不同底肥种类和覆盖方式对马铃薯产量的影响

为探讨缺水海岛地区的马铃薯生产方式,研究在不同底肥种类和不同覆盖方式处理下的马铃薯出苗期、产量和商品薯率。结果表明:选择适合的肥料种类作为底肥,能显著提高马铃薯产量,菜籽饼和复合肥均能提高马铃薯产量。覆盖白色地膜出苗最早,覆盖黑色地膜的生产方式能显著提高产量,覆盖白色地膜或黑色地膜均能显著提高马铃薯商品率。在舟山地区运用菜籽饼作为底肥、黑膜覆盖的生产方式,能显著提高马铃薯产量和商品薯率。

Effects of Different Types of Fertilization and MulchingMethods on Potato Yield

In order to investigate potato production methods in water-starved island areas,the potato emerging date,yield and commodity potato rate were studied with different basal fertilizers and mulching methods.The results showed that suitable basal fertilizer could improve potato yields significantly.Both rape seed cake and compound fertilizer could improve potato yields.The potato with white mulching film emerged earlier than others.Mulching with black film could significantly improve potato yields.In addition,mulching with either white or black films could significantly improve commodity potato rate.Using rapeseed cake as basal fertilizer and covering with black film could improve potato yield and commodity potato rate in Zhoushan region.
