Improper management of asparagus before winter will cause the bamboo shoots to freeze to death, which will have a great impact on the yield and quality of the asparagus throughout the growing season. Here is a brief introduction to the precautions for the management of asparagus before winter:
Lightly slashing, increasing ground temperature with the onset of winter, the temperature will be lower and lower, in order to reduce water evaporation, increase ground temperature, should be shallow plan to promote root growth.
After cultivating the soil, the soil after the planing is buried in the planting ditch for soil cultivation. After the frozen water is poured, the last soil is completed, and the soil is generally about 15 cm high. This will not only help the asparagus safely overwinter, but also reduce the number of hollow bamboo shoots in the coming year.
Before the water is poured, before and after the winter, the last water is poured before the soil is frozen. This time, the watering is what the farmers often call “frozen waterâ€. "Frozen water" is based on the principle of "water before freezing, not water after freezing".
It is very beneficial to prevent winter drought, keep the soil moist, and protect the bamboo shoots safely for wintering. It is also beneficial to the extraction and growth of spring buds in the second year and reduce the hollowness of asparagus.
In the late autumn, the seedlings are managed in the winter before the asparagus seedlings are overwintered in the nursery. They should be slightly protected. A layer of 4-5 cm thick organic fertilizer can be sprinkled on the surface of the clam, especially the clams, horses and sheep manure.
