不同播种期对芥菜型油菜产量及品质的影响

Effect of Sowing Date on Yield and Quality of Brassica juncea Czern Coss

通过不同播种期对芥菜型油菜产量和品质的影响试验,结果表明:在当年的4月下旬到5月初播种,油菜植株发病率低,有利于提高油菜的产量和品质;而推迟播种期,由于地温升高,油菜出苗明显加快,但其生长后期遇到高温多雨天气,植株发病率明显升高,严重影响了油菜的产量和品质。因此,在当地适时播种芥菜型油菜是保证丰产增收的措施之一。

The studies on effects of planting dates to yield and quality of B.juncea Czern Coss.Spring rape were conducted.The results showed that mid-April to early May sowing could not only increase the spring rape yield but also improve the quality and induced the incidence of the spring rape.Delayed sowing, the post of growing meet the hot and rainy weather, incidence of spring rape obvious increased,seriously affect the yield and quality.but,because the temperature rise,emergence speed up,Timely sowing in the local is one of the measures to ensure high yield production.
