利用稳定性同位素~(15)N示踪研究氮肥(尿素)利用率表明:在丘陵红壤土中,氮肥增效剂(硝化抑制剂)CP能提高柑桔对尿素的利用率,有利于果树的生长发育,并有明显的增产效果;对柑桔果实的质量没有影响.果实中CP的残留量也远远低于国家对CP在食物中残留量的规定.
The results of nitrogen (urea) utilization by stable isotope ~ (15) N tracing showed that in the hilly red soil, CP, a nitrogen synergist (nitrification inhibitor), can improve the utilization of urea by citrus, Growth and development, and have obvious yield-increasing effect, and have no effect on the quality of citrus fruits. The residual amount of CP in fruits is also far lower than the national provisions on CP in food.
