摘要

利用腐植酸对改善黄土丘陵沟壑区土壤质量和作物产量具有重要意义。采用腐植酸钾(PH)和黄腐酸钾(PFA)作为土壤改良剂，对陕西省延安市沟壑区进行了土壤改良。通过盆栽试验，研究了两种腐植酸(PH和PFA)对黄土丘陵沟壑区黑麦草生长特性的影响。结果表明，施用腐植酸钾和黄腐酸钾显著提高了黑麦草叶绿素合成和根系长度。当PH和PFA的比例相同时，PFA的效果优于PFH。当腐植酸钾添加量为15g/kg土壤时，叶片叶绿素含量和根系长度达到最大，土壤成熟效果最好。[j] .植物学报，52(2):467-472,2023(6):特刊

Effects of humic acid on chlorophyll content and root length of ryegrass (lolium multiflorum lam.)

Use of humic acid has great significance to improve soil quality and crop yield in loess hilly and gully areas. In the present study, potassium humate (PH) and potassium fulvic acid (PFA) were used as soil amendments in gully the control project area of Yan'an City, Shaanxi Province. A pot culture experiment was conducted to evaluate the influence of two types of humic acid (PH and PFA) on the growth characteristics of ryegrass in the loess hilly and gully area. Results showed that application of potassium humate and potassium fulvic acid considerably increased the chlorophyll synthesis as well as root length of ryegrass. When the proportion of PH and PFA was the same, the effect of PFA was to be found better than that of PFH. When the proportion of potassium humate was 15g/kg soil, the leaf chlorophyll content and root length attained the maximum, and the soil maturity effect was the best. Bangladesh J.

期刊介绍： Bangladesh in situated on the north of Bay of Bengal. Climatically it is a humid subtropical country. Most of the land is deltaic plain of two great rivers, the Ganges and the Bhrammaputra and it tributaries. The country has rich diversity of plants. Main crops cultivated are Rice, Jute, Wheat, Maize, Sugarcane, Mustard and different kinds of Lentils. There are a good number of Public and Private Universities and Plant Research Establishments. Bangladesh Journal of Botany is the official organ of the Bangladesh Botanical Society established in 1972. Since 1972 Bangladesh Journal of Botany is being published regularly. Two issues of the Journal are published, one in June and another in December. Scientific papers (Full paper and short communication) on any field of Plant Sciences from anywhere in the World are considered for publication in Bangladesh Journal of Botany.
