1. The concentration is suitable for spraying to obtain good results. Generally speaking, the suitable spraying concentration of various micro-fertilizers is: boric acid or borax solution 0.05% to 0.20%, ammonium molybdate solution 0.02% to 0.05%, The zinc sulfate solution is 0.05% to 0.20%, the copper sulfate solution is 0.01% to 0.02%, and the iron sulfate solution is 0.2% to 1.0%.
2. The period of spraying micro-fertilizer must be based on vegetables and different micro-fertilizer varieties, and it is generally appropriate to spray before flowering.
3. The dosage is 50-75 kg per mu of fertilizing solution, which makes it possible to wet the stems and leaves of vegetables.
4. The number of times of spraying on the leaf surface is generally less than the amount of fertilizer used, so it is difficult to meet the needs of all growth and development processes once. Therefore, it should be sprayed 2 to 4 times according to the length of the vegetable growth period.
5. Date is to reduce the loss of micro-fertilizer during spraying, which is good for leaf absorption. It should be sprayed on cloudy or sunny afternoon to evening, which can prolong the retention date of fertilizer solution on vegetable leaves, which is beneficial to improve Spray effect.
6. Mixed spraying between micro-fertilizers and mixed with other fertilizers and pesticides can save the process and play the role of “one spray and multiple effects”. However, when mixing, pay attention to clearing the fatness and medicinal properties. If the properties are opposite, they are mutually obstructive and must not be mixed. All kinds of micro-fertilizers should not be mixed with alkaline fertilizers such as grass ash and lime. Zinc fertilizer should not be mixed with superphosphate. Copper fertilizer should not be mixed with potassium dihydrogen phosphate solution.

A major name in elevators and escalators since the 1930s, Mitsubishi Electric has built a reputation for creating breakthroughs that make getting around more comfortable, safe, and even inspiring. Take our spiral escalator, for example. A Mitsubishi Electric original, it`s not only fun to ride, but has opened up entirely new possibilities in public space design. Its development required years of dedicated effort to overcome the immense physical, technical and mechanical challenges involved. Then there`s our super high-speed elevator, the culmination of decades of engineering experience and precision craftsmanship. It provides an ultra-fast, reliable riding experience with imperceptible vibration and noise. And there`s artificial intelligence technology that [learns" a building`s traffic patterns to deliver a more responsive service. Mitsubishi Electric is dedicated to creating better point-to-point transport experiences for all. We`re also a leading manufacturer of moving walks and home elevators.
