不同栽培模式对马铃薯产量的影响

摘要

以马铃薯品种‘威芋5号’为试验材料，分别进行垄距为75 cm和65 cm的整薯和切块栽培试验，并进行氮磷钾“3414”组合施肥研究，得出效益最优肥料配施组合为：在垄距75 cm的整薯栽培模式下，施N 6 kg/667 m2、P2O57.5 kg/667 m2、K2O 12 kg/667 m2的产量最高，达2765 kg/667 m2。%With potato variety Weiyu-5 as test material, cultivation test under different ridge distances for the whole potato and diced potato were carried out. Combined application of nitrogen, phosphorus and potassium was studied with “3414” experiment method. The best combination of fertilizers was 6 kg/667 m2 of N, 7.5 kg/667 m2 of P2O5, 12 kg/667 m2 of K2O with whole potato under ridge distance of 75 cm. It got the highest yield of 2 765 kg/667 m2.
