生物复合专用肥对马铃薯生长及生理的影响

Effects of Biological Compound Fertilizer Treatments on Growth and Physiology of Potato

以辽宁地区栽培常见马铃薯品种"尤金"为试验材料,设计5个不同用量的生物复合专用肥肥料处理(0,900,1350,1800,2250 kg·hm^(-2)),研究其对马铃薯生长指标、生理指标和产量的影响.结果表明,生物复合专用肥能明显增加马铃薯株高、茎粗、叶面积、光合指标,可以显著提高马铃薯的生物量、单株结薯数、单株产量;2250 kg·hm^(-2)施肥水平处理的生物量、单株结薯数明显高于其他处理;可溶性蛋白含量在1800 kg·hm^(-2)和1350 kg·hm^(-2)施肥水平下表现最好;淀粉和可溶性糖在1800 kg·hm^(-2)施肥水平下表现最好.总体上看,在1800kg·hm^(-2)生物复合专用肥施肥水平下马铃薯各项指标表现最优秀,能够获得更高产量和品质,在马铃薯栽培上作用效果最好.

Using Eugene,a common potato variety cultivated in Liaoning Province,effects of five biological compound fertilizer treatments(0,900,1350,1800,2250 kg·hm-2)on potato growth index,physiological index and yield were determined.Biological compound fertilizer significantly increased plant height,stem diameter,leaf area and photosynthetic index,the biomass of potato,the number of tubers per plant and the yield per plant.Under 2250 kg·hm-2 fertilization treatment,the biomass and the number of tubers per plant were significantly higher than that of other treatments and the content of soluble protein was the best at the fertilization levels of 1800 kg·hm-2 and 1350 kg·hm-2.Starch and soluble sugar had the best performance at 1800 kg·hm-2 fertilization level.On the whole,under the fertilizer application level of 1800 kg·hm-2 biological compound fertilizer,the potato had the best performance,which could obtain higher yield and quality,and had the best effect on potato cultivation.
