摘要
按照《到2020年化肥使用量零增长行动方案》的要求,为探索菜用薯尖减肥增效最佳模式提供技术支撑,本文设置了空白对照、农户习惯施肥、测土配方施肥和有机肥+化肥等4个处理,对薯尖性状、产量、效益等进行分析。结果表明,施用有机肥不仅可以减少化学肥料用量,改良土壤性质,提高土壤肥力,而且不减少薯尖产量,甚至可以增加产量。
According to the requirements of 《Action Plan for Zero Growth of Fertilizer Use by 2020》,in order to provide the technical support for exploring the best model for fertilizer decrease and efficiency improvement of vegetable sweetpotato,four treatments were set up in this paper,including blank control,farmers′ habit fertilization,soil testing formula fertilization and organic fertilizer+chemical fertilizer. Meanwhile,the characters,yield and benefit of vegetable sweetpotato were analyzed. The results showed that,application of organic fertilizer not only could reduce the amount of chemical fertilizer,improve soil properties and fertility,but also couldn′t reduce the yield of vegetable sweetpotato or even can increase yield.
