萝卜多在秋季栽培,初冬收获,是我国北方地区的主要冬菜之一。为适应出口加工及市场周年供应的需要,近年来,我们从引进耐热性、抗病性强的品种入手,进行萝卜反季节栽培大面积开发研究,经专家测产验收, 50天生夏种萝卜平均亩产量为5312.8kg,最大肉质根重3.2kg,取得了较好的经济与社会效益。 一、品种选择 夏浓早生3号系日本7种菌株式会社生产的一代白萝卜杂交种,耐热性强,生长速度快,产量高,品质优,高抗黄萎病、病毒病、软腐病,宜在连作地及病害多发地栽培。品种比较试验产量最高,平均为5370kg/亩,其次是新入洲（3000kg/亩）,鲁萝卜8号（2790kg/亩）,春萝1号（1690kg/亩）,短叶13（1400kg/亩）。方差分析处理间差异极显著。LSR法多重比较,夏浓早生3号小区产量极显著高于其他品种。新入洲与鲁萝卜8号差异不显著,但二者的产量均极显著高于春萝1号和短叶13,春萝1号和短叶13的产量无显著差异。由此看出,夏浓早生3号为萝卜反季节栽培的优良品种。
More radish cultivation in the fall, early winter harvest, is one of the major winter vegetables in northern China. In order to meet the needs of export processing and annual market supply, in recent years, we started with the introduction of heat-resistant and disease-resistant varieties and conducted large-scale research and development on off-season cultivation of radish. The average yield of 5312.8 kg per mu, the maximum fleshy root weight 3.2kg, and achieved good economic and social benefits. First, the choice of varieties Xiaonong early 3 Department of Japan 7 kinds of strains of white radish hybrid production company, heat resistance, fast growth, high yield, excellent quality, high resistance to Verticillium wilt, viral disease, soft rot Disease, should be cultivated in continuous cropland and diseases. The highest yield of the varieties tested was 5370kg / mu, followed by Xinruizhou (3000kg / mu), Luoru 8 (2790kg / mu), Chunrong 1 (1690kg / mu) . Analysis of variance between the difference was significant. Multiple comparisons by LSR showed that the yield of Xia Nong Zao Sheng 3 was significantly higher than that of other varieties. There was no significant difference between Xinjian Island and Luoruobu 8, but the yield of the two cultivars was significantly higher than that of Chuanluo 1 and the short leaf 13, but there was no significant difference between the two. From this we can see, Xia Nong early on the 3rd for the radish season cultivation of fine varieties.
