- 摘要:
- 为探明黑龙江西部地区粳稻最适宜施钾量,以垦稻12和龙粳21为材料,研究了不同钾肥施用量对垦稻12和龙粳21产量及产量构成因素的影响。结果表明,施肥量为171.0 kg·hm-2时,垦稻12和龙粳21穗数、穗粒数、结实率和产量最高,产量分别为9 540和9 770 kg·hm-2,与对照差异达显著水平。
- Abstract:
- For proving the optimum potassium fertilizer amount of japonica rice in the western of Heilongjiang province,taking Kendao12 and Longjing 21 as 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 171.0 kg·hm-2,the spike number,grain numbers per spike,seed rate,grain weight and yield were the highest,the yield of Kendao12 and Longjing 21 were 9 540 and 9 770 kg·hm-2 respectively,which had significant difference with control.
