摘　　要：采用L16（4^4x2^3）正交设计方法,对秋季大棚豇豆栽培中5个主要栽培因子,即播种时间、播种密度（株距）、每穴点籽数、追肥方式、底肥种类进行了筛选.试验结果表明：施用农家肥作为底肥,播种时间控制在8月1日左右,株距20～25 cm,每穴点籽2～3粒,追施硝酸钾与尿素混合肥的栽培因子组合为适合秋季大棚豇豆的最佳组合.在上述6种栽培因子中,播种时间对产量的影响最大.Using L16 （44x23） orthogonal design method, the autumn big awning eowpea cultivation in six main cultivation factors, namely the sowing seeds time, the thickness of sowing （distance between plants）, each hole dibble seeding number, the topdressing mode, the base fertilizer type has been carried on screening. The results indicated that the farm manure for the base fertilizer, the sowing seeds timing needed control about August 1, distance between plants 20-25 cm, each hole dibble seeding 2-3 grain, the potassium nitrate and the urea mixes cultivation factor combination was the optimal fit to suit the autumn big awning cowpea. In the six kinds of cultural factors, the sowing time was the greatest impact on yield. This study provided a basis for improving the autumn cowpea yield.
