The Compared Study Of The Cultivation Patterns Of Organic, Integrated And Conventional Vegetable Crops

In this study , we have continuously planted cucumber-tomato-celery and compared the three different planting patterns of vegetable crops, organic, integrated and conventional, in soil nutrients, growth, quality, yield, plant diseases and insect pests, economic benefit. By the comparison we want to put forth technical base for conventional vegetable producing.(1) The organic matter total N, total P, available K in organic pattern were higher compared to conventional pattern by 48.5%, 25.4%, -14.3%, 130.1% in the soil of 0~20cm; those in integrated pattern were higher than conventional by 5.1%, 4.3%, -29.4%, 81.6% in the soil of 0~20cm. And in organic pattern are higher than conventional by 35.2%, 5.7%, -2.9%, 94.9%in the soil of 20~40cm; integrated higher than conventional by 6.6%, -10.4%, -14.7%, 67.4%(2) Individual plant in organic and integrated patterns were respectively higher 34.2% and 22.9%; fruit weight of cucumber were higher 8.8% and 7.6% than conventional. Plant height, single fruit weight and yield in organic pattern were over 3.3%, 14.5%, 15.6 than integrated, 1%, 11%, 0.2% than conventional. Specific output of nitrogenous fertilizer of organic and integrated were more 6.2% and 6.3% than conventional; plant height of celery in organic and integrated patterns were respectively over 20.5% and 10.3%, output of each kilogram nitrogenous in organic and integrated patterns were higher 13.7% and 25.2%.(3 ) V c, total saccharide, dissoluble solid of tomato in organic produce were respectively more 11.9%, 14.1%, 3.9%than conventional; and those of celery in organic produce were morel 1.2%, 12.5%,43.8% than conventional.. The nitrate content of celery in organic, integrated and conventional patterns were 739.24mg/kg, 789.44mg/kg, 1065.73mg/kg.(4 ) The income of organic cucumber was lower 80.4% than conventional, that of integrated higher 96.0% than conventional; the income of integrated tomato was lower 44.1% than conventional; 16.4% organic over than conventional; that of organic and integrated celery were respectively 5.5% and -12.4% over than conventional.
