为探索等离子体处理大豆对化肥利用率的影响、最佳方法和增产机理,进行了等离子体处理大豆对化肥利用率的试验。试验采用5种剂量、7个处理三次重复随机排列。苗期调查处理根数比CK_1多1.8～2.9条。处理间株高变化不明显。结荚期、成熟期干物质的化验分析和测产,结果表明处理1.0A×2和1.5A×2的剂量能促进大豆吸收养分,(N+P_2O_5+K_2O)总量比CK_1提高10%以上;比CK_1提高化肥利用率,提高氮、磷、钾肥利用率为25.2%～32.9%、3.0%～6.7%和7.5%～13.5%。明确处理1.0A×2的剂量,比CK_1增产11.0%,效果显著。
In order to explore the impact of plasma treatment of soybean on fertilizer utilization, the best method and yield mechanism, the plasma treatment of soybean fertilizer on the utilization rate of the experiment. Five doses were used for the experiment, and seven treatments were repeated randomly for three times. The number of seedling investigation and treatment more than CK_1 1.8 to 2.9. No significant changes in plant height between treatments. The results showed that the treatments of 1.0A × 2 and 1.5A × 2 could promote the uptake of soybean and increase the total amount of (N + P_2O_5 + K_2O) by more than 10% compared with that of CK_1 ; Compared with CK_1, the utilization rate of chemical fertilizer was increased and the utilization rates of nitrogen, phosphorus and potassium were increased from 25.2% to 32.9%, from 3.0% to 6.7% and from 7.5% to 13.5%. The dose of 1.0A × 2 was clearly treated, which was 11.0% higher than that of CK_1, and the effect was significant.
