The latest winter asparagus field management techniques tutorial

As the weather gets colder and colder, we must also feel the coolness of winter. Now it is gradually entering winter, and many asparagus growers are also preparing for the overwintering of asparagus one after another. Although asparagus is resistant to low temperature, it will have a certain impact on the quality and yield of asparagus if it is not managed. So how to manage asparagus in winter? Today, the editor brought the asparagus winter field management method, let's have a look!

1. Clear the garden in time

Autumn is the season for harvesting asparagus. It is necessary to do a good job in clearing the garden in time after harvest. 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 of the field will be wasted and the yield and quality of the second year will be affected. And the stems and branches that do not wither should be well preserved to prevent the scale buds from being hurt, which will do some harm to the new stems and branches in the second year. When clearing the garden, you can't cut it with a knife, otherwise the knife will sprout again and consume nutrients in the field. After pulling out the withered stems and branches, take good treatment measures with some fallen leaves to clear out the countryside.

2. Disinfection and disease prevention

The work of clearing the garden is only a superficial work, and there are still many bacteria and eggs hidden in the fields, which will harm the growth of asparagus when the temperature picks up 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 have to do a good job of soil disinfection in time after the completion of the garden cleaning work. Although soil disinfection can not completely disinfect germs, it can also greatly reduce the number of bacteria. During soil disinfection, chlorothalonil and other agents can be used to spray and irrigate roots, and then spread an appropriate amount of carbofuran on the soil, which can effectively reduce the incidence of disease.

3. Water and fertilizer management

After disinfection in the garden, in order to ensure that asparagus can survive the winter successfully, we should strengthen the water and fertilizer management in the field. Fertilizer ditches can be dug on both sides of asparagus, mature farm manure and compound fertilizer can be used, and pay attention to the nutrition ratio of fertilizer. When applying fertilizer, it is necessary to avoid direct contact with fertilizer at the root of asparagus and prevent it from being burned by fertilizer. Water immediately after applying base fertilizer to promote the dissolution of fertilizer and make the soil fertile evenly. Let asparagus in the overwintering process of enough nutrients to support, improve the survival rate of asparagus overwintering.

4. Loosen the soil and weed

After fertilization and watering, loosen the soil and weed properly, enhance the soil moisture conservation capacity, improve the soil temperature and humidity, so that the soil and fertilizer are fully mixed. And loosening soil can effectively improve soil permeability, promote root growth and development, and make its nutrient absorption capacity stronger. Loosening the soil can be carried out with weeding work, the growth ability of weeds is very strong, if the weeds are not removed in time, most of the nutrients of asparagus will be taken away by them. So that asparagus can not grow normally. Weeding can be done manually, or chemical weeding can be carried out with herbicides such as chloroflurane.

The above is a brief introduction of asparagus field management methods in winter. Asparagus cultivation has different management methods in each season. Now after entering the 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.
