- 摘要:
- 为更好地进行寒地玉米秸秆还田技术研究,以玉米为材料,在实验室条件下,以温度和细胞酶用量作为变量,以秸秆腐熟效率为腐蚀指标研究不同温度对寒地秸秆腐熟效率的影响。结果表明:随着温度的升高,秸秆的腐熟效率增加,细胞酶处理和对照之间的差异在减少。在接种细胞酶20 d后,10、15℃时,10 cm秸秆和5 cm秸秆的腐熟效果较好,与清水相比,差异达显著水平,20℃时各处理腐熟效果差异不显著。从试验结果还可看出,在同一温度下,10和5 cm秸秆腐熟剂的用量对秸秆腐熟效率影响不大;在接种细胞酶60 d后,各处理的秸秆基本腐熟完全,已经完全变软和变为褐色,不影响下茬作物耕作。由此得出:腐熟温度为10~20℃,细胞酶适宜用量为2~4 L?hm-2,腐熟天数为60 d最佳。秸秆还田可以提高土壤肥力,在腐解60 d后,对土壤中的有机质有所增加,达0.08%以上,氮磷钾等营养基本不变。
- Abstract:
- In order to deeply study maize straw counters-field technologyin frigid zones,the fermentation efficiency of mazie stover as affected by adding different amounts of cellular enzyme at a variety of temperatures was investigated.The results showed that the fermentation efficiency increased with the temperature increased; however,the effect of cellular enzyme was diminished at higher temperature.The maize stover became soft and turned into brown color 60 days after adding enzyme,indicating the fermentation process generally completed.At this stage,the final product would not affect the following cultivation.We recommend to use the final product for land application,which would benefit in increasing organic materials in soil while keeping relative stable levels of nitrogen (N),phosphor (P) and potassium (K).
