【摘要】In order to determine the best fertilization amount and fertilization formula of Momordica charantia in Haikou city, the “2+X” field experiment of fertilization effect was carried out on the laterite soil of Dongshan Town, Haikou City in 2019. The results showed that the yield increase effect was obvious and the yield increase rate up to 12.7%. The yield of the optimized fertilization area was 1628.8 kg/667m2, which was 183.3 kg/667m2 higher than that of the conventional fertilization area. The order of the yield from high to low was optimized fertilization area > conventional fertilization area > 130% optimized nitrogen area > 70% optimized nitrogen area > no nitrogen area. The quadratic equation of nitrogen application rate and yield was established by Excel. The optimal N application rate was 15.91 kg/667m2, and the best economic yield was 1532.28 kg/667m2. The results showed that the optimized fertilization scheme was feasible in summer cultivation of M. charantia.
