摘要
采用随机区组设计,研究了垄上单、双行种植方式及施肥量对饲用甜高粱杂交种天青一号产量和品质的影响。结果表明,不同种植方式间叶片含氮量差异不显著;垄上双行处理群体各层PAR值较小;同一施肥水平下,以垄上双行种植方式的鲜质量较高,同一种植方式下,以施肥水平高者鲜质量高,最高产量达58.28t/hm2;鲜质量与各品质指标相关系数较小,且各品质指标间差异均未达显著水平。
The randomized block design was used to study the effects of single or double row ridge and fertilizer quantity on the yield and quality of sweet sorghum hybrid Tianqing 1.The results showed that the difference of leaf nitrogen content was not significant between the two planting ways.For double row ridge treatment,the PAR value was relatively less in every colony layer.In same fertilization level,the fresh matter yield of double row ridge was higher.In same planting way,the fresh matter yield increased with the increase of fertilizer amount,the highest yield being 58.28t/ha.The correlation coefficient between fresh matter yield and quality indexes was low,and the difference between quality indexes was not significant.
