摘要: 为明确炭基肥在马铃薯生产上的应用效果,以克新1号品种为材料,采用随机区组设计,研究了大田条件下0(CK),300(M1),600(M2),900(M3),1 200(M4) kg/hm2炭基肥及等量N、P、K化肥(H1、H2、H3、H4)对马铃薯田0 ~40 cm土层土壤容重、孔隙度和养分的影响。结果表明,随着土壤深度的增加,土壤容重逐渐增大,土壤孔隙度逐渐降低,养分含量降低;各施肥处理均有利于改善土壤结构和养分含量,与CK相比,随着施肥量的增加各层土壤容重降低,总孔隙度、有机质、碱解氮、有效磷和速效钾的含量增加。等量氮磷钾条件下,施炭基肥的土壤容重的降低幅度和孔隙度增加幅度明显高于化肥处理;施炭基肥处理的养分含量随生育期的推进呈低—高—低的变化,而施化肥处理却逐渐降低,苗期施化肥处理的土壤养分含量高于施炭基肥的处理,块茎增长期和成熟收获期则是施炭基肥处理的土壤养分含量均高于施化肥的处理。在该试验条件下,炭基肥施用量为1 200 kg/hm2时马铃薯田土壤理化性质最优,可作为阴山北麓地区马铃薯种植的推荐施肥量。

关键词: 炭基肥, 马铃薯, 容重, 孔隙度, 土壤养分

Abstract: In order to understand application effect of carbon based fertilizer in potato production,random block design was adopted to study the effects of the carbon based fertilizer on soil bulk density and porosity and nutrient of Kexin 1 by applying 0,300,600,900,1 200 kg/ha of this fertilizer and the same amount of N,P,K fertilizer.The results showed that:With the increment of soil depth,soil bulk density increased,soil porosity and the contents of soil nutrient gradually decreased.With the increment of fertilizer,soil bulk density decreased,soil porosity and nutrient increased than that of CK.At the same amount of N,P,K,reduce the rate of soil bulk density and increase the rate of soil porosity of treatments with carbon based fertilizer were obviously higher than chemical fertilizer.Treatments with carbon based fertilizer showed a trend of lower-high-lower,but treatments with chemical fertilizer decreased.Soil nutrients of the treatments with chemical fertilizer were higher than that of treatments with carbon based fertilizer of the same amount of N,P,K in seedling stage of potato.Soil nutrients of the treatments with carbon based fertilizer were higher than that of treatments with chemical fertilizer of the same amount of N,P,K at the inflated period of tuber and harvest time.In the experiment,the soil physicochemical properties of potato of 1 200 kg/ha treatment were better,and it was the suitable match for Wuchuan areas in Inner Mongolia.
