| Abstract: | 【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. |
