| 摘 要： | 为降低莴苣生产中化肥用量，实现节本增效，本研究在当阳市蔬菜主产区开展了莴苣化肥减量增效试验。结果表明，施用40%宜施壮高塔黄腐酸硫基功能型复合肥（N∶P2O5∶K2O=25∶5∶10，黄腐酸含量≥10%）处理表现最优，在化肥减量47.7%的条件下可提高莴苣产量、可溶性蛋白含量和维生素C含量，降低含水量，增加纯收入。说明该肥料可在莴苣生产中推广应用。

| Abstract: | The The application level of chemical fertilizer in vegetable production has always been high, and it has become one of the main sources of agricultural non-point source pollution. In the main vegetable producing areas of Dangyang city, a plot experiment was carried out to reduce the amount of lettuce chemical fertilizer and increase its efficiency. By using soil testing and formula fertilization technology to reduce the amount of chemical fertilizer, at the level of nearly 50% reduction, there was no obvious difference between the yield of lettuce formula fertilizer provided by two manufacturers and that of conventional fertilization experiment, and the yield increased by more than 5% compared with that of conventional fertilization reduction of 33.3%. In order to screen out the best fertilizer application scheme suitable for lettuce planting in Dangyang, and achieve the goal of reducing fertilizer and increasing fertilizer efficiency, four main fertilizer application schemes for lettuce planting by local farmers were compared, and the effects of different fertilizer application schemes on the yield and quality of lettuce were discussed, so as to screen out the best fertilizer application scheme suitable for local areas, improve fertilizer utilization rate and provide theoretical basis for lettuce planting. Through the field fertilizer efficiency test, it was found that the experimental formula fertilizer of lettuce (NPK 25-5-10+10) was superior to other treatments, and it had great popularization value. |
