摘要
针对夏季高温对日光温室叶菜生长的影响,分别对土壤+遮阳网、基质+遮阳网、基质+遮阳网+湿帘3种越夏种植模式进行对比试验,分析其对温室温湿度、叶菜生长及经济效益的影响。研究结果初步表明:一年中最热的一天,室外白天(早8:00~15:30)平均温度为32. 5℃时,土壤+遮阳网、基质+遮阳网种植模式室内白天平均温度分别比基质+遮阳网+湿帘种植模式温度高7. 1℃、6. 4℃。同时,室内白天平均相对湿度,基质+遮阳网比土壤+遮阳网种植模式低,基质+遮阳网+湿帘种植模式平均相对湿度最高。结合产量及效益可知,京研快菜、京水菜在基质+遮阳网+湿帘模式下产量最高,春油1号在基质+遮阳网模式下种植产量最高,3种叶菜在基质+遮阳网+湿帘种植方式下种植效益最好。
In view of effect of high temperature in summer on growth of leafy vegetables in solar greenhouse, a comparative ex- periment was conducted among three oversummer planting patterns： soil ＋ shading net, matrix ＋ shading net and matrix ＋ shad- ing net ＋ wet curtain. Effects on temperature and humidity of greenhouse, growth of leafy vegetables and economic benefits were analyzed. Preliminary results showed that on hottest day of year, average outdoor daytime （8 ： 00am -15 ： 30pro） temperature was 32.5 ℃. Average daytime temperature of soil ＋ shading net, matrix ＋ shading net planting mode was 7.1 and 6.4℃ higher than that of matrix ＋ shading net ＋ wet curtain planting mode, respectively. Meanwhile, average relative humidity of the indoor daytime was lower than that of the soil ＋ shade, and average relative humidity of the substrate ＋ wet curtain was the highest. According to yield and benefit, yield of Brassica pekinensis and Brassica japonica Sieb was the highest under mode of matrix ＋ sunshade ＋ wet curtain mode, the highest yield of rapeseed planted was under matrix ＋ sunshade mode. Three kinds of leaf vegetables were the best planting efficiency under substrate ＋ shade ＋ wet curtain planting.
