摘要

本文介绍了罗斯托夫地区南部冬豌豆栽培技术要素(播种时间、播种率)的研究结果。在2019-2020年和2020-2021年的两个农业年份进行了田间试验。研究对象是越冬豌豆品种“Fokus”、“Faeton”、“Zimus”。本研究的目的是研究在罗斯托夫地区南部的条件下,播种时间和播种率对越冬豌豆田间发芽和收获保存的影响。试验区土壤为黄土状壤土上的普通钙质重壤土黑钙土。耕作层腐殖质含量为3.36%,pH为7.0,P2O5为24.4;K2O为360 mg/kg土壤。播种时间对田间发芽有一定影响。在多年的研究中,平均而言,第一期的田间发芽率为27.0%至93.5%,第二期为33.6%至91.0%,第三期为31.5%至94.5%。播种时间对田间发芽的影响份额从品种“Faeton”的9.4%到品种“Fokus”的22.5%不等。越冬豌豆在第一个播种期的收获保存率为93.8%(“Zimus”)至94.8%(“Faeton”),在第二个播种期为95.0%(“Faaton”)至95.5%(“Fokus”),第三个播种期,收获保存率从品种“Fokus'的94.7%至品种“Zimus'的95.6%。播种时间对收获保存的影响份额从“Zimus”品种的5.4%到“Fokus”品种的23.4%不等。在多年的研究中,平均而言,在100万种胚的播种率下,“Faeton”品种的田间发芽率最高(93.5%)。种子/公顷。在100万胚的播种率下,品种“Faeton”的保存率最高(96.5%)。第二播种期种子/公顷。

Effect of sowing time and seeding rates on field germination and harvesting preservation of wintering peas in the southern part of the Rostov region
The current paper has presented the study results of the elements of cultivation technology (sowing time, seeding rate) of wintering peas in the southern part of the Rostov region. Field trials were carried out during two agricultural years in 2019–2020 and 2020–2021. The objects of research were the varieties of wintering peas ‘Fokus’, ‘Faeton’, ‘Zimus’. The purpose of the research was to study the effect of sowing time and seeding rates on field germination and harvesting preservation of wintering peas in the conditions of the southern part of the Rostov region. The soil of the experimental plot was ordinary calcareous heavy loamy chernozem on loess-like loams. The content of humus in the arable layer was 3.36%, pH was 7.0, P2O5 was 24.4; K2O was 360 mg/kg of soil. The sowing time had an impact on field germination. On average, over the years of research, field germination in the 1st period ranged from 27.0 to 93.5 %, in the second from 33.6 to 91.0 %, in the third from 31.5 to 94.5 %. The share of the effect of the sowing time on field germination ranged from 9.4% for the variety ‘Faeton’ to 22.5 % for the variety ‘Fokus’. The harvesting preservation of wintering peas ranged from 93.8 % (‘Zimus’) to 94.8 % (‘Faeton’) in the first sowing period, in the second sowing period it ranged from 95.0 % (‘Faeton’) to 95.5 % (‘Fokus’), in the third, the harvesting preservation ranged from 94.7 % for the variety ‘Fokus’ to 95.6 % for the variety ‘Zimus’. The share of the effect of the sowing time on harvesting preservation ranged from 5.4 % for the variety ‘Zimus’ to 23.4 % for the variety ‘Fokus’. On average, over the years of study, the maximum field germination was observed for the variety ‘Faeton’ (93.5 %) at a seeding rate of 1.0 million germin. seeds/ha. The best preservation was identified for the variety ‘Faeton’ (96.5 %) at a seeding rate of 1.0 million germin. seeds/ha in the second sowing period.
