- 摘要:
- 以叶用油菜为试材，采用不同比例蚯蚓肥、竹炭、蛭石和腐殖酸等组分并添加竹醋液配制替代草炭的育苗基质，研究不同育苗基质的指标及其对叶用油菜苗期生长的影响。结果表明：以蛭石∶蚯蚓有机肥∶竹炭∶腐殖酸为6∶2∶1∶1并添加1 000 mL?m-3竹醋液的育苗基质，其有机质、水解氮含量最高，叶用油菜苗期叶长、叶宽及有效叶片数最大，可以作为替代草炭的新型育苗基质，有利于油菜苗期生长，提高育苗质量。
- Abstract:
- Pak choi was used as material,with different proportions of earthworm organic fertilizer,bamboo charcoal,vermiculite and humic acid fractions and added bamboo vinegar making substrates replace peat.The effects of above nursery substrates on the growth of pakchoi seedling were studied.The results showed that vermiculite∶earthworm organic fertilizer∶bamboo charcoal∶humic acid as a substrate of 6∶2∶1∶1 and added 1 000 mL?m-3 bamboo vinegar,the content of the organic matter and hydrolytic nitrogen were the highest,the leaf length,leaf width and the number of effective leaves were maximum at seedling stage.It could be used as a new seedling substrate instead of peat,conducive to pakchoi seedling growth and improve the quality of the seedlings.
