采用正交回归旋转组合设计方法 ,对吉林省优质晚熟品种吉粳 6 6在栽培上的 5个主要可控因子进行了研究。结果表明 :①吉粳 6 6新品种高产、稳产 ,平均产量效应为公顷 8150 7kg ,若栽培技术得当 ,公顷产量最高可达 992 1 1kg ;②主要栽培措施对吉粳 6 6产量作用大小的顺序为 :施氮量 >插秧方式 >施磷量 >插秧期 >施钾量 ,特别是施氮量对产量起着决定性作用 ;③预测吉粳 6 6公顷产量达到 90 0 0kg以上时 ,主要栽培措施应采用的数量为 :插秧期在 5月 2 2～ 2 4日 ,插秧方式以 30 0cm× (13 4～ 14 4 )cm ,施氮量每公顷 2 0 2 6～ 2 10 6kg ,磷肥 (磷酸二铵 )每公顷 2 50 0～ 2 6 2 9kg ,钾肥 (硫酸钾 )每公顷 85 2～ 10 5 0kg。
The orthogonal regressive rotation combination design method was used to study the five main controllable factors on the cultivation of high quality late maturing varieties Jilin 6 6 in Jilin Province. The results showed that: ①Jijing 6 6 new varieties of high yield, stable yield, the average yield effect for the hectare 8150 7kg, if properly cultivated, hectare yield up to 992 1 1kg; ② main cultivation measures on the yield of Jijing 6 6 size order The results showed that: the amount of nitrogen application> the method of transplanting> the amount of phosphorus application> the transplanting period> the amount of potassium application, especially the amount of nitrogen application, had a decisive effect on the yield. (3) When the yield of 66 hectares in Jijing reached 90 0 0kg, The number of transplanting should be adopted in the period of transplanting seedlings from May 22 to April 24, with the planting method of 30 0 cm × (134 ~ 144 cm), nitrogen application rate of 226 ~ 2 10 6 kg per hectare, Diammonium) per hectare 2 50 0 ~ 2 6 2 9kg, potassium (potassium sulfate) per hectare 85 2 ~ 105 0kg.
