摘要
为探索水溶肥对作物生长及产量的影响,以辣椒为试验对象开展了盆栽试验。结果表明:与大量元素水溶肥处理相比,添加8%腐植酸钾+10% EDTA-Mg的大量元素水溶肥处理的辣椒株高和茎粗分别显著提高6.54%、10.06%;开花期和成熟期辣椒单株叶面积、叶绿素相对含量分别显著提高45.45%、44.44%和8.52%、16.88%;辣椒果实全氮、可溶性糖、可溶性蛋白含量分别显著提高16.25%、5.42%、15.57%;辣椒产量显著增加11.70%。因此,腐植酸钾与Mg配施对辣椒生长及品质影响显著。
A pot experiment was conducted to know the effect of the water-soluble fertilizer on crop growth and yield of pepper.The results showed that compared with macroelement water-soluble fertilizer treatment,the plant height and stem diameter of pepper supplemented with 8% potassium humate + 10% EDTA-Mg were significantly increased by 6.54% and 10.06%,respectively.Leaf area and SPAD value were significantly increased by 45.45%,44.44% and 8.52%,16.88%,respectively during flowering and maturity stages.The contents of total nitrogen,soluble sugar and soluble protein in pepper fruits were significantly increased by 16.25%,5.42% and 15.57%,respectively.The yield significantly increased by 11.70%.Therefore,combined application of potassium humate and Mg had significant effect on growth and quality of pepper.
