摘要
为了探究微量元素锌和硼对玉米果穗的影响,以豫单606为材料,采用盆栽试验,设置不施用锌肥和硼肥(对照,CK)、施用锌肥、施用硼肥、同时施用锌肥和硼肥4种处理,调查了玉米穗粒性状和品质的变化。结果表明,施用锌肥和硼肥,秃尖减少,行粒数增加,产量显著提高;施用锌肥籽粒长度增加,粒厚、百粒体积和百粒重降低,由于穗粒数提高,单穗产量增加;施用硼肥籽粒长度、百粒重、百粒体积和单穗产量均增加。与CK相比,单施锌肥、硼肥及锌肥和硼肥配施均能提高籽粒蛋白质含量;施用锌肥籽粒脂肪含量显著提高,施用硼肥籽粒脂肪含量降低;各施肥处理淀粉含量均无显著差异。与CK相比,施用锌肥或硼肥以及锌肥和硼肥配施显著提高了籽粒锌和硼的含量。本研究结果为锌肥和硼肥在玉米生产中的应用提供了参考。
In order to explore the effects of zinc and boron on ear traits of maize, a pot experiment was conducted with four treatments （application without zinc and boron, application of zinc, application of boron, application of zinc and boron） , using a hybrid Yudan 606 and the changes of ear-kernel traits and grain quality were investigated. The results showed that application of zinc or boron could obviously reduce bare tip length and increase kernels per row and yields. In terms of the kernel traits, applying zinc fertilizer increased kernel length, but decreased kernel thickness, 100-kernel volume and 100-kernel weight. The grain yield increased due to the increased kernel numbers per ear under the condition of applying zinc fertilizer alone. In contrast, kernel length, 100-kernel weight, 100-kernel volume and single ear yield were increased when applied boron alone. Quality characters of a grain were analyzed, and the results showed as follows： compared with CK, applying zinc fertilizer or boron fertilizer increased protein concentration in grain. Applying zinc fertilizer could significantly increase the content of fat, but applying boron fertilizer make it lower. Furthermore, there was no significant change on starch content. Compare with CK, application of zinc fertilizer or boron fertilizer also significantly increased zinc and boron content in grain. This study provides a theoretical basis for the application of zinc and boron in the production of maize.
