The resuIts showed that the appIication of special controI ed reIease fertiIizer for rapeseeds avoids earIy decIine of rapeseed resuIting from fertiIizer Ioss by one-off appIication, improves the number of green Ieaf before winter, and extends photosynthetic Iifespan of pods, which significantIy increases yields. What＆#39; more, with higher output-input ratio, the fertiIizer takes ad-vantages in saving cost, Iabor and increasing yield.展开更多

[Method] The research conducted a test in field to expIore the effects of N and P fertiIizers on malze yield. [Result] Both of N and P fertiIizers have significant effects on malze yield. When malze yield reached the highest, the quantities of N fertiIizers and P fertiIizers were 530.56 and 105.44 kg/hm2, respectiveIy. [Conclusion] Malze yield keeps growing upon N or P fertiIizers to certaln extent, and excessive quantities of N and P fertiIizer wouId reduce malze yield.展开更多
