摘要
根据旋转回归田间试验测得的数据，建立以亩产量为目标函数的数学模型。通过模拟选优，筛选出番茄亩产高于３．５千ｋｇ的农艺组合措施为：在亩施底肥猪圈粪２千ｋｇ，尿素２０ｋｇ，过磷酸钙３０ｋｇ，追施磷酸二铵１５ｋｇ的肥力基础上，每亩栽植３．９２～４．３１千株。初花期亩喷１９．９×１０－６～２６．５×１０－６的多效唑液４０ｋｇ，单株留果穗４．９～５．４个。每亩群体总果穗数２．１万左右。
Baswd on the information obtained from field research based on the rotation regression design,the mathematic model aimming at gield per muwas set up. Through simulation and optimization,agronomic combinatorial measures for obtaining 3500kg tomato per mu were established,which include these such as 2000kg pig manure as basal dressing, 20kg urea,30kg Calcium Superphosphate. Based on 15kg ammophos of top dressing,planting density was 3920-4310 plants per mu,spraying amount of 19. 9～26. 5 ppm PP333 was 4. 9～5. 4per plant,the total fruit ears werw about 21000. At the same time, effects of single factor and two factore interaction were analysed.
