1.固氮菌肥料应用于肥沃的土壤如血马肝和直砂土,不论在田间的试验和盆栽的试验,均获得水稻作物产量的提高。2.固氮菌在血马肝和直砂土内的存活率比较多,在鸡屎土内则低,由于固氮菌的存在,大大加强了土壤和水稻根际细菌的活动性。3.鸡屎土不能显示菌肥的肥效,主要由于它的肥沃性差,缺乏足移的营养条件,土壤质地粘重,结构不好,处于强烈的还原情况,这对于微生物的活动有着不利的影响。4.细菌肥料的应用问题:(1)应施用当地的菌系菌剂,它们最适合于当地的生活环境。(2)制好的菌剂应立即施用,在包装良好的情况下,保存一个月,有益细菌已死去98.3%,在包装不良的情况下,情况更为恶劣。(3)菌肥必须施用于近根部,因为菌肥的扩散范围是不大的。(4)细菌肥料仅能作为一种辅助肥料,应跟上各项增产措施,即使在贫瘠的土壤上,亦能发挥有益的作用。
1. Azotobacter fertilizers applied to fertile soils such as blood and liver and straight sand soil, both in field trials and potted plants, have been increased rice crop yields. Azotobacter survival rate in the blood of horseshoe crabs and straight sandy soil more, in the chicken stool soil is low, due to the presence of nitrogen-fixing bacteria, soil and rice rhizobacteria greatly enhanced activity. Chicken feces soil can not show the effectiveness of fertilizer, mainly due to its poor fertility, lack of adequate nutrition conditions, soil texture sticky, poor structure, in a strong reduction, which has adverse effects on microbial activity . 4. Bacterial fertilizer application problems: (1) should be applied to the local bacterial strains of bacteria, they are most suitable for the local living environment. (2) Prepared good antibacterial agent should be immediately applied, in a well-packaged case, save a month, beneficial bacteria have died 98.3%, in the case of poor packaging, the situation is even worse. (3) Bacterial fertilizer must be applied to the near root, because the spreading range of bacterial fertilizer is not big. (4) Bacterial fertilizers can only serve as a kind of auxiliary fertilizer, and should follow up the stimulation measures and play a beneficial role even in barren soil.
