摘要
[目的]为寻求烟区烟田土壤酸化治理的改良方法。[方法]2010～2012年,湖北省鹤峰县在烟叶生产上共累计推广施用土壤调理剂767 hm2。在烟田酸化地块烟田起垄时,垄沟施750、1 125 kg/hm2土壤调理剂。[结果]在烟田酸化土壤地块施土壤调理剂750～1 125 kg/hm2,能有效推迟烟叶土传病害的发病时间10～15 d,小区试验有效率达95%,大面积示范施用土壤调理剂平均有效率为68.2%。[结论]该研究为烟叶可持续发展提供了参考。
[ Objective ] The research aimed to find the methods to control the soil acidification. [ Method ] Soil conditioners were used wildly in tobacco production about 767 hm2 in Hefeng county of Hubei province. 750- 1 125 2 kg/hm sod conditioner was applied in the filed. [ Result] Soil conditioners could delayed efficiently soil-borne diseases by 10 - 15 days. The effective rate of plot experiments was 95% and the trial and demonstration of soil conditioner reached 68.2%. [ Conclusion] The research provided a reference for the sustainable production of tobacco.
