采用正交回归旋转组合设计，对吉８９－４５新品系栽培上四个主要可控因素进行了研究，结果表明：（１）吉８９—４５新品种确实早熟、高产，其平均产量效应为每公顷８６４０．２５公斤，若栽培技术得当，公顷产量最高可达１１１８３．９公斤．（２）主要栽培因素对吉８９—４５产量影响大小的顺序是：施氮量＞插秧苗数＞穗肥所占比例＞插秧方式，尤其是施氮量，对吉８９—４５的产量起决定性作用。（３）预测吉８９－４１５公顷产量在９０００公斤以上时，主要栽培因素，应采用的数量为，施氮量每公顷２１５．６～２３０．６公斤；穗肥比例２２．９％～２６．０％；插秧方式３０×１５．９ｃｍ～３０×１７．２ｃｍ。每穴插秧苗数４．７～５．５个。
The results showed that: (1) Ji 89-45 was indeed precocious and high-yielding, and its average yield effect was Hectare 8640.25 kilograms, if cultivated properly, hectare yield up to 11,183.9 kilograms. (2) The order of the major cultural factors affecting the yield of Ji 89-45 is: the amount of nitrogen application> the number of inoculated seedlings> the proportion of spike fertilizer> the transplanting method, especially the nitrogen application rate, is decisive for the yield of Kat 89-45 effect. (3) When the output of Kyrgyzstan 89-415 hectares is above 9,000 kg, the main cultivation factors should be adopted. The amount of nitrogen applied should be 215.6-230.6 kg per hectare and that of the panicle is 22.9% -26. 0%; Transplanting method 30 × 15.9cm ~ 30 × 17.2cm. Seedlings per hole number of 4.7 to 5.5.
