有机、无公害与常规蔬菜生产模式土壤及植株性状比较研究初报

Comparison of soil and plant characteristics in organic, integrated and conventional cultivation patterns of vegetable production

  • 摘要: 试验研究结果表明,施用有机肥可促进蔬菜植株生长和增产,且有利于改善土壤理化性质,提高土壤肥力。有机、无公害生产模式土壤有机质、全N、速效钾含量分别较常规生产模式高48.5%、25.4%、130.1%和5.1%、4.3%、81.6%;有机生产模式西红柿维生素C、总糖、可溶性固形物分别比常规生产模式高11.9%、14.1%和3.9%,芹菜维生素C、总糖、可溶性固形物分别较常规生产模式高11.2%、12.5%和43.8%。有机、无公害生产模式芹菜NO-3含量分别较常规模式低30.6%和25.9%。

     

    Abstract: The comparative experiments indicate that the application of organic fertilizer can promote the plant growth, increase the vegetable yield and improve the physical and chemical characters and fertility of soil. By using the organic and integrated cultivation patterns, the contents of organic matter, total N, available K in the soil are 48.5%,25.4%,130.1% and 5.1%,4.3%,81.6% higher than those by using the conventional cultivation pattern. The study on tomato shows that the vitamin C, sugar and soluble solid contents of the plant in the organic pattern are 11.9%,14.1% and 3.9% higher than those in the conventional pattern. The study on celery shows that the vitamin C, sugar and soluble solid contents of the plant in the organic pattern are 11.2%,12.5% and 43.8% higher than those in the conventional pattern. The nitrate contents of the plants in the organic and integrated patterns are 30.6% and 25.9% lower than those in the conventional pattern.
