[0003] Magnolia magnolia is majestic and majestic, with broad leaves and thick shade, and fragrant flowers like lotus. It is a beautifying tree species, resistant to smoke and wind, and has strong resistance to toxic gases such as sulfur dioxide. It can be used to purify the air and protect the environment. Therefore, in recent years, People have carried out a large amount of researches on the cultivation fertilizer of Magnolia Magnolia, because chemical fertilizers are generally used to fertilize Magnolia Magnolia overwintering at present, the fertilizer efficiency is low, and the nutrition is single, so that the growth of Magnolia Magnolia is slow, the planting cycle is long, and it will cause hardening of the planting soil, and the planting soil will be hardened. Magnolia has a low survival rate
