Has anyone used the silkworm excrement fertilizer of Guangdong Plant Dragon Company? What's the effect?

I don't know what silkworm excrement fertilizer you are talking about. At present, the company has two silkworm excrement fertilizer products: one is the silkworm excrement bio-organic fertilizer named Shangheli, and the other is the silkworm excrement bio-organic and inorganic compound fertilizer named Wild Silkworm Youdi. Both of them take silkworm excrement as the main raw material, and the core technology is the endophytic high-activity microbial strain separated and purified from silkworm excrement by the company. The difference between them is that the first one is ecological organic fertilizer, which is generally used as base fertilizer; In the second stage, inorganic fertilizers (nitrogen, phosphorus and potassium) are added, which can be used as base fertilizer and topdressing.

These two products are indeed more expensive than other common fertilizers, but the effect is really good. The main functions of these two products are to improve acid soil (this technology has national invention patent) and promote growth (containing biological bacteria, various trace elements and plant growth promoters, etc.). ) and disease prevention (tobacco stems and exclusive microbial agents), so there is no need to use other products in the process of using these two products (individual crops need to supplement a certain fertilizer separately, such as potatoes need to supplement more potassium fertilizer). Therefore, relatively speaking, silkworm rearing ability and wild silkworm excellent soil are cost-effective, and the use cost will not increase too much, saving time and labor, and it is worth buying.

In addition, there are many cases of using these two products in Plant Dragon official website, with the methods and contact information of farmers on them. What's the effect? Just call a few telephone areas and ask, and maybe you can go directly to the scene to see.
