摘要
通过小区试验和大田对比试验,对马铃薯施钾的肥效效应进行了研究.结果表明:小黄泥灰泡土施用钾肥,小区试验马铃薯增产3.93～8.63 t/hm2,增产幅度为16.75%～36.79%,每1 kg氯化钾可增产马铃薯9.86～35.36 kg;大田对比试验施钾肥,马铃薯增产8.93～9.24 t/hm2,增幅37.54%～58.60%.结果还表明,施钾可以增加马铃薯薯块中钾与淀粉的含量,提高马铃薯的耐贮性,间接提高马铃薯的经济效益.
The study on the effect of potash fertilizer on potato yield was carried out through field experiment and comparing trial. The result showed:potato yield was increased 3.93~8.63 t/ha by applying potash in plot test. And it increased by 16.75%~36.79% compared with the yield in non-potassium treatment. The yield increased 9.86~35.36 kg of per 1kg KCl applied. The yield in field comparison trial was increased 8.93~9.24 t/ha in percentage was 37.54%~58.60%. The result also showed:starch and (potassium) contents in potato can be raised by using KCl. The storage period showed longer than that of non-KCl. Then the income from potato can be raised indirectly.
