Ice vegetables, also known as ice grass, are covered with ice crystals, just like a layer of small ice beads. Touch it with your hand, it's cold, it tastes slightly salty and cool, and it's very delicious. Iced vegetables are light-loving, drought-tolerant and waterlogging-tolerant, and have strong growth ability, and belong to relatively high-yield vegetables. The seeds of frozen vegetables are very small and hard, and their water absorption capacity is poor. Before planting, soak the seeds in warm water of about 30 degrees for about 5 hours.
It is not easy to fish seeds directly by hand. You can pour the soaked seeds directly on the towel with gauze or towel, and then clean them to sow. Frozen vegetables have small seeds and weak soil arching ability. The soil for planting frozen vegetables should be soft, breathable and moist. If the soil is hard, easy to harden and has poor air permeability, the seeds of frozen vegetables will not emerge, and even lead to the seeds rotting in the soil.
Precautions for sowing
Apply a layer of organic fertilizer on the soil and mix the fertilizer and soil evenly for several times. Beat some clods soft and you can sow. The sowing method is selected, and water is poured first. Be sure to water it more thoroughly, let the water seep into the ground slowly, and sow it as soon as there is no water left after the water seeps down.
The key step to determine the emergence of frozen vegetables is to cover the soil after sowing. Cover the frozen vegetables with soil sieve method, and cover the frozen vegetables with semi-dry fine soil with a thickness of not more than 0.5 cm. The temperature of sowing frozen vegetables is kept at about 20 degrees, and seedlings can emerge in about 10 days. Management after emergence is very simple, just water it when it is wet or dry.
