本文针对四墩子村三种类型家庭草地农业生产结构优化前后的力能学变化进行了研究,结果表明:三种类型家庭生产结构优化后能量转换率、能量产投比都较各自优化前有所提高;三种类型家庭水田投能较为合理,高投高产。而旱田投能较低,产出较低,需加大投入。
In this paper, according to the study of force-energy change before and after optimization of agricultural production structure of three types of family grassland in Si Dunzi village, the results show that the energy conversion ratio and energy production ratio of three types of family production structure are better than those before optimization Increase; three types of paddy field to cast more reasonable, high-yield high. However, the investment in dry land is lower and the output is lower, and the input needs to be increased.
