| 摘 要： | 利用肥料二次回归3414设计,对湛江市甘蔗施氮、磷、钾肥料参数进行研究。结果表明:全肥区比缺氮区、缺磷区及缺钾区分别增产6.33%、8.62%及2.44%,其中以磷肥的增产率为最高。通过三元二次施肥模型计算,得出N、P2O5和K2O的最佳施用量分别为171.3、432.0、0 kg/hm2,收益是40 367.92元/hm2。通过肥料3414试验,能实现主要养分平衡供应,满足甘蔗高产高糖生产需要,达到提高肥料利用率及高产的目的。 |

| Abstract: | In this study,a design of 3414 fertilizer experiment was carried out to calculate the fertilization parameters for sugarcane.The results showed that the yield of the full fertilization treatment increased by 6.33%,8.62% and 2.44% respectively,compared with the treatments of nitrogen-starved,phosphorus-starved and potassium-starved.The effect of phosphorus fertilization was the best among the three elements.Based on the three variable quadratic model regression analysis,the optimal supplying rates of N,P2O5 ... |
