Abstract:

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/hm2, 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.
