Asparagus Seedling raising in early Autumn and late Autumn points for attention in different Autumn asparagus Seedling

Asparagus seedling

1. Raise seedlings in early autumn. To raise seedlings in early autumn, because the daytime temperature in early autumn is still very high, it is still necessary to cover the border with 2-3cm straw after sowing. When it dries up, spray water in time and remove the cover grass when the asparagus seedlings are unearthed. It is better to raise seedlings in early autumn. Plastic film cannot be covered on the border because of the high temperature during the day.

two。 Raise seedlings in late autumn. The time of raising asparagus seedlings in late autumn depends on the region, and it should be carried out no later than 30 murals 40 days before the first frost. if it is later, the seedlings will not grow enough and affect the seedlings to survive the winter. In late autumn, a small arch shed is generally added before the first frost, which can prolong the growth period of asparagus seedlings for 20ml for 30 days. Due to the high temperature during the day, the small arch shed should be ventilated at a temperature of 30 ℃. At night, the small arch shed is tightly covered and insulated. When the temperature is low, the asparagus seedlings in the small arch shed will appear freezing injury, wilting and death phenomenon, at this time enough overwintering water, the seedling age has reached more than 60 days, can survive the winter safely. In winter, the small arch shed can be retained or removed, which will not affect the survival rate of asparagus seedlings.

In general, asparagus seedlings in the seedling bed overwintering, should be slightly protected, can be sprinkled on the border with a layer of 4-5cm organic fertilizer, donkey, horse, sheep manure is more suitable. But do not let the seedling bed dry in winter, otherwise it is easy to freeze asparagus seedlings to death. Because asparagus can withstand the low temperature of-36 ℃, asparagus seedlings will not freeze to death as long as they do not dry or lose water in winter. No matter the seedling is raised in the protected field or in the open field, it can be planted when the seedling age reaches 60 murine 80 days and there are 4 aboveground stems.
