西藏土壤肥料工作的研究与展望

Research and Prospect on the work of soil and fertilizer in Tibet

西藏因其独特的地理环境,具有土壤类型多,成因复杂等特点,与其相关的研究工作不仅具有很高的学术价值,在提高作物产量上也具有积极的现实意义。当前,通过第二次土壤养分普查和测土配方等项目基本弄清了土壤中氮磷钾等大量元素的含量,钾肥的用量逐渐增加,化肥配比趋于合理,但也存在土壤有机质下降,化肥利用率不高等问题,需要继续在土壤定位监测、新型化肥研发、提高土壤肥力等方面进行重点研究,以期为农业生产做出更多的贡献。

Because of its unique geographical environment, there were many soil types in Ti- bet. The researching about Tibet soil not only had high academic value, but also had positive sig- nificance in improving crop yields. Currently, by the second survey of soil nutrients and soil tes- ting project in Tibet to clarify the content of the soil in NPK elements, gradually increase the a- mount of potash, fertilizer ratio tends to be reasonable, but there were also soil organic matter decline, fertilizer utilization rate was not high, need to continue to monitor the positioning in the soil, the new fertilizer research and development, improve soil fertility and other aspects of key research, in order to make more contributions in agricultural production.
