【摘要】 为探明玉米秸秆还田对大麻生长发育及麻皮产量的影响,于2015~2016年通过大田试验,设3个秸秆还田量水平,2个施氮量水平,重点对大麻田杂草藜密度和干物质量、大麻株高、茎粗、干茎重、麻皮产量进行了研究。结果表明,秸秆还田可减少大麻苗期杂草藜的密度与干物质量,显著提高大麻株高、干茎重及麻皮产量。实际生产中,建议玉米秸秆半量还田(4500 kg/hm~2)配施纯氮(229.2 kg/hm~2),可获得较好效果。更多还原

【Abstract】 A field experiment which was set up 3 levels of straw application rate plus 2 levels of nitrogen fertilizer was conducted to study the effects of corn straw incorporation growth and bast yield of hemp from 2015 to 2016.The results showed that straw returning resulted in the decrease of dry matter accumulation and density of goosefoot and the increase of plant height,dry stem weight and bast yield of hemp.To achieve the best effect of growth and bast yield of hemp,Corn-residue application treatment of 4500 kg/hm~2 plus pure nitrogen fertilizer of 229.2 kg/hm~2 would be appropriate.更多还原
