Fertilizer efficiency can be expanded from the following ways:
( 1 ) Let the majority of farmers and friends understand the importance of scientific fertilization, master the techniques of balanced fertilization, formula fertilization, and improve the level of scientific fertilization.
(2) pay attention to soil detection work, and gradually establish a soil index system of fertilization. Promote soil testing and formula fertilization technology, according to the characteristics of the soil in various places, carry out targeted fertilization, to achieve the effect of "fat and no waste" and "should be lack of filling".
　　 ( 3 ) Promote the use of potash fertilizer, promote the absorption of nitrogen, phosphorus and other nutrients by crops, and increase the yield and quality of crops.
( 4 ) Promote straw returning technology and increase the application of organic fertilizer, which is conducive to improving soil organic matter.
( 5 ) Implement rotation and interplanting. Improve the effect of fertilization.
Experts predict that it will take five, ten, or even longer years for semiconductor lighting to replace energy-saving lamps and enter thousands of households. However, it is indistinguishable in our life, and so far, it has been used in many areas.
1. Gifts and crafts market: Semiconductor lighting can be used in toys, gifts, flashlights, Christmas lights and other light industrial products. As the main production base of global light industrial products, my country has a huge market demand for LEDs.
2. Landscape lighting market: including architectural decoration, interior decoration, tourist attraction decoration, etc., which are mainly used for decoration lighting of main buildings, streets, commercial centers, historical sites, bridges, communities, courtyards, lawns, homes, leisure and entertainment occasions, and Commercial lighting integrating decoration and advertising.
3. Automotive market: The automotive market is the fastest-growing market for LED applications. It is mainly used for instigating lights such as dashboards, air-conditioning, and audio in the car and internal browsing lights, as well as the third brake light, tail light, turn signal, etc. outside the car. Side lights, etc.
4. Backlight market: LED as a backlight has been widely used in mobile phones, computers, handheld handheld electronic products, automobile, aircraft dashboards and many other fields.
5. Traffic light market: As red, yellow, and green LEDs have the advantages of high brightness, long life, and power saving, the demand in the traffic signal market has increased significantly.
