Improper management of asparagus before winter will cause the shoots to freeze to death, which will have a great impact on the yield and quality of the asparagus throughout the growth period. Here is a brief introduction to the pre-winter management of asparagus:
Light hoeing to increase ground temperature As winter comes, the temperature will get lower and lower. In order to reduce water evaporation and increase ground temperature, shallow hoeing should be used to promote root growth.
Cultivating the soil by cultivating the soil by burying it in the planting ditch for soil cultivation. The last soil cultivation is completed after the freezing water is poured. Generally, the soil cultivation is about 15 cm high. This will not only help the asparagus to survive the winter safely, but also reduce the number of hollow bamboo shoots in the coming year.
Water before freezing before and after the beginning of winter, water for the last time before the soil is frozen. This watering is what farmers often call "freezing water". "Frozen water" is based on the principle of "watering the water before freezing, not watering after freezing". It is very beneficial to prevent winter drought, keep the soil moist, and protect the shoot buds to survive the winter safely. It is also beneficial to the spring buds in the second year. The spewing and growth of asparagus reduces the hollowness of asparagus.
The late autumn nursery seedlings are managed before winter. The asparagus seedlings will survive the winter in the seedling borders and should be slightly protected. A layer of 4 to 5 cm thick organic fertilizer can be sprinkled on the borders, especially donkey, horse, and sheep manure.
