The article presents the results of three-year observations of the sunflower growth and development in two innovative systems of sunflower cultivation: Clearfield and Express Sun and the use of two growth regulators - IzagriBor and Fertigrain in the subzone of southern chernozems of the Volgograd region. It was found in laboratory studies that the positive influence of the studied growth regulators is already manifested during the period of seed germination. The plant growth and development regulator Fertigrain had a positive influence on the length of roots and seedlings. Izagribor was less effective. The advantages obtained during the seeds germination then affect both the studied hybrids field germination and the yield. On average, over three-years-long observations, the Clearfield sunflower cultivation system (ES-Novomis hybrid + Eurolighting herbicide) turned out to be the most efficient. When cultivating sunflower by using this system, an average of 2.53 t/ha of oilseeds was obtained in three years, which is 9.7% more than the Express Sun system with the same combination of factors studied. Fertigrain was found to be the most effective regulator of plant growth and development. Its use increased yields in the Clearfield system by 15.0% and in the Express Sun system by 12.4% compared to the control.

伏尔加格勒地区南部黑钙土中生长调节剂对创新技术栽培向日葵生产力的影响

本文介绍了在伏尔加格勒地区南部黑钙土分区的两种创新型向日葵栽培系统 Clearfield 和 Express Sun 以及两种生长调节剂 IzagriBor 和 Fertigrain 中对向日葵生长和发育的三年观察结果。在实验室研究中发现,所研究的生长调节剂的积极影响已经在种子萌发期间表现出来。植物生长发育调节剂 Fertigrain 对根和幼苗的长度有积极的影响。Izagribor 效果较差。在种子萌发过程中获得的优势会影响所研究的杂种田间萌发和产量。平均而言,超过三年的观察,Clearfield 向日葵种植系统(ES-Novomis 混合动力 + Eurolighting 除草剂)被证明是最有效的。使用该系统种植向日葵时,三年平均获得油籽2.53 t/ha,比研究相同因素组合的Express Sun系统高出9.7%。Fertigrain 被发现是植物生长和发育的最有效调节剂。与对照相比,它的使用使 Clearfield 系统的产量提高了 15.0%,Express Sun 系统的产量提高了 12.4%。Fertigrain 被发现是植物生长和发育的最有效调节剂。与对照相比,它的使用使 Clearfield 系统的产量提高了 15.0%,Express Sun 系统的产量提高了 12.4%。Fertigrain 被发现是植物生长和发育的最有效调节剂。与对照相比,它的使用使 Clearfield 系统的产量提高了 15.0%,Express Sun 系统的产量提高了 12.4%。
