新疆鹰嘴豆不同种植密度对其生长发育产量和品质的影响

以阿瓦提1号为材料,研究新疆地区不同种植密度对鹰嘴豆植株性状、干物质积累量、产量与品质的影响。结果表明,随密度的增加,生育期提前,株高增高,叶面积指数上升,单株干物质积累量减少。单株荚数随着密度增大极显著减少。每荚粒数、粒重等与密度的关系不大。蛋白质含量、亚麻酸含量和廿碳烯酸含量都呈现增加的趋势。种植密度对鹰嘴豆维生素B1和油酸含量的影响不显著。在本试验条件下,以44.5万株/hm2处理的表现最佳,产量达5946.09 kg/hm2,品质较好。

Effect of planting density on growth characters, yield and quality of chickpea (Cicer arietinum L.)

Effect of chickpea(Cicer arietinum L.) density on the plant character,dry matter accumulation per plant,yield character and yield,the trait of changing trends of the leaf area per plant and leaf area index(LAI) were studied under the condition of super-high yield in this experiment.The result showed that with the increase of the chickpea planting density,the plant birthing period were advanced,the plant height were heightened,LAI were increased and dry matter accumulation per plant were decreased.The No.of effectual pods per plant reduced remarkably with the increase of density.The No.of granule per pod and granule weight were not very related to the plant density.The protein content,flax acid content and twenty carbon alkene acid content are increased with the increase of density.The comprehensive performance of 445 thousand plants per ha was the best,with the highest yield 5 946.09 kg/hm2,and with good quality.
