拱棚辣椒——大球盖菇轮作改良土壤试验

Soil Improvement Experiment about Pepper and Stropharia rugoso-annulata Rotation in Arched Shed

为解决拱棚蔬菜种植连作障碍问题,进行了辣椒—大球盖菇轮作试验。结果表明:通过轮作,土壤有机质含量增加0.41%,pH值提高0.46,容重减少0.06 g/cm3,化肥投入量减少约30%,农药使用量降低约50%;辣椒根腐病发病率减少7.5%,667 m^2产量增加523 kg。综合来看,辣椒与大球盖菇轮作可改良土壤,防控土传病害,提高产量,有利于绿色食品的生产。

In order to solve the problems of continuous cropping obstacle of shed vegetables, the pepper-Stropharia rugoso-annulata rotation test was conducted. The results showed that the content of soil organic matter and pH were increased by 0.41% and 0.46, respectively. Soil bulk density and the application amount of fertilizer and pesticides were decreased by 0.06 g/cm3, 30%, 50%, respectively. Pepper root rot incidence was decreased by 7.5% and the yield was increased by 523 kg per 667 m2. Above all, the rotation mode of pepper-Stropharia rugoso-annulata could improve soil, prevent and control soil-borne diseases and enhance yield, which was conducive to the production of green food.
