Abstract
A two years' pot experiment of planting sugarcane YZ00-236,designed to have five treatments varying in two different N application methods(drip N fertigation and traditional application N),was carried out to evaluate the effects of these treatments on the growth,yield and quality of sugarcane.The growth status of sugarcane at variable stages were measured,when the experiment were finishing,the cane yield and quality were measured too.The results obtained were as follows: compared with traditional way,drip N fertigation could significantly increase the cane yield,the increased data as 19.5%~41.5% in 2007 and 20.6%~36.8% in 2008,respectively.At the same time,the root length and root surface area would be increased significantly under drip fertigation,the increased data as 41.0%~53.2% and 41.7%~90.2%.When half dose of nitrogen application rate of conventional method through fertigation received the highest cane yield and improved the quality of sugarcane,then there have no increase or improving even reduce the cane yield and quality of sugarcane for excessive N use.Therefore,drip fertigation has some special advantages in sugarcane cultural since it provides the most effective way of supplying nutrients and water to the plant roots,and attention should be paid to the nitrogen application rate.
