Rejuvenation of weak seedlings in Orchid planting

It is difficult to rejuvenate the weak seedlings of orchids. Practice has proved that in order to rejuvenate weak seedlings, all measures must be in line with its growth law, patient maintenance with a normal state of mind, steady and slow, and never act in undue haste. As long as the plant materials are selected and the management keeps up, the weak seedlings of orchids can be completely rejuvenated.

The main results are as follows: (1) Select the mixed plant material which is breathable and leached and rich in nutrients: the mixed plant material is better. It is best to use the mixed plant material containing sieve orchid mud to cultivate weak seedlings, accounting for 1 × 3, thick to fine, especially around the false bulb with fine grains of 3 mm in diameter, which is beneficial to the new root growth of weak seedlings. With deep roots and luxuriant leaves, only when the roots are well cultivated, can the weak seedlings be rejuvenated, otherwise, everything will be out of the question.

(2) the orchid basin should be small, do not turn the basin too frequently: the weak seedlings of orchids, the root system is underdeveloped, and the pot should be small rather than large. It is difficult to dry out with large potted weak seedlings and small seedlings, which can easily lead to rotten roots and inverted seedlings. Weak seedlings grow slowly and should be quiet and unmovable. if you don't see the disease, you can't turn the pot. it's hard for the seedlings to grow up after turning the basin.

(3) it should be cultivated in the same pot with strong seedlings: practice has proved that the more orchid bacteria in the root system of the stronger orchid plant, the more orchid bacteria are more beneficial to the growth of orchids. On the other hand, most of the blue bacteria around the roots of weak seedlings are not active, and the growth of orchid plants is slow. Therefore, if you want to rejuvenate the weak seedlings, it is best to find her a "wet nurse", that is, it should be planted in the same pot with the strong orchid seedlings, so that they can grow in an active environment of orchid bacteria and promote growth with "strong" and "weak", with good results.

(4) appropriate shading: weak seedlings should be yin rather than yang, it is better to scatter light, it is necessary to wait for leaves to be slightly affected in the morning, oh, gradually exercise to adapt. Weak seedlings are suddenly exposed to strong direct sunlight and are vulnerable to injury.

(5) appropriate recuperation: weak seedlings grow weakly and do not need much fertilizer, especially in the dormant period. "deficiency is not compensated", more fertilization will be counterproductive. The general requirement of raising weak seedlings is dry literacy, plant materials should be dry but not dry, moist but not stained. Fat and wet, often not easy to root, or even not root. Watering can not be sprayed with water, generally should not be caught in the rain, otherwise perishable seedlings.

(6) create suitable air humidity conditions: raise weak seedlings, the air humidity should not be too high or too low, and the air relative humidity should be 40% and 70%.
