【摘要】 棉花生产是一个复杂的大系统,为了使其系统输入输出最优化,以便达到高产、优质、低耗、高效益的目的,我们研制了适应于每公顷产1500公斤皮棉的棉花生产管理决策支持系统CPMSS和棉花生长发育动态模拟模型CGSM。目前,CPMSS/CGSM系统可以完成一熟春播棉田的播前决策、生长发育期间的调控决策以及生育后期的估产。更多还原

【Abstract】 CPMSS is a decision-making support program for cotton crop management, and CGSM is a dynamic simulator medel for cotton growth and development under high--yield production conditions. The basic decision-making to manage cotton crop in a country is composed of CPMSS and CGSM. This system have some functions as follows: 1. Making a decisive project as a whole. Ac- cording to the resources of climate, soil and water in the given region, and climatic forecast of the year, an overall decision-making project to manage cotton crop is made, and it includes variety, planting date, row spacing, nitrogen at planting, nitrogen topdressing and application day, DPC and so on. 2. Dynamic adjusting decision-making during the growing period. Ac- cording to crop growing condition and all the measures adopted before, crop developing ten- dency can be determined and crop cultural measures are recommended by the system during the growing period. 3. The system is able to simulate the structure of lint yield and estimate the lint yield of this year in later August. 4. Driving CGSM model, the crop development dur- ing the growing period can be simulated by the system.更多还原
