摘要 针对盐碱地区施肥不合理的现状,以郑单958和德玉18为试验材料,采用田间小区试验方法,研究了滨海盐碱地上不同肥料对玉米体内养分浓度、养分分配及每形成单位籽粒产量收获养分量的影响。结果表明:施有机肥具有稳产高产作用,随着在不同玉米品种上施用不同有机肥,得出鸡粪处理较其他处理对玉米的稳产作用更为明显;不同肥料在2种玉米品种上对籽粒氮素、磷素和钾素浓度影响均表现为鸡粪〉绿蓝生物磷钾肥〉生物肥料〉冀微生物磷钾肥〉对照;玉米品种上分析ZD958体内养分含量大于DY18含量,不同玉米品种秸秆中的养分浓度以鸡粪效果最好,绿蓝生物磷钾肥次之;玉米收获产品中氮、磷含量在籽粒和秸秆中的分配比与产量均呈现较好的相关性(P〈0.05),钾表现不明显;玉米生长愈好,每形成单位经济产量消耗的氮、磷、钾就愈多,说明玉米对氮、磷、钾的利用都存在一定程度奢侈吸收。 In order to solve the problems of unreasonable fertilization in saline alkali area,this paper took ZD958 and DY18 as the study material and studied the effect of different organic fertilizer on nutrition concentration of corn,nutrient distribution and producing each unit seeds harvest the nutrient component by field trial. The results showed that: Using organic fertilizers achieved a high and stable yield level,as the different organic fertilizers applicate on different corn varieties; we could conclude that the treatment of chicken manure for stable yield was better than other treatments. Different fertilizers on two kinds of corn varieties had effect on seeds of N,P and K concentration,they all performed as chicken manure 〉green and blue creatures under phosphorus 〉bio-fertilizer 〉under phosphorus in microorganisms 〉the contrast; The nutrient concentration was different in corn varieties of straw,of which chicken manure was the best and green and blue creatures under phosphorus was the second. In the grain and straw the distribution ratio of nitrogen and phosphorus content had good correlation with corn yield,but it's not obvious in potassium; the better corn grown,the more N,P and K were consumed to form economic yield per unit. All these illustrated that the use of corn to nitrogen,phosphorus and potassium had luxury absorption on some degree.
