我国葡萄土壤氮素丰缺指标和适宜施氮量初步研究OA北大核心CSTPCD
Preliminary study on abundance-deficiency index of soil nitrogen and appropriate N application rates for grapes in China
为建立我国葡萄测土推荐施肥系统,本研究检索了我国葡萄施氮的相关文献,提取土壤有机质、全氮和碱解氮含量,缺氮处理和施氮处理的产量数据,采用作物土壤养分丰缺指标推荐施肥系统研究新方法,研究了我国葡萄土壤氮素丰缺指标与适宜施氮量.结果表明:我国葡萄土壤有机质第1～8级丰缺指标依次为≥75、36～75、17～36、8～17、4～8、2～4、1～2和＜1 g/kg,土壤碱解氮第1～8级丰缺指标依次为≥288、158～288、87～158、48～87、26～48、15～26、8～15和＜8 mg/kg.当氮肥利用率为30％～50％、葡萄目标产量15.0～60.0 t/hm2时,氮素丰缺级别第1～8级土壤适宜施氮量分别为0、14～90、27～180、41～270、54～360、68～450、81～540和95～630 kg/hm2.本研究初步建立了我国葡萄土壤氮素丰缺指标推荐施肥系统,可为我国葡萄测土施氮提供依据.
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.
