摘要
在辽西半干旱区膜下滴灌条件下,以阜花17号为材料,研究膜下滴灌不同施肥量对花生生理性状及产量的影响.结果表明:与N+PK、N+Ca和PK+Ca3个处理相比,N+PK+Ca处理的叶面积指数、叶绿素含量与干物质积累量均处于较理想的状态,产量达308.3kg/667m2.说明随水追施尿素、KH2PO4并配施Ca(NO3)2,能较好地促进花生中后期的生长,实现节水增产.
Under the conditions of drip irrigation in semiarid region of western Liaoning, with Fuhua 17 as the material,the effect of different fertilizer treatment under mulch drip irrigation on physiological characters and yield of peanut were studied in this paper.The results showed that the leaf area index,chlorophyll content and dry matter accumulation of N＋PK＋Ca treatment all were in an ideal state compared with other treatments,the yield reached 308.3 kg/667m^2.Indicated that mixed using urea,potassium dihydrogen phosphate and calcium nitrate with water can better promote the middle and later growth of peanuts,and realize water saving and increase.
