玉米秸秆堆肥处理效果研究及在生菜上的应用

Study on corn stalk composting effect and its application to lettuce production

通过试验比较不同制剂处理的玉米秸秆堆肥效果,同时研究了堆肥成品与商品有机肥对生菜生长的影响。结果表明:添加尿素或微生物菌剂对玉米秸秆堆肥时间、堆体体积变化影响不明显,各处理堆肥效果无显著差异;与商品有机肥比较,堆肥成品养分含量相当,且对生菜生长的影响较显著,单株重等指标优势明显,其中添加谷霖腐的玉米秸秆堆肥效果最佳。

Experiments of composting corn stalks were conducted through adding microorganism preparations and effects of both corn stalk compost and commercial organic fertilizer on lettuce growth were also investigated.The results showed that adding microorganism preparations or carbamide had not an obvious effect on the composting time and the compost volume.Compared with the commercial organic fertilizer,the compost was about the same in nutrient contents but significantly increased lettuce plant weight,and the compost added with the Gu Lin-fu preparation had the best effect.
