摘要:

为了探讨喷施新型叶面肥对作物产量和品质的影响及其机制,以"扬麦16号"为材料,研究小麦(Hordeum vulgare)抽穗扬花期或齐穗期喷施兴欣安利素液体叶面肥对小麦旗叶叶绿素(Chl)、可溶性蛋白(SP)和丙二醛(MDA)含量,抗氧化酶活性及籽粒产量和品质的影响。结果表明:喷施叶面肥明显提高小麦旗叶Chl和SP含量,提高超氧化物歧化酶(SOD)、抗坏血酸过氧化物酶(APX)和谷胱甘肽还原酶(GR)活性,降低叶片MDA含量,提高籽粒千粒重、产量以及籽粒蛋白质含量、湿面筋含量、沉降值和稳定时间,结合多菌灵的肥料喷施,上述指标变化趋势更明显,但差异未达显著水平(P>0.05)。喷施2次和1次在产量和品质指标上的差异也未达显著水平(P>0.05)。综上所述,在小麦生长后期喷施叶面肥,可明显提高旗叶的抗氧化功能,延缓衰老,维持较高的叶绿素含量,加大籽粒灌浆能力,从而提高小麦籽粒产量和品质。

Abstract:

In order to investigate the effects and mechanism of new foliar fertilizer on crop yield and quality, spring wheat (Yangmai 16) was as the experiment material. By applying foliar fertilizer with different dose and times, contents of chlorophyll (Chl), soluble protein (SP), malondialdehyde (MDA) and activities of antioxidant enzymes in flag leaves were studied, and the grain yield and quality were also determined. The results show:contents of Chl and SP, activities of superoxide dismutase (SOD), ascorbate-peroxidase (APX) and glutathione reductase (GR) in flag leaves were all increased under spraying fertilizer, and MDA contents in flag leaves were decreased significantly. Foliar fertilizer spraying increased 1 000-grain weight, grain yield, also increased protein content, wet gluten content, sedimentation and stabilization time of grain. However, these above-mentioned effects were more obvious when fertilizer spray was combined with carbendazim, and these differences all did not reach significant level (P>0.05). There was no significant difference in yield and quality between spraying twice and once (P>0.05). Thus, foliar fertilizer application at flowering or heading stage can prevent leaf senescence and improve chlorophyll content by increasing the leaf antioxidation, and enhance grain filling, grain yield and quality.

Key words: wheat, foliar fertilizer spraying, antioxidation, yield, quality
