This Christmas tree uses the principle of capillary phenomenon. When the paper tree is immersed in a salt solution, the solution rises rapidly in the paper tree by capillary phenomenon, reaching the end of the paper tree branches, and the water at the end evaporates first, so there will be crystallization. These solutions absorb the colored pigments painted on the paper tree in advance, so colorful flowers grow on the tree.

The height of colorful magic Christmas trees is usually less than 10 cm, and they are generally composed of two paper shells, which are generally coated with colorful pigments. Buyers only need to put the two paper shells in a small dish and pour a package of transparent liquid inside.

Extended data:

Used as buffer and culture medium in industry; It can also be used as flavoring agent of bacterial culture medium, raw material for synthesizing green trees, making potassium phosphate, culture medium, enhancer, starter and fermentation aid of Saccharomyces cerevisiae.

Application of high-efficiency phosphorus-potassium compound fertilizer in agriculture Potassium dihydrogen phosphate products are widely used in all kinds of cash crops, grain, fruits, vegetables and almost all kinds of crops. Widely used in drip irrigation system.

Potassium dihydrogen phosphate has many excellent effects, such as significantly increasing yield and income, improving and optimizing quality, resisting lodging, disease and insect drug resistance, preventing premature aging, and so on. It also overcomes the influence of nutrient deficiency and the growth of root crops in the late aging period caused by the decrease of absorption capacity. It can control the growth of cotton and increase the number of flower buds when used on cotton.
