Abstract.Because spinach seeds have a hard seed coat structure, if direct sowing is adopted without seed treatment in production and cultivation, it is very easy to cause poor seed emergence, resulting in a certain degree of yield reduction. Studying the germination conditions of spinach seeds under different conditions is of great significance for the quality of spinach seed germination and farmers' sowing and production. In this study, two methods were used to treat spinach seeds and observe their germination. The results show that the two methods are significantly better than the control, indicating … Read more →

Abstract.Pollution in microplastics has become a new focus of current environmental governance and ecological protection. The pollution in microplastics is derived from white pollution. Compared with white pollution, the pollution in microplastics is more harmful to the environment and ecosystem. The main reason is that the particle diameter of microplastics is relatively small, which makes it easier to invade the soil and the sea, and microplastics will release some harmful gases through its own oxidative decomposition, resulting in air pollution. Micro-plastic pollution spreads all over many … Read more →
