墨竹工卡县耕地土壤有效硼含量状况分析

Analysis on Soil Available Boron Content in Maizhokunggar County

2007—2010年,结合测土配方施肥项目的实施,对墨竹工卡县耕地土壤有效硼含量进行了分析测定。结果表明:墨竹工卡县耕地土壤耕层有效硼含量低,有1/3的耕地土壤缺硼,且有效硼含量因行政区划、灌溉条件的差异而变化很大。根据土壤中硼的评价标准,提出了在施用有机肥的基础上,增施和补施硼肥、推广测土配方施肥等施肥对策。

Years from 2007—2010,combining with the soil testing and fertilizer projects,cultivated soil available boron content of Maizhokunggar County was analyzed.The results showed that cultivated soil available boron content of topsoil was low,nearly one third of the cultivated soil was short of available boron,and the change of available boron content was greater due to the administrative divisions,differences in irrigation conditions.According to the evaluation of boron in the soil standard,this paper proposed the application of organic fertilizer and put forward measures such as increasing the application of organic fertilizer,enhancing application of boron fertilizer and promoting formula fertilization by soil testing.
