播种量和摘苔高度对优质油菜菜油两用栽培效益的影响

The Effect of the Seeding Rate and Pinching Altitude on the Good Rape Cultivation Benefit for Vegetable and Oil-seed Utilization

研究了播种量和摘苔高度对油菜菜苔、菜籽产量及经济效益的影响。结果表明：在稻田免耕直播条件下，播种密度为2．01kg／hm^2，在苔高为30～35cm时摘苔20cm处理的菜苔产量及经济效益最高，菜籽产量最高。

The effect of seeding rate and pinching altitude on rape vegetable stem, vegetable seed output and economic effect were studied. Result showed that on the rice field zero tillage live broadcast condition, sowing seeds was 2. 01 kg/hm^2 and extracting moss 20 cm treatment whose altitude were 30 to 35 cm, vegetable stem output and economic effect was maximal. Vegetable seed output was also maximal.
