In order to better realize the application value of the project and continuously optimize the project, attention must be paid to the restoration project. This paper mainly analyzes from two aspects of secondary pollution and quality control, hoping to provide reference for the future development and progress of environmental supervision of restoration projects.展开更多

At present, the world's power energy is mostly dependent on thermal power generation. However, the polluted dust and gas released from it will directly affect human health and the natural environment, which is contrary to the concept of sustainable development. Under this background, wind energy has attracted the attention of the energy market due to its renewable and pollution-free advantages. Especially under the background of increasingly mature wind power generation technology, the application rate of wind turbines has been gradually increased, effectively easing the pressure on electricity consumption in the market. In this regard, this paper will analyze the principle of wind power generation and the key points of wind power generation technology, aiming at promoting the promotion of economic and social benefits of wind power generation by improving the control degree of wind power application.展开更多

Because of its rich nutrition, sweet taste and rich iron, it is an important fruit to improve human immunity. Because the demand for apples in the market is relatively large, high yield and quality should be considered by growers. When fruit trees are cultivated, the technique of dwarfing and close planting can advance the fruit bearing time of fruit trees and help people to obtain economic benefits. At the same time, it can also make efficient use of the orchard. Therefore, in the cultivation stage, people can use this technology to dwarf the apple trees, effectively control the crown area, increase the single volume and increase the economic benefits. Based on the in-depth analysis of the technical points such as dwarfing dense planting and management, and according to the market demand, the present situation of dwarfing cultivation of fruit trees is analyzed, and the technical points such as scientific land selection, dwarfing rootstocks, density control, crown pruning, water and fertilizer management, orchard clearing and pest prevention are put forward, so as to explore the efficient management technology of apple tree dwarfing culture.展开更多

How to improve the yield and quality of wheat per unit area has become a key issue for many growers. Green wheat planting is an innovation to traditional wheat planting. It is beneficial to improve the yield and quality of wheat per unit area, ensure the green ecological safety of the produced wheat, and better meet the demand of consumers for high-quality food products. In the following, the paper studies the planting technology of green high-quality wheat with high yield.展开更多
