摘  要:
在川西南冬季马铃薯种植区,开展马铃薯专用控释配方肥不同用量对青薯9号增产效应的对比试验。试验结果表明,以每667 m~2施用60 kg马铃薯专用控释配方肥作底肥为最佳施肥方案,该处理的平均单株质量、商品薯率最高,平均鲜薯产量为2 114.0 kg/667 m~2,比对照(不施肥)增产1 063.5 kg/667 m~2,增幅为101.2%。

摘  要:
We carried out the comparative test to study the effects of different dosages of controlled-released fertilizer specially used for potato on yield increasing of Qingshu No.9 in winter potato planting area of southwest Sichuan. The results showed that, the best fertilization scheme was applying 60 kg/667 m2controlled-released fertilizer specially used for potato as base fertilizer. The treatment had the heaviest average single plant weight and highest marketable tuber rate,and the fresh tuber yield was 2 114.0 kg/667 m2, which was increased by 1 063.5 kg/667 m2 compared to the control treatment(no fertilizer application), with the yield increasing rate of 101.2%.
