摘要
研究不同栽培措施对双低油菜菌核病抗耐性的影响。结果表明:播期与前茬作物对双低油菜菌核病的影响达极显著水平,直播密度对双低油菜菌核病的影响达显著水平。适当晚播、水旱轮作、合理密植可有效控制或减少双低油菜菌核病的发生,增强植株的抗病性。合理增施氮肥能提高双低油菜的产量。
Experiments were carried out to study effects of different cultural measures on resistance and tolerance to Scleratinia sclerotiorum in double - low rapeseed. The results showed that the effects of previous crop and sowing date were very significant, the effect of density was significant. Late sowing, crop rotation and applicable density were effective to control and decrease the disease, they could increase resistance of plants. Adequate nitrogen fertilizer could raise the yield of double - low rapeseed.
