有机肥和化肥配施对春油菜产量养分吸收量及品质的影响

The Effects of Organic Fertilizer and Fertilizer on Nutrient Absorption,Yield and Quality of Spring Rape

本文以春油菜青杂5号为供试材料,采用小区试验研究了有机肥和化肥配施对油菜产量、养分吸收和品质及土壤养分变化的影响。在本试验中,30%OM处理产量最高,达2431.5kg/hm2,显著高于其他处理,产量大小顺序为30%OM>50%OM>10%OM>0%,有机肥配施处理中籽粒产量不是随有机肥施用比例的增大而增加;单株有效角果数、千粒重、每角果粒数的变化规律与产量基本一致,其中每角果粒数与产量的相关系数达到0.8783;籽粒品质中氨基酸和蛋白质含量的变化规律与产量一致,而油分含量与其相反。试验结果还表明30%OM处理的产量、蛋白质、氨基酸含量均最高,土壤中速效养分吸收较完全,为较合适的有机无机肥配施处理。

This paper takes the spring rape hybrid 5 were used as material,the field contrast test and field experiments were carried out to study the organic fertilizer and fertlilzer on rape yield nutrient absorption and quality and the influence of soil nutrient change. In this experiment,30% OM were highest yield up to2431. 5 kg/hm^2,significantly higher than other of 30% OM 50% OM 10% OM 0%,organic fertilizer with processing of grain yield is not increase with the increase of organic fertilizer application ratio; individual effective pod numbers per spike,and the changing rule of the seed number per pod and yield,seed number per pod and production phase relationship is 0. 8783; the variation regularity of amnion acid and protein content in grain quality and yield,oil content,on the contrary,experimental results also showed that 30% of OM processing are the highest yield,protein,anmino acid content,soil available nutrient absorption is completes,is a more suitable organic inorganic fertilizer treatment.
