1975—1985年在北京和山东滕县应用盆栽和田间试验方式,进行了秸秆盖田与减耕下土壤培肥增产效应的研究.据160次试验结果表明,该措施调控了土壤微生物区系的活性,促进了土壤有机质的积累;土壤蓄水保墒能力的提高,以及养分供应的改善.作物平均增产10.2±4.4%.采用此措施既可省工(2—18.5个/亩)、节能(20%以上),又可保持水土.目前已在山东滕县等处推广应用150余万亩. In 1975-1985, potted and field experiments were conducted in Beijing and Tengxian, Shandong Province to study the effects of straw mulching and reducing soil fertility on yield reduction.According to the results of 160 experiments, this measure regulates soil microbial flora (20-18% / acre), energy saving (20%), energy saving (20-18%), and the improvement of nutrient supply and soil moisture % Above), but also to maintain soil and water .Teng County in Shandong has now been popularized the use of more than 150 acres.
