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请下载后查看，本文暂不支持在线获取查看简介。(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。
Using peach seedlings as experimental material, the effects of lime nitrogen on the growth of old peach soils and the replanting of peach seedlings were studied by soil testing and measuring the growth of peach seedlings. The results showed that lime nitrogen could reduce the number of bacteria and fungi, but increase the number of actinomycetes, of which the actinomycetes with lime nitrogen 60kg / 667m ~ 2 increased most greatly, the nitrogen with 60kg / 667m 2 nitrogen increased most , Lime nitrogen 60kg / 667m ~ 2 the largest increase in organic matter, lime nitrogen 40kg / 667m please download to view, this article does not support online access to view profile. (2+) soybean cake 100kg / 667m ~ 2 can simultaneously promote the growth of main stem and main branch of peach, so it is recommended to be adopted first.
