通过潮土区田间试验,采用分设正交区组三因素五水平通用旋转组合设计研究了Mn与N、K配施对冬小麦产量的影响。结果表明,Mn与N、K合理配比可以显著提高小麦的产量。同时,N、K2 O和MnSO4 ·H2 O施用量分别为:2 2 8.2 6～313.6 4kg/hm2 ,12 3.85～2 0 6 .75kg/hm2 和35 .5 9～6 9.4 3kg/hm2 时,小麦产量可达到6 75 0kg/hm2 以上。从而为小麦高产条件下施肥提供了可靠的模型,可为农业生产起到了良好的指导作用。
The effects of Mn, N and K fertilization on the yield of winter wheat were studied by using the three-factor and five-level general rotation combination design in the orthogonal plot. The results showed that the reasonable ratio of Mn to N and K could significantly increase the yield of wheat. At the same time, the application rates of N, K2 O and MnSO4 · H2 O were 22.86 ~ 313.6 4 kg / hm2, 12 3.85 ~ 20.675 kg / hm2 and 35.59 ~ 6 9.43 kg / hm2, Output can reach more than 6 75 0kg / hm2. Thus providing a reliable model for wheat fertilization under high yield conditions, which can play a good guiding role for agricultural production.
