含腐植酸水溶肥料在生菜田间试验

通过含腐植酸水溶肥料单因素生菜田间试验,结果表明：常规施肥+生菜施用含腐植酸水溶肥料对其改善生物学性状如根系、叶柄粗、叶绿素含量、叶片数、平均株高、平均单颗重,促进生长发育,提高产量有一定作用。增产明显,经济效益明显增加。三组比较,处理1(施用含腐植酸水溶肥料)比处理2(喷清水)亩增产139.8kg,增产率11.2%,产量差异呈极显著水平；比处理3(不喷任何液体)亩增产282.6kg,增产率13.9%。

Field experiment of humic acid containing water-soluble fertilizer in lettuce

Through the single factor field experiment of lettuce containing humic acid water-soluble fertilizer, the results show that conventional fertilization + application of humic acid water-soluble fertilizer to lettuce can improve its biological properties, such as root, petiole diameter, chlorophyll content, leaf number, average plant height and average single seed weight, promote growth and development and increase yield. The output increased significantly and the economic benefits increased significantly. Compared with the three groups, the yield of treatment 1 (applying water-soluble fertilizer containing humic acid) was 139.8kg higher than that of treatment 2 (spraying water), with an increase rate of 11.2%, and the yield difference was very significant; it was 282.6kg higher than that of treatment 3 (spraying no liquid), with an increase rate of 13.9%.
