不同用量腐殖酸在黄瓜减量增效施肥中的效果研究

Study on Effect of Different Humic Acids Amounts on Fertilizer Reduction and Efficiency Increase in Cucumber

研究了不同用量腐殖酸对温室黄瓜生长、土壤肥力和产量的影响,以期为减量增效施用腐殖酸提供实践基础。结果表明,与不施肥对照相比,腐殖酸各处理中黄瓜叶片中叶绿素和氮含量、土壤有机质和速效氮均较高,腐殖酸各处理可使黄瓜提早上市7 d左右,相同施肥量,Enersol原液各处理高于Enersol 299各处理。Enersol 299 22.50、45.00、67.50 L/hm2处理总产量较不施肥对照分别提高了6.02%、6.71%和10.88%,Enersol原液22.50、45.00、67.50 L/hm2处理分别提高了12.27%、14.12%和13.43%。其中以Enersol原液45.00 L/hm2处理减少了无机肥用量,提高了土壤肥力,增产效果显著。

To provide practice foundation on fertilizer reduction and efficiency increase,the effect of different amount humie acids on cucumber growth,soil fertility and yield were studied .The results showed that the leaf chlorophyll and nitrogen, soil organic matter and available nitrogen in humie acids treatment were higher than non-fertilization control ;Enersol stoste treatments were higher than Enersol 299 treatment with same fertilization level.Cucumber in humic acids treatment can sale 8 days earlier than non-fertilization control.Compared with non-fertilization control,the yield of Enersol 299 22.50,45.00,67.50 L/hm^2 treatment increased by 6.02% ,6.71% and 10.88% respectively,Enersol stoste 22.50,45.00,67.50 L/hm^2 treatment increased by 12.27%, 14.12% and 13.43% respectively.It can be included that Enersol stoste 45.00 L/hm^2 decreased the inorganic fertilizer, improved the soil fertility and distinct promoted the cucumber output.
