微生物有机肥与普通有机肥对“染井吉野”樱生长影响的比较研究
The Effect of Microbial Organic Fertilizer and Common Organic Fertilizer on Growth of Cerasus yedoensis

针对樱花培育过程中施肥过量现状，通过在主栽品种“染井吉野”樱中开展新型微生物有机肥替代普通有机肥，利用总氮量为减量指标在“染井吉野”樱容器苗及地栽苗中开展实验，实验以调查取得的常规施肥量为对照，根据不同林龄苗生长指标测定，衡量不同新型微生物肥减量处理对樱花培育过程的影响。结果表明，在容器苗中，总氮减量20%对于苗木的生长无影响；在地栽苗中，微生物有机肥处理前2a总氮减量20%对于幼苗生长无影响，地径超5 cm之后则需要增加肥料的施用量，保证苗木正常生长。
In view of the current situation of excessive fertilization during Cerasus yedoensis cultivation, the experiment was carried out in the container seedlings and seedlings planted in the field of Cerasus yedoensis by applying microbial organic fertilizer instead of common organic fertilizer to determine the characteristics of fertilizer requirements for seedlings of different ages. Total nitrogen amount was used as the fertilizer reduction index. The results showed that in container seedlings, the amount of fertilizer decreasing by 20% had no influence on the growth of seedlings. In ground planting seedlings, the reduction of 20% in the 2 years after treatment had no difference on growth. After the ground diameter to 5 cm, the application of fertilizer should be increased to ensure the growth needing of seedlings.
