不同灌水量对木薯需水量及产量的影响研究

Influence of different irrigation amount on water requirement and yield of Cassava

研究了不同灌水量下木薯的需水量以及产量的变化。试验结果表明,木薯的株高和径粗随着灌水量的增加而增大;木薯的需水量在9～10月达到最大值,这是由于受植株本身生物量和气候条件影响;木薯需水量在1 969.88～2 160.74 mm范围内产量表现最佳,但需水量过高或过低,都影响到产量的增加。

The test under different irrigation water changes of water requirement cassava and yield.The results show that cassava plant height and stem diameter,with the increase of irrigation amount;cassava water requirement demand in the September to October the maximum,the plant that itself due to weather conditions and the impact of biomass;cassava in water requirement 1 969.88~2 160.74 mm range,yield show the best performance,but high or low water demand have affected the growth of yield.
