Abstract:

Through analyzed the function evolvement of straw, the most straw use patterns was return fields at present, which can protect ecological environment in agricultural system. Whereas, with many straw cover soil surfaces, there are many adverse influences, for example, it can baffle Mechanical seeding and improve crop development. Many research indicated that effective microorganisms improving those adverse ecological impacts at some extent. Our experiments also proved that effective microorganisms increased crop yields about 20%, result indicate that effective microorganisms can accelerate crop growth.
