摘 要：
采用二因素试验设计,在大田条件下研究了配施生物有机肥及化肥减量对玉米间作豌豆体系土壤微生物、产量及产量构成的影响.结果表明:有机肥无机肥配施可以显著提高玉米间作豌豆的混合产量.在作物生长过程中,配施有机肥可以显著增加土壤微生物数量.A1B1处理混合产量达到了最高,为13 223kg/hm2,微生物数量高于其他不配施有机肥的处理,但在配施有机肥的处理中微生物活性最低;A2B1处理土壤微生物数量最高,与其他处理相比差异显著,混合产量也达到了10 549kg/hm2,与当地农技部门推荐施肥量A1B2处理相比差异不显著.表明化肥减量15%并配施有机肥是适合河西绿洲灌区玉米间作豌豆的施肥措施.

摘 要：
In order to solve the current situation of food production in the simple application of a large number of chemical fertilizers,use two factor randomized block design method to study the response of soil microorganism and yield of maize/pea intercropping to bio-organic fertilizer and reduced chemical fertilizer.The results showed that the combined application of organic and inorganic fertilizer significantly increased the yield and the number of microbes in pea/maize intercropping system.The mix yield of A1B1 reached the highest,which was 13 223kg/hm2,the number of microbes of A1B1 was more than other no-bio-organic fertilizer treatment,and less than other bio-organic fertilizer.The number of microbes of A2B1 was significantly higher than other treatment,the mix yield of A2B1 reached to 10 549kg/hm2,which was not significantly different with A1B2.The best treatment was A1B2,reduction of 15% chemical fertilizer and combined application of bio-organic.
