甘蔗滤泥有机—无机复混肥对甘蔗的肥效研究

Fertilizer Effect of Sugarcane Filter Mud Organic-Inorganic Compound Fertilizer on Sugarcane

为探索甘蔗滤泥有机—无机复混肥对甘蔗的肥效,设置不施肥、复合肥(15-15-15)、滤泥有机—无机复混肥(12-7-10)共3个施肥处理,研究了滤泥有机—无机复混肥对甘蔗产量、品质与经济效益的影响.结果表明:与复合肥处理相比,施用滤泥有机—无机复混肥提高了土壤肥力,土壤速效氮、有效磷、速效钾与有机质含量分别提高了21.84%、14.17%、42.48%和17.54%;显著提高了甘蔗有效茎数,并极显著提高了甘蔗产量、销售收入和纯收入,增幅分别达25.61%、25.61%和30.82%.滤泥有机—无机复混肥一次性基施与施用复合肥相比,提高了土壤肥力,显著促进了甘蔗生长和产量、效益的提高,值得推广.

To explore the fertilizer effectof sugarcane filter mud organic-inorganic compound fertilizer,three different fertilizations including no-fertilizer,compound fertilizer(15-15-15),sugarcane filter mud organic-inorganic compound fertilizer were applied into sugarcane.The results showed that:compared with compound fertilizer treatment,available N,available P,available K and organic matter in the soils which were dealt with sugarcane filter mud organic-inorganic compound fertilizer treatment increased respectively by 21.84%,14.17%,42.48%and 17.54%.The number of effective stem of sugarcane,sugarcane yield,sales revenue and net income significantly increased by 25.61%,25.61%and 30.82%.The research indicated that the application of filter mud organic-inorganic compound fertilizer for only once improved greatly the soil fertility,growth and yield of sugarcane as well as profit,which is worth popularizing.
