摘要

本文介绍了通过优化栽培技术的基本要素来提高葵花籽产量的科学问题的田间试验研究。该研究于2020-2021年期间在VNAU研究领域以位于Agronomichne Vinnytsia地区村庄的NDG“Agronomichnenske”为基础进行。以早熟向日葵成熟积分和拉夫森两种杂交品种为研究材料,对其行距和播种量进行了研究。为了实现这一目标,使用了现场、实验室、统计和计算方法。采用实验室法测定了采收质量及其结构、环境资源利用效率。用统计学方法对所得研究结果的可靠性进行了评价。采用计算比较法确定了工艺要素的经济效益。播种行距为45 cm的向日葵时,杂种Integral的生长季为108 d,杂种Slavson的生长季为95 d。行距为70 cm时,两种杂交种植株的植被均减少2 ~ 6 d。结果表明,随着作物厚度从5万~ 9万/ ha增加,杂种Slavson株高从179.1增加到190.4 cm,杂种积分从184.1增加到196.9 cm。行距70 cm、播种密度为5万株/ ha - 72.6 g的早熟杂交积分品种1000粒重较大,播种密度为9万株/ ha - 56.1 g时该指标最低。向日葵的产量取决于单位面积的花序数、每花序的种子数、平均重或千粒重等结构要素,种子质量主要由脂肪和蛋白质含量决定。综上所述,在45和70 cm行距下,杂交水稻的最佳播种密度为- 7万粒/公顷。播种70 cm时,杂交品种Integral的种子产量较高,为2.72 t / ha。

INFLUENCE OF TECHNOLOGICAL APPROACHES OF GROWING ON SUNFLOWER SEED PRODUCTIVITY
The article covers an experimental field study of scientific issues - increasing the yield of sunflower seeds by optimizing the basic elements of cultivation technology. The research was carried out in the period 2020-2021 in the research field of VNAU on the basis of NDG "Agronomichnenske", which is located in the village of Agronomichne Vinnytsia region. Two hybrids of early-ripening sunflower maturity Integral and Slavson were studied in the studies of row spacing and sowing density. To achieve this goal used field, laboratory, statistical and computational methods. The quality of the harvest and its structure, the efficiency of the use of environmental resources were determined by the laboratory method. The reliability of the obtained research results was assessed by a statistical method. The economic efficiency of the studied elements of the technology was determined by the calculation-comparative method. It was found that when sowing sunflowers with a row spacing of 45 cm, the growing season of the hybrid Integral is 108 days, and the hybrid Slavson - 95 days. With a row spacing of 70 cm, the vegetation of plants of both hybrids is reduced by 2-6 days. It was observed that with the thickening of crops from 50 to 90 thousand / ha, the plant height of the hybrid Slavson increases from 179.1 to 190.4 cm, and the hybrid Integral from 184.1 to 196.9 cm. Larger weight of 1000 seeds was provided by the early-ripening hybrid Integral with a row spacing of 70 cm and a sowing density of 50 thousand plants / ha - 72.6 g, and the lowest value of this indicator was at a density of 90 thousand plants / ha - 56.1 g. Sunflower yield depends on structural elements such as number of inflorescences per unit area, number of seeds per inflorescence, average weight or weight of 1000 seeds, and seed quality is mainly determined by fat and protein content. We state that the optimal sowing density of hybrids Integral Slavson and for sowing with a row spacing of 45 and 70 cm was - 70 thousand / ha. Higher seed yield for sowing 70 cm was provided by the hybrid Integral - 2.72 t / ha.
