油菜新品种大地199“一菜两用”高产高效栽培技术研究

Study on High Yield and High Efficiency Cultivation Technology of New Rape Variety Dadi 199“Double Use of One Dish”

目的:探索油菜新品种大地199"一菜两用"高产高效栽培技术模式,以提高其种植收益,实现其"一种双收"。方法:通过试验研究不同播期对大地199产量的影响,和不同摘苔处理对大地199生育期、主要农艺性状、产量及经济效益的影响。结果:大地199于2016年9月26日、10月6日和10月16日播种的平均产量分别为207.7kg/667m^2、187.8kg/667m^2和149.7kg/667m^2。摘苔留茬高度5~15cm、15~25cm和25~35cm时籽粒产量分别为220.9kg/667m^2、238.9kg/667m^2和203kg/667m^2,对照不摘苔为180.5kg/667m^2。同时,在对应的摘苔留茬高度时纯利润分别增加了1 128.2元/667 m^2、1 104.0元/667m^2和798.9元/667m^2。结论:大地199在六安地区种植直播最适宜播期为9月26日前后;摘苔处理最适宜留茬高度为15~25cm。

Objective:To realize“a kind of double harvest”,we explored the high-yield and high-efficiency cultivation technology model of the new rape variety Dadi 199“double use of one dish”to increase the income.Methods:Influence of different sowing dates on the yield of Dadi 199.Effects of different mowing treatments on the growth period,main agronomic traits,yield and economic benefits of Dadi 199 were analyzed.Results:The average yield were 207.7 kg/667 m 2 on September 26,187.8 kg/667 m 2 on October 6,and 149.7 kg/667 m 2 on October 16.The grain yield of the pickled mulch were 238.9 kg/667 m 2 for the 15-25 cm,220.9 kg/667 m 2 for the 5-15 cm,203 kg/667 m 2 for the 25-35 cm and 180.5 kg/667 m 2 for the control.The net profit increased by 5-15 cm to 1 128.2 yuan/667 m 2,15-25 cm was 1 104.0 yuan/667 m 2,25-30 cm was 798.9 yuan/667 m 2.Conclusion:The most suitable sowing date for Dadi 199 planting in Lu'an area was around September 26th;the most suitable height for picking moss was 15-25 cm.
