不同种植模式下夏玉米生长发育及产量的试验研究

Experimental Study on Growth and Yield of Summer Maize under Different Planting Patterns

研究了不同栽培方式对夏玉米叶面积指数、地上干物质积累及产量的影响。结果表明,垄作栽培夏玉米与传统平作栽培相比,全生育期叶面积指数垄作均比传统平作大,最大差值为0.43,梯形垄作栽培的夏玉米叶面积指数高于V形垄,最大差值为0.23。地上干物质积累量及产量均高于传统平作,而梯形垄作种植模式优于V形垄作栽培的夏玉米,梯形垄作种植夏玉米适宜在豫西地区广泛推广。

Studied the different cultivation way to the summer maize leaf area index,ground to do the material accumulation and the output influence.The result indicated that the ridge culture cultivation summer maize and the tradition makes the cultivation to compare evenly,the entire period of duration leaf area index ridge culture is evener than the tradition does increases,the biggest differential value is 0.43,the trapezoidal ridge culture cultivation＇s summer maize leaf area index is higher than V-shape ridge,the biggest differential value is 0.23.Ground does the material accumulation quantity and the output is higher than the tradition to do evenly,but the trapezoidal ridge culture planter pattern surpasses V-shape ridge culture cultivation the summer maize,trapezoidal ridge culture planter summer maize being suitable widely promotes in western Henan province.
