摘　　要：2004年在吉林省桦甸市桦郊乡进行了等离子体种子4种不同剂量、6个处理区的试验。经过在拔节期、成熟期干物质的化验分析和测产,结果表明应用等离子体种子处理1.0A×2和1.5A×2的剂量能促进玉米吸收养分,(N+P2O5+K2O)总量比CK1提高10%以上;比CK1提高化肥利用率即提高氮肥、磷肥和钾肥利用率为7.4%～8.2%、11.3%～19.7%和15.7%～23.5%。明确了等离子体种子处理1.0A×2的剂量,比CK1增产8.2%,效果显著。Plasma treatments at the dosage of 0.5A×2-2A×2 on Maize seed were carried out in Huadian county Jilin province in 2004. Dry matters were sampled and chemical analyzed in shooting and maturity stage and yield estimation was taken before maturity. The result showed that plasma treatments at the dosage of 1.0A×2 and 1.5A×2 could increase nutrient uptake and fertilizer use efficiency on maize seed. The total fertilizer of N＋P2O5＋K2O was increased by above 10% compared to the control. The N and P and K use efficiency was enhanced by 7.4%-8.2%, 11.3%19.7% and 15.7%-23.5%, respectively. It was clarified that plasma treatments at the dosage of 1.0A×2 could increase yield significantly by 8.2%.
