摘要
通过采用L9（33）的正交设计，得出播期对65002的影响最大，氦素水平次之，密度的影响最小。65002在合肥地区作一季中稻种植，以4月20日左右播种，施纯氦262．5kg／hm2，穴数在22．5～30万穴／hm2之间为宜。
The result indicated that the eeffect of sowing date on rice combination-6502 was largest,the the amount of nitrogen fertilizer,second;transplanting density,lowest through orthogonal design of three factors and three levels,InHefei,the appropriate planting mode of 65002as medium rice was that sowing dat was about april 20;total amount of sheer nitrogen.262.59kg/hm2,transplanting density;22.50-300seedlings/hm2.
