Fertilization at Seedling Stage In order to grow seedlings with thick stems, short internodes, and well-developed root systems, bed soil must be fertile. In a bed of 11.3 square meters, 200 kg of organic fertilizer is applied, 0.5 kg of superphosphate and 0.5 kg of potassium sulfate, and the bed soil is mixed with the fertilizer. Can also be applied manure mixed fertilizer 100-150 kg and nitrogen, phosphorus, potassium compound fertilizer 1 kg.
Basal fat eggplant fertilizer and fertilizer, must be re-base fertilizer. Before spreading the ground, spread 5000-7000 kg of organic fertilizer per acre, apply 15 kg of superphosphate and 10 kg of potassium sulfate, and then plow till the soil is used for soil preparation; 3000-5000 kg of organic fertilizer may be applied per acre before turning to the ground. Fertilizer, and then do hoeing or hoeing, transplanting and then application or ditch 1500 kg of organic fertilizer and 25-50 kg of nitrogen, phosphorus, potassium compound fertilizer.
During the lifetime of eggplant, it takes a long time to grow fertilizer. The absorption of nutrients by eggplant rapidly increases after the flowering period. Therefore, the key period of topdressing is the harvest of “door-to-door winks†to “four-door fightsâ€. During this time, it can be topdressed once every 10 days, each time after the application of ammonium sulfate 15-20 kilograms or urea 7.5-10 kilograms, of course, it is best to follow the application of decomposed human excrement 500-600 kilograms. The fertilization method can be applied by ditching, acupuncture or flushing with water.
Precautions During the later growth period of eggplant, it is best not to chase the phosphate fertilizer so as not to promote seed development in the fruit, and the seed coat hardens to reduce the commercial value of the eggplant fruit. During the fertilization process, it is necessary to grasp the principle of applying organic manure and supplemented by chemical fertilizers. The amount of chemical fertilizers should not be too large, especially nitrogen fertilizers, so as to avoid large accumulation of nutrients in the flower buds, resulting in the formation of carpels in the process of cell division. It even leads to the accumulation of nitrate in eggplant tissue.
With the economic development, the popularization of traffic lights has made the roads more and more orderly. We can see different types of traffic lights on the highway when we walk and drive. There are red and green traffic lights, red, yellow and green. Traffic lights, pedestrian lights, pedestrian countdown lights, arrow traffic lights, bicycle traffic lights, countdown traffic lights, etc. The current penetration rate of traffic lights in cities is over 80%. Do you know the purpose and composition of traffic lights?
1. When the green light is on, vehicles can pass, but turning vehicles shall not hinder the passing of straight vehicles and pedestrians.
2. When the yellow light is on, vehicles that have crossed the stop line can continue to pass; other vehicles are waiting to pass. Or observe the left and right and pass under safe conditions.
3. When the red light is on, vehicles are prohibited.
4. At intersections where non-motor vehicle signal lights and crosswalk signal lights are not installed, non-motor vehicles and pedestrians should pass according to the signs of motor vehicle signal lights. follow traffic rules.
5. At some marked intersections, when the red light is on, vehicles turning right can pass without obstructing the passage of vehicles and pedestrians.
6. Traffic signals can make vehicles run in an orderly manner, reduce traffic congestion, and reduce traffic accidents, so that all traffic participants can drive in an orderly manner, avoiding the time waste caused by traffic congestion and the life and property caused by traffic accidents. loss.
The composition of traffic lights: traffic lights are composed of red, green, and yellow lights.
Types of traffic lights: Traffic lights are divided into motor vehicle lights, non-motor vehicle lights, crosswalk lights, lane lights, direction indicator lights, flashing warning lights, road and railway intersection lights.
Traffic accidents that do not follow the directions of traffic lights and run red lights are repeated. The root cause of these problems may be related to childhood education and traffic safety awareness. Because the road traffic signal signs in counties and towns have not been widely popularized, or because there are few road vehicles in towns, people running red lights and becoming a habit, so how to avoid these problems, we need to grasp the root of the problem. Improve people's awareness of traffic safety and strengthen the learning of traffic safety knowledge.
