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。
Taking lettuce as test material, three kinds of common water-soluble fertilizers such as water-soluble fertilizer, trace element water-soluble fertilizer and humic acid-soluble fertilizer were used to study the effect of yield and agronomic characters of lettuce. The results showed that the application of a large number of elements, trace elements and water-soluble humic acid-soluble fertilizer can improve lettuce agronomic and economic traits, with a significant yield increase effect. For every 667m ~ 2, spraying a large number of elements of water-soluble fertilizer than conventional fertilization (CK1) yield 314.0kg, yield 23.5%, net income of 543.2 yuan. Than the CK (CK2) yield 249.0kg, increase yield 17.8%, the new net income of 493.2 yuan. Spraying of trace element water-soluble fertilizer increased 251.0kg than conventional fertilization (CK1), yield increasing rate was 18.6%, new net income was 417.8 yuan. Than the CK (CK2) increase 176.0kg, increase yield 12.4%, the new net income of 347.8 yuan. The application of humic acid-containing water-soluble fertilizer increased the yield by 280.0 kg and the yield by 20.5% and increased the net income by 192.0 yuan and 236.0 kg respectively compared with that of CK2, with a yield increase rate of 16.7% and a net income of 184.0 yuan .
