摘要
利用盆栽试验种植小白菜,比较研究施用浓缩沼液配方肥、腐植酸和氨基酸水溶肥及"奥捷"水溶性肥对蔬菜生长和土壤理化性质的影响。结果表明:与腐植酸、氨基酸水溶肥和"奥捷"水溶肥相比,施用浓缩沼液配方肥可显著提高小白菜产量及还原型Vc、可溶性糖等的含量,抑制硝酸盐积累,提高土壤过氧化氢酶、脲酶活性和土壤养分含量:浓缩沼液配方肥配施氧基酸叶面肥模式对小白菜生长和土壤理化件质的改善效果最显著。
Pot experiment was conducted to characterize the effects of concentrated slurry in formulated fertilizers on the growth of pakchoi and improvement of soil quality, comparing to concentrated slurry fertilizer, water formulated fertilizer and "Aojie" water-soluble fertilizer. Results showed that the biomass, ascorbic acid and soluble sugar of pakchoi were significantly improved by using formulated fertilizers made from concentrated slurry compared with formulated fertilizers made from water and water-soluble fertilizers from Aojie company. After fertilizing, the nitrate contents didn't accumulated, but the catalase, urease and the nutrients in soil were significantly improved. Simultaneously using the basal and foliar fertilizers made by concentrated slurry had the best performance on pakchoi growth and soil quality.
