１９９５年为摸索白皮、大粒小麦新品种绵阳２５号的高产潜力，按１９９４年该品种田间回归设计试验优选的６６７ｍ２产５００ｋｇ综合栽培模式并结合供试土壤养分化验结果和小麦需肥特点，在一般栽培条件下，着重增加肥料的平衡投入，并改进施肥方法，在６９１．７ｍ２面积上，印证了模式的可行性，每６６７ｍ２产量达５０３．５ｋｇ，籽粒粗蛋白含量１３．４９％，其肥料投入产出比为１：９．６８，６６７ｍ２获纯利９０３．６元，达到了高产、优质、高效的目的，该模式可供该品种在相似生态条件下推广应用。
In 1995, to explore the high yield potential of white wheat and large grain wheat variety Mianyang 25, according to the comprehensive cultivation model of 667m2 and 500kg, which was selected by field regression design and test in 1994, Under normal cultivation conditions, the fertilizer input was increased and fertilization method was improved. On the area of 691.7m2, the feasibility of the model was confirmed. The yield reached 503.5kg per 667m2 and the content of crude protein was 13.49% Input-output ratio of 1: 9.68,667m2 net profit of 903.6 yuan, reaching a high yield, high quality and efficiency of the purpose of the model for the species to promote the use of similar ecological conditions.
