玉米与辣椒间作关键栽培技术研究

The High-efficiency Cultivation Techniques of Intercropping Corn with Pepper

在玉米与辣椒间作复合体系中,选择玉米密度、辣椒密度、玉米辣椒剪叶剪枝和微肥(硼肥与锌肥)为处理因素,采用4因素3水平L9(34)正交设计方法,开展了主要栽培措施对玉米和辣椒产量影响的试验研究,建立并解析了数学模型,通过计算机模拟寻优,筛选出了优化的栽培方案,即A1B3C2D2[玉米密度1 600(60 cm×35 cm)株/667 m2,辣椒密度3100(50 cm×25 cm)窝/667 m2,辣椒剪枝,喷0.2%硫酸锌溶液]。

Four factors and three level L9（34） orthogonal design,including maize planting density,hot pepper planting density,pruning branches of hot pepper and leaves of maize and trace element fertilizer（boron and zinc）,were used to elucidate the effects of main cultivation measures on the yield of corn intercropped with hot pepper in the present investigation.A mathematical model had been established,and the optimized cultivation program,which selected via computer simulation,was A1B3C2D2,suggesting a density of 1600 plants / 667m2（60cm × 35cm） for maize and 3100 plants / 667m2（50cm×25cm） for pepper.Additionally,pruning of pepper branches,and spraying of 0.2% zinc sulfate solution were also carried out.
