研究了豫西褐土区旱地冬小麦施用钾肥的效果。结果表明,施钾量（K2O）在0～112.5 kg/hm2的范围内,随施钾量增加,小麦穗数、穗粒数和千粒重逐渐增加,各生育期总茎数及干物质积累量明显增加。施用钾肥对旱地冬小麦有显著的增产效果,增产幅度为7.9％～15.7％,最高产量（4 336kg/hm2）的施肥量（K2O）为114.2 kg/hm2,经济最佳产量（4 275.7 kg/hm2）的施肥量为77.4kg/hm2。
The effect of applying potassium fertilizer to winter wheat in the dryland of the cinnamon soil region of western Henan was studied. The results showed that with the increase of potassium application, the number of spikelets, grains per spike and grain weight per spike increased with the K2O applied in the range of 0-112.5 kg / hm2, and the total number of stems and dry matter accumulation in each growth stage were significantly increased increase. The yield of winter wheat increased by 7.9% ~ 15.7% and the maximum yield (4 336 kg / hm2) was 114.2 kg / hm2 and the economic yield was 4 275.7 kg / hm2 ) Of the amount of fertilizer is 77.4kg / hm2.
