Researches on the relation of a loaded mechanical energy to the damaged banana maturation and its quality evolution has significance to its storage, but there are few researches at present. This paper studied on the effect of the loaded energy on banana to its internal maturation substance evolution and stored quality with time, including the change of maximum impact stress, re-enduring impact energy. The results showed there existed a significant correlation between energy transformation and increment of maturity substance in the damaged banana. Also, there existed a significant association between energy transformation and increment of maturity substance in the damaged banana in its storage time, and appeared a trends that the mechanical energy being transferred into fruit internal energy increased its maturity substance and decreased its stored quality, but individual maturity difference had less effect. Thus, decreasing the energy and the substance transformation in damage area are the important means of extending the physiology life of fruits, which is an urgent problem to be solved in their field of processing and storage at present.

A Study on Sustainable Development of Grain Production Coping with Regional Drought in China

By Fengying Xu Zhen Chen Changyou Li Ce Xu Jieyu Lu Yi Ou

The sustainable development of grain production is a necessary condition for Chinese rapid economic development, which is directly related to people's livelihood and national security. This paper analyzed the frequent occurrence causes of regional drought in China, emphatically enumerated the North-South imbalance of precipitation distribution in time and space, the excessive tillage and grazing and vegetation damage, the hydro-agricultural infrastructure aging and the rapid urbanization diverted for agricultural water resources, which impact the sustainable development of grain production, then proposed some countermeasures coping with frequently regional drought crisis: strengthen the protection of forest vegetation, the scientific planning of planting structure, and the balance regulation of urban industrial water and grain irrigation water, surface water and ground water and of the water allocation between the administrative region, and solve the discharge of sewage purification and desalination technologies, thus establish an integrated balance system of total supply and regional control of grain irrigation water, so as to continuously perfect the durable and stable supply of grain in China.
