尿囊素有对土壤微生物激活作用和促进小麦增产的双重效应。尿囊素对土壤激活作用表现为：刺激细菌增殖，其中固氮菌增加４．５８～１４．２７倍，放线菌增殖达显著水平，同时能显著抑制霉菌生长；改善土壤供肥性能，碱解氢增长１１．１％，Ｃｕ、Ｚｎ等微量元素有效含量增加。尿囊素能促进小麦对磷、镁等营养元素的吸收，增加叶绿素含量，提高光合效能，促进小麦早发壮苗，干物质积累明显提高，有利于争多穗、大穗，每公顷增加成穗２４．０万，小麦增产８．０～１３．８％。
Allantoin has the dual effect on soil microbial activation and wheat yield increase. The effect of allantoin on soil activation was as follows: stimulating bacteria proliferation, of which the azotobacter increased 4.58-14.27 times, the proliferation of actinomycetes reached a significant level, at the same time, it could significantly inhibit the growth of mold; improve soil nutrient performance, Hydrogen increased 11.1%, Cu, Zn and other trace elements increased. Allantoin can promote the uptake of phosphorus, magnesium and other nutrients in wheat, increase chlorophyll content, increase photosynthetic efficiency and promote early seedling growth and dry matter accumulation in wheat. 240,000 spike, wheat yield 8.0 ~ 13.8%.
