我国葡萄土壤氮素丰缺指标和适宜施氮量初步研究
Preliminary study on abundance-deficiency index of soil nitrogen and appropriate N application rates for grapes in China
摘要
Abstract
To lay a theoretical basis for grapes soil testing and fertilizer recommendation in China,this study retrieved literature on grapes N fertilization in China,extracted the data of soil organic matter(SOM),total nitrogen,alkaline hydrolysis nitrogen(SAHN),as well as the yield for N deficiency and N application treatments.A new study method for recommended fertilization system of crop based on soil nutrient abundance and deficiency index(ADI)were employed to investigate the ADI of soil nitrogen and the appropriate N application rates(ANAR)for grapes in China.The results showed that:The ADI of SOM for the 1st to 8th level were ≥75,36-75,17-36,8-17,4-8,2-4,1-2 and＜1 g/kg,respectively;The ADI of SAHN for grapes in China for the 1st to 8th level were ≥288,158-288,87-158,48-87,26-48,15-26,8-15 and＜8 mg/kg,respectively;When the N fertilizer utilization efficiency was 30％-50％,and the yield target of grapes was 15.0-60.0 t/hm2,the ANAR for the soil N abundance and deficiency levels of from 1st to 8th were 0,14-90,27-180,41-270,54-360,68-450,81-540 and 95-630 kg/hm2,respectively.This study established the system of recommended N application rates for grapes in China based on ADI of soil nitrogen and provided scientific basis for soil testing and N fertilizer recommendation of grapes in China.关键词
