水溶性肥料对设施罗汉菜生长及产量的影响

Effects of Water Soluble Fertilizers on Growth and Yield of Thlaspi arvense

嘉秀罗汉菜生育期较长,常规生产需肥量大,为探索设施栽培条件下节肥增产的肥料运筹,以尿素和清水作对照,研究了不同类型水溶性肥料作追肥对设施罗汉菜生长及产量的影响。试验结果表明,水溶性肥料作追肥效果明显优于尿素,以腐殖酸水溶肥最佳,平衡型水溶性肥料次之,既减少了化学N的投入,又能促进罗汉菜生长,有利于提高产量。

Thlaspi arvense cultivar Jiaxiu had very long growth period and required a lot of fertilizers for conventional production. In order to explore the fertilizer application methods of high-yield and less-fertilizer under facilities culture condition, this paper researched the effects of different water soluble fertilizers （ WSF） as top-dressing on growth and yield of T.arvense using water and urea treatment as control in this test. The results showed that WSF as top-dressing was superior to urea, and WSF containing humic-acid was best, while balanced WSF took the second place, which not only reduced the chemical nitrogen input, but also promoted the growth and increased yield of T. arvense.
