摘要
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。
Adopting the orthogonal gyrating-regression disign,4 main elements for cultivation of the new line Ji89-45 wered studied. The result showed: (1)the new line Ji89-45 was earlymaturing, high yield, the arerage yield was 8640. 25kg/ha, and the highest yied was i1183. 9kg/ha..(2)The effect of the main Cultural elements on Ji89-45 was in the order:The amount of applied fertilizer (N)was the most importallt element affecting on the yield, follewed by transplanted sgedlings, proportion of booting fettilizer,way of transplanting seedlings. (3) It is calculated that: when the yield of Ji89-45 is 9000kg/ha per hectare, main clements for cultivation should be the followings: the, amount of appled fertilizer (N ), 215. 6-230. 6kg,per hectare; the proportion of bogting fertilizer:22. 9-26. 0% ; the way of transplanting seedlings:30 ×15. 9cm￣ 30 ×17. 2cm , and with 4. 7--5. 5seedlings Per hill.
