| 摘 要： | 应用GPS和GIS定位技术,对黑龙江省松嫩平原和三江平粮食主产区土壤按20 km×20 km的网格进行取样,对土壤速效养分状况与分布特征进行了研究。结果表明,黑龙江省松嫩平原和三江平原粮食主产区土壤缺氮面积占87.9%,缺磷面积占46.1%,缺钾面积占72.4%,缺硫面积占86.1%,缺锌面积占61.3%,缺硼面积占43.6%。应采用松嫩平原地区重点补磷和锌,三江平原地区重点补硼,中南部地区重点补氮磷钾和全面补硫的施肥策略。

| Abstract: | Directed by information technology GIS and GPS,soil samples were collected on a 20 km×20 km grid in Songnen plain and Sanjiang plain in Heilongjiang province to study soil nutrients status and distribution.The result showed that nutrients deficient acreage proportion of available N,P,K,S,Zn and B were 87.9%,46.1%,72.4%,86.1%,61.3% and 43.6%,respectively.So the strategy of fertilization should be laid on specially supplying P and Zn in Songnen plain,specially supplying B in Sanjiang plain,specially supplying N,P and K in the central and the South of the province,specially supplying S in the whole province. |
