夏秋松花菜播期、密度及品种筛选试验

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。

Screening Test on Sowing Date, Density and Cultivars of Loose-curd Caulifl ower in Summer and Autumn

Abstract: In summer and autumn, loose-curd cauliflower has a large planting area in Xiaoshan district, and there are many cultivars of loose-curd cauliflower on the seed market. The phenomenons of early flower, small flower, wool flower and deformed flower affected seriously the yield and quality of loosecurd cauliflower. Therefore, the suitable sowing date and density screening test of cultivar ''Qiuyu 70-day'' with good performance in the screening test of 2017 was carried out. At the same time, 8 cultivars were introduced and compared with the conventional cultivar ''Changsheng 65-day F1'' to screen more excellent cultivar. The results showed that ''Qiuyu 70-day'' loose-curd cauliflower sown in late July showed high quality of single bulb, low incidence of black spot and high yield. It was suitable to plant 2 200 plants per 667 m2. The weight of single bulb was high. Although the incidence was slightly high, it did not affect the yield. The head trait of ''Mingzhu 65-day'' was white, beautiful, with low incidence and high yield, which was worthy of demonstration and popularization.
