What are the key technical points of fertilizer and cultivation management?

Throughout the entire growth process of Chinese orchids (Cymbidium), besides necessarily being subject tocultivationenvironmental influences, such as suitable light intensity for growth and a suitable temperature range for growth, with an appropriate amount of water supplied to promote growth, and appropriatecultivationmedium and fertilizer content, to promote root growth and absorption and other major factors,cultivationmanagers need to grasp the growth characteristics of different varieties of Chinese orchids. During routine cultivation management, they should use artificial supplementation methods, adding organic fertilizers or inorganic chemical fertilizers, to provide timely and appropriate "fertilizer and cultivation management," supplying the nutrients needed for Chinese orchid growth, promoting their growth and robustness. And in conjunction with the correct use of pesticides for timely and proper diagnosis and correct application, doingpest and diseaseprevention and control work, protecting Chinese orchids from harm by pathogens, insects, etc., and from unnecessary losses, ensuring normal growth and development of Chinese orchid plants, one can cultivate healthy and robust Chinese orchids with vigorous root systems, thick and plump stems, differentiated lateral buds, high shoot emergence rates, thick and glossy leaf flesh, and strong disease resistance, and can raise the return on investment for Chinese orchid growers, so as to achieve self-cultivation, physical and mental refinement, exercise of the muscles and bones, and also the economic benefit of increased income. Besides relying on light, temperature, water, and medium, plants must also be supplied with sufficient nutrient elements to maintain their normal growth, and the elements needed to maintain normal Chinese orchid growth are: Macro elements: carbon (C), hydrogen (H), oxygen (O), three parts; Major elements: nitrogen (N), phosphorus (P), potassium (K), calcium (Ca), magnesium (Mg), sulfur (S), six parts; Trace elements: copper (Cu), iron (Fe), zinc (Zn), manganese (Mn), boron (B), chlorine (Cl); And under certain circumstances, elements such as silicon (Si), sodium (Na), aluminum (Al) that are helpful to Chinese orchid growth. During the process of growth and development, Chinese orchids must take in carbon dioxide from the atmosphere, and take in water and oxygen from the roots. Carbon dioxide enters through the stomata of the leaves, while water is absorbed by the roots, and the chlorophyll in the leaf tissues absorbs the radiant energy (heat energy) of sunlight, carrying out photosynthesis to convert it into carbohydrates, for Chinese orchid growth and the ability to produce organic matter (the organs such as roots, stems, and leaves are called organic matter) and reproduce the next generation. The "carbon" of macro elements is mainly supplied by carbon dioxide in the atmosphere, root respiration, and CO2 (carbon dioxide) released by the microbial decomposition of plant remains, for use by Chinese orchids. [Hydrogen and oxygen] mainly come from the supply of water and air. Within the critical points of light and temperature suitable for Chinese orchid growth, the stronger the sunlight intensity, the more vigorous the assimilation of carbon monoxide, and the growth rate of Chinese orchids increases correspondingly. And when the oxygen in the atmosphere and the oxygen required by the roots are insufficient, the growth rate of Chinese orchids increases correspondingly. And when the oxygen in the atmosphere and the oxygen required by the roots are insufficient, the growth of Chinese orchids and the elongation of the roots will be hindered. Water is the main component of protoplasm, and is used to maintain the osmotic pressure and turgor pressure of Chinese orchid cells and maintain the metabolism of all substances within the cells, and to dissolve various nutrients for Chinese orchid growth. Whether the ratio of water within the Chinese orchid root system and carbon dioxide in the air is appropriate is an important factor determining Chinese orchid growth. If cultivation managers can pay more attention to water, oxygen, and carbon dioxide in their daily routine, then the production yield of Chinese orchids can certainly be greatly increased.
