实验研究不同浓度的发酵水葫芦汁浸种大白菜,对其种子发芽的影响。实验结果表明,5%沼液的发芽势、发芽率均最高,100%沼液明显抑制种子发芽;通过单因素方差分析得到:根长、茎长、茎粗、叶长、叶宽、单株苗重的组间均存在显著性差异(P<0.05),即沼液浸种对大白菜各项生长指标有明显影响;并通过多重比较得知不同沼液浓度对大白菜芽的各项生长指标影响不同,其中5%沼液对单株苗重影响最大,较CK增重88.9%。综合各项指标,实验优选出5%沼液为大白菜发芽的最佳浸种浓度。
Experimental study of different concentrations of fermented water hyacinth juice soaking Chinese cabbage, the germination of its seeds. The results showed that the germination rate and germination rate of 5% biogas slurry were the highest, 100% biogas slurry significantly inhibited seed germination. The root length, stem length, stem diameter, leaf length, leaf width, single plant (P <0.05), that is, biogas slurry soaking significantly affected the growth indexes of Chinese cabbage; and through multiple comparisons, it was found that different biogas slurry concentrations had different effects on the growth indexes of Chinese cabbage buds Different effects, of which 5% of biogas slurry on the plantlet weight the greatest impact, weight gain than CK 88.9%. Combined with various indicators, 5% biogas slurry was the best soaking concentration for Chinese cabbage germination.
