Two misunderstandings in cultivating Orchid

Author: F123

1. Wrong concept of "plant disinfection". Orchids are symbiotic plants with root fungi. Only the orchids around the roots provide nutrition to the roots, orchids can obtain sufficient growth nutrients. Whether it is healthy or not, the use of fungicides to "disinfect plants" before cultivation actually destroys the growth conditions of this natural balance, and the consequence is that orchids have to reproduce orchids. Longer incubation time leads to slow growth of seedlings, roots, buds, etc. Seriously, the alkalinization of plants will produce anaerobic harmful bacteria, for a long time, orchids can not absorb nutrients for a long time, the number of anaerobic harmful bacteria is too large, orchids will slowly get sick. It is correct to disinfect the wound when the orchid is divided into seedlings. Blue bacteria can be divided into beneficial bacteria (aerobic bacteria, aerobic bacteria) and harmful bacteria (anaerobes). As long as in an oxygen-rich environment, Yilan bacteria occupy the plant space, beneficial bacteria can inhibit harmful bacteria, that is, orchids produce rotten roots, seedling rot and other bacteria are difficult to survive and reproduce. This is a concept that must be fully understood.

2. Wrong concept of "nutrition". First of all, it must be understood that there is an essential difference between the cultivation of orchids and the cultivation of vegetables. Fertilizer should not be used casually to provide nutrition to orchids. In addition to foliar fertilization, base fertilizer essentially provides a superior and nutrient-rich environment for orchids, rather than acting directly on the roots. Orchids are slightly acidic plants, Yilan bacteria are also microorganisms that like slightly acidity and oxygen, and harmful bacteria are anaerobic bacteria that like alkaline substrates. We can only use slightly acidic plants on the cultivation substrate as far as possible, such as Yunnan red soil, red willow bark, pine needles, thorn oak leaves, green bar bark, etc., learn to water, water can bring fresh air (oxygen) into the plant material. To make the orchids beautiful.

On the key points of the management of Yunnan ear leaf mixture: in the successful management experience of orchid cultivation in Yunnan, heavy water management is the key. The so-called heavy water management is the need for frequent watering, the advantage of frequent watering is to bring fresh air into the plant material, Yilan is aerobic bacteria, harmful bacteria are anaerobes. Watering frequently can improve the permeability of the whole plant material, and if there are a large number of aerobic bacteria in the plant material, the orchid will naturally grow well. About the correct method of watering: watering before going to bed at night is the most correct method. If the temperature is low at night and there is no sunlight, water will not have a "photothermal effect" with light and heat (high temperature). Without the harm of photothermal effect, orchids will naturally be healthy and won't get sick. Watering needs to be watered twice, and only once at an interval of 10-20 minutes can it be watered thoroughly. Orchids grow basically in the middle of the night. If they are watered thoroughly, the orchids will grow quickly. Watering management: water frequently when the temperature is high, water every few days when the temperature is low, watering frequency should be linked to the temperature, 15-20 degrees should be watered every 3-4 days, 20-25 degrees should be watered every other day, and above 25 degrees should be watered every night. Finally, there is another key point: after pouring water at night, we must strengthen ventilation, open the window as far as possible, and blow dry the water in the heart of the seedling, and the temperature is high during the day. Don't spray water on orchids.
