本文采用二因子(不同块茎大小和栽培距离)四水平随机区组试验,以农业技术经济的观点,运用模糊线性加权变换这一新的数学分析方法,用于魔芋的栽培研究,改进了日本学者高木升等提出的“综合评分法”。选用每亩种子费用、每亩用工、每亩纯收入、每亩净产量、投入产出比和块茎个体风干物净增重等六项指标,密切考虑生产者经济状况和所要达到的目标,计算出在块茎大小和栽植距离上选择的最佳方案:(1)选用100g重块茎作种,以50×33cm距离进行栽植;(2)如果生产者资本较大,主要希望魔芋块茎个体生长得以充分发挥和获得高额的每亩纯收入,选用250g重块茎作种,以66×50cm距离进行栽植。
In this paper, four-level randomized block experiment with two factors (different tuber size and planting distance) was used to study the cultivation of konjac with the view of agricultural technology and economy, and the new mathematical analysis method of fuzzy linear weighted transformation, which improved Japanese scholars Kobayashi raised the “Comprehensive Grading Act.” Selected per acre seed costs, per acre labor, net income per acre, net output per acre, input-output ratio and tubers net dry weight gain of six indicators, in close consideration of the economic status of producers and the desired goal, calculate The best plan is to choose the tuber size and planting distance: (1) Choose 100g weight tubers for planting with a distance of 50 × 33cm; (2) If the producers have large capital, it is mainly hope that the individual growth of konjac tubers will be sufficient Play and get a high net income per acre, use 250g heavy stems for planting, 66 × 50cm distance planting.
