摘　　要：为解决膜上打孔种植中存在的扣苗放苗、作物早衰、地膜回收难等问题,采用当地主栽谷子品种张杂谷16号和神谷99作为试验材料,针对自主研发的2MBFC-1/2多功能膜侧精量播种机使用过程中谷子膜侧栽培技术中的关键技术指标进行了两年试验。结果表明,在种植档位为5档(播种量为4.950 kg·hm^(-2))时,穗长、植株干重、千粒重和产量均最大。不同播种深度下,植株株高、谷穗穗粗均没有显著性差异。穗长、植株干重、千粒重和产量在播深为5 cm时均为最大。建议在农业生产中使用此播种机具播种谷子时,档位调为5档,种植深度调试为5 cm,植株性状和产量效果最佳。In order to solve the problems of seedling release,crop premature senescence,and difficulty in plastic film recovery in the process of planting with holes in plastic film,the local main millet varieties Zhangzagu 16 and Shengu 99 were used as test materials,and the key technical indicators of the film side cultivation technology of millet in the use of the independently developed 2MBFC-1/2 multi-function film side precision seeder were tested for two years.The results showed that the ear length,plant dry weight,1000 grain weight and yield were the largest when the planting gear was 5(4.950 kg·ha^(-1)).There was no significant difference in plant height and ear diameter between different treatments under different sowing depths.Ear length,plant dry weight,1000 grain weight and yield were the largest when the sowing depth was 5 cm.So,it is suggested that when this sowing technology is used in sowing millet,the best effect is achieved when the gear is adjusted to 5 and the planting depth is adjusted to 5 cm.
