钾硅钙微孔矿物肥对花生生产及土壤性状的影响

摘要

通过田间试验，研究了钾硅钙微孔矿物肥在红壤旱地花生上的施用效果，设置常规施肥、常规施肥＋钾硅钙微孔矿物肥600 kg／hm2、常规施肥＋钾硅钙微孔矿物肥900 kg／hm2、常规施肥＋钾硅钙微孔矿物肥1200 kg／hm2等4个处理。结果表明，与常规施肥相比，增施钾硅钙微孔矿物肥改善了花生的农艺性状和经济性状，提高了花生产量，改良酸化土壤。%Field experiments were carried out on red-soil dryland.Four treatments were designed , i.e.conventional fertilization ( CK) , conventional fertilization+600 kg/hm2 microporous potassium-silicon-calcium mineral fertilizer , conventional fertilization+900kg /hm2 microporous potassium-silicon-calcium mineral fertilizer , conventional fertilization+1200 kg/hm2 microporous potassi-um-silicon-calcium mineral fertilizer ,for the study of effects of microporous potassium -silicon-calcium mineral fertilizer on peanut production and soil properties .The results showed that the new fertilizer improved the agronomic and economic traits of peanut , in-creased peanut yield , and improved the acidified soil as compared with CK .
