Key points of Fertilizer Management

In the whole process of the growth of national orchid, in addition to being affected by the cultivation environment, such as light intensity suitable for growth, temperature suitable for growth, appropriate supply of water to facilitate growth, appropriate cultivation medium and fertilizer content, in order to promote root growth and absorption and other main factors, cultivation managers need to master the growth characteristics of different varieties of national orchid, and usually use artificial addition methods for cultivation and management. Add organic matter fertilizer or inorganic fertilizer, give timely and appropriate amount of "fertilizer management", supply the nutrients needed for the growth of national orchid, and promote its growth and health. And cooperate with the correct use of pesticides to diagnose correctly, use drugs correctly, do pest control and other work, protect the national orchid from the harm of pathogens and insects, suffer unnecessary losses, and ensure the normal growth and development of the national orchid plants. that is, it can cultivate a healthy and strong national orchid with exuberant roots, hypertrophy of stems, lateral bud differentiation, high budding rate, thick and shiny mesophyll and strong disease resistance. It can also improve the rate of return on investment of national orchid growers, so as to achieve self-cultivation, cultivate body and mind, exercise muscles and bones, and increase income at the same time.

In addition to relying on light, temperature, water and media, plants need to provide sufficient nutrients to maintain their normal growth, and the elements needed to maintain the normal growth of the national orchid are:

Huge amount of elements: carbon (C), hydrogen (H), oxygen (0), three parts

Main elements: nitrogen (N), phosphorus (P), potassium (K), calcium (Ca), magnesium (Mg), sulfur (S), etc.

Trace elements: copper (h), iron (h), zinc (h), manganese (Mn), boron (B), chlorine (C1)

And silicon (Si), sodium (NA), aluminum (A1) and other elements which are helpful to the growth of national orchid in some cases.

In the process of growth and development, Guolan must absorb carbon dioxide from the atmosphere and water and oxygen from the roots. Carbon dioxide enters through the stomata of the leaves, while water is absorbed from the roots, and the chlorophyll of the leaf tissue absorbs the radiant energy (heat energy) of sunlight, which is converted into carbohydrates by photosynthesis. to provide the ability for the growth and proliferation of organic matter (such as roots, stems, leaves and other organs, namely organic matter) to reproduce the next generation.

The "carbon" of huge amounts of elements is mainly made up of carbon dioxide in the atmosphere, root respiration and CO2 (carbon dioxide) released from plant remains by microbial decomposition, which is used by the national orchid.

[hydrogen and oxygen] mainly comes from the supply of water and air. At the critical point of light and temperature suitable for the growth of Chinese orchid, the stronger the intensity of sunlight is, the stronger the assimilation of carbon monoxide is, and the growth rate of national orchid increases correspondingly. When the oxygen in the atmosphere and the oxygen needed in the root are insufficient, the growth rate of the orchid increases. When the oxygen in the atmosphere and the oxygen needed by the root are insufficient, the growth and root elongation of the orchid will be hindered. Water is the main component of the protoplasm. it is used to maintain the osmotic pressure, turgor and metabolism of all substances in the cells, and to dissolve various nutrients for the growth of the orchid.

Whether the proportion of water and carbon dioxide in the root system is suitable or not is an important factor that determines the growth of national orchid. If the cultivation managers can pay more attention to water, oxygen and carbon dioxide, the yield of national orchid production will be greatly increased.
