临麦2号高产高效优化栽培施肥技术研究

Study on the Optimum Application of Fertilizer for High-yielding and Benefit in Winter Wheat——Linmai 2

采用正交旋转组合设计研究了N、P2 O5、K2 O与小麦产量的关系。结果表明 ,增施氮磷肥是实现临麦 2号高产高效优化栽培的关键 ,增施磷肥更利于氮肥肥效的发挥。实现临麦 2号高产高效优化栽培的施肥措施是 :施纯N 14 0 .79～ 3 45 .5 6kg/hm2 ,P2 O5177.3 1～ 2 2 5 .0 0kg/hm2 ,K2 O 60 .78～ 14 5 .92kg/hm2 。

The study on the interrelationships among the 3 cultivation measurements(N-fertilizer,P-fertilizer,K-fertilizer) and yield of winter wheat variety--Linmai 2 was conducted by the application of the design of perpendicularity rotational combination and the result showed that more N-fertilizer and P-fertilizer were the key measurements for the optimum cultivation of winter wheat variety--Linmai 2.It also showed that more P-fertilizer applied made N-fertilizer more effective.The results showed that the optimum cultivation measurements for high-yielding and high economic benefit were the combination of N-fertilizer:140.79 to 345.56 kg/hm 2,P-fertilizer:177.31 to 225.00 kg/hm 2 and K-fertilizer 60.78 to 145.92 kg/hm 2.
