不同有机无机肥配比对‘湘杂油763’产量、叶绿素和碳氮代谢产物的影响研究

为确定优质冬油菜新品种的合理有机肥配比，同时促进畜禽粪便的肥料化利用，本文采用大田小区试验，在猪粪型有机肥代替50%、30%、10%的化肥氮条件下，研究了不同有机无机肥配比对‘湘杂油763’产量、叶绿素和碳氮代谢产物的影响。结果表明：用猪粪型有机肥代替10%的化肥氮处理的产量最高，为2055.00 kg/hm2，与其他处理间的差异达到了显著水平，纯无机肥处理的产量位居第二；比较3个配施有机肥处理的产量，随着有机肥施用比例的增加而产量减少。叶绿素a、叶绿素b和总叶绿素含量均随有机肥用量的增加而逐渐降低，可溶性糖含量的变化趋势则与叶绿素含量相反，施用有机肥处理的游离氨基酸含量和总量基本低于纯无机肥处理。游离氨基酸总量以纯无机肥处理最高，10% OM处理次之。总体来看，合理的有机无机肥配比（10% OM处理）下，可溶性糖、游离氨基酸总量都较高，从而保证产量也达到最高值。因此，在本试验所设处理中，10%的氮素养分为有机肥替代的最合理比例。

The Study on the Effect of Combined Application of Organic and Inorganic Fertilizer on Yield, Chlorophyll, Metabolite of Carbon and Nitrogen of ‘Xiangzayou763’ Rapes

To determine reasonable organic fertilizer matching of quality rapeseed, and promote utilization of poultry and animal feces, the field experiment was conducted to study on the effects of combined application of organic fertilizers and inorganic fertilizer on yield, chlorophyll, and metabolites of carbon and nitrogen of ‘ xiangzayou763 ’ rapes in condition that organic manure instead of 50%, 30% and 10%. The results showed that the highest yield was 2055.00 kg/hm 2 , 10% OM treatment was highest than other treatments, following with pure chemical fertilizer. Compared three types of organic fertilizer processing yield, with the increased of application proportion of organic manure, the yield was reduced. The contents of chlorophyll-a, b and total chlorophyll were reduced with the amount of fertilize, the trend of soluble sugar content against with chlorophyll content. The content and total of free amino acids were less than pure chemical fertilizer processing. Pure chemical fertilizer processing had the highest of the free amino acid total, following with 10% OM processing. Overall, with the reasonable organic and inorganic fertilizer ratio （10% OM treatment） processed, the total of soluble sugar, free amino acid was high, thus ensured the highest output. Therefore, 10% of the nitrogen literacy was the most reasonable organic ratio in this experiment.
