Drought-resistant seedlings
Actively divert irrigation, and mainly furrow irrigation, supplemented by watering, to keep the soil moist is appropriate. Do not flood irrigation, so as not to cause soil compaction, to prevent the emergence of dead seedlings, dead seedlings.
Topdressing fertilizer
The application of rapeseed stubble fertilizer should be due to seedlings, fat, and time-varying. For rape that grows more prosperous, generally less or less fertilization is applied, and rape that grows weak must be applied. The manure is generally based on compound fertilizers. It should generally be applied one time before mid-February and generally apply 7-10 kilograms of compound fertilizer; for weak seedlings, small seedlings and red seedlings, 2-3 kilograms should be added. Urea. Fertilization should be selected before or after rainy days, or combined with irrigation for top dressing, or applied in sunny evenings. The fertilizer should not be applied to the foliage, and the contact between the fertilizer and soil should be ensured so as to increase the fertilizer utilization and Prevent burning seedlings.
Weeding and thinning
At present, the weeding of live rapeseed is relatively serious. It is suggested that weeding should be carried out for the field where weeding or chemical weeding has not been thoroughly implemented. Can choose special herbicide for rapeseed. In the time of weeding, the choice of application on sunny afternoons is better. For fields with only a small amount of weeds and more basic seedlings in the field, the nested seedlings and crowded seedlings were removed manually in time.
Disease prevention and control
After rape enters spring, as the temperature rises, some of the functional leaves will also age and turn yellow. Therefore, it is necessary to select sunny leaves to remove old yellow diseased leaves and reduce the breeding grounds for disease occurrence. Diseases should be prevented and treated as soon as possible. For rapeseed fields that have been harvested in a drought, it is necessary to actively guide farmers to replant early spring crops such as peas, potatoes, vegetables, and corn.
Highway fog lights
Many highways use traffic lights and fog lights. The products of highways are actually stable and durable. It can`t be said that one product can be used for one year. The highway is a major investment in a national infrastructure project. If each product is only used for one year, it is really too much waste. Therefore, when choosing highway electromechanical products, especially 304 stainless steel fog lamps, 304 stainless steel is used, it is best to choose the best materials. If you do this, you might get a little more money at the beginning, but in the end he will achieve completely different results.
Stainless steel fog lights and traffic lights,
Many expressway electromechanical projects have been noted during the bidding. The lights at the entrance of the expressway must be made of stainless steel and made of primary colors, that is, its color does not need to be sprayed. Why? Because the material of 304 is relatively good, then 304 will not rust. After many years, its color will be as smooth as new. Therefore, this material has a very good quality for the entire highway mechanical and electrical product entrance, passage entrance and exit. Big one system improvement
Iron fog lamp
Are there any traffic lights and fog lights made of iron or plastic? The answer is yes. For many highway electromechanical projects, the owners themselves need very good things, but after bidding, after layer by layer, 316 stainless steel will change. It becomes 304, 304 stainless steel becomes an iron box, and the iron box finally becomes a plastic material. In fact, this is very bad.
What is 304 stainless steel? Stainless steel refers to a kind of stainless steel that is not easy to rust under normal conditions, and its surface is the original color, which means that it is black and white, and looks very high-grade, just like the stainless steel seat you see in an airport. The chair is the same, so the stainless steel is made into stainless steel fog lamps and stainless steel traffic lights, it looks very beautiful, and then after the surface is drawn, it looks even more high-end and high-end.
How many years can 304 stainless steel traffic lights and 304 stainless steel fog lights last? 304 stainless steel fog lights, 304 stainless steel traffic lights, they can basically be used for 5 to 8 years, because why, the shell will not rust, and the components inside will be protected after the shell does not rust. The LED itself is normal. The following can be used for 5~10 years, so the stainless steel material protects the internal components from moisture, and it will not cause damage to the internal components due to rust.
