生产成本是评价技术经济效果的综合性指标;是衡量各项技术措施的科学性和使用生产资料合理性的经济指标。小麦生产的经济效果如何,最后都综合反映在小麦单位产品成本上。产量高,成本低,经济效果就好;相反,经济效果就差。(一)产量、投资与成本的关系小麦单位产品成本的高低,决定于单位面积产量和每亩投资费用两个方面。前者除受自身生长发育规律支配外,还受气候因素、土壤因素和人为栽培管理水平的影响,换言以,要获得高产、稳产,首先要有优良品种,再加上适宜的栽培技术措施,在良好的环境下,产量性状才能充分的发挥出来,这三种因素配合得越好,产量越高。后者则是指单位面积上生产
The production cost is a comprehensive index to evaluate the economic effect of technology. It is an economic indicator to measure the scientificity of various technical measures and the rationality of using the means of production. The economic effect of wheat production, the final comprehensive reflection of the cost of wheat per unit of product. High output, low cost, the economic effect is good; on the contrary, poor economic results. (A) the relationship between production, investment and cost The level of product cost per unit of wheat, determined by the yield per unit area and investment costs per acre two aspects. In addition to the former by their own growth and development rules, but also by climate factors, soil factors and artificial cultivation and management of the level of impact, in other words, to obtain high yield and stable production, we must first have good varieties, coupled with appropriate cultivation techniques, In a good environment, yield traits can fully play out the better the three factors, the higher the yield. The latter refers to the production per unit area
