生物刺激素对韭菜产量、品质和植株养分的影响
Effects of Biostimulants on Yield,Quality and Plant Nutrients in Allium tuberosum
摘要
Abstract
To explore and obtain new fertilizers suitable for Allium tuberosum growing in facilities,the study take single-root red Chinese chives as test materials to research the influence of 5 types of biostimulant,namely chitin,amino acid,fish protein,alginic acid and humic acid on Allium tuberosum's output,quality,photosynthetic pigment content and plant nutrient in the condition with the same content of nitrogen fertilizers applied.The results showed that applying different types of biostimulant can significantly increase the total output and tillering number of Allium tuberosum,and the overall output and tillering number of the Allium tuberosum treated with humic acids increased by 24.40％and 24.41％respectively in comparison to those treated with common nitrogen fertilizers.The influences of different types of biostimulant on the contents of Allium tuberosum's soluble sugars,soluble proteins and VC are different,and the humic acids with the content of 30 kg·hm-2 show the best treatment effect.They not only improve the contents of the pyruvic acids in plants and chlorophyll a and chlorophyll b in leaves,but also significantly reduce the contents of nitrates and cellulose.The contents of total nitrogen,total phosphorus and total potassium in Allium tuberosum treated with humic acids are significantly higher than those treated with regular nitrogen fertilizers and blank control,showing the highest nitrogen partial factor productivity,agricultural efficiency and input-output ratio.The comprehensive analysis shows that the humic acids with the content of 30 kg·hm-2 can realize high-output and high-quality Allium tuberosum production.关键词
