For a long time, the independence of the two is more prominent than their organic connection. This research has made preliminary considerations from three aspects. First, it concerns infusing the concept of ecology, contemplating and demonstrating space, as well as reducing the incidence of plant diseases and insect pests of urban green land. Second, the arrangement of flowers and trees for the planning and design of urban green land should comply with the biological attributes of flowers and trees to realize the organic unification of biological and scenic attributes of flowers and trees. Third, the planning and design of urban green land should attach importance to the organic unification of biological and scenic attributes of lawn grass seeds and reduce the difficulty of maintaining lawn. This research attempts to reduce the pressure of maintaining urban green land from the beginning, i.e. the planning and design of urban green land. It also tries to reduce the cost of maintenance and management to the realize planning and design goals of urban green land and the sustainability concerning its maintenance and management and arrive at the mutual unification of the planning and design as well as maintenance and management of urban green land.展开更多

The project overcomes the extreme drought, high temperature, gale and dust salt and salt, and many other adverse environmen- tal factors. Adopted the suitable salt improvement measures and management tech- nology, the artificial green has emerged in the sea of death.

Strengthening the management of urban landscaping maintenance can play a certain accelerating role in promoting the construction of an environment-friendly society in our country, and can also play a helping role in establishing the city image and solving the problem of environmental pollution. Therefore, this paper focuses on the analysis of the problems existing in the process of urban landscaping maintenance management, and then puts forward the solutions, hoping to achieve the quality of urban landscaping maintenance management and lay the foundation for the construction of an environment-friendly society.展开更多

The objectives of this study were to determine the optimal storage parameters for different storage times and to find ways to preserve the green skin color of pears. Specifically, we analyzed the effects of the ethylene inhibitor, 1-methylcyclopropene （1-MCP）, combined with low temperature on quality and maintenance of the green color of Korla Xiang pears during storage. We found that 1-MCP and/or low temperature reduced the loss of green color at 20℃ after being removed from cold storage. In addition, 1-MCP significantly inhibited the decline of titratable acid and ascorbic acid but had no significant effect on fruit firmness and total soluble solids. Low temperature with or without 1-MCP inhibited the release of ethylene, inhibited the decline in the stalk preservation index, inhibited the increase in decay rate and weight loss rate during storage, and inhibited the increase in the core browning index after 225 days of storage. Different storage temperatures had different effects on the quality of Korla Xiang pears. Despite inhibiting ethylene release, a storage temperature of-1.5℃ increased the respiration rate. Storage at -1.5℃ caused core browning eady during storage due to chilling injury, whereas at 2℃ core browning occurred late during storage due to senescence. In late storage, 1-MCP had no significant effect on the maintenance of Korla Xiang pear quality at 2℃. Based on these results, we determined the optimal combinations of low temperature and 1-MCP treatment to maintain pear quality while avoiding chilling injury. For different marketing times, the optimal conditions for storage until New Year＇s Day （a storage duration of 90 days） are 2℃ or 1-MCP combined with 2℃. For storage until the Spring Festival （a storage duration of 150 days）, the optimal conditions are 0℃ or 1-MCP combined with 0℃, and for storage until May （a storage duration of 225 days）, the best conditions are 1-MCP combined with -1.5℃.展开更多
