为有效提高尿素氮利用率,促进新型缓/控释氮肥的研发。在盆栽试验条件下,研究了脲酶抑制剂氢醌(HQ)部分或全部包膜与尿素掺混施用对小麦生长及土壤不同形态氮素含量和脲酶活性的影响。试验共设5个处理:对照(CK)、普通尿素(U)、U+普通HQ (SRU1)、U+包膜HQ (SRU2)和U+30%普通HQ+70%包膜HQ (SRU3)。结果表明:与SRU1相比,包膜HQ能够促进小麦生长,改善小麦产量构成,增加小麦产量,并提高氮素利用率,其中SRU2、SRU3分别增加了小麦产量的34.71%,56.54%;与SRU2相比,SRU3处理中普通HQ与包膜HQ配合施用前期能够有效抑制尿素水解,维持土壤中NH4+—N的适宜浓度,后期能增加土壤NH4+—N含量,保证土壤有效氮的持续供应,减少氮素损失,使小麦整个生育期内土壤脲酶活性维持在较低水平。综上,HQ部分包膜与尿素掺混施用的SRU3处理土壤氮的供应能力最强,氮素利用率最高,对小麦生长的促进作用最显著。
In order to improve the utilization rate of urea nitrogen and promote the research and development of new slow/controlled release nitrogen fertilizer
a pot experiment
which including five treatments as control (CK)
common urea (U)
U + common urease inhibitor HQ (SRU1)
U + coated HQ (SRU2)
and U + 30% common HQ+70% coated HQ (SRU3)
were conducted to study the effect of partially or completely coated HQ mixed with urea on wheat growth
soil nitrogen
and urease activity. The results showed that compared with SRU1
coated HQ can promote wheat growth
improve wheat yield components
increase wheat yield
and improve nitrogen utilization rate. SRU2 and SRU3 respectively increased the yield of wheat by 34.71% and 56.54%. Compared with SRU2
SRU3 treatment of common HQ mixed with Coated HQ could effectively inhibit the hydrolysis of urea at the early stage
maintain the appropriate concentration of NH4+-N in soil
and increase the content of NH4+-N at the later stage
so as to ensure the continuous supply of available nitrogen in the soil
reduce the loss of nitrogen
and maintain the urease activity of soil at a low level for a long time in the whole growth period of wheat. SRU3 treatment had the strongest nitrogen supply capacity and the highest nitrogen utilization rate in soil
and had the most significant effect on the growth of wheat.
