Research and Application of Fertigation Technique in Citrus Production in Hilly Region of Upstream of Lijiang River
Fertigation is a high efficient technology for agricultural production and has high application around the world.Lijiang Riv-er is famous for its beautiful scene,but now faces more challenges for the degraded ecology,especially water pollution.Citrus pro-duction is an important income source for farmers in agricultural production in Guilin,but traditional production methods,including excessive fertilizer and water use,may lead to waste of water and fertilizer and induce water pollution.According to this situation, the technique of fertigation is introduced into citrus production in hilly region of upstream of Lijiang River.Meanwhile,some parts of the fertigation system were improved.During one year experiment in 2014,the results showed that the technique could be more prac-tical and workable by the use of the improved fertigation system,which could reduce the input of citrus production and fertilizer ap-plication up to 45.6%,enhance citrus yield by 10.2% and net income by ¥35 680 per hm2.
