一、品种选择根据大连市几年来的栽培实践证明,选用地方良种是确保丰产丰收的基础。因此,应选用地方良种为主栽品种,土壤肥力高,栽培管理技术水平高的单位,可辅以山东或其它地区的高产优质良种。目前较好的品种有:小根.中晚熟种,生育期90天左右,抗病性较强,质量好,耐贮藏。连丰.中熟种,生育期85天左右。抗病性较强,对肥水要求不严格,质量较好,较耐贮藏。“80—14”.中晚熟种,生育期90天左右。抗病性较强,抱球质量好,较耐贮藏。核桃纹.中熟疏心品种,生育期85—90天。抗病性较强,耐贮藏。早秋一号.中熟种,生育期80—85天。抗病性强,对肥水要求不严格,质量较好,较耐贮藏。
First, the choice of varieties According to the practice of cultivation in Dalian City for years to prove that the selection of local varieties is to ensure good harvest base. Therefore, local varieties should be selected as the main cultivars, with high soil fertility and high cultivation and management techniques, supplemented by high-yield and high-quality varieties in Shandong and other regions. At present, the better varieties are: small roots. In late-maturing species, the growth period of about 90 days, strong resistance, good quality, storage resistance. Even abundance. In mature species, the growth period of about 85 days. Disease resistance is strong, the requirements of fertilizer is not strict, better quality, more resistant to storage. “80-14”.
