生物质灰土壤调理剂在辣椒生产中的应用效果研究

Study on the Application Effect of Biomass Ash Soil Conditioner in Chili Production

为考察以生物质灰为主要原料的土壤调理剂对辣椒连作酸性土壤理化性状的改良效果,开展了田间小区试验,测定了辣椒的生物学性状、产量以及试验前后土壤的理化性状。结果表明:施用生物质灰土壤调理剂对辣椒生长有较好的促进作用,可降低辣椒植株的得病率,辣椒收获后土壤pH由5.2提高至5.8;在试验条件下,生物质灰土壤调理剂施用量为300 kg/亩(1亩=667 m~2)的处理效果最好,辣椒产量最高,有较好的经济效益。

In order to investigate the improvement effect of the soil conditioner using biomass ash as the main raw material on the physical and chemical properties of acidic soil under continuous cropping of chili,a field plot experiment is conducted to determine the biological properties and yield of chili,and physical and chemical properties of soil before and after the experiment.The results show that the application of the biomass ash soil conditioner has a good promoting effect on the growth of chili,which can reduce the incidence of disease in chili plants.After harvesting,the soil pH increased from 5.2 to 5.8.Under experimental conditions,the treatment effect of the biomass ash soil conditioner with a dosage of 300 kg/mu(1 mu=667 m~2) is the best,with the highest yield of chili and better economic benefits.
