摘要
为建立我国葡萄测土推荐施磷系统,本研究采用作物土壤养分丰缺指标推荐施肥系统研究新方法,探讨了我国葡萄土壤有效磷丰缺指标与适宜施磷量。结果表明,我国葡萄土壤有效磷第1~7级丰缺指标依次为≥95、35~95、13~35、4.5~13、1.7~4.5、0.6~1.7 mg/kg和<0.6 mg/kg。在葡萄目标产量15~60 t/hm^(2)、磷肥利用率15%~35%、土壤有效磷丰缺级别第1~7级情形下,目标产量15、22.5、30、37.5、45、52.5、60 t/hm^(2)的适宜施磷量范围分别为0~120、0~180、0~240、0~300、0~360、0~420、0~480 kg/hm^(2);磷肥利用率35%、30%、25%、20%、15%的适宜施磷量范围依次为0~206、0~240、0~288、0~360、0~480 kg/hm^(2);有效磷丰缺级别第1~7级土壤适宜施磷量分别为0、9~80、17~160、26~240、34~320、43~400、51~480 kg/hm^(2)。
To establish the system of soil testing and P fertilizer recommendation for grapes in China,a new study method for crop recommended fertilization system based on soil nutrient abundance-deficiency index(ADI)were employed to investigate the ADI of soil available P(SAP)and the appropriate P application rates(APAR)for grapes in China.The results showed that the ADI of SAP for grapes in China for the 1st to 7th level were≥95,35-95,13-35,4.5-13,1.7-4.5,0.6-1.7 mg/kg and<0.6 mg/kg,respectively.When the target yield of grapes was 15-60 t/hm^(2),the fertilizer use efficiency(FUE)of P was 15%-35%,and the abundance-deficiency levels(ADL)of SAP was from 1st to 7th,the APAR ranges for target yields of 15,22.5,30,37.5,45,52.5 t/hm^(2) and 60 t/hm^(2) were 0-120,0-180,0-240,0-300,0-360,0-420 kg/hm^(2) and 0-480 kg/hm^(2),respectively;the APAR rangeed for phosphorus FUE of 35%,30%,25%,20% and 15% were 0-206,0-240,0-288,0-360 kg/hm^(2) and 0-480 kg/hm^(2),respectively;the APAR ranges for ADL of SAP from 1st to 7th were 0,9-80,17-160,26-240,34-320,43-400 kg/hm^(2) and 51-480 kg/hm^(2),respectively.
