红小豆高产栽培数学模型研究
Study on high-yield cultivation mathematical model for red adzuki bean
摘要
Abstract
[Objective]The mathematical model for high-yield cultivation of red adzuki bean was studied to provide references for improving relevant cultivation techniques and measures.[Method]Using quadratic regression orthogonal rotation combination design of five factors,the mathematical models between red adzuki bean yield (y) and sowing time (x1),plant densities (x2),pure N(x3),P2O5(x4) and K2O(x5)were established for simulation-optimization.[Result]The red adzuki bean yield surpassed 1255.09 kg/ha when sowed in late April with density of 116.6-123.4 thousands plants/ha and sprayed with pure N 43.92-50.37 kg/ha,P2O5 57.353-62.998 kg/ha and K2O 28.335-31.665 kg/ha.[Conclusion]Quadratic orthogonal rotation combination design with five factors (sowing time,planting density and NPK rates) was workable for building mathematical model for high-yield cultivation of red adzuki bean.In Wanzhou ecological conditions,red bean production is still in need of additional P fertilizer.关键词
