摘要: 为提高小麦(Triticum aestivum L.)苗期生长的抗逆性,采用单因素试验方法,利用盆栽研究了7个不同浓度(0、1.00、1.25、1.50、2.00、2.50、3.00 g/L)的海藻腐殖酸平衡营养液对小麦幼苗株高、茎粗及各生理指标的影响。结果表明,海藻腐殖酸平衡营养液可以促进小麦幼苗的生长,随着施肥浓度的增加,小麦的株高、茎粗、超氧化物歧化酶(SOD)活性、维生素C含量、脯氨酸含量、可溶性糖含量和叶绿素含量均呈先上升后下降的趋势。综合来看,小麦生长的最适海藻腐殖酸平衡营养液浓度为2.00 g/L。

Abstract: In order to improve the stress resistance of wheat (Triticum aestivum L.) seedling growth, a single factor experiment was conducted to study the effects of seven different concentrations (0, 1.00, 1.25, 1.50, 2.00, 2.50, and 3.00 g/L) of seaweed humic acid balanced nutrient solution on plant height, stem diameter, and various physiological indicators of wheat seedlings using pot culture. The results showed that seaweed humic acid balanced nutrient solution could promote the growth of wheat seedlings. With the increase of fertilizer concentration, the plant height, stem diameter, superoxide dismutase (SOD) activity, vitamin C content, proline content, soluble carbohydrate content and chlorophyll content in wheat showed a trend of first increasing at first and then decreasing. On the whole, the optimum concentration of seaweed humic acid balanced nutrient solution for wheat growth in this experiment was 2.00 g/L.

Key words: seaweed fertilizer, wheat(Triticum aestivum L.), growth, resistance, seedling stage
