摘要
采用正交回归旋转组合设计方法,对优质超级稻品种吉粳88栽培上5个主要可控因素进行了研究。结果表明:①吉粳88高产稳产,平均产量效应9101.4kg/hm2,若栽培技术得当,最高产量可达11269.1kg/hm2;②主要栽培措施对吉粳88产量作用大小的顺序为:施氮量>插秧方式>施磷量>插秧苗数>施钾量,其中施氮量对产量起着决定性作用;③预测吉粳88产量达到10000kg/hm2以上时,主要栽培措施为:施氮(N)量220.3~228.0kg/hm2、施磷(P2O5)量102.0~111.5kg/hm2、施钾(K2O)量28.5~38.7kg/hm2、插秧方式(行株距)30cm×(13.6~14.8)cm、插秧苗数5.1~5.8苗/穴。
Adopting the orthogonal-gyrating-regress design, 5 factors in the culture of high quality super rice variety ‘Jijing 88' were studied. The results showed that: (1) ‘Jijing 88' could produce high and steady crop, the average yield was 9 101.4 kg/hm^2. If it was properly cultivated, the highest yield of 1 1269.1 kg/hm^2 can be reached.(2) The order of effect of cultural factors on the yield of ‘Jijing 88' was: Nitrogen apphcation〉the way of rice seedling transplant〉Phosphorus application〉number of rice seedling transplanted〉 Potassium application. Among these factors, Nitrogen application is the most important to yield. (3) If the yield of ‘Jijing 88' reaches over 10 000 kg/hm^2, it must be cultivated in such ways as follows: 220-228.0 kg/hm^2 of Nitrogen , 102.0-111.5 kg/hm^2 of Phosphorus and 28.5-38.7 kg/hm^2 of Potassium applied, rice seedling transplanted at density of 30×13.6-14.8 era, 5.1-5.8 seedlings per hold.
