摘要
采用五因素二次通用旋转组合设计试验方法,研究了基本苗及氮、磷、钾、钙施用量五项主要栽培措施对南方水田春花生产量及效益的影响。通过产量及效益数学模型的优化与解析,以明确影响南方水田春花生产量及效益的关键因子和实现高产高效优化栽培的综合农艺措施。结果表明,在5个因素中,对花生产量的影响为:基本苗>CaO>P2O5>K2O>N;要获得300kg/667m2以上产量和1500元/667m2以上的经济效益,其最佳栽培措施组合是:保持基本苗1.75～1.83万/667m2,施纯N:9.93～10.21kg/667m2,P2O5:5.91～6.18kg/667m2,K2O:11.80～12.07kg/667m2,CaO:3.73～4.13kg/667m2。
Relationship between cultivation and yield of spring peanut in paddy fields in south China were studied through experiment. Through an established mathematical model of yield and economic effects,key factors were clarified,and agronomic practices were determined. Results showed that,to achieve a 300kg/ 667m2 yield with 1 500 yuan/667m2,the optimum practices were applying fertilizers of 9. 93 ～ 10. 24kg/ 667m2 nitrogen,5. 91 ～ 6. 18kg/667m2 P2O5,5. 80 ～ 6. 07kg/ 667m2 K2O and 3. 73 ～ 4. 13kg 667m2 CaO under primary seedling density of 1. 75 ～ 1. 83 × 104 plants/667m2.
