How to use flower vermiculite?
In addition to potting soil and regulators, it is also used for soilless culture. As a nutrient base for growing potted trees and commercial beds, it is especially advantageous for the transplanting and transportation of plants. Vermiculite can effectively promote plant root growth and seedling growth is stable. Provide water and nutrients necessary for plant growth for long periods of time and maintain the stability of root sun temperature. Promote faster growth of plants;
Vermiculite used in agriculture and horticulture is a specially made expanded vermiculite, whose main function is to increase the aeration and water retention of soil (medium). Because of its fragile, with the use of time to extend, easy to medium dense and lost ventilation and water retention, so coarse vermiculite better than the use of long time, and the effect is good. Even the seeding medium of fine seeds and the covering for seeding are better with thicker ones. In horticulture, expanded vermiculite can be used for the cultivation of flowers, vegetables, fruits, seedlings, and so on. It is also suitable for planting lawns. Because it allows crops to get adequate moisture and nutrients from the early stages of growth, they allow plants to grow rapidly. It can be mixed with peat, peat, perlite, and it is also one of the main materials of the growing medium, and at the same time as the covering of seeding, adjusting the pH value of medium.
Vermiculite is a mica material formed when the silicate material is heated at high temperature. During the heating process, the moisture content of the silicate material is rapidly lost and expanded, and the volume after expansion is 15 times the original volume. Thus, the aeration pore and water holding capacity of the substance are increased.
Vermiculite has the characteristics of water absorption, cation exchange and chemical composition, so it has many functions such as fertilizer preservation, water retention, water storage, air permeability, mineral fertilizer and so on. The experiment shows that adding the expanded vermiculite of 10-20% into compound fertilizer can increase crop yield by 15-20%. Characterized by: light quality, good adsorption of water and fertilizer, no rot, can use 3-5 years.
In agriculture, vermiculite can be used as a soil conditioner, because of its good cation exchange and adsorption, water storage structure, moisture can improve the soil and improve the permeability of soil and water, acidicto neutralsoil; vermiculite can also play a buffer action, hindering the rapid change of pH value the fertilizer slow release in crop growth medium, and excessive use of fertilizers and allowing no harm to plants; vermiculite can also provide a K, Mg, Ca, Fe, Mn, Cu, Zn trace elements to crops
