摘　　要：以桃苗为试验材料,采用土壤检测和测量桃苗生长的方法,研究了石灰氮对老桃园土壤和再植桃苗生长的影响。结果表明:石灰氮能减少细菌和真菌数量,但能增加放线菌数量,其中石灰氮60kg/667m^2处理的放线菌增幅最大,石灰氮60、20kg/667m^2的全氮增幅最大,石灰氮60kg/667m^2的有机质增幅最大,石灰氮40kg/667m~^(2+)豆饼100kg/667m^2能同时促进桃苗主干和主枝的生长,因此建议被优先采用。Taking replanted peach seedling as materials,the methods were used to soil testing and measuring the peach seedling growth, the effects of lime nitrogen on the old orchard soil and the replanted peach seedling growth were studied. The results showed that lime nitrogen could decrease the number of bacteria and fungi,but could increase the number of actinomycetes. Lime nitrogen 60 kg/667m2 could significantly increase the number of actinomycetes. The content of total N was increased the most obviously under the treatments of lime nitrogen 60 kg/667m2 and 20 kg/667m2. Lime nitrogen 60 kg/667m2 could increase the content of organic matter the most obviously. The trunks and branches grew the best under the treatment of lime nitrogen 40 kg/667m2 and soybean cake feriilizer 100 kg/667m2, which was advised to be adopted firstly.
