The use of a large number of elements of water-soluble fertilizer as a quick-acting fertilizer, its nutrient elements are more comprehensive, and according to the fertilizer characteristics of different crops, the corresponding fertilizer has different formulations, the market sells vegetables, fruit trees, flowers, grain, cotton, A special water-soluble fertilizer for various crops such as oil. Due to the high price of water-soluble fertilizers, it has not been widely spread. The general consumption areas are mainly concentrated in greenhouse vegetable production bases, fruit tree production bases and some flowering areas, such as Liaoning, Hebei, Shandong, Xinjiang, Sichuan, Guangxi, Yunnan and Hainan are key consumption areas for water-soluble fertilizers. Due to the short growth cycle of vegetables and high economic benefits, consumers have high requirements on the quality of vegetables, and the demand for fertilizers by vegetable farmers is also high. A large number of elemental water-soluble fertilizers have become the preferred fertilizer for vegetable farmers, and the quality vegetables grown can be sold. Good prices bring high profits, so vegetables become the main consumers of water-soluble fertilizers. For field crops, because of their high cost, people are generally reluctant to invest, or only accept traditional fertilizer.
Precautions
1. Do not spray on rainy or foggy days. If it is raining within 4 hours, it should be reduced and refilled once;
2. For fertilizers that have not been used up after opening, they should be tightly stored to prevent moisture;
3, please seal in normal temperature, cool, dry place to store, if the water soluble fertilizer does not affect the fertilizer effect;
4. The amount per acre, the concentration of water, and the number of applications should be increased or decreased according to the season and crop growth;
5, this product is stored in a cool dry place, if there is agglomeration does not affect the fertilizer effect.
Optical Bandpass Filters are used to selectively transmit a portion of the spectrum while rejecting all other wavelengths. Optical Bandpass Filters are ideal for a variety of applications, such as fluorescence microscopy, spectroscopy, clinical chemistry, or imaging.
An optical bandpass filter has a transmission band surrounded by two blocking bands that allow only a portion of the spectrum to pass. These optical bandpass filters have broad spectral bandwidths in either the ultraviolet, visible, or infrared spectrums. The nearly black filters absorb visible radiation. They are perfect for ultraviolet or infrared detection applications. UV filters are often used to selectively transmit the 254nm and 365nm mercury lines. IR filters are often used in nightvision and IR sensing systems.
