摘要
试验田位于康斯坦察县Amzacea的S.C. SPORT AGRA s.r.l.开发中心，位于高速公路38,20公里处。远离保加利亚边境。康斯坦察县在罗马尼亚种植向日葵作物的地表重量最大，在10-12%之间。罗马尼亚最干旱的地区是Dobrogea(1961-1990年平均降雨量为464毫米)。近年来的气候变化加剧了这一趋势。在我们的实验中，杂交品种的数量在2018年是15种，在2020年是20种。创世纪已经在2020年的两个时期种植。延期种植时，产量减少303公斤/公顷。本研究的目的是:(i)在令人难以置信的干燥条件下杂交向日葵的行为，(ii)观察杂交向日葵的产量和对主要病原体——核菌核菌、helianthi、Orobanche cumana的攻击的行为，(iii)种植日期如何影响产量，(iv)使用杀虫剂的重要性，(v)经济数据。
RESEARCH OF CLIMATE CHANGES – SUNFLOWER HYBRIDS 2018-2020 IN CONSTANTA COUNTY, SOUTH EAST OF DOBROGEA, ROMANIA
The experimental field was placed in Amzacea, Constanta County at S.C. SPORT AGRA S.R.L., Center of Development, on the highway 38, 20 km. far from Bulgarian border. Constanta County had the largest weight regarding the surface cultivated in Romania with sunflower crop between 10-12%. The most drought area in Romania is Dobrogea (average 1961-1990: 464 mm rainfall). Climatic change in recent years has accentuated this tendency. The number of hybrids taken into account in our experiment were fifteen in 2018 and twenty in 2020. Genesis has been planted in two periods of the time in 2020. When the planting was delayed the yield was decreased by 303 kg/ha. The aim of this study was: (i) the behaviour of the hybrids in the unbeliveble dry conditions, (ii) to see the yield and the behaviour of sunflower hybrids to the attack of main pathogens - Sclerotinia sclerotiorum, Phomposis helianthi, Orobanche cumana, (iii) how the planting date influenced the yield, (iv) the importance of the pesticides used and (v)economical data.
