不同栽培基质对紫堇生长的影响

Effects of Different Culture Substrates on Growth of Corydalis edulis

为筛选出最适合和最经济的栽培基质,研究不同栽培基质对盆栽紫堇成活率、栽培性状以及生物量的影响。结果表明:紫堇在所有土壤基质处理中存活率差异不显著,但在不同基质中的生长情况存在明显差异。不同基质对于植株根系生长并无显著影响,但是对于地上部分养分的积累有显著影响。紫堇适应性强,对土壤要求不严,增加有机肥的园土是最佳栽培基质。

In order to screen out the most suitable and economical culture substrate, effects of different culture substrates on the survival rate, cultivated characters and biomass of Corydalis edulis in pot were compared. The results showed that there was no significant difference in the survival rate of Corydalis edulis in all culture substrates, but there were obvious differences in the growth of Corydalis edulis in different culture substrates. Different culture substrates had no significant effect on root growth, but had a significant effect on the accumu-lation of nutrients in the aboveground part of plants. Corydalis edulis had strong adaptability in Shanghai,and it was not strict with soil. The soil with increasing organic fertilizer is the best culture substrate for Corydalis edulis.
