摘　　要：研究了6个不同收获时期覆膜和露地栽培处理对花生产量及构成因素的影响。结果显示,随着收获期的延迟,烂果数、烂果率和落果率的增加速度越来越快,百果质量和百仁质量的增加速度逐步放缓,覆膜处理的产量和出仁率在9月16日收获达到峰值,露地栽培处理的产量和出仁率在9月21日收获达到峰值。5月12日覆膜栽培处理的产量、出仁率、烂果数、烂果率、落果率、百果质量和百仁质量均优于露地栽培。This experiment was conducted to study the effects of six harvest dates on the yield and its components under film mulching and open field condition.The results showed that with the delay of harvest time,the increase speed of rotten fruit number,rotten fruit rate and drop rate of peanut fruit became faster,and the increase speed of 100-pod mass and 100-kernel mass gradually slowed down.The yield and kernel percentage of peanut with film mulching reached the peak on September 16th,the yield and kernel percentage of peanut under open field reached the peak on September 21st.The yield,kernel percentage,rotten fruit number,rotten fruit rate,fruit drop rate,100-pod mass and 100-kernel mass under film mulching were better than those under open field.
