Effects of Water and Fertilizer Integration on Yield and Benefit of Citrus

[Objective] Aiming at the problems of low fertilizer utilization rate and large amount of labor by the traditional fertilization technique,the effects of yield and benefit on the citrus were studied by integration technology of water and fertilizer,which achieved the purpose of the saving fertilizer and work,and the increasing efficiency. [Method] As the test materials of the precocious Gongchuan mandarin,Liucheng tangerine and Satang tangerine in Liucheng County,Liuzhou City,Guangxi Province,the effects of yield and benefit of different treatments were counted up by the technology of the formula fertilizer combined with drip irrigation. [Result]By the technology of the formula fertilizer combined with drip irrigation,compared with the control,fertilizer use cost of treatment①,treatment② and treatment③ decreased by 55. 04%,39. 96% and 24. 98% respectively,labor costs decreased by 68. 89%,production has greatly increased. Among them,the best effect was treatment ②. [Conclusion]Using the traditional fertilization technique had the problems of low fertilizer utilization rate and large amount of labor,a better solution way was used by the technology of the formula fertilizer combined with drip irrigation.
