应用农业系统工程原理和最优D饱和设计方法探讨了超甜玉米种植密度、氮磷钾肥配合施用的高产高效栽培模式，并进行了综合分析．结果表明：在广东省中等土壤肥力条件下，要取得每公顷毛收益大于2．25万元以上的收入，种植密度应该为57637株，纯N、K2O分别为209．3、162．7kg，并配合104.7kg的P2O5．而高产栽培在没有株型紧凑又耐密植的超甜玉米新组合提供于大田生产之前，纯N、K2O和P2O5每公顷不应超过337．5和168．8kg，种植密度也不应超过7．5万株.
The planting density of super-sweet corn and the high-yield and high-efficiency cultivation pattern of NPK fertilizers were discussed with the principles of agricultural system engineering and the optimal D-saturation design method, and the comprehensive analysis was carried out. The results showed that under medium soil fertility conditions in Guangdong Province, the gross income should be more than 22,500 yuan per hectare. The planting density should be 57,637 strains with pure N and K2O of 209.3 and 162.7 kg respectively With 104.7kg of P2O5. However, high-yielding cultivation should not exceed 337.5 and 168.8 kg per hectare of pure N, K2O and P2O5 and no more than 7 planting density before the new combination of super-sweet corn with no plant compactness and close tolerance is provided for field production. 50,000
