不同滴肥条件对花生生理性状与产量的影响

Effect of Different Fertilizer Drip Irrigation on Physiological Traits and Yield of Peanut

在辽西半干旱区膜下滴灌条件下,以阜花17号花生为材料,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,NPKCa区的LAI、叶绿素含量与干物质动态变化均处于较理想的状态,说明随水追施尿素、磷酸二氢钾并配施硝酸钙,能较好地促进花生中后期的生长,最高产量达4 624.5 kg/hm2。

Under the conditions of drip irrigation in semiarid region of western Liaoning,with Fuhua No. 17 for the material,the influence of different fertilizer treatment under mulch drip irrigation on agronomic traits and yield of peanut was studied. The results showed that LAI,chlorophyll content and dynamic change of dry matter of NPKCa treatment were all in an ideal state,it illustrated applying urea,potassium dihydrogen phosphate and potassium nitrate with the water could better promote the growth of peanut in the later stage,the highest yield reached 4 624.5 kg/hm2.
