摘  要:
For proving the optimum potassium fertilizer amount of japonicarice in the western of Heilongjiang province,taking Kendao12and Longjing 21as test materials,the effect of different potassium fertilizer amount on yield and component factors were studied.The results showed that when the potassium fertilizer amount was 171.0kg·hm-2,the spike number,grain numbers per spike,seed rate,grain weight and yield were the highest, the yield of Kendao12and Longjing 21were 9 540and 9 770kg·hm-2 respectively,which had significant difference with control.
