What is the cultivation medium for raising flowers?

1. Commonly used soilless medium.

Bagasse: Mostly used in the tropical Yuyou area, it has a high carbon-to-nitrogen ratio, and nitrogen must be added to meet the needs of rapid decomposition of microorganisms. Bagasse has a high water holding capacity, decomposes quickly in containers, and is prone to densification, resulting in poor aeration and drainage, so it is rarely used in potting mix media.

After the heap of rotting bagasse, mixed into the field soil, the key posture is especially for the clay, which can play a good role in changing the town of Lianghuai.

Bark: pine bark and hardwood bark, which have good physical properties and are able to partially replace peat as a potting medium. The main problem with fresh bark is that it is relatively high in carbon and nitrogen, and some barks, such as by bark, contain toxic components to plants, which should be degraded by composting or leaching.

Peat, perlite, vermiculite, volcanic stone, crystal clay, ceramsite, pine bark, moss, coco.

A medium is a general term for the materials used to support the growth of plants. In the traditional flower and seedling planting industry, the cultivation of plants is based on soil as the cultivation medium. However, in the application of soil in cultivation medium, due to the inconsistency of characteristics and poor aeration, drainage and water holding capacity, it is difficult to meet the needs of flower and seedling growth, and may bring biological pests and diseases to plants, which has been rarely used in the current cultivation.

In order to cooperate with the refined, scientific and industrialized production methods of modern flower and seedling planting industry, peat, vermiculite, perlite and a mixture of the two or three are generally used as cultivation media.

All kinds of culture soil (or nutrient soil) can be purchased on the market, and you can use it directly if you need it.

The pH of the medium (usually expressed in pH) affects the ability of plants to absorb nutrients. The pH test paper can be used to determine the pH of the medium, and the pH test paper can be purchased at general chemical reagent stores. The determination method is as follows:

Take a part of the medium, mix it fully with distilled water of 5 times its volume, stand for a period of time, take its supernatant, drop a drop on the test paper, and compare it with the color card attached to the test paper within half a minute to know its pH value, pH <7 is acidic, pH >7 is alkaline.

In recent years, the medium used in container cultivation has gradually tended to use the medium with no soil or little soil. This is because the large flushing and dismantling department of the soil medium focuses on the non-toxic type of horticulture, does not need to be disinfected, is light in weight and resistant to jujubes, has a balanced quality, is cheap, easy to dry and standardized. However, there is no soil medium, most of which contain no or less nutrients, and it is necessary to pay attention to the timely application of nutrient solution.
