【摘要】：为了研究油菜秸秆与蓝藻无害化处理及资源化利用技术,开展了油菜秸秆与蓝藻混合及堆肥盆栽玉米的实验。设置了4组不同比例的油菜秸秆与蓝藻混合高温好氧堆肥处理,根据堆肥腐熟水平和肥效,筛选出油菜秸秆:蓝藻为3:2的处理,将其堆肥盆栽玉米,与施复合肥和不施肥处理比较分析玉米生长及品质指标。结果表明,油菜秸秆和蓝藻按不同比例混合堆肥过程中p H均维持在7~9,符合好氧堆肥对p H的要求,35 d后堆肥GI(germination index)在80%以上,达到完全腐熟标准。油菜秸秆与蓝藻按照3:2混合堆肥腐熟后,C/N从22.9降低为18.4,肥效(N+P2O5+K2O)为6.73%,优于其他各组。盆栽实验结果表明施堆肥和复合肥处理在玉米大喇叭口期株高与叶面积显著高于不施肥处理(P0.05),在玉米收获后株高、穗粗、穗粒数和百粒重、粗脂肪和粗蛋白含量均显著高于不施肥处理(P0.05),但堆肥处理与复合肥处理玉米生长、品质指标没有显著差异。油菜秸秆与蓝藻按照3:2比例混合好氧堆肥,35 d后完全腐熟,在肥效与安全性方面可以替代普通复合肥。
[Abstract]:In order to study the harmless treatment and resource utilization of rape straw and cyanobacteria, the experiment of mixing rape straw and cyanobacteria and composting potted corn was carried out. Four groups of rapeseed straw and cyanobacteria mixed high temperature aerobic composting were set up. According to composting maturity level and fertilizer efficiency, rape straw: cyanobacteria was treated at 3:2 and potted corn was compost. The growth and quality indexes of maize were compared with that of compound fertilizer and no fertilizer application. The results showed that the pH of rape straw and cyanobacteria mixed composting was kept at 7g / 9 in different proportion, and the compost GI(germination index was above 80% after 35 days of aerobic composting, which reached the standard of complete composting. The C / N of rape straw and cyanobacteria compost was decreased from 22.9 to 18.4, and the fertilizer efficiency of N P2O5 K _ 2O was 6.73, which was superior to the other groups. The pot experiment showed that the plant height and leaf area of compost and compound fertilizer treatments were significantly higher than that of non-fertilized treatment (P0.05N), and the plant height, ear diameter, grain number per ear and 100-grain weight were significantly higher than those of non-fertilized treatment at the stage of big bell mouth. The contents of crude fat and crude protein were significantly higher than that of non-fertilized treatments, but there was no significant difference in quality indexes between compost and compound fertilizer treatments. Rape straw and cyanobacteria were mixed with aerobic compost at 3:2 for 35 days, which could replace common compound fertilizer in fertilizer efficiency and safety.
