摘要
根据沁州黄优质小米典型种植区不同的地形、土壤属性、肥力水平,确定21个监测点,取0～20 cm和20～40 cm深土壤,对其中的主要营养元素状况进行研究,结果表明,沁州黄优质小米产地土壤相对贫瘠,综合肥力水平中等偏低,特别是对谷子的品质和产量影响比较大的有效锌和有效硼含量低下,建议在当地习惯施肥的基础上,增施有机肥,调整氮、磷配比为1∶(0.6～0.7),每公顷增施150 kg钾肥、7.5 kg锌肥和7.5 kg硼肥。
21 monitoring spots have been defined based on topography, soil character and fertility level in typical cultivation areas, and the main nutritional elements were determined for soil samples collected from 0 - 20 cm and 20 - 40 cm layers. The resuits showed that： soils in Qin-zhou-huang millet cultivation base were relatively impoverished with middle to low integrated fertility, especially with low available boron which had considerable important effect to millet quality and yield. It was suggested, based on local conventional fertilization, to increase the organic manure in base fertilizer, to take a reasonable N to P ratio of 1 ： （0.6 - 0.7 ）and a proper fertilizer application rate were K 150 kg, Z and B 7.5 kg respectively.
