两年研究结果表明:把适量的脲酶抑制剂混入当造甘蔗所用尿素内作基肥或于齐苗前全量一次施下的技术,比同量尿素按常规分次施用的技术(不混脲酶抑制剂),平均亩增产原料蔗493kg(n=102),增产率7.5%,达到统计显著标准。试验还表明:拌入脲酶抑制剂能提高甘蔗对尿素氮的吸收利用率9.1%,从而可节省尿素亩施用量约20%;减少尿素分次追肥2至3人工。穴植试验调查和统计结果还表明:此项技术,从甘蔗拔节开始,即能均匀促进蔗茎粗、节间长、株高的作用。脲酶抑制剂的适宜拌入量为尿素量的2%(旱地)至3%(水田)。施用期宜早,一般作基肥或在甘蔗苗期施用,但要确保深施和厚覆土。
Two years of research results show that: the appropriate amount of urease inhibitor mixed with sugar used in the manufacture of sugarcane as a base fertilizer or Qi Miao before the full amount of the same time than the same amount of urea routinely divided application of technology (not mixed urease inhibitor ), The average yield of raw sugarcane 493kg (n = 102), yield 7.5%, reaching a statistically significant standard. The experiment also showed that adding urease inhibitor could improve the absorption and utilization rate of urea nitrogen by 9.1%, which could save about 20% of the urea application and reduce the manure of 2-3 times. Hole planting test survey and statistical results also show that: This technology, starting from the sugarcane jointing, that is, can promote cane stem coarse, internode length, plant height. The appropriate amount of urease inhibitor to be added is 2% (dry land) to 3% (paddy field) of urea. The application period should be early, generally as a base fertilizer or sugar cane seedling application, but to ensure that deep and thick soil cover.
