Matters needing attention in the pot of new grass and weak seedlings

Recently, the activities of buying grass and turning pots have entered the peak season. Write a post for Lanyou for reference: only when the roots of bluegrass seedlings are in good condition and growing vigorously can they have better absorptive capacity. With a good root system, fertilization can help orchids grow better and promote growth. If the root system is very weak, and then apply fertilizer blindly, it will make things worse, which may cause a bad cycle and make good orchids die. Therefore, as the saying goes, "raise orchids and grow roots first". If weak seedlings are divided into pots (according to the principle of "maximum prosperity, extreme failure", weak seedlings and sick seedlings should turn the pot as early as possible. ) should pay attention to several points: 1, clear and nourish: can be used to change the basin to cultivate the soul soil, because the soil contains light fertilizer elements, and contains blue bacteria, so it is very suitable for small and weak orchid seedlings. Forbid fertilizer and nourish in the shade. (note that the light is not too strong, the ventilation is not too strong, and the plant material is not too wet.) 2, if the roots of weak seedlings are few, as long as they are not sick, they can be accompanied by healthy flowers, so weak orchids can be rejuvenated by supplying the physiological vitality of healthy orchids and repairing their roots. After rejuvenation, a small amount of external root fertilizer can be applied. 3. According to the theory of "raising roots in dry pot", the upper basin moisture of weak grass should be drier than that of normal orchid grass, and the plant material should be highly leachable and adopt larger granule species. 4. The light should be overcast, and the yin and yang should be leveled with "dry basin yin and nourishment". Orchids grow at night by photosynthesis at night for cell division and proliferation at night. Yin culture can reduce transpiration, reduce the negative energy of roots, and promote the healing of near roots and injured roots. 5. Ventilation. The weak breeze is more suitable, if the weak and diseased seedlings are placed under the larger convective wind, the orchid seedlings can be dehydrated and withered, resulting in death. The above are the matters needing attention in turning the basin of weak grass, and the new grass (the grass you just bought) can also be used for reference. However, attention should be paid to disinfection and temporary isolation from the good grass at home for a period of time (about 10 days). After observation and normal, it can be put on the shelf and raised with other cooked grass.
