摘要 采用五因素二次正交旋转组合设计试验方法,在高肥地对优良小麦新品种临麦2号的主要栽培措施基施纯N量、追施纯N量、P2O5、K2O及基本苗等与小麦产量间的量化关系进行系统研究,通过对建立的产量数学模型的优化与解析,明确了影响高肥地小麦产量的关键因子及实现高产高效优化栽培的综合农艺措施。结果表明,该五因素与其密切相关,增施氮磷肥是实现临麦2号优化栽培的关键,增施磷肥更益于氮肥肥效的发挥,实现优质小麦新品种临麦2号高产高效优化栽培的综合农艺措施是:每公顷基本苗181.8万 ̄229.2万,基施纯氮量121.95 ̄141.3kg,P2O5195kg,K2O33.75 ̄60.75kg,小麦起身期结合浇水追施纯氮71.7 ̄83.7kg。 The study on the interrelationships among the 5 factors of cultivating measurements (base N-fertilizer, supplementary N-fertilizer, P-fertilizer, K-fertilizer, seeding density) and output in winter wheat Lin-Mai 2 by applying the design of perpendicularity rotational combination in High Productivity Field. The results showed that The yield mathematical model establish by means of adjusting optimization together with analysis, Defining the key divisors and synthetical agronomy measurements that the winter wheat yields of Lin-Mai 2 to growing that high production high efficiency optimizes, good means forms a complete system in the interest of the improved variety in High Productivity Field. The results showed that applying more N-fertilizer and P-fertilizer were the key measurements in the So-called optimum cultivation of winter wheat Lin-Mai 2. It also showed that more P-fertilizer applied made N-fertilizer more effective. The optimum cultivation measurements of winter wheat Lin-Mai 2 for high output high economic benefit were fundamental seeding 181.8 to 229.2 ten thousand per hm2, base N-fertilizer 121.95 to 141.3 kg/hm2, P-fertilizer 195 kg/hm2, K-fertilizer 33.75 to 60.75 kg/hm2 and chase N-fertilizer 71.7 to 83.7kg/hm2 in leave stage.
