一、国内外研究应用现状 优质、高产、高效是农业生产不断追求的目标,传统农业技术、化学农业技术和生物技术对农业生产力的提高起到了不同的促进作用。化学农业的发展对推动农业生产的发展及提高作物产量起到极大的作用,当前,由于大量施用化肥、农药,致使农作物抗病力减弱,造成土壤板结、有机质下降,同时,对环境造成严重的污 First, the status of research and application at home and abroad The status of high quality, high yield and high efficiency is the constant pursuit of agricultural production goals, traditional agricultural technology, chemical agriculture and biotechnology to improve agricultural productivity played a different role in promoting. The development of chemical agriculture plays an important role in promoting the development of agricultural production and increasing the yield of crops. At present, due to the heavy use of chemical fertilizers and pesticides, the disease resistance of crops is weakened, resulting in soil compaction and organic matter decline, meanwhile, the environment is seriously damaged The pollution
