摘要: 采用“311-A”拟饱和最优回归试验设计,针对影响泰丰优656产量的施氮量、施钾量和栽插密度进行研究,通过计算机模拟了施氮量、施钾量、栽插密度与产量的关系,建立数学模型,拟寻出最佳栽培方案。结果表明,泰丰优656作烟后稻栽培,其适宜栽插密度为21.0万丛/hm2、施氮量(N) 为142.0 kg/hm2、施钾量(K2O) 为137.6 kg/hm2,可获得较高产量8 846.06 kg/hm2。

Abstract: Using the “311-A” quasi saturated optimum regression design,the effects of nitrogen and potassium application amount and planting density on yield of Taifengyou 656 were studied. The best cultivation techniques through computer simulation and mathematical model were made: the appropriate planting density is 210 000 clumps/hm2, nitrogen fertilizer(N) application amount is 142.0 kg/hm2, potassium fertilizer (K2O) application amount is 137.6 kg/hm2.
