不同纳米硒肥叶面喷施对西兰花产量、品质及硒含量的影响

Effects of Different Concentrations of Nano-SeleniumFertilizeron Yield,Quality and Selenium Content of Broccoli

以西兰花品种“耐寒优秀”为试验材料,研究了2种纳米硒肥叶面喷施对西兰花产量、品质及其活性成分和硒含量的影响。结果表明,适宜浓度的纳米硒肥可以显著提高西兰花的品质和产量,其中真希500倍液处理的产量、品质指标和硒含量等都显著高于喷施等量水的处理(CK),产量和硒含量分别高出CK 66.67%和343.0%,鱼肽·硒素1000倍液处理的西兰花产量和硒含量分别高出CK 55.6%和146.0%,可见适宜浓度的纳米硒肥叶面喷施对西兰花提高产量,改善品质有明显的促进作用。

Taking“Naihanyouxiu”of broccoli variety as experimental material,the effects of two kinds of nano-selenium fertilizer spraying on the yield,quality,active components and selenium content of broccoli werestudied.The results showed that suitable concentration of nano-selenium fertilizer can significantly improvethequality and yield of broccoli,among which the yield,quality index and selenium content of Zhenxi 500timessolution were significantly higher than spraying the same amount of water treatment(CK),and the yieldandselenium content were 66.7%and 343%higher than CK,respectively.The yield and seleniumcontent of broccoli treated with 1000 times of fish peptide and selenium were 55.6%and 146%higher than CK,respectively.It canbe seen that the suitable concentration of nano-selenium fertilizer spraying on the leaf surface can significantlypromote the yield and quality of broccoli.
