采用不同的肥料类型、滴灌定额、滴灌时间、滴灌频次对橡胶树小筒苗进行水肥滴灌，结果表明：(1)固体肥难稀释，滴灌不均匀易产生肥害；液体肥易稀释，不堵塞滴管，营养均衡，安全可靠。(2)筛选出2组橡胶树小筒苗水肥滴灌处理： A、液体肥适量频施，即每3 d 用45 mL 农家沼液肥控制在60 min 内滴灌于每株小筒苗； B、固体肥少量适施，即每6 d 用0．5 g 常规复合肥溶解稀释后控制在60 min 内滴灌于每株小筒苗。(3)综合苗木接穗部的增长量、根部表现及叶片养分状况来看，农家沼液肥有较佳的水肥滴灌效果。

The different type of fertilizer, irrigation quota, irrigation time, irrigation frequency were used in drip irrigation with fertilizer on rubber diminutive poly-tube budding. The result showed that: (1) Solid fertilizer was difficult to be diluted, the fertilizer damage symptoms would appear if the fertilizer wasn t uniformed in drip irrigation. Liquid fertilizer was easy to be dilu-ted, wouldn t block the dropper, contained balanced nutrition, and was safe and reliable. (2) Two groups of drip irrigation with fertilizer system were screened out for rubber diminutive poly-tube budding. The first one was using liquid fertilizer with high frequency of fertilization. Every 3 days 45 mL farm biogas slurry fertilizer would be used in drip irrigation in 60 minutes for each strain of diminutive poly-tube budding. The second one was using less solid fertilizer with suitable application frequency. Every 6 days 0. 5 g conventional compound fertilizer was dissolved and diluted and applied to each strain of diminutive poly-tube budding with drip irrigation in 60 minutes. (3) Applied farm biogas slurry fertilizer with drip irrigation had the best effect to the net growth of scion-portion, root performance and leaves nutrient content.
