Effects of Different Matrix Ratio on Cucumber Seedling Growth

Studying effects of different matrix ratio on growth of cucumber hole dish seedlings，can provide reference for cucumber hole dish seedlings in Hotan area of Xinjiang.Hole dish seedling technique was applied，coconut chaff，commodity organic fertilizer and sand were mixed to form a composite substrate according to different volume proportions for cucumber seedling raising.Five treatments and one control were set.Control substrate ratio was coconut chaff∶commercial organic fertilizer =20∶1，and substrate ratios of five treatments were coconut chaff∶sand∶organic fertilizer=16∶1∶1，coconut chaff∶sand∶organic fertilizer=18∶1∶1，coconut chaff∶sand∶organic fertilizer=20∶1∶1，coconut chaff∶sand∶organic fertilizer=22∶1∶1，coconut chaff∶sand∶organic fertilizer=24∶1∶1，and each treatment was repeated three times.Results showed that comprehensive subordinate function value of cucumber seedlings was higher and better than that of the control（coconut chaff∶organic fertilizer=20∶1） when substrate ratio was coconut chaff∶sand∶organic fertilizer=22∶1∶1.Under conditions of this experiment，the ratio of coconut chaff∶sand∶organic fertilizer=22∶1∶1 was used as substrate of cucumber plug seedling growth in Hotan area，which was beneficial to cultivation of strong cucumber seedlings，and could be used as substrate ratio of cucumber plug seedling in solar greenhouse in Hotan area.
