Problems solved by technology

At present, Jiangyongxiang pomelo mainly uses conventional 45% nitrosulfur-based compound fertilizers, and does not pay attention to the application of organic fertilizers and micro-fertilizers. There are not many farmers who use special fertilizers or organic-inorganic compound fertilizers. Fertilization methods are unscientific and irregular, resulting in The output of agricultural products and the taste of fruits cannot be greatly improved

At present, the brand of Xiangyu is formed by the unique local soil and climate, and the acidification and hardening of the soil are gradually aggravated by the application of inorganic and conventional chemical fertilizers year after year. If things go on like this, Jiangyong’s brand effect will be difficult to sustain, and farmers’ income will also be reduced. Difficult to increase
