摘要

目的。为提高耐高酸性土壤条件下生长的新一代苜蓿品种新育卡种子的播种性能和产量性能提供理论依据。建立种子播质形成的特征。方法。现场,视觉,测量,重量,定量,测试方法,实验室,数学,统计。结果。通过施用速效型钙肥(Ca(OH)2 -水解酸度标准的0.5)和矿物质(N30P90K90),改善高酸度土壤条件下的植物营养,在右岸森林草原地带开发了新育卡苜蓿种子栽培技术的现代创新元素,种子产量达到了251 -301 kg/ha。在潜行期和出芽期用螯合微肥进行根瘤菌接种和叶面施肥,在2016-2018年平均使种子生产力提高25.9-56.8%,种子质量、发芽能、萌发力和生长力分别提高2-4个百分点;2 - 8;4 - 8;与对照组相比增加4-10%。结论。在土壤酸度较高的条件下,覆盖栽培下施用速效石灰石Ca(OH)2 -水解酸度标准的0.5和矿质肥料N30P90K90,结合播前细菌制剂种子处理Rhizobofit -种子和叶面施肥标准的0.15 l/公顷,在播种紫花苜蓿的潜行和出芽期施用抗胁迫Agrogumat - 0.4 l/公顷。平均而言,在2016-2018年,这为Sinyukha播种品种的苜蓿种子提供了最高产量- 288-301公斤/公顷,种子产量增加了96-109公斤/公顷,或50-57%。种子的播种质量,特别是千粒重、发芽能、发芽率和种子生长强度最高,达1.93 g,占68%;96和55%。

Formation of seed productivity and sowing qualities of alfalfa seeds depending on bacterization of seeds and foliar fertilization in conditions of the Forest-Steppe of Ukraine
Purpose. To theoretically substantiate the ways to increase the sowing and yield properties of alfalfa seeds of the new generation variety Sinyukha, tolerant to growing in conditions of high soil acidity. To establish features of formation of sowing qualities of seeds. Methods. Field, visual, measuring, weight, quantitative, test reaf method, laboratory, mathematical, statistical. Results. Modern innovative elements of Sinyukha alfalfa seed cultivation technology have been developed in the right-bank Forest-Steppe zone, which provides seed yield of 261-301 kg/ha, by improving plant nutrition in conditions of high soil acidity through applying fast-acting types of calcium fertilizers Ca(OH)2 – 0.5 of the norm for hydrolytic acidity, and mineral (N30P90K90), inoculation of seeds with bacterial preparation Rhizobophyte and foliar fertilization in the phase of stalking and budding with chelated microfertilizers, which on average in 2016-2018 provided an increase in seed productivity by 25.9-56.8%, mass of 1000 seeds, germination energy, germination and growth force, respectively, by 2-4; 2-8; 4-8; 4-10% compared to control. Conclusions. In conditions of high soil acidity, it is efficient to apply fast-acting limestone Ca(OH)2 – 0.5 of the norm for hydrolytic acidity and mineral fertilizers N30P90K90 under cover culture in combination with pre-sowing seed treatment with bacterial preparation Rhizobofit – 0.15 l of the hectare norm of seeds and foliar fertilization, twice in the phase of stalking and budding of the sown alfalfa with anti-stress Agrogumat – 0.4 l/ha. On average, in 2016-2018, this provided the maximum yield of alfalfa seeds of Sinyukha sowing variety – 288-301 kg/ha, the increase in seed yield was 96-109 kg/ha, or 50-57%. Sowing quality of seeds, in particular weight of 1000 seeds, germination energy, germination and seed growth strength were the highest and amounted to: 1.93 g, 68%; 96 and 55%.
