摘要
通过两年的研究表明:小麦起垄栽培具有恒定地温、保持土壤水分、提高肥料利用率、促进根系下扎、边行优势明显的生态效应,有利于小麦分蘖成穗、增加穗粒数和千粒重,提高产量,较平播增产9.3～12.3%.
The two-year research indicates thet. bed-planting of wheat has Ecological effect on holding the ground temperature ,keeping the soil humidity ,raising the utilized coefficient of fertilizer ,promoting the root to plug the ground easily and edge effict being obvious. It can increase the number of spikes on tiller and grain on spike,raising a thousandgrain weight. Its yield inreases by 9.3～12.3% more than flat-planting.
