| 摘 要： | 在综合了大量国内外关于马铃薯植株需肥研究资料的基础上,运用Excel进行统计分析生产1 000 kg马铃薯块茎的植株需肥量及影响其需肥的因素。结果表明,概率较高的1 000 kg马铃薯需N、P2O5、K2O的区间分别是3.0～4.0 kg,1.00～1.50 kg,4.0～6.0 kg。影响马铃薯养分需求量的因素有土壤有机质含量、土壤pH值、年份、产量等。明确单位产量的马铃薯需肥量及其影响因素,以期对我国的马铃薯测土配方施肥提供依据,对马铃薯因环境条件的差异而确定施肥量提供有益的信息。

| Abstract: | Based on the previous research results on potato plant nutrient requirements,the amount of nutrient demands for harvesting 1 000 kg of tubers and the possible factors which influence the values were discussed and evaluated.The results indicated that 3.0-4.0 kg N,1.00-1.50 kg P2O5 and 4.0-6.0 kg K2O were needed for producing 1 000 kg of tubers,and the factors influencing the nutrient requirements included soil organic matter content,soil pH,years and yields.Understanding fertilizer requirement of unit yield ... |
