摘要
对山西省中部菜田土壤进行调查,并且取样分析,结果表明:土壤普遍存在碱解氮和速效磷的累积,速效钾、速效硼有减少的趋势,老菜田表现较为明显。祁县地区有机质、碱解氮含量偏低。依据土壤养分含量的丰缺状况:阳泉市、榆次、清徐、太原小店区菜田土壤碱解氮达到高含量水平的占30%以上,达到中含量水平的占50%,祁县地区碱解氮有73%的为极低含量水平。阳泉市、榆次土壤速效磷达到高含量水平的占80%以上。山西省中部菜田施肥技术应该控制氮、磷、增施钾肥和补施硼肥,大量施用秸秆类有机肥。
The investigation and the sampling analysis of the vegetable field＇ s soil in the middle of Shanxi show that, generally there exists the accumulation of the available N and the available P and the available K and the available B tend to reduce. It shows more evidently in the old vegetable fields. The content of the organ- ic matter and the available N is on the low side in Qi County. According to the abundance and the lack condi- tions of the soil nutrient content： In Yangquan, Yuci, Qingxu, and Xiaodian of Taiyuan there are more than 30% of the vegetable fields soil in which the content of the available N reaches the high level, and 50% in which the content of the available N reaches the middle level. In Qi County there is 73% of the vegetable fields soil in which the content of the available N reaches the extremely low level. In Yangquan and Yuei there is more than 80% of the vegetable field＇s soil in which the content of the available P reaches the high level. The fertilization technology of the vegetable fields in the middle of Shanxi province should control the N and P, increase the fer- tilization of K, supplement B and largely use organic fertilizer like the straw.
