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

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.
