摘要: 采用钾肥(K2O 19 kg/667m^2)总用量不变,分不同次数施用试验,研究对马铃薯农艺性状及产量的影响,结果表明随着钾肥施用次数的增加,马铃薯单株结薯数、单株大薯个数及重量、产量均呈增加的变化趋势。综合考虑多次施肥成本增加的因素,钾肥施用5次效益最佳。

Abstract: Effect of different potassium applied times on the agronomic characters and yield of potato was studied when the total potassium fertilization was 19 kg/667m^2. The results showed that with the increase of K application times, the tuber number per plant, the percentage of big tubers and the tuber yield presented the trend of increases. Comprehensive analyzing the cost and benefit, 5 times potassium application showed the optimum benefit.
