糯玉米“闽糯0018”高山反季节高产栽培技术研究

Study on Reverse-season High-yielding Cultivation Techniques of Waxy Maize "Minnuo 0018" in High Mountain

应用三因素五水平二次正交旋转组合设计方法,研究了糯玉米品种"闽糯0018"在闽东高山反季节栽培中播种期、种植密度和施氮量对产量的影响,建立了相应的数学模型,并优选出产量大于900.43 kg/667m2的农艺措施方案:播种期5月22～26日、种植密度3757～3988株/667m2、氮肥用量16.97～19.86 kg/667m2。

Using the 3-factor-5-level quadratic orthogonal rotational combination design,this paper studied the effects of sowing date,planting density and nitrogen dosage on the yield of waxy maize variety ＂Minnuo 0018＂,which was cultivated in the reverse season in the mountainous area of eastern Fujian,and established the corresponding mathematical model.The optimum comprehensive agronomic measures for high yield over 900.43 kg/667m2 were screened out as follows： sowing date was on May 22th to 26th,planting density was 3757~3988 plants/667m2,and the dosage of nitrogen was 16.97~19.86 kg/667m2.
