Application principles of potassium fertilizer

Generally, the potassium content in the various tissue parts of Chinese orchids differs; the leaves contain more potassium, followed by new roots. However, during the maturity stage, Chinese orchids have the most potassium in the corm. Therefore, if you want to cultivate Chinese orchids with a vigorous root mass, thick and large roots, thick and large corms, thick and lustrous leaves, and enhanced disease resistance, in dailycultivationmanagement work matters of "fertilizer management," you should use more organic plant-based growth agents containing low nitrogen and high potassium N, P, K, with a content of 15-15-3O high-unit potassium fertilizer. Promote root mass development, enhance nutrient absorption and effective utilization, and strengthen the orchid plant's growth vigor and resistance to adverse environments, prevent aging, so that the Chinese orchids cultivated become healthier and stronger with each generation, and quality and yield are further improved. Potassium fertilizer is the element most easily deficient in various plants, and of course Chinese orchids are no exception. When potassium is deficient, the leaf margins and leaf tips are relatively prone to necrosis, producing scorched and withered phenomena, commonly called "scorched tips"; leaf tissue is tender, the maturity stage is delayed, the corm is small, and disease resistance is reduced. Sometimes excessive use of nitrogen fertilizer also makes this more likely to occur. Chinese orchid growth varies according to its growth stage; supplying different equivalent amounts of potassium fertilizer can help Chinese orchids have broad and thick stems and leaves, enlarged corms, improved disease resistance, enhance photosynthesis of Chinese orchids under weak light, accelerate the progress of photosynthesis, increase nutrient absorption, and promote the growth and development of Chinese orchids. Potassium fertilizer is more easily deficient in acidic soil and in Chinese orchid media that are frequently leached by water, and the potassium in chemical fertilizers is also more easily lost or used in excessive amounts, resulting in fertilizer damage. Generally, Chinese orchidscultivationin dailycultivationmanagement, you should use more water-soluble organic low-nitrogen high-potassium plant growth promoters to cultivate Chinese orchids. According to differences in growth stage, the principles for applying potassium fertilizer are: (1) At division: You may place 1-2% organic fertilizer, or two weeks after dividing and planting place a slow-release long-acting organic fertilizer, or apply an organic plant-based growth promoter once a week. (2) From budding stage to vegetative growth stage: If the medium contains a relatively high amount of nitrogen fertilizer, applying too much nitrogen fertilizer is likely to cause excessive vegetative growth in Chinese orchid plants. At this time, it is advisable to apply "low-nitrogen high-potassium" organic fertilizer to avoid changes in the plant body, tender tissue, and reduced disease resistance. At this time, you may alternately use a balanced N, P, K content of 20-20-20. For nearly half a century, the domestic economic level has advanced by leaps and bounds, national income has risen, and people's demand for quality of life has increased day by day. Chinese orchid cultivation has successively adopted specialized cultivation and management models. Therefore, large amounts of chemical fertilizers and pesticides have been applied, and coupled with leaching by water, this has led to many deficiencies such as reduced organic matter content in the medium, deteriorated physical and chemical properties, nutrient loss, and weakened medium productivity. Thus, the application of organic agriculture in Chinese orchid cultivation uses crop residues, animal manure, mosses and other organic materials, and uses beneficial microorganisms to decompose and release nutrients, applying them to Chinese orchid crops to achieve the goal of Chinese orchid production.
