Field management techniques of asparagus in winter

As the weather gradually became colder, everyone must have felt the coolness of winter. Now that winter is gradually entering, many asparagus growers are also preparing asparagus for winter. Although asparagus is cold-tolerant, it will affect the quality and yield of asparagus if it is not managed. So how should asparagus be managed in winter? Today's small series brings asparagus winter field management methods, let's take a look!

1. Clean up the garden in time

Autumn is the season for harvesting asparagus, and it is necessary to do a good job of clearing the garden in time after harvesting. If there are completely withered stems and branches in the field, they should be pulled out by hand in time, and those that are not completely withered should not be pulled out, otherwise the nutrition in the field will be wasted and the yield and quality of the next year will be affected. And there is no phenomenon of withered stems and branches to preserve intact, to prevent injury to the scale buds, the second year of new stems and branches have a certain harm. Do not cut with knife when clearing garden, otherwise the cut place will sprout again and consume field nutrients. After pulling out withered stems and branches, clear them with some fallen leaves and do a good job in the countryside.

2. Disinfection and disease prevention

Garden cleaning is only a superficial work, but there are still many germs and eggs hidden in the field, which will come out to harm the growth of asparagus when the temperature rises in spring. Therefore, in order to reduce the number of germs in the field and reduce the incidence of various diseases and insect pests, we should do a good job of soil disinfection in time after the completion of the garden cleaning work. Although soil disinfection cannot completely disinfect germs, it can also greatly reduce the number of germs. Chlorothalonil and other chemicals can be used to spray root irrigation when soil disinfection, and then spread appropriate amount of carbofuran on the soil, which can effectively reduce the incidence of disease.

3. Water and fertilizer management

In order to ensure asparagus can survive through winter successfully, we should strengthen the management of water and fertilizer in the field after cleaning and disinfection. Fertilization ditches can be dug on both sides of asparagus. Composted farm manure and compound fertilizer can be used as fertilizer. Pay attention to the nutrient ratio in fertilizer. When fertilizing, avoid direct contact with fertilizer at asparagus roots to prevent fertilizer burns. After applying base fertilizer, water immediately to promote the dissolution of fertilizer and make soil fertility uniform. so that asparagus can have enough nutrition and moisture support in the overwintering process, and the survival rate of asparagus in the overwintering process can be improved.

4, loose soil weeding

After fertilizing and watering, loosen soil and weed properly, enhance soil moisture preservation ability, improve soil temperature and humidity, and fully mix soil and fertilizer. Moreover, loosening soil can effectively improve soil permeability, promote root growth and development, and make its nutrient absorption capacity stronger. Loosening can be carried out in conjunction with weeding. Weeds grow very strongly. If weeds are not removed in time, most of the nutrients of asparagus will be taken away by them. This causes asparagus to fail to grow properly. Herbicides can be pulled manually, or chemical herbicides such as halothrin can be used.

The above is a brief introduction to asparagus winter field management methods, planting asparagus in each season there are different management methods. Now after entering winter, we must make preparations in all aspects to help asparagus survive the winter successfully, so that its yield and quality will not be affected.
