In Lianyungang City, Jiangsu Province, a specialized rice planter has used ternary compound fertilizers in rice for basic fertilizers in recent years. After planting rice cultivars, small urea or ammonium bicarbonate is used as a tiller fertilizer. The effect has been good. He feels that it is very important to produce topdressing fertilizers. Although the amount of application is not large, it must be applied in a timely manner and the results will be good. To use it when the seedlings are eased, rice will begin to grow. If nitrogen fertilizer or topdressing is not applied at this time, seedlings will have fewer tillers, which will affect the later production. According to his many years of experience, if you use ammonium bicarbonate in your tillering fertilizer, you can use 7 to 10 days after planting the earthworm. The amount of ammonium bicarbonate is usually 10 to 15 kg/mu. If you use small-size urea as the top dressing, the amount should be halved. It can take 3~4 days in advance to catch up. The experiences of the past few years have been summarized, and the application of these two nitrogen fertilizers is as effective. In 2006, when the use of manure was changed, when it was necessary to use nitrogen fertilizer, the agricultural distribution shop recommended him a large-particle urea. He also said that the large-particle urea was of good quality without caking and the price was not high. So the specialized rice planter bought a large grain of urea and used it as a topdressing fertilizer for rice tiller. He used the method of using small particles of urea in previous years, but he observed that the effect of large-particle urea as a rice tiller does not appear to be as good as small-particle urea. He does not understand how big the difference between granules of urea is.
Expert Comments: The same and differences in size of granular urea are compared here. The same thing, their effective components are water-soluble fast-acting urea molecules, and the nitrogen content is 46%, the only difference is that the particle size is different. The particle size is mainly affecting the rate of dissolution. The speed of dissolution and release of small particles of urea in water or in soil is slightly faster, and the dissolution and release of large particles of urea in soil is slightly slower. This difference is reflected in the application method, that is, when urea is used as top dressing, the fertilizer efficiency of small particles is slightly faster than that of large particles. From the perspective of loss, the loss of large particles of urea is smaller than that of small particles. In general, the difference between the speed of the two fertilizers is very small. Such as at 20 °C at room temperature, their release rate in the soil is a difference of 2 to 3 days. For the absorption and utilization of crops, urea is a molecular nitrogen. The amount of urea directly absorbed by the crop is small, and it can only be absorbed in large amounts in the soil after it is converted into ammonium nitrogen. Therefore, urea, regardless of particle size, should be applied several days ahead of ammonium bicarbonate for top dressing application. In addition, the particle size of large urea is similar to that of diammonium phosphate. Therefore, large-particle urea can be blended with diammonium phosphate as base fertilizer, and it is better not to use large-granule urea as top-dressing.
The case shows that the dissolution rate of large-particle urea is slightly slower and is suitable for basal fertilizers. It is not suitable for top-dressing and red-fertilizer application. Its particle size is matched with diammonium phosphate and can be used as a material for compounding compound fertilizers.
Car Blanket is also called as auto blanket, as it is normally used for keeping warm in the car.
As a result, it is normally used in the open air. When people go out for a picnic and want to have a snap in the daylight or even spend the whole night outside, then the car blanket would be a best choice for you.
It uses 12V voltage, rather than AC power.
You just need to plug it into cigarette lighter of your car, and it the blanket will keep you warm.
