Analysis of the role of sulfur powder in promoting plant growth and development
As we all know, sulfur powder not only plays an important role in plants but also plays a very active role in pharmacology. Sulfur powder is an acidic compound, which can be used in flowers, trees, and fruit trees. It has the functions of sterilization and antisepsis, adjusting acid-base, promoting wound healing, preventing and controlling diseases, and can also provide plant nutrients and promote growth and development.
Control rotten roots. For example, Clivia often has rotten roots due to excessive watering or unclean culture soil, you can knock it out of the basin, remove the culture soil, cut off the rotten roots, rinse the roots with water, air them slightly, spray sulfur powder when the roots are slightly moist, and then plant them with sterilized culture soil, and new roots can grow in about a month; If all the roots are rotten, they can be planted in plain sand after spraying sulfur powder. Often spray water on the leaves. After new roots grow, they can be cultivated with sterilized culture soil. When the rotten roots of big trees turn yellow, the root-soil should be cut, the rotten roots should be cut, the sulfur powder should be spread on the roots, and the fresh sterile soil should be covered, which can prevent the rotten roots from continuing and restore the normal growth.
Prevent cuttings and flowers from rotting. When cuttings of Camellia, Rhododendron, and other fruits and flowers are raised, the cuttings are dipped with sulfur powder at the base of cuttings, which can effectively prevent cuttings from rotting and greatly improve the survival rate. Dipping sulfur powder in the base of flower arrangement can prevent the cutting from rotting, reduce the decay rate and prolong the ornamental period of flower arrangement. If the cuttings of Camellia and Rhododendron are dipped in sulfur powder and directly inserted into the pine leaf humus soil disinfected with potassium permanganate, the survival rate can reach more than 90%.
Prevent bleeding. The roots, branches, and leaves of plants prone to bleeding, such as fig, grape, banyan, and cycas, can be trimmed and coated with sulfur powder to inhibit bleeding, prevent wound infection and decay, and promote healing.
To prevent and control powdery mildew, plants such as flowers, trees, melons, and fruits should be sprayed with sulfur powder when the leaves are wet or dewy and sprayed with sulfur powder suspension or lime sulfur mixture in dry weather. Under the conditions of high temperature, high humidity, and poor ventilation, rose and Lagerstroemia indica is prone to powdery mildew. Fungicides such as carbendazim, and Bordeaux liquid have poor control effects and can not control the disease, but the sulfur powder is used to control the disease. The method is: first spray the sick plant with the sprayer (with sulfur powder adherence), and then use the duster to spray the sulfur powder on the sick branches and leaves. For powdery mildew of potted flowers, you can wash the small spray pot of Guilin Watermelon Frost (medicine for treating oral ulcer), dry it in the air, and spray it with sulfur powder. A small amount of sulfur powder can be put from the big end to the diseased part and blown from the small end. The sulfur powder will be evenly scattered.
Prevent the harm of salt and alkali. In the waterlogged and hardened saline-alkali soil, applying a certain amount of sulfur powder can adjust the soil pH value, reduce the salinity, and promote the normal growth of fruits and flowers.
Sulfur powder plays an important role in our production and life. In the future, the sulfur powder will play a more important role.
