不同种类肥料对大豆生理特性和品质的影响

Effect of Different Kinds of Fertilizer on Soybean Physiological Characteristics and Quality

为探讨肥料对大豆生理特性和品质的影响规律,在大田条件下,以大豆品种黑农48为供试材料,设不施肥、常规施肥、有机肥、控释尿素和控释复合肥5个处理,对大豆叶绿素、地上生物产量、株高和品质的影响进行了研究。结果表明:有机肥对提高大豆株高影响最大,控释肥次之;控释复合肥对提高大豆叶绿素含量效果最好,控释尿素次之。成熟期各处理地上部生物量与对照相比差异达到显著水平。不同肥料均可以提高大豆籽粒品质,以有机肥对大豆籽粒蛋白质提高最大,除控释尿素外,与其它处理差异均达显著水平。与对照相比,控释复合肥能显著提高大豆籽粒脂肪含量,各肥料处理均能极显著提高大豆籽粒蛋脂总量。

To investigate the influence law of fertilizer on soybean physiological characteristics and quality,under field condition,Heinong48 was used as material,the treatments as follows：no fertilizer,conventional fertilizer,organic fertilizer,controlled release urea and controlled release compound fertilizers,the effects of soybean chlorophyll,above ground biomass,plant height and quality were studied.The result showed that organic fertilizer had the most important influence on improving soybean height,controlled release fertilizer took the second place.Controlled release compound fertilizer had the most important influence on raising soybean chlorophyll content,followed by controlled release urea.Above ground biomass of maturity compared with no fertilizer the difference reached significant level.Different fertilizer could improve the quality of soybean seed,organic fertilizer made the most raising in protein of soybean seed,except for controlled release urea,the difference between it with other treatments reached significant level.Controlled release compound fertilizer made the most raising in fat content of soybean seed,compared with no fertilizer the difference reached significant level.Different fertilizer could improve total of protein and fat of soybean seed,compared with no fertilizer the difference reached extremely significant level.
