夏秋季松花菜在萧山区种植面积较大,而种子市场上松花菜品种较多,品种表现不一,早花、小花、毛花、畸形花等现象严重影响了松花菜的产量和质量,为此对2017年筛选试验表现较好的秋玉70天松花菜品种进行了适宜播期及密度筛选试验,同时引进了8个品种与常规品种长胜65天F1进行比较以筛选更多优良品种。试验结果表明:秋玉70天松花菜在7月下旬播种,表现为单球质量高、黑斑病发病率低、产量高,以667m2种植2200株为宜,单球质量高,虽然发病率略高,但不影响产量。品种筛选试验中明珠65天花球洁白、球形美观、发病率低、产量高,有示范推广价值。 相似文献

运用南京蔬菜工厂化育苗中心先进的仪器设备,经精心设计后开展试验研究,旨在探索出不同基质含水量与秋播花椰菜工厂化育苗质量间的关系。将秋季花椰菜育苗划分为播种发茅期、子叶期、1叶1心期、2~5叶期、4~5叶期5个生长阶段,在各阶段均设定4个不同的基质水分处理值进行观测比较分析。试验结果表明:秋季花椰菜育苗5个生长阶段的最佳基质含水量依次为基质最大持水量的85%、65%、65%、75%和75%;另可提供秋播花椰菜优质种苗相应标准参考值为:苗龄4~5叶,株高7.47cm,茎粗3.64mm,最大节间距o.78cm,最大叶形指数1.44。 相似文献

Crosses were made in all possible combinations, between winter cauliflower varieties Tinribs and Cambridge Dwarf April, summer cauliflower variety Cambridge 5 and autumn cauliflower variety Majestic. When sown at their normal times these types mature in December, March, June, and September respectively. Data on the maturity periods for parents and Fi and F2 progenies were obtained in the form of accumulated day-degrees.When all parents and progenies were sown at a date near to the normal sowing date for autumn and winter cauliflowers, the F, and F2 generations showed a continuous range in maturity periods between those of the parents and, although the F2 range was generally greater than that of its corresponding Fi, it did not exceed the parental extremes. When the sowing date was near that for summer cauliflowers, the Fi and F2 progenies of crosses which had Cambridge 5 as one parent matured almost as early as Cambridge 5, and the range of maturity was greatly restricted.The annual habit of the summer and autumn types was considered to be partially dominant to the biennial habit of the winter types, and time of maturity was considered to be under polygenic control.Possible improvement of the autumn cauliflower type by making crosses between summer and winter cauliflowers is discussed. 相似文献

In growth chambers the effect of temperature (12–27°C) on the growth and development of cauliflower cultivars of temperate and tropical climates, as well as of broccoli cultivars, was tested. No difference was found between the cultivars as regards dry matter production and curd growth, but a difference was found in the time of curd initiation. The early cauliflower ‘Aristokrat’ does not form lateral shoots or floral buds before elongation of the inflorescence at any temperature level. This always occurs in broccoli cultivars. The tropical cauliflowers have an intermediate position. At low temperatures (12–17°C) only 12–14 leaves are formed. Many lateral shoots are initiated and a broccoli-like curd with fertile flowers is developed. At high temperatures (22–27°C) the same cultivars produce a considerably higher leaf weight, less lateral shoots are initiated, and a cauliflower-like curd without floral buds is formed. 相似文献

为了探索有效监测和防控甜菜夜蛾的产品,结合性信息素在甜菜夜蛾监测和防控中的应用,利用性诱捕技术监测秋茬露地花椰菜田甜菜夜蛾发生规律,对比甜菜夜蛾性诱捕技术和信息素智能监测系统的监测情况、甜菜夜蛾迷向丝的应用效果和不同诱捕器诱芯载体的效果等。结果表明:2017—2019年秋茬露地花椰菜田甜菜夜蛾发生的高峰期为秋茬露地花椰菜定植到结球初期;信息素智能监测系统较人工调查性诱捕器诱蛾量更加准确、高效;甜菜夜蛾迷向应用的迷向率达100%;甜菜夜蛾不同载体诱芯中聚乙烯管材质较橡皮头材质诱集效果更好,单日诱蛾量高,诱蛾谱更清晰。 相似文献

为了探讨春萝卜在武汉地区秋冬季保护地栽培,满足春节期间需求的可能性,选择了20个来自韩国的春萝卜进行品比试验。通过对不同萝卜品种地上部性状、产品器官性状、产品产量以及品质、叶片数与产量的关系进行分析。结果表明,这些萝卜品种在秋冬季保护地栽培基本上生长良好。特别是东洋雪王春、YR新春白玉、特新白玉春、新白玉春A、白玉美5个品种的品质好,产量高,属于优良品种,值得大力推广。 相似文献
