摘要/Abstract

摘要： 设置田间小区试验,研究宜施壮商品有机肥对酸性土壤的改良效果及其在马铃薯（Solanum tuberosum L.）上的适宜用量。结果表明,试验地基础肥力较高,贡献率在62.98%~89.57%;用宜施壮商品有机肥代替部分甚至全部化肥完全可行;该有机肥与配方肥结合施用优于单纯施用有机肥,主要表现在马铃薯大薯率更高,相应提高了马铃薯的商品质量和商品率;采用Excel拟合的该有机肥用量与马铃薯产量的二次、三次回归方程相关性达到极显著水平,通过二次回归方程计算的该有机肥在马铃薯上的最大和最佳用量分别为9 660、7 993 kg/hm²,马铃薯最高和最经济产量分别为33 314、32 897 kg/hm²;该有机肥对改良酸化土壤有较好效果,随着用量增加土壤pH、盐基饱和度不断升高,交换性钾、交换性钙、交换性镁等盐基离子增加,而土壤交换性铝、有效锰含量逐渐降低,对抑制土壤铝、锰的毒害有一定作用。

Abstract: A field plot experiment was set to study the improvement effect of Yishizhuang commercial organic fertilizer on acid soil and the appropriate amount of it on potato. The results showed that the soil fertility was high, and the contribution rate ranged from 62.98% to 89.57%. It was completely feasible to replace part or even all chemical fertilizers with Yishizhuang commercial organic fertilizers.The combined application of the organic fertilizer and the formula fertilizer was better than the simple application of the organic fertilizer. The main performance was that the potato big potato rate was higher and the potato commodity quality and commodity rate were improved correspondingly. The quadratic and cubic regression equations of the amount of organic fertilizer and potato yields fitted by Excel reached extremely significant level. The maximum and optimal usage of the organic fertilizer on potatoes calculated by quadratic regression equation were 9 660 kg/hm² and 7 993 kg/hm², respectively. The highest and the most economic yield of potato were 33 314 kg/hm² and 32 897 kg/hm², respectively. The organic fertilizer had better effect on improving acidified soil. With the increase of the dosage, the soil pH and base saturation increased continuously. Exchangeable basic ions such as potassium, calcium and magnesium increased.However, the contents of exchangeable aluminum and available manganese in soil gradually decreased. It had certain effect on inhibiting the toxicity of aluminum and manganese in soil.

Key words: Yishizhuang, commercial organic fertilizer, potato（Solanum tuberosum L.）, suitable dosage
