采用五元二次正交回归旋转组合设计 ,通过田间试验 ,分析了旱地冬小麦产量、籽粒蛋白质含量、经济收益等目标性状与播期、密度、农家肥施用量、施氮量、施磷量等栽培因素之间的关系 ,建立了数学模型。通过计算机寻优 ,得出了一套高产优质高效栽培优化方案。在试验地的气候和生产条件下 ,冬小麦适期早播是关键 ,合理密植、增施农家肥、氮磷肥配合施用可以达到高产优质高效的目的
The quadratic quadratic regressive rotation combination design was adopted. Field experiments were conducted to analyze the effects of winter wheat yield, grain protein content, economic benefits and other characteristics and sowing dates, planting density, fertilizer application rate, nitrogen application rate and phosphorus application rate Cultivated factors of the relationship between the establishment of a mathematical model. Through computer optimization, a set of high yield, high quality and efficient cultivation optimization program was obtained. In the experimental climate and production conditions, early winter wheat sowing is the key to proper and close planting, increasing manure, with the application of nitrogen and phosphorus can achieve the purpose of high yield, high quality and high efficiency
