摘要

时事性。玉米发育不仅需要氮、磷、钾等宏量元素,还需要铜、钼、锰、钴、锌、硼等微量元素。在玉米栽培技术中,无论采用何种施用方式(播前种子处理或叶面施肥),微量元素肥料的有效性都很高。在微量元素中,锌在植物生命中尤为重要,因为锌的缺乏会导致节间减少、穗粒含量减少或穗不结实而导致生长放缓。目的。研究锌作为高浓度液体肥料在西部森林草原叶饲玉米中的施用效果及其对植物生长发育、叶面积形成、单株生产力和粮食产量的影响。材料与方法。在双因素试验中,以早熟DN Aton和中早熟DN Astra玉米杂交种为研究对象;在5 ~ 6叶期和8 ~ 9叶期喷施高浓度液体锌肥Chimic zinc。结果。结果表明,植株的线性尺寸由杂种的遗传特性决定,并与杂种的成熟期和矿质营养密切相关。其中,早熟杂交品种DN Aton在抽雄期株高为200.0 cm,对照中早熟杂交品种DN Astra - 210.7 cm,两次补锌后株高分别增加到225.1 cm和238.3 cm。早熟杂交种DN Aton的叶表面积从31.57万m2/ha增加到34.67万m2/ha,中早熟杂交种DN Astra -的叶表面积从33.59万m2/ha增加到36.99万m2/ha。试验变异体的生产穗数和产量结构指标的变化对籽粒产量的形成有一定的影响。由于在5-6叶期和8-9叶期对玉米进行叶面补锌,早熟杂交DN Aton玉米产量比对照提高了0.72 t/公顷(8.2%),中早熟杂交DN Astra玉米产量比对照提高了0.78 t/公顷(8.6%)。结论。在5 ~ 6叶期和8 ~ 9叶期叶片上施用高浓度液锌肥对玉米的生长发育、叶表面积和光合势的形成、每百株有效穗数的增加、产量结构要素指标的改善均有积极影响,有利于提高籽粒产量。关键词:玉米,杂交种,发育阶段,饲用,叶表面积,单产,产量

Effectiveness of zinc in foliar feeding maize in the Western Forest Steppe of Ukraine
Topicality. Maize requires not only macronutrients such as nitrogen, phosphorus and potassium, but also micronutrients such as Cu, Mo, Mn, Co, Zn, B, etc. for optimal development. In maize cultivation technologies, the effectiveness of micronutrient fertilisers is quite high, regardless of the application method (pre-sowing seed treatment or foliar feeding). Among the micronutrients, zinc is especially important in plant life, as its deficiency leads to a growth slowdown due to reduced internodes, reduced ear grain content or lack of ear setting. Purpose. To study the effectiveness of applying zinc in the form of a highly concentrated liquid fertiliser for foliar feeding maize and its impact on plant growth and development, leaf area formation, individual productivity, and grain yield in the Western Forest-Steppe. Materials and Methods. In a two-factor experiment, early-ripening DN Aton and mid-early DN Astra maize hybrids were studied; highly concentrated liquid zinc fertilizer Chimic Zinc was applied to spray crops in the 5–6 and 8–9 leaf stages. Results. It was established that the linear dimensions of plants are determined by the genetic characteristics of hybrids and significantly depend on their maturity group and mineral nutrition. In particular, the plant height of the early-ripening hybrid DN Aton in the tasseling stage was 200.0 cm and of the mid-early hybrid DN Astra – 210.7 cm in the control, while it increased to 225.1 and 238.3 cm, respectively, due to two-time zinc feeding. The leaf surface area of the early-ripening hybrid DN Aton increased from 31.57 to 34.67 thousand m2/ha, in the mid-early hybrid DN Astra – from 33.59 to 36.99 thousand m2/ha. Variation in the number of productive ears and yield structure indicators by experimental variants certainly influenced the formation of grain yield. Maize yield increased by 0.72 t/ha (8.2 %) in the early ripening hybrid DN Aton and by 0.78 t/ha (8.6 %) in the mid-early hybrid DN Astra compared to the control due to the zinc application for foliar feeding of maize in the 5–6 and 8–9 leaf stages. Conclusions. Foliar feeding maize in stages of 5–6 and 8–9 leaves with highly concentrated liquid zinc fertilizer Chimic Zinc has a positive effect on the plant growth and development, the formation of leaf surface area and photosynthetic potential, increases in the number of productive ears per 100 plants, improves indicators of yield structure elements, which contributes to higher grain yield.
