Hello everyone, I am your old friend Deep Mountain Lannu, northern balcony orchid lovers, like to share orchid conservation experience, like friends on the like to pay attention to the next [come to see me] [come to see me] [come to see me]
Recently, many friends are turning the orchid pot, the previous article and everyone talked about several factors that need to be considered in the pot, interested friends can open it to see. The most intuitive way to turn the pot is to observe Langen, experienced friends through the growth status of Langen, you can be very sensitive to understand the advantages and disadvantages of their own maintenance, in the maintenance to correct, you can do more with less, quickly improve the level of orchid farming. Below, Deep Mountain Lanu combines some of his own experiences to talk to you about what can be observed from Langen.
One is to look at the flat and concave. The root system grows in the pot, and when it encounters obstacles, it will change the direction of growth. From this characteristic, we can very easily observe the growing medium used by the merchant, the langen raised by the granular growing medium usually has a clear sense of concave and convex, and the distortion is more, while the langen raised by soft growing medium is generally more straight.
The second is to look at the form. Orchid friends know that the market is full of a large number of tissue culture seedlings, hormone seedlings, greenhouse seedlings, etc., fish and dragons mixed, from the root growth form, we can intuitively see the source of orchids, the general tissue culture seedlings, the root system is relatively delicate and short, almost no bending changes; hormone seedlings are generally manifested as more root bifurcation, uneven thickness, more exuberant; greenhouse seedlings root skin is thinner, fine root tip, less crystal head.
The third is to look at the color. After turning the pot, we saw that the orchid root color was mainly jade white, yellow-brown, black and green. Jade white is the most robust root system, this root system, absorption and transformation ability is very strong, this root system is not tolerant of large water and fertilizer, is the best guarantee for orchid growth. Yellow-brown is generally old roots, or the growth environment water and fertilizer are relatively sufficient, the air permeability is not very good, the lignification is more serious, and the role of orchid growth is relatively small. The black root system is generally going to rot away, either the growth life has arrived, or the water and fertilizer in the pot are too much, and the growing medium is poorly breathable, resulting in damage to the root system and forming an unhealthy state, which should be cut off immediately when it is seen. There are fewer green roots, but there are also, generally after the root system is illuminated, and this root system can also function normally without fuss.
The fourth is to look at the length and shortness. The healthy root system of orchids is roughly the same as the length of orchid leaves, and the error is ±30%, which can be regarded as normal. As the saying goes, how tall a tree is, how deep the roots are. It is also more suitable for use in langen. Short is generally the growing medium fertilizer, sufficient water, long is generally the growing medium lack of nutrients, less moisture.
Fifth, look at the thickness. Orchid root system is generally thick and uniform, the average thickness of each orchid is not the same, like the root system of hui lan is thicker than the spring orchid, I have not counted the thickness in detail, can only say that when you observe the thickness of the orchid, take your own observation as the standard, generally more stout orchid root, the water fertilizer in the planting medium is sufficient, the more slender orchid root, the water fertilizer is relatively thin. If the root system is a thick section and a thin section, uneven, then it can be seen that in the different periods of orchid root growth, water and fertilizer management is not uniform, and later management should pay attention to.
Sixth, how much to see. How much the root system and the growth state of the orchid have a lot to do with it, if the orchid grows vigorously, the nutrients needed are more, in the case of each orchid root absorbing nutrients relatively fixed, it will send more orchid roots from the head of the reed to supply orchid growth, but too much orchid root will also affect the air circulation in the pot, easy to cause rotten roots, orchid root system is more Generally the nutrients in the pot are relatively lacking, and when the pot is on the pot, we must pay attention to pruning the weak roots of the old root disease, and appropriately increase the proportion of organic matter in the growing medium.
Finally, to tell you about it, the normal orchid root is white, the crystal head is more, the thickness is uniform, compared with the orchid root of their own maintenance orchid, you can see the deficiencies in water and fertilizer management, in the daily maintenance to pay more attention to ensure the healthy growth of orchids.
Today's topic will talk to you here, like friends on the praise and attention to the deep mountain Lannu, thank you for your support [come to see me] [come to see me] [come to see me]
