摘要
自1983年开始,在研究上采用农业系统工程的原理和方法,集优化、量化、模式化、综合化为一体进行试验。得出了宁夏南部黄土丘陵区旱作春小麦,以播种量、施肥深度、保墒措施、农家肥和氮、磷肥投入等5大可控因子为基础措施的定量、优化、丰产、综合栽培模式。
With integrated optimiration,quantization,formalization and synthesiza- tion,rain-fed spring wheat cultivation model was developed using agriculture system engineering principles and method.For the hilly-gullied region of South Ningxia,sown amount,depth of applying fertilizer,measures of preser- vation of soil moisture,amount of farm manure,N and P fertilizer are the five basic factor of the modle.The results of application of this model showed it is suitable for the research region.
