摘要
针对黑龙江省农田土壤pH下降问题,结合研究结果和生产实践,对农田黑土酸化的原因进行了综合论述,得出种植制度不合理和大量偏施氮肥是引起农田土壤酸化的主要原因,大力推广平衡施肥、合理轮作、增施有机肥、秸秆还田、种植耐酸植物等是解决农田土壤酸化的有效途径。
The reason of black soil acidification in Heilongjiang province according to the investigating result and production practise aiming at the decrease of pH was investgated.The results showed that illogical of planting system and the large amount using of nitrogen fertilizer were the mainly reasons of soil acidification.The effective tracks to settle the problem were soil testing formula fertilization,balanced fertilization,logical rotation,using more organic fertilizer and planting acid tolerance plant.
