摘　　要：为了解红壤地区有机配施比例对花生生长的影响,通过田间小区试验研究了不同有机配施比例对花生产量、养分积累以及各生育期土壤中有效态养分动态变化的影响。结果表明:①配施一定比例的有机肥能够显著提高花生产量,以配施4 500 kg/hm2发酵猪粪产量最高;②配施有机肥能够提高花生对养分元素的积累;③有机配施措施在保证花生生长前期的养分供应基础上,有效地提升了花生生长后期土壤有效养分的供应水平。The effects of different fertilization structures on peanut＇s yield and nutrient uptake and release of soil nutrients were studied with field plot experiment in red soil region.The results showed that：1） the combined application of organic and chemical fertilizers significantly increased peanut yield; peanut yield was the highest when plus 4 500 kg/hm2 pig manure.2） Nutrient uptake of the combined application of organic and chemical fertilizers was higher than CK treatment.3） The combined application of organic and chemical fertilizers provided enough N,P and K in the earlier growing period of peanut and enhanced soil available nutrient contents in the later growing period.
