摘要
为明确微量元素对甘蔗产量的影响,确定甘蔗产量的最优微肥组合方案,采用四元二次回归正交旋转组合设计,研究铜、锌、硼、钼4种微肥配合施用对甘蔗产量的影响。结果表明:4个参试因子对甘蔗产量的影响顺序是锌肥>钼肥>铜肥>硼肥。频率分析结果显示,甘蔗产量大于93 372.09kg/hm2的施肥组合方案为:铜肥量5.625～7.875 kg/hm2,锌肥量37.5～45.0kg/hm2,硼肥量19.687 5～22.500 0kg/hm2,钼肥量0.60～0.75kg/hm2。从甘蔗最高产量考虑,最优组合方案为硫酸铜7.875kg/hm2,硫酸锌45.0kg/hm2,硼砂22.500 0kg/hm2,钼酸铵0.75kg/hm2;最优组合田间示范验证甘蔗产量为121 275.0kg/hm2,与试验回归模型计算的结果(121 925.47kg/hm2)接近。
In order to explore an optimal composite scheme of trace elements to gain the highest yield of sugarcane,the impact of Cu,Zn,B,Mo on the yield of RCC22 was researched in this paper.The orthogonal combination design of quadratic regression was adopted in this experiment.The result showed that the impact on yield of sugarcane by these four factors ranked as follow：Zn＞Mo＞Cu＞B.The result of frequency analysis showed that the range of the composite scheme of Cu,Zn,B,Mo for optimal cultivation measures for high-yield （＞93372.09 kg/ha） in sugarcane was 5.625-7.875 kg/ha,37.5-45.0 kg/ha,19.6875-22.5000 kg/ha,0.60-0.75 kg/ha,respectively.For the highest yield of sugarcane,the optimal composite scheme for Cu,Zn,B,Mo was 7.875 kg/ha,45.0 kg/ha,22.5000 kg/ha,0.75 kg/ha,respectively.The yield of the sugarcane planted in the field with this optimal composite scheme was 121275.0 kg/ha,which was similar to the result from the test regression model （121925.47 kg/ha）.
