Seed planting method of Cymbidium

Soak the seeds for about 40 ℃ for about 30 hours, remove and cool. The treated seeds produce radicles in about 17-20 days. Choose fine sand, wash and disinfect, spread it in a container, put the germination eyes of the seeds down, arrange them on the sand surface at an interval of about four centimeters, and cover them with a layer of fine sand, not too thick, a thin layer will do, and it will take about a month or so for cotyledons to grow.

1. Seed collection

In general, it is best for seeds to be sowed one or two days after they are taken out, when the seeds have more moisture and strong vitality, and the emergence rate of seeds placed for too long will be affected. Cut the fruit and the arrow scape together with scissors and peel off the seeds. If the delayed sowing time is delayed, hanging the seed and "arrow scape" in a cool and ventilated place can be preserved for about a month, but the emergence rate will be reduced.

Second, planting time

The planting time of Cymbidium is not limited by season, and the specific sowing time is determined by the seed ripening time.

Third, sowing method

1. In order to fully soften the endosperm and seed coat, the selected seeds were soaked in about 40 ℃ for about 30 hours before entering the soil. The treated seeds produce radicles in about 17-20 days.

2. Choose a container that is breathable and easy to drain, and wooden cases are recommended. Sawdust and river sand can be selected for preliminary planting. Here we will explain the way of river sand in detail. Choose fine sand, wash and disinfect, spread it in a container, put the germination eyes of the seeds down on the sand surface at an interval of about four centimeters, and spread a layer of fine sand on top, not too thick, as thin as a layer.

3. The use of river sand has a large planting gap and strong water permeability. if the basin surface is found to be dry, it should be sprayed or watered. Don't water too much, as long as the humidity reaches 40% and the temperature ranges from 18 ℃ to 25 ℃.

When the climatic conditions are created, it will take about a month or so for cotyledons to grow.

IV. Management of seeds after emergence

After the seeds grow out of the seedlings, it is necessary to divide the pots, choose a flowerpot with good air permeability, cover the bottom with about 5 cm of soil, and put the seedlings on. It is best to water the seedlings with spraying in the early stage, which can not only increase humidity, but also prevent excessive water from scouring the seed seedlings. Leave it in a semi-overcast place for a few days.
