【摘要】 以白菜为试材,研究了水葫芦渣有机肥在高量、中量、低量3个施用水平下的施用效果。结果表明,水葫芦渣有机肥对白菜的生长发育具有明显的促进作用,从株高的指标看,以施有机肥高量效果为佳;从最大功能叶面积指标看,以施有机肥高量效果为佳;从开展度指标看,以施有机肥中量效果为佳。从白菜产量上看,有机肥化肥配施低用量、有机肥高用量、中用量差异不显著,均比空白增产370%、364%、297%。从白菜对养分吸收的含量上看,全氮以施有机肥高用量最好;全钾以施有机肥低用量最好。将水葫芦渣有机肥与其它常见的有机肥比较,其肥效与其它有机肥相当。更多还原

【Abstract】 Under three fertilizing standards(high quantity,medium quantity and low quantity),fertilizing effects of organic fertilizer of water hyacinth residues on Chinese cabbage were studied.The results showed that organic fertilizer of water hyacinth residues had a significant role in promoting the growth of Chinese cabbage.The high quantity organic fertilizer of water hyacinth residues could increase the plant height and leaf area of Chinese cabbage obviously,as compared with the other treatment.The medium quantity organic fertilizer of water hyacinth residues could make fabric width of Chinese cabbage wider than any other treatment.The differences of yields of low quantity organic fertilizer of water hyacinth residues and chemical fertilizer,high quantity and medium quantity organic fertilizer of water hyacinth residues was not significant,but the yields of low quantity organic fertilizer of water hyacinth residues and chemical fertilizer,high quantity and medium quantity organic fertilizer of water hyacinth residues were higher than no fertilization at 370%,364% and 297%.The high quantity of organic fertilizer of water hyacinth residues could make total nitrogen content of Chinese cabbage higher than any other treatment,but low quantity of organic fertilizer of water hyacinth residues could make total potassium content of Chinese cabbage higher.Moreover,comparing water hyacinth residues with other organic fertilizer,their fertilizer effects were not significanty different.更多还原
