Abstract:
In order to find out the main cause and prevention situation of continuous cropping obstacle of pepper in Jiangxi Province.In this study, 6 main areas of production of capsicum in Jiangxi Province were investigated.The main measures of common soil diseases and prevention and control in various regional facilities in jiangxi Province were summarized, and the problems found in the investigation were analyzed, and some thoughts and Suggestions were put forward.The results showed that the facilities in Jiangxi Province pepper were different degree of continuous cropping obstacle problems, Jiujiang, Xingan, Gaoan degree of continuous cropping was relatively serious, chili incidence reached more than 42% on average.In Jiangxi Province, the main obstacles to the continuous cropping of pepper were caused by soil diseases, and the general trend was the increase of the number of years of continuous cropping, the aggravation of the disease and the aggravation of the soil.In addition, the correlation analysis of the soil pH and electrical conductivity of the different continuous cropping years of the capsicum showed that the pH of the soil in the continuous cropping pepper was negatively correlated with the continuous cropping years, while the soil conductivity was positively correlated with the continuous cropping years..Based on the investigation of fertilization in 6 regions and the determination of capsicum soil in facility, it was found that the contents of nitrogen, phosphorus and potassium in the soil of continuous cropping pepper were obviously uneven, but the habit of fertilization was unreasonable. The imbalance of soil nutrients was also an important reason for the continuous cropping of pepper in Jiangxi Province.
