Types and characteristics of fertilizers

Special organic fertilizer people said: organic fertilizer on the orchid plant is less irritating, there is no sign of decline in color, and to reduce and prevent the occurrence of Bellas disease.

Used to chemical fertilizer said: chemical fertilizer is made according to modern scientific methods, is the most scientific theory, the most ideal fertilizer. It is considered that the use of organic fertilizer is an ancient method not in line with the era of science.

The public argument is reasonable, and the mother-in-law is reasonable. The above two statements are inevitably suspected of being too extreme!

In fact, the composition of organic fertilizer contains not only the three elements of chemical fertilizer, but also some phytonutrients that have not been analyzed by scientific methods. Organic fertilizer does not have the immediate and rapid effect of chemical fertilizer, but it has the function of improving soil quality. Chemical fertilizer has an immediate effect, but continuous application is easy to suffocate and harden the soil. This is the general difference between organic fertilizer and chemical fertilizer! The author comes from a peasant family and has personally experienced the true facts mentioned below, that is:

Vegetables with special organic fertilizer have thick leaves, thick stems and branches, tender and crisp, delicious and popular. Vegetables with special chemical fertilizer have stiff leaves and stems, straight posture and long fiber in the body.

The edible sugarcane with special chemical fertilizer has hard stem, thick sugar, sweet and sweet, and everyone likes it. For sugarcane with special organic fertilizer, the stems and branches are fat and fragile, but the sugar is thin and the sugarcane juice is salty.

It can be seen from the above-mentioned facts that organic fertilizer and chemical fertilizer have different effects on crops. The composition of fertilizer is indeed different, and its effect on orchid plants is also different, and it is inevitable that each has its own advantages and disadvantages. Therefore, it is difficult to determine which is the ideal fertilizer for orchid plants.

The purpose of fertilization is to provide plants with rich nutrients. And plants in culture, often have the symptoms of malnutrition, or malnutrition. In particular, the use of stones, bricks or bark, etc., planted in a small pot of orchid plants, the extension of the root group is very small. There are also many cases of malnutrition, or malnutrition.

Under the circumstances that it is difficult to determine what state and which type of nutrients to lack for a long time, the author believes that we should try our best to use a variety of fertilizers with different ingredients, that is, organic fertilizers, chemical fertilizers and other fertilizers of different properties should be used in turn to prevent the lack of certain ingredients.
