| Abstract: | A field experiment was carried out to study on the effects of irrigation frequency on radish growth under drip irrigation in north China plain. The effects of irrigation frequency on LAI, chlorophyll content, body expanding, dry matter accumulation, root length density, root dry weight density in radish ware analyzed and discussed in this paper. Provided rainfall will supplied a significant portion of crop water requirements during radish growing season, it can be found that: ① there is no significant differences about radish growth among different irrigation frequency treatments, whether once every day or once every eight days; ② average weight per radish and yield per unit of land under drip irrigation are higher than those under furrow irrigation. |
