种植密度和施肥水平对高油大豆品质性状的影响

Effects of different planting densities and fertilizer levels on quality traits of high-oil soybean

  • 摘要: 采用二因素裂区试验,研究了不同种植密度和施肥水平对高油大豆品质性状的影响。结果表明,高油大豆的油脂含量随着种植密度的降低和施肥水平的升高而升高,蛋白质含量则相反; 不同品种间以农大15751油脂含量最高。中等种植密度处理硬脂酸和油酸含量较高,而高密度处理下亚油酸和亚麻酸含量较高,棕榈酸含量差异不显著。不同施肥水平对高油大豆脂肪酸含量影响较大,棕榈酸、硬脂酸和油酸含量在高肥处理下较高,亚油酸和亚麻酸在低肥处理下含量较高。

     

    Abstract: The effects of planting density and fertilizer level on the high-oil soybean quality traits were studied by the means of using a split plot experiment with two factors. The results show that oil content of the high-oil soybean is increased both with the decrease of planting density and the increase fertilizer level, while, protein content is decreased. There are significant differences of oil content among the cultivars, such as cultivar Nongda 15751 has the highest oil content. Contents of stearic acid and olcic acid are higher in the middle planting density treatment, while, contents of linoleic acid and linolenic acid are higher under the high density treatment. There is not significant difference of palmitic acid content among the different planting density treatments. Content of fatty acid of high-oil soybean is more affected by the fertilizer levels. Contents of palmitic acid, stearic acid and olcic acid are reached to their higher levels under the high fertilizer treatment, while, contents of linoleic acid and linolenic acid are reached to their higher levels under the low fertilizer treatment.
