摘要
为寻求优质烟叶的田间生产减量施肥方法及验证炭醋材料的实际应用效果,以烟草K326为试材,通过一年三点的田间小区试验,研究了炭醋材料、减量施肥对土壤化学养分动态变化的影响。永仁县的结果表明:与常规化肥基础上减量施肥相比,施用炭醋材料减肥对土壤化学养分氮和钾有良好的缓释作用,对磷有活化作用;姚安县和武定县的研究结果表明:与正常施肥配施炭醋材料相比,减量化肥条件下炭醋材料对土壤的养分具有更好的缓释与活化效果,而在减肥(10%~20%)条件下依然能保持其优越性。因此按照炭醋材料减肥的施肥方式或许能有效减少化肥用量。
To seek the method of reducing fertilization in field and verify the practical application effect of themixture of biochar and pyroligneous,three plots experiment on＇Tobacco K326＇was conducted in one year,tostudy the effect of mixture of biochar and pyroligneous,and reducing fertilization on dynamic change of soil.The results of Yongren County showed that：compared with reducing conventional fertilizer,the mixture ofbiochar and pyroligneous under reducing fertilization could improve the sustained-release effect of nitrogenand potassium,and enhance the activity of phosphorus.The results in Yaoan County and Wuding Countyshowed that compared with the normal fertilization with biochar and pyroligneous,the mixture had betterrelease and excitation effect under reducing fertilization,and the advantage was obvious at reducingfertilization 10%-20%.Therefore,the method of reducing fertilization combined with the mixture of biocharand pyroligneous may be an effective one to reduce the amount of chemical fertilizer.
