适合中小型机械化收获的宽行距甘蔗种植研究

甘蔗机械化收获要求合适的种植行距。本文以湛江地区普遍种植的粤糖94-128品种为例,研究在1．0、1．2和1．4m种植行距下新植蔗和第1～2年宿根蔗在大田的表现。结果表明,该品种在湛江遂溪地区适合1．2m和1．4m行距的种植模式。采用1．2m和1．4m行距的甘蔗产量高于采用1．0m行距的产量,1．2m行距下产量略高于1．4m行距下的产量。本文的研究结果对推动甘蔗宽行距在湛江地区种植具有积极作用。     

不加酵母机械化酿制香雪酒的研究

不加酒母（不外加任何酵母）机械化制香雪酒经在实验室和机械化大罐两方面的发酵试验研究,并定期理化测定和检测,结果表明：不加酒母（不外加任何酵母）机械化制香雪酒是可行的,质量有保证,减少了制酒母工序,降低了成本,创新了香雪酒酿制工艺;机械化香雪酒发酵过程中,酵母数量少,作用小,而细菌较多,在其中起重要作用。     

Energy demand forecast for mechanized agriculture in rural India

Though India has done well in agricultural development, the state of Assam in the northeastern region needs special attention for agricultural development to address several socio-economic issues and is a typical example of economically backward rural India. Agricultural development aiming at higher production would require mechanization and supply of sufficient energy is a prerequisite for mechanized agriculture. Rice is the major crop of Assam and the mechanization is at a nascent stage. The energy demand and supply scenarios with reference to some prospective mechanization strategies for rice crop are investigated in this study. Four strategic scenarios of mechanization including a baseline scenario incorporating some proven technologies are designed to assess the energy demands. The result of the analysis indicated that the demand for diesel would increase by more than 200% with an associated decrease in manpower by more than 80% and also 100% reduction of bullock power. The “availability index”, which is the ratio of available human workers to its critical demand, indicated insufficiency of required human workers in almost all agro-climatic zones of Assam justifying the need for mechanization. Economic analysis considering the prevailing rate of input commodities also favors agricultural mechanization in Assam.     

Algorithmization and mechanization of the Cauchy problem associated with the plate equation

This paper develops the algorithm and mechanization of the Cauchy problem associated with the plate equation. The solution is obtained in terms of the initial data on the deflection of the plate and the load term. Thereafter, the algorithmization formulae are used in MAPLE to solve the Cauchy problem automatically.
