摘要(Abstract):

【目的】研究不同施肥量对洞庭湖区大棚苦瓜生长和产量的影响。【方法】采用肥料效应函数法,总结了苦瓜产量与施肥量的肥料效应方程。【结果】在本试验地力条件下,苦瓜最高产量下的N、P_2O_5、K_2O施量分别为879.38、277.73、1 157.10 kg/hm~2;苦瓜最佳效益产量下的N、P_2O_5、K_2O施量分别为358.65、113.25、471.90 kg/hm~2。【结论】综合考虑产量和效益,N、P_2O_5、K_2O的推荐施量分别为358.65、113.25、471.90 kg/hm~2。
【Objective】Study the effects of different fertilizer amount on the growth and yield of balsam pear in greenhouse in Dongting Lake district.【Method】The method of fertilizer effect was used in this paper, and the fertilizer response equation of yield and fertilizer amount in balsam pear was summarized.【Result】Under the ground conditions of this experiment, the fertilizing applications of N, P_2O_5, K_2O were 879.38, 277.73, 1 157.10 kg/hm~2 when gaining the highest yield of balsam pear. The fertilizing applications of N, P_2O_5, K_2O were 358.65,113.25, 471.90 kg/hm~2 when obtaining the best benefit of balsam pear.【Conclusion】Considering the yield and benefit, it is commended that the fertilizing applications of N, P_2O_5, K_2O were 358.65, 113.25, 471.90 kg/hm~2 when obtaining the best benefit of balsam pear.
