摘　　要：【目的】为探讨福州地区冬春季菜心种植的最佳机播密度,提高菜心的商品性及产量。【方法】以‘金品绿珍5号’菜心为供试材料,试验设4个不同机播密度处理,即机播齿轮1格、机播齿轮2格、机播齿轮3格、机播齿轮4格,以人工播种为对照。采收期调查各处理菜心的植物学性状指标、抗病性及产量,分析不同机播密度对菜心生长、病害及产量的影响。【结果】与人工播种相比,机播密度为机播齿轮3格的产量最高,商品性最好,霜霉病发病率较低。其次是机播齿轮2格处理,产量较高,病害较轻达高抗水平,但菜薹较细,商品性略差。【结论】适当密度的机播能提高菜心的产量和质量,且具有明显的增收节支效益。【Objective】In order to explore the best machine sowing density of flowering Chinese cabbage in winter and spring in Fuzhou and improve its marketability and yield.【Method】Taking‘Jinpinlvzhen No.5’as the tested material,four treatments were set up in the experiment,i.e.Machine-sowing gear 1 grid,machine-sowing gear 2 grids,machine-sowing gear 3 grids,machine-sowing gear 4 grids with artificial sowing as CK.Botanical characters,disease resistance and yield of flowering Chinese cabbage in each treatment were investigated during the harvest period.The effects of different machine-sowing densities on the growth and yield of flowering Chinese cabbage were studied.【Result】The results showed that compared with artificial sowing,machine-sowing gear 3 grids had the highest yield,good commodity,and low incidence rate of downy mildew.The second best effect by machine-sowing gear 2 grids had higher yield,less disease and reached high resistance level,but the flowering Chinese cabbage was thinner,and the commodity is less than that under machine-sowing gear 3 grids.【Conclusion】Properly mechanical sowing density can enhance the yield and quality of the flowering Chinese cabbage,and offers significant effects in increasing income and costing expenses.
