摘要
以生菜为试材,采用田间试验方法,研究了大量元素水溶性肥料、微量元素水溶性肥料、含腐殖酸水溶性肥料等3种常见水溶性肥料对生菜农艺性状及产量的影响。结果表明:施用大量元素、微量元素和含腐殖酸水溶肥料均可改善生菜农艺和经济性状,具有显著的增产增收效果。以每667m^2计,喷施大量元素水溶肥比常规施肥(CK1)增产314.0kg,增产率23.5%,新增纯收入543.2元。比清水对照(CK2)增产249.0kg,增产率17.8%,新增纯收入493.2元。喷施微量元素水溶肥比常规施肥(CK1)增产251.0kg,增产率18.6%,新增纯收入417.8元。比清水对照(CK2)增产176.0kg,增产率12.4%,新增纯收入347.8元。施用含腐殖酸水溶肥比常规施肥(CK1)增产280.0kg,增产率20.5%,新增纯收入192.0元,比清水对照(CK2)增产236.0kg,增产率16.7%,新增纯收入184.0元。
A field experiment was carried out to study the effects of various water soluble fertilizer on agronomic traits and yield of lettuce.The results showed that macroelement water soluble fertilizer,microelement water soluble fertilizer and humic acid water soluble fertilizer could significantly improve the yield and economic value of lettuce.The yield increased by 23.5%,17.8%and output value increased by 543.2,493.2RMB/667m^2 compared with blank and water control in macroelement water soluble fertilizer;the yield increased by 18.6%,12.4% and output value increased by 417.8,347.8RMB/667m^2 compared with blank and water control in microelement water soluble fertilizer;the yield increased by20.5%,16.7%and output value increased by 192.0,184.0RMB/667m^2 compared with blank and water control in humic acid water soluble fertilizer.
