摘 要: | 与二十世纪八十年代初比,新疆农田土壤全氮含量有下降趋势,碱解氮含量普遍有所提高,但至少有50%的农田土壤碱解氮含量属于低水平,因此氮营养仍是制约新疆农作物产量的主要因素之一,必需继续合理施用好氮素化肥。

The Element N Content of Soil in Xinjiang's Farmland |

Abstract: | Comparing with 1980's,the present total nitrogen content of soil is inclining to descend in xinjiang farmland.However,N content,which is discomposed by alkali,is obviouscy increasing.But nowadays N content(discomposed by alkali)is low in 50 percent farmland in xinjiang. Lack of N content of soil is still a problem,as far as improving crop yield is concerned. |
