化肥与农药减施替代集成技术对马铃薯生长及产量的影响

Effect of Chemical Fertilizer Reduction and Pesticide Substitute Integrated Technology on Potato Growth and Yield

针对马铃薯种植范围广、肥药使用量较大的特点,雷力公司应用海藻有机肥、微生物菌剂、褐藻双寡糖和壳寡糖等产品组成雷力马铃薯肥药减施替代集成技术,开展马铃薯化学肥料替代及减施技术小区试验,研究肥药减施替代集成技术对马铃薯生长动态及产量的影响。结果表明,与常规用肥用药对照相比,在施肥量相同、农药施用量减少30%的条件下,采用雷力集成技术种植的马铃薯植株染病率降低3.86个百分点,产量增加3.96%;在施肥量降低17%、农药施用量减少30%的条件下,采用雷力集成技术种植的马铃薯植株染病率降低15.30个百分点,产量增加3.12%。

In view of the wide planting range of potato and the large amount of fertilizer used,Leili company applied seaweed organic fertilizer,microbial inoculum,alga disaccharide oligosaccharide and chitooligosaccharide to constitute the Leili potato fertilizer and pesticide reduction substitute integrated technology.A plot experiment was conducted to study the effect of Leili potato fertilizer and pesticide reduction substitute integrated technology on the growth and yield of potato.The results showed that,compared with the conventional application of fertilizer and pesticide,under the condition of the same fertilizer application rate and the reduction of pesticide application rate by 30%,the infection rate of plants in the plot under Leili integrated technology decreased by 3.86 percentage points,and the yield increased by 3.96%.Under the conditions of 17% reduction of fertilizer application and 30% reduction of pesticide application,the infection rate of the plot plants under Leili integrated technology decreased by 15.30 percentage points,and the yield increased by 3.12%.
