摘要

The effects of a product containing lignite derived humic acids (Act) on medium and coarse textured soil properties and vegetable yield were verified through a 3-year pot experiment. This work sought to assess if a lignite derived humic acids product may substitute the use of manure considering its effects on soil properties and yields of vegetables. Both humic acids product in single (Actl) and double (Act2) doses as well as manure (FYM) were applied to soil. The plants tested were celery (Apium graveolens L. var. dulce (Mill.) Pers.) for the first two growing periods and leek (Allium ampeloprasum L,) for the last. The influence of Act application on soil properties together with the yield of tested plants was evaluated after each growing period. The results indicated that almost all soil parameters, such as sorption complex characteristics, organic matter quality and dehydrogenase activity, were improved after humic acids application in both soils. Act application also resulted in higher yields compared to others treatment. In the coarse textured soil the biomasses of roots and shoots were higher 3-fold and 4-fold, respectively after Act2 application than in the control, while in the medium textured this difference was about 2.5 fold for both shoots and roots biomasses. Organic carbon and C bound to humic acid contents remained significantly higher than in the control after the 3rd growing period while dehydrogenase activity and basis saturation significant increments were mainly visible after the 1st growing period. The soil quality index (SQI) was calculated and ranged within the treatments in the following ways: for the coarse textured soil, from 0.16 (control), 0.17 (NPK), 0.23 (FYM) to 0.25 (Acts) and 0.29 (Act2), while for medium textured soil, SQI, from 0.19 (control), 0,20 (NPK), 0,24 (FYM) to 0.25 (Actl) and 0.28 (Act2). However, the highest values were noted after a double dose of Act, and the stronger increments in soil properties occurred in the coarse textured soil versus the medium textured, demonstrating that the humic acids addition to the soil was especially effective in coarse textured, poor soils.

Var。Dulce（磨机。）。）最后两个生长期和韭菜（葱属ampeloprasum L）。每次生长期后，评价ACT应用对土壤性质的影响以及经测试植物的产量。结果表明，几乎所有土壤参数，如吸附复合特征，有机物质量和脱氢酶活性，在两种土壤中腐殖酸均得到改善。与其他治疗相比，ACT应用也导致产量更高。在粗糙的纹理土壤中，在ACT2施加之后，分别在控制中的根部和芽的生物量和4倍，而在介质中，造型的这种差异为约2.5倍，两种射击和根生物量约为2.5倍。在第三个生长期后，有机碳和C与腐殖酸内容物结合的含量显着高于对照，而脱氢酶活性和基础饱和度在第1期后主要是可见的。土壤质量指数（SQI）以下列方式计算并在治疗中进行：对于粗糙纹理土壤，从0.16（对照），0.17（NPK），0.23（FYM）到0.25（ACT2）（ACT2）（ACT2） ，而对于中纹理土壤，SQI，0.19（控制），0,20（NPK），0,24（FYM）至0.25（ACT1）和0.28（ACT2）。然而，在双剂量的行为后，在粗糙纹理土壤中发生的粗糙纹理土壤性质的较强增量较高，表明土壤中的腐殖酸在粗糙的纹理，土壤中特别有效。
