为探明负压灌溉条件下小白菜生长发育的适宜负压和土壤含水量,采用土壤盆栽试验结合负压灌溉技术,研究2种土壤（潮菜园土、红菜园土）和3个供水负压（-5.0 k Pa、-10.0 k Pa、-15.0 k Pa）对小白菜生长发育及生理指标的影响。结果表明,小白菜生物产量和根系活力在2种供试土壤条件下均以-5.0 k Pa处理最高,随着供水负压值的降低,生物产量和根系活力显著下降;脯氨酸含量以-10.0 k Pa处理最高,显著高于-5.0k Pa和-15.0 k Pa处理;水分利用效率以-5.0 k Pa处理最低,显著低于-10.0 k Pa和-15.0 k Pa处理。综合小白菜生物产量、水分利用效率及对不同供水负压的生理响应,2种供试土壤适宜小白菜生长发育的...

In order to find out the suitable negative pressure and soil water content for the growth and development of Chinese cabbage under negative pressure irrigation,this paper conducted a pot experiment combining with negative pressure irrigation technology to study the effects of 3 negative pressure levels（-5.0 k Pa,-10.0 k Pa,-15.0 k Pa）on the growth and physiological index of Chinese cabbage in 2 types of vegetable soils（ alluvial garden soil and red-garden soil）. The results showed that the biomass and root system activity（ TTC reduction） ...
