经田间自然抗病性鉴定 ,主推品种抗性差异极显著 ,北 93 313和北 92 2 8较抗病 .在菌核病常发区 ,大豆垄上双行栽培模式的群体微生态不利于菌核病发生 .实行豆 麦 麦的种植结构有益于控制菌核病 .深翻将使菌核在耕层全层感染 ,92 .73%的菌核分布于 5～ 2 0cm土层中 .耙茬和深松·耙茬使 93.85 %和 95 .0 4%的菌核分布于0～ 10cm土层中 .菌核在 3cm土层下几乎不能萌发 .近 10a试验表明 ,将豆 麦 麦的种植结构与耙 松·耙 翻的耕作模式有机结合 ,可将菌核病控制在 5 %左右 ,为菌核病的可持续控制奠定基础 .
After the field natural resistance identification, the main push varieties resistance difference is extremely significant, North 93 313 and North 92 2 8 is more resistant to disease.In the sclerotinia disease area, soybean ridge double row mode of cultivation of micro-ecology is not conducive to bacteria The occurrence of nuclear disease.The implementation of planting structure of bean and wheat is beneficial to control Sclerotinia sclerotiorum will make the sclerotium full-layer infection in the plow layer, 92.73% of the sclerotia distributed in 5 ~ 20cm soil layer. And subsoiling and stubble stubble distributed 93.85% and 95.04% of the sclerotia in 0 ~ 10cm soil layer.The sclerotia could hardly germinate under the soil layer of 3cm.The test of 10 years showed that planting structure of bean and wheat And rake pine rake turn over tillage mode organism, sclerotinia can be controlled at about 5%, to lay the foundation for the sustainable control of sclerotinia.
