Cultivation techniques of young and weak seedlings of orchids

The main results are as follows: 1. When dealing with young and weak seedlings, rinse the soil impurities in the roots, stems and leaves with clean water, cut off the rotten roots and fallen leaves, soak them in 0.5% topiramate solution for 5 minutes, then take them out to dry, and wait until the roots are slightly white. it can be cultivated in the basin.

2. fine sawdust with uniform particles should be used in the cultivation substrate, which should be fresh and free of decaying impurities. after cooking or exposure, it can be used in the pot after 1 or 2 days of air conditioning. single plant, double plant, or multiple plants can be planted together. Because of the strong water retention of sawdust, the temperature is slightly higher than the soil temperature, which is beneficial to the growth and root bud differentiation of orchid seedlings.

3. After potted cultivation, the orchids were watered thoroughly, and after drying for 1 or 2 days, the mixture of 0.3% chemical nutrient solution and 0.2% topiramate was sprayed. After spraying, clean water was sprayed on the leaves once a day in the evening. After half a month, it was sprayed every other day. The mixture of 0.3% nutrient solution and 0.1% topiramate was applied every 10 days, and the humidity of the basin soil was kept at about 70%. After every month, the roots and seedlings could sprout and grow gradually. After 3 years, the pot was turned over and planted with a mixture of 7% rotten soil, 2% coarse sand and 1% mature barnyard manure, and entered the normal cultivation management, which could blossom in about 4-5 years.

4. strengthen observation during the cultivation of young and weak orchid seedlings, pay attention to climate change and temperature difference between day and night at any time, and do a good job of temperature adjustment in time, requiring bright scattered light and avoiding the wind.

Young and weak orchid seedlings can also grow into strong orchids through scientific and reasonable cultivation, as long as we need to master the correct methods.
