我国葡萄土壤有效磷丰缺指标和适宜施磷量研究
Study on Abundance-deficiency Index of Soil Available P and Appropriate P Application Rates for Grapes in China
摘要
Abstract
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/hm2,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/hm2 and 60 t/hm2 were 0-120,0-180,0-240,0-300,0-360,0-420 kg/hm2 and 0-480 kg/hm2,respectively;the APAR rangeed for phosphorus FUE of 35%,30%,25%,20%and 15%were 0-206,0-240,0-288,0-360 kg/hm2 and 0-480 kg/hm2,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/hm2 and 51-480 kg/hm2,respectively.关键词
