Separation of sitosterol, β ecdysone, vitamin B_ (?), Pyridoxine, indoleacetic acid and so on. Crops sprayed with silkworm manure, accelerated photosynthesis, leaf thickening, dark green leaves, shiny, vigorous growth, yield significant. According to the results of multi-year pilot tests in Guangdong, Zhejiang, Henan and Hebei provinces, it is possible to increase the yield of crops such as rice, wheat, corn and cotton by about 10%
