摘要
为探索缓释肥在马铃薯上的作用,2009年贵州省土壤肥料研究所引进施可丰牌缓释肥和氮肥抑制剂(一种氮肥缓释剂),设置田间小区试验研究缓释肥在马铃薯上的应用效果。结果表明:施可丰牌缓释肥在一次性施肥的情况下,对马铃薯增产效果显著,并能较大幅度提高肥料利用率,施可丰牌缓释肥用量(按总养分量折算)在比常规施肥减少20%用肥量的情况下仍有5.6%的增产效果。初步认为,种植马铃薯施用施可丰牌缓释肥有节本、增效、省工的作用。
The plot experiment was conducted to study the effect of Shikefeng slow-release fertilizer and nitrogen inhibition agent on application of potato for exploring application of slow-release fertilizer in potato production. The results showed that applying Shikefeng slow-release fertilizer once could significantly increase potato yield and raise the fertilizer utilization rate by a large margin, and the potato yield applying shikefeng slow-fertilizer with 80 % nutrition amount of conventional application amount still increased by 5,6 % compared with that applying conventional application amount, Therefore, applying Shikefeng slow-release fertilizer had the low cost, high efficieney and labor-saving effect in potato production.
