液体肥在马铃薯生产上的应用效果研究

Experimental study on effect of liquid fertilizer on production of potato

在田间试验条件下,以滴灌施用和传统淋施方式,研究了液体肥对马铃薯生长、产量和品质的影响。结果表明：与不施液体肥的T1处理相比,滴施和淋施液体肥的T2、T3处理显著增加了马铃薯块茎中N、P、K、Ca、Mg的累积量;滴施和淋施液体肥的T2、T3处理显著增加了马铃薯块茎产量,增幅为91.18%~152.48%,经济效益显著提高。研究结果对液体肥和滴灌施肥技术在马铃薯生产上的推广应用具有重要意义。

Drip-fertigation and traditional irrigation and fertilization were compared for the effects of liquid fertilizer on potato growth,production and quality under field conditions.The results obtained were as follows： applying liquid fertilizer（including T2 and T3） increased the N,P,K,Ca,Mg accumulation in the potato tuber in comparison with the treatment of traditional irrigation and fertilization（T1）.T2 and T3 significantly increased potato tuber yield by 91.18%~152.48%,thereby significantly increasing the economic benefit.These results lay a sound foundation for extension of the liquid fertilizer and drip-fertigation technique in potato production.
