不同栽培方式对冬种马铃薯产量和品质的影响

Effect of the different cultivation methods on yield and quality of winter planting potato

采用常规法、一次施肥法、免耕法、免耕+喷施磷酸二氢钾4种方式栽培费乌瑞它马铃薯,研究不同栽培方式对马铃薯产量和品质的影响。结果表明:采用免耕+喷施磷酸二氢钾方式栽培的马铃薯大中薯率占51%以上、增产31.34%、品质较佳;免耕法和一次施肥法的马铃薯产量分别降低9.04%、9.54%。

The effects of four cultivation methods（conventional cultivation method,one-fertilization method,no-tillage and no-tillage ＋ spraying KH2PO4） on yield and quality of winter planting potato were studied.The experimental results showed that the Large-medium sized rate of potato was more than 51%,yield increased by 31.34%,and the quality of potato was better in the method of no-tillage ＋ KH2PO4.The potato yield was decreased 9.04% in no-tillage method and 9.54 % in one-fertilization method.
