Abstract:
Some cultural practices of a new hybrid yuanhu were reported. The planting deusity of thc new variety wast using small seed tubers (2.8g/Per tuber ), 50~75 tubers/m2 for reprodu ction purpose, 100 tubers/m2 for high yield. 75 tubers/m2 was a suitable density when large or middle seed tubers was used. High reproduction coefficient and yield were obtained when the planting depth was 10cm. It was necessary to irrigate the hybrid yuanhu in North China.Adopting the negative pressure valuc of soil tumidometer as the guide of beginning to irrig ate and to obtain high reproduction cocfficient and to save water, 26.7kPa would be adopted as the initial point of irrigation, excecding 40.0 kPa led to a serious reduction of yield. The difference of yield between rubber tuber irrigaticn and drip irrigation treatment was not obvious, when planting with covering straw in level bed.
