摘要:

文章分析比较了田间试验第2年,有机、SEQ、特别与常规栽培对8种蔬菜产量、品质的影响。结果表明,不同栽培方式8种蔬菜的产量趋势基本一致,即常规最高,有机最低,特别与SEQ居中。与常规栽培相比,有机栽培蔬菜减产幅度达到11.1%~64.4%。有机与常规栽培萝h、西兰花、番茄的产量差异达到1%水平显著,其他5种蔬菜的产量差异未达到5%水平显著。有机栽培番茄、芹菜的品质显著优于常规栽培的,Vc、干物质、可溶性糖含量较高,硝酸盐含量较低。但是有机与常规栽培西兰花、黄瓜、毛豆的品质差异不大。SEQ、特别栽培蔬菜的品质介于有机与常规栽培之间。

Abstract: A field experiment was carried on to study the effects of organic,SEQ,special and conventional farming on the yield and quality of eight kinds of vegetables in the second year. The changes in the yield of eight kinds of vegetables showed basically identical tendency. Compared with the conventional farming system,the yield of organic farming system decreased 11.1% to 64.4%. There was extremely significant difference between the yield of organic and conventional radish, broccoli and tomato, but no significant difference was found in other five kinds of vegetables. Organic tomato and celery were of better quality than conventional ones, containing more vitamin C, dry matter and soluble sugar,less nitrate. There was no significant difference between the quality of organic and conventional broccoli,cucumber and vegetable soybean. The quality of SEQ and special farming vegetables ranged between organic and conventional ones.
