福州地区冬春季不同机播密度对菜心生长及产量的影响
Effects of different machine sowing densities in winter and spring on the growth and yield of flowering Chinese cabbage in Fuzhou
摘要
Abstract
[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.关键词
