摘要： 为探讨海河平原区不同种植方式对紫花苜蓿生产性状及饲用品质的影响。于2013-2016年开展了田间试验研究，在等播量条件下设置了10 cm行距条播、20 cm行距条播、30 cm行距条播、20-40 cm宽窄行条播以及撒播共5种种植方式处理，分析了株高、叶茎比、干草产量、倒伏级数、中性洗涤纤维含量、酸性洗涤纤维含量、粗蛋白含量、相对饲用价值等指标的变化规律。结果表明，不同种植方式下苜蓿的株高、叶茎比在相同年份、相同茬次下均无显著差异（P>0.05）；20-40 cm宽窄行条播下苜蓿第1茬干草产量显著低于30 cm行距条播（P<0.05），但苜蓿前2茬干草产量、累计3年干草产量与30 cm行距条播无显著差异（P>0.05）；不同种植方式下苜蓿的饲用品质指标无显著差异（P<0.05）；20-40cm宽窄行条播以及30 cm行距条播下的苜蓿倒伏相对较轻。综合得出，海河平原区采用撒播，10 cm至30 cm的等行距条播，以及20-40 cm宽窄行条播的种植方式均可，具体可根据实际情况而定。

Abstract: To eplore the effects of different planting methods on the production traits and forage quality for alfalfa in Haihe Plain. Field experiments were conducted in 2013 to 2016 by setting different row space,including 10 cm row space,20 cm row space,30 cm row space,20-40 cm wide and narrow row sowing and spreading under the same amount of seeding The variation of plant height,leaf-to-stem ratio,hay yield,loding drage,neutral detergent fiber (NDF),acid detergent fiber (ADF),crude protein and relative feed value,were analyzed. The results showed that there were no significant differences in plant height,leaf-to-stem ratio in the same year and same cutting under the different planting mehods (P>0.05). The hay yield of 1st cutting with 20-40 cm row space treatment was significant lower than 30 cm row space (P<0.05). However,the first two cutting hay yield,total hay yield of the 20-40 cm row space were significant higher than that of in 30 cm row space treatment (P>0.05). There were no significant differences in forage quality under the different planting pattern treatment (P>0.05). The lodging of the 20-40 cm row space and 30-30 cm row space treatment were relatively light. According to the comprehensive results,all the planting pattern with broadcast seeding, equal row sapcing of 10 cm to 30 cm,and wide and narrow row of 20-40 cm will be suitable for cultivation in haihe plain,which depend on the actual situation.
