以露地种植的习惯模式为对照,通过示范试验,对设施蔬菜6种不同种植模式的农时利用与经济效益进行了比较研究.结果表明:6种不同种植模式与对照相比,其蔬菜年商品产量、单位面积总收益、净收益均有大幅度提高,其商品产量与总收益是CK的2倍左右,净收益是CK的3.0～5.5倍.尽管6种设施种植模式的设施成本、物质成本及活化成本均比CK高,但是高投入实现了高产出、高收益,其设施成本收益达3.11～6.27,物质成本收益达2.14～3.19,活化成本收益达1.96～4.18,各项成本收益均处于较高水平,其边际成本报酬率也达1.54～3.56的良好水平.%Taking the traditional open air planting pattern as the control, this study compared the using of farming season and economic benefit of protected vegetables planted by six different patterns through the demonstrative tests. The results showed that these 6 different planting patterns had greatly higher annual yield of vegetable, total income per unit area and net income than the check, their commercial yield and total income were about 2 times of those of CK, and their net income was 3.0 ～ 5.5 times of that of CK. Though the cost of facility, material and activation in 6 different protected vegetable cropping patterns was higher than that in CK, higher input finally led to higher output and higher economic benefit, the cost - benefit of their facility, material and activation reached 3. 11 ～6.27, 2.14 ～3.19 and 1.96 ～4.18 respectively, being at higher level; their rate of return on the marginal cost was also at 1.54 ～3.56 level.
