摘要:

为研究黄腐酸钾、腐植酸钾、生化腐植酸钾对不同水分条件下西葫芦幼苗生长的影响,以西葫芦为试验材料,将3种腐植酸钾与3种水分处理相结合,研究西葫芦幼苗生长、生理及水分利用的响应特征。结果表明,在相同程度水分条件下,与未添加腐植酸钾的幼苗相比,添加腐植酸钾处理的西葫芦幼苗株高、茎粗和叶面积均显著增加,且生化腐植酸钾作用最显著。在同种腐植酸钾作用下,随着水分胁迫程度的增加,西葫芦幼苗抗氧化酶CAT和SOD活性呈增加趋势,水分利用率提高,且生化腐植酸钾处理的幼苗水分利用最充分。综合分析表明,添加腐植酸钾可缓解水分胁迫对幼苗的影响。

Abstract:

To study the influence of potassium fulvic acid (FA), potassium humate (HA) and biochemical potassium humate (BFA) on the growth of zucchini seedlings under different water conditions, with zucchini as the test material, three kinds of potassium humate and three water treatments were combined to study the response characteristics of zucchini seedling growth, physiology and water use efficiency. The results showed that under the same water condition and compared with seedlings without potassium humate treatment, the plant height, stem diameter and leaf area of zucchini seedlings increased significantly under potassium humate treatment, and the effect of biochemical potassium humate was the most significant. Under the action of the same potassium humate, the activity of antioxidant enzymes CAT and SOD in zucchini seedlings increased with the increase of water stress, so did the water use efficiency, and the seedlings treated with biochemical potassium humate had the best water use efficiency. Comprehensive analysis showed that adding potassium humate could mitigate water stress on zucchini seedlings.

Key words: zucchini, humic acid, growth index, physiological property, antioxidant enzyme, water use efficiency
