摘要：

油菜是中国第一大自产植物油源，对于保障中国食用油安全十分重要，但当前油菜自给率严重不足，因而急需采用高产高效栽培措施提高产量，当前的研究多集中于氮磷钾等传统肥料，微肥的研究较少。本研究以甘蓝型油菜‘帆鸣1号’为试验材料，测定了不同微肥条件下的全生育期的生理生化指标以及产量性状，并两两间进行相关性分析。结果表明：5~6叶期—叶中的过氧化物酶、过氧化氢酶活性和花期—花中的超氧化物歧化酶活性大于0.8，说明相关性较高，可用与产量预测。5~6叶期—叶中的POD、CAT活性和花期—花中的SOD活性大于0.8且花期—花中叶绿素含量大于0.9时的施肥条件可提高产量。本研究结果为筛选适宜油菜生长的微肥和高产栽培提供了参考。

Abstract:

Rapeseed is the largest self-produced plant oil source in China, which is crucial for ensuring the safety of edible oil in China. However, the self-sufficiency rate of total rapeseed production is severely insufficient, so high yield and high efficiency cultivation measures are urgently needed to increase yield. Current research was mostly focused on traditional fertilizers such as nitrogen, phosphorus and potassium, with less research on micro fertilizers. This study used Brassica napus ‘Fanming 1’ as the experimental material to measure the physiological and biochemical indicators of the entire growth period and the yield traits under different micro-fertilizer conditions, and conducted correlation analysis between them. The results showed that the activities of peroxidase and catalase in leaves at 5-6 leaf stage and superoxide dismutase in flowers at flowering stage were more than 0.8, indicating that there had a high correlation, which could be used to predict the rapeseed yield. The fertilization conditions may increase the rapeseed yield when the POD and CAT activities in the leaves during the 5-6 leaf stage and the SOD activity in the flowers during the flowering stage were greater than 0.8, and the chlorophyll content in the flowers was greater than 0.9. The results of this study provided a reference for screening suitable micronutrient fertilizers and high-yield cultivation for rapeseed growth.
