Abstract:In order to study the influence of urea and controlled-release urea combined with plant inducer on the wheat (Triticum aestivum L.) yields, nitrogen use efficiency and soil nutrients, a field experiment was designed with five treatments, which were controlled-release urea (CRU), controlled-release urea combined with plant inducer (CRUR), urea added plant inducer (UR), urea (U) and no nitrogen (CK) treatments as the control. The results showed:(1) Wheat yield of UR was significantly increased by 23.6%, the nitrogen use efficiency was improved by 10.1%, and the net income was significantly increased by 3 269 Yuan per hectare, compared with U. (2) Wheat yield of CRUR was significantly increased by 14.5%, the nitrogen use efficiency improved by 12.4% and net income was significantly increased by 2 361 Yuan per hectare, compared with UR. Wheat yield of CRUR was significantly increased by 16.3%, the nitrogen use efficiency was improved by 11.9% and net income was significantly increased by 2 446 Yuan per hectare, compared with CRU. (3) During the maximum nitrogen use efficiency period of wheat growth, soil nitrate content of CRUR was significantly increased by 29.5% compared with CRU, but increased by 88.2% compared with UR. Soil ammonium content of CRUR was significantly increased by 34.4% compared with UR. These findings indicated that CRUR could achieve synergistic effects, increase the wheat yield, nitrogen use efficiency, net income and soil available nutrient supply intensity. Then, the research results could provide reference for the development and application of slow and controlled-release fertilizer combined with plant inducers.
