The aims were to study the effects of“Lurong”on the yield of wheat, determine the optimal spraying period, and provide reference for wheat production. Wheat variety,‘Jinmai 84’was sprayed with a new compound foliar fertilizer“Lurong”at different stages after standing, then the characters of grain filling and yield components were analyzed. The results showed“base fertilizer heading spraying grain filling spraying ”and“base fertilizerjointing spraying heading sprayinggrain filling spraying”could prolong grain filling, and increase grain number per spike, spike number per plant and thousand kernel weight, further increased wheat yield. Specially, the result of spraying the foliar fertilizer at jointing, heading and grain filling stage individually had the best effect. It was suggested that the foliar fertilizer“Lurong”with 800 times dilution should be sprayed at jointing, heading and grain filling stage in wheat.
Key words
Wheat; Plant Compound Foliar Fertilizer; Grain Filling Character; Yield
