【摘要】：為黃壤旱地合理施肥與養(yǎng)分綜合管理提供依據(jù),實(shí)現(xiàn)黃壤旱地可持續(xù)利用,以選擇貴州黃壤肥力與肥料長(zhǎng)期定位試驗(yàn)中不施肥(CK)、常量有機(jī)肥(M)、常量有機(jī)肥+常量氮磷鉀肥(MNPK)和常量氮磷鉀肥(NPK)4個(gè)處理,分析貴州黃壤長(zhǎng)期定位施肥18年后的旱地土壤微生物量C和微生物量N。結(jié)果表明:長(zhǎng)期施肥對(duì)土壤中的微生物量C和N均有增加作用,并且影響趨勢(shì)一致,含量依次為M+NPKMNPKCK。與CK相比,各施肥處理均提高了微生物對(duì)有機(jī)碳、全氮的利用率,其中全氮的利用率提高最明顯,M+NPK處理中土壤微生物對(duì)氮利用率最高,約為CK的5倍,其次是M處理,為CK的4.37倍。各處理有機(jī)碳利用率與CK差異較小,其中M處理土壤微生物對(duì)有機(jī)碳利用率最高,其次為M+NPK處理。
[Abstract]:It provides the basis for rational fertilization and integrated nutrient management in yellow soil upland, and realizes the sustainable utilization of yellow soil upland. Four treatments of (CK), constant organic fertilizer (M), constant N P K fertilizer (MNPK) and constant N P K fertilizer (NPK) were selected in the experiment of soil fertility and fertilizer location in Guizhou Province for a long period of time. The results showed that there were four treatments in this experiment: no (CK), constant organic fertilizer (M), constant N P K fertilizer (MNPK) and constant N P K fertilizer (NPK). The microbial biomass C and N of upland soil after 18 years of long-term fertilization in yellow soil of Guizhou Province were analyzed. The results showed that long-term fertilization had an increasing effect on microbial biomass C and N in soil, and the effect trend was the same, and the order of content was M NPKMNPKCK.. Compared with CK, all fertilization treatments increased the utilization efficiency of organic carbon and total nitrogen. The soil microbial utilization efficiency of M NPK treatment was the highest, about 5 times of that of CK, followed by M treatment. It is 4.37 times of CK. There was little difference between the organic carbon utilization efficiency of each treatment and that of CK, in which the soil microorganism of M treatment had the highest organic carbon utilization efficiency, followed by M NPK treatment.
