1、 Method of use

When using potassium dihydrogen phosphate in cultivating orchids, the most important thing is to pay attention to the concentration. When in use, spray 1000 times the solution, and the concentration must not be too large, otherwise its leaves and flower buds will be corroded. The spraying period should be more uniform, and more attention should be paid to spraying the front and back of plant leaves. It can also be used for root irrigation, and the proportion is 1000 times

2、 Frequency of use

Proper use can help it grow, but if it is used too often, it will affect its growth. Generally, use it 2-3 times. Root irrigation is usually used once a half month or once a month. In addition, we must pay attention to its purity and quality when buying, so as not to achieve bad results

3、 Usage time

The best use time is about 9 o'clock, which is conducive to plant absorption. If it is carried out when the temperature is too low, freezing injury will be formed. When spraying, the temperature should be kept at about 12 ℃ as far as possible, and the use effect of this temperature range is the best
