【摘要】 为海南成林油茶的可持续发展和高产栽培提供科学依据,采用"3414"设计,通过田间试验方法,研究优化海南成林油茶氮磷钾肥最佳配比与施用量。结果表明:海南油茶的产量受氮肥影响最大,其次是磷肥,钾肥影响较小;氮、磷、钾肥施用量分别为0.205kg/株、0.091kg/株和0.181kg/株时油茶最高产量为6.95kg/株。结合当地油茶生产实际,建议油茶生产上氮、磷、钾肥施用量分别为0.190～0.205kg/株、0.080～0.091kg/株和0.151～0.181kg/株,氮、磷、钾肥的适宜配比为1.00∶(0.40～0.50)∶(0.80～0.90)。更多还原

【Abstract】 The optimum ration of N,P and K fertilizer and its application level for Camellia oleifera forest in Hainan are optimized and studied by using 3414 design and conducting a field test to provide the scientific basis for sustainable development and high-yield cultivation of C.oleifera forest in Hainan.Result:The yield of Hainan C.oleiferais affected by N fertilizer most greatly,followed by P fertilizer,and K fertilizer has the least effect on the yield.When the application level of N,P and K fertilizer is0.205 kg/plant,0.091 kg/plant and 0.181 kg/plant respectively,the yield of C.oleifera reaches the highest(6.95 kg/plant).Combing with the actual situation of C.oleifera production in local area,it is recommended that the application level of N,P and K fertilizer is 0.190-0.205 kg/plant,0.080-0.091 kg/plant and 0.151-0.181 kg/plant in production of C.oleifera,and the suitable ration of N,P and K fertilizer is 1.00∶(0.40—0.50)∶(0.80—0.90).更多还原
