水肥一体化技术在山地砂糖橘栽培上的应用

The Application of Integrated Water and Fertilizer Technology in the Cultivation of Sugar Orange in Hillside Area

传统的在山坡地上栽培砂糖橘,用肥量大,肥料的利用率较低,肥料流失严重。水肥一体化技术是目前节水控肥效果较好的一种农业技术。在山坡地上实施砂糖橘水肥一体化技术,是通过在山顶设计水池,水池下设置主管至山脚,在主管装置过滤网和减压阀,解决滴灌头堵塞及坡度管道水压压力差等问题,在主管两旁连接支管铺设滴灌管道到种植行,并在每株树边装上滴灌头。实践证明,水肥一体化技术能有效解决山地砂糖橘水、肥等问题,实现化肥减量增效。

The traditional cultivation of sugar orange in hillside land with the follow disadvantages:large amount of fertilizer,low utilization rate of fertilizer,serious fertilizer loss.The integrated water and fertiliz⁃er technology is a better agricultural technology for water saving and fertilizer control at present.The inte⁃grated water and fertilizer technology of sugar orange is implemented in the hillside land,by designing the pool at the top of the hill,setting the main pipeline under the pool to the foot of the hill,installing the fil⁃ter net and pressure reducing valve in the main pipeline,solving the issues such as the clogging of the drip irrigation head and the water pressure difference of the slope pipe,laying the drip irrigation pipe to the planting line by connecting the branch pipe on both sides of the main pipeline,and installing the drip irri⁃gation head on each tree edge.Practice has proved that the integrated water and fertilizer technology can ef⁃fectively solve the issues of water and fertilizer for sugar orange cultivation in hillside areas to reduce fertil⁃izer and increase efficiency.
