摘　　要：通过大田试验,采用对留高茬自然腐烂免耕秸秆覆盖与不覆盖2种条件下,宽窄行双株、宽窄行单株、等行双株、等行单株4种种植方式郑单958光合产物的生产、积累进行了研究.结果表明:残茬覆盖比不覆盖全生育期平均叶面积系数增加6.402%,单株干物质积累量增加8.569%,在整个生育期平均土壤含水量增加了22.315%.同时得出结论:免耕秸秆覆盖宽窄行双珠种植AB1C1处理方式的产量比正常翻梨不覆盖秸秆等行种植AB2C4处理方式的产量提高16.6%,免耕秸秆覆盖与宽窄行双珠种植技术结合效果最佳.Through field experiment,production and accumulation of photosynthate of Zhengdan958 under two conditions of high stubble mulch and no mulch were conducted in four kinds of cultivation methods.The methods were double plants in wide-narrow row,single plant in wide-narrow row,double plants in equal-distance row,and single plant in equal-distance row.The results showed that： compared with no mulch treatment,with the stubble mulch treatment the average leaf area index of whole growth stage is 6.402 % higher,dry matter accumulation per plant 8.569 % higher,and averagesoil moisture of whole growth stage 22.315 % higher.Some conclusions have been obtained：the yield of no tillage with straw cover and wide narrow row double plants AB1C1 treatment is 16.6% higher than that of normal over the pears covered with straw and other row double plants AB2C4 treatment.The method of combining no tillage with straw cover and the wide-narrow row double plants treatment is the best.
