- 摘要:
- 针对全封闭温室夏季高温的现状，以小青菜为试材，采用沟式栽培法营造适宜作物生长的温度条件，研究了不同光环境和不同的灌溉量处理对全封闭温室内盆栽小青菜的产量和水分生产率的影响。结果表明：不同光环境下R+D处理温度最高，空气相对湿度基本保持在25%～60%之间，光照强度变化趋势基本相同，呈抛物线变化；生长指标中R+1/2处理的株高最大，而CK叶片数最少；R+1/2处理的盆栽小青菜蒸腾速率最大，各处理的蒸腾日变化规律并没有满足单峰曲线；R+1/2处理的产量、耗水量及水分生产率均表现最高。不同灌溉量试验中，株高、叶片数、产量、耗水量和水分生产率均表现出相同的变化规律为2T＞3T＞1T。由此可见，封闭温室内沟式栽培中适宜的补光和灌溉量可以大大提高小青菜的产量和水分生产率。
- Abstract:
- According to high temperature in summer in closed greenhouse,taking Brassica chinensis var.chinensis as material,the ditch cultivation was used to creation suitable growth environment for crops,effect of different light environment and irrigation of growth and water productivity in closed greenhouse were studied.The results showed that in the experiment of light environment,the temperature of R+D was maximum,the humidity remained at the 25%～60%,the trend of illumination was similar like a parabola.At the end of experiment,the plant height of R+1/2 was the highest and the leaf number of CK was the smallest in all treatments.The day transpiration of R+1/2 was the biggest,the change of the diurnal transpiration of all treatments did not follow a single peak curve.The water consumption and water productivity of R+1/2 was maximum.In the experiment of different irrigation,the plant height,leaf number,yield,water consumption and water productivity showed as 2T＞3T＞1T.Therefore,supplementary illumination and irrigation in the ditch cultivation can improve the yield and water productivity greatly.
