| 摘 要： | 本研究旨在探讨不同肥密因素对酿造高粱龙杂5号产量与品质的影响,采用二因素裂区设计,主处理施肥量因子5个水平,副处理密度因子4个水平。结果表明不同种植密度和施肥量对酿造高粱产量及品质影响显著。随密度增加,叶片净光合速率、叶绿素含量、单株干物质积累量下降,叶面积指数提高,产量增加,子粒淀粉含量下降,子粒单宁含量上升。随施肥量增加,净光合速率、叶绿素含量、叶面积指数、单株干物质积累量、子粒淀粉含量均下降,子粒脂肪含量上升。在施肥量375kg/hm 2条件下,随钾肥比例的增加,单株干物质积累量、叶面积指数及产量均增加。本研究认为15.4万株/hm 2的种植密度、375kg/hm 2（N∶P∶K=1∶0.7∶1.6）的施肥量是高产优质的合理组合。

| Abstract: | This experiment was designed to investigate the effects of different fertilizer and density on the yield and quality of sorghum Longza 5. The results showed that different planting density and fertilizer application had significant effects on yield and quality of brewing sorghum. With the increase of density, Pn, SPAD and amount of dry matter accumulated of one sample, LAI, yield increased, starch content decreased and tannin content decreased. With the increase of fertilizer application rate, Pn, SPAD, LAI, amount of dry matter accumulated of one sample and starch content decreased, and fat content increased. Under the condition of fertilizer in 375kg/hm 2, amount of dry matter accumulated of one sample, LAI and yield increased by the increase of the ratio of potassium fertilizer. In this experiment, The amount of fertilizer 375kg/hm 2（N∶P∶K =1∶0.7∶1.6）was used to be a reasonable combination of high yield and good quality, which density was based on 154 000 plants/hm 2. |
