不同施肥组合对马铃薯产量及品质的影响

Effects of Different Fertilizer Combinations on Yield and Quality of Potato

为减少化肥施用量,筛选优良新型肥料,实现马铃薯绿色稳产增效的目标,以中薯18号、青薯9号和艾玛土豆3个马铃薯品种为供试品种,研究不同复合肥+生物肥的施肥组合对马铃薯产量及品质的影响。结果表明,F2与F4处理下,马铃薯的产量未受到明显影响,F2处理下马铃薯的商品薯率高,品质最优,又能降低投入成本,为马铃薯优质施肥组合。F4处理下马铃薯的部分品质表现不佳,但施肥量最少,投入低,使用效率高,可对其施用方式进一步研究。

In order to reduce the amount of chemical fertilizer,screen new fertilizers and achieve the goal of green and stable production and efficiency of potatoes,three potato varieties,Zhongshu 18,Qingshu 9 and Emma Potato,were used to study the effects of different fertilizer combinations of compound fertilizer and biological fertilizer on the yield and quality of potatoes.The results showed that under F2 and F4 treatments,the yield of potatoes was not significantly affected,the marketable tuber percentage of potatoes was high,the quality of potatoes was the best,and the input cost could be reduced.The potato fertilization combination with high quality was obtained from this experiment.Partial quality performance of potatoes treated with F4 was not good,but the application amount was the least,the input was low,and the use efficiency was high.The application method of F4 could be further studied.
