，综合测定了植物生化和土壤化学参数的数据。结果表明，用100%腐殖酸处理的植物与用100%NPK处理的植物相比，生长和产量没有显著差异。与100%腐殖酸相比，施用不同比例的腐殖酸/NPK可使植物叶绿素含量提高65%-82%，总糖含量提高28%-71%。施用腐殖酸/NPK通过提高土壤pH值以及N、P和K来提高土壤肥力。在腐殖酸/NPK+施用25%腐殖酸+75%NPK肥料的组合中，获得了最佳的生长和产量。因此，为了辣椒种植的可持续性，腐殖酸的使用需要随着腐殖酸用量的增加而减少NPK肥料的用量。

Combining humic acid with NPK fertilizer improved growth and yield of chili pepper in dry season

This research aimed to study the effect of humic acid and NPK fertilizer (15:15:15) on growth and yield of red chili, and to obtain the most suitable composition of humic acid and NPK fertilizer which gave the best growth and yield. The study used a randomized block design with five replications. The treatments tested were the composition of humic acid and NPK fertilizer: 100% humic acid; 75% humic acid + 25% NPK; 50% humic acid + 50% NPK; 25% humic acid + 75% NPK; and 100% NPK. Data on plant growth and yield were processed by Analysis of Variance, and means were compared using Fisher’s Least Significant Difference test. In addition, data on plant biochemical and soil chemical parameters were determined compositely by mixing leaves taken from sample plants or soil samples into one homogenous sample. Results showed that there was no significant difference in growth and yield of plants treated with 100% humic acid in comparison with those plants treated with 100% NPK. However, in comparison with 100% humic acid, the application of different ratios of humic acid/NPK increased plant chlorophyll contents by 65% - 82% and total sugar by 28% - 71%. The application of humic acid/NPK increased soil fertility by improving soil pH as well as N, P and K. In the combination of humic acid/NPK, the best growth and yield were obtained with the application of 25% humic acid + 75% NPK fertilizers. Therefore, for the sustainability of chili cultivation, the use of humic acid needs to be accompanied with NPK fertilizers at a reduced amount, along with the increase in the dose of humic acid.

期刊介绍： Advances in Horticultural Science aims to provide a forum for original investigations in horticulture, viticulture and oliviculture. The journal publishes fully refereed papers which cover applied and theoretical approaches to the most recent studies of all areas of horticulture - fruit growing, vegetable growing, viticulture, floriculture, medicinal plants, ornamental gardening, garden and landscape architecture, in temperate, subtropical and tropical regions. Papers on horticultural aspects of agronomic, breeding, biotechnology, entomology, irrigation and plant stress physiology, plant nutrition, plant protection, plant pathology, and pre and post harvest physiology, are also welcomed. The journal scope is the promotion of a sustainable increase of the quantity and quality of horticultural products and the transfer of the new knowledge in the field. Papers should report original research, should be methodologically sound and of relevance to the international scientific community. AHS publishes three types of manuscripts: Full-length - short note - review papers. Papers are published in English.
