Many vegetable farmers in the drawing of cucumbers, some "cut corners", not to pull out the roots together, but cut off from the root of the cucumber. Some vegetable farmers even pulled out their roots. However, because the sheds were relatively dry when the garden was pulled out, only the main roots were pulled out, and most of the fibrous roots were left in the soil. When the cucumber is pulled out of the garden, it must bring out the roots. If the roots are not completely removed, it is easy to leave a curse and lay the hidden danger for the spread of the disease in the future. There are two major drawbacks to removing roots:
First, it is easy to leave a lot of bacteria in the cucumber plants have root diseases, if the root system is not completely removed, the pathogen will continue to stay in the soil, damage the next pod vegetables. Therefore, when the cucumber is pulled out, it is necessary to pull out all the roots. If the soil is dry, you can pour a little water before the garden to moisten the soil. If necessary, excavation can be taken to avoid leaving roots in the soil. In addition, it is best to mark the diseased plants before pulling out of the garden. After the garden is pulled out, the sickle should be treated with quick lime or liquid medicine to eliminate the germs completely.
The second is that it is easy to leave root knot nematodes in the roots in the soil. There is a large number of root knot nematodes attached to the cucumber roots. If the roots are not completely removed, they will remain in the soil and damage them. vegetables. Because cucumbers are a good time to eradicate root-knot nematodes at the time of gardening, they can use this opportunity to completely bring out root-knot nematodes attached to roots. To do this, when removing cucumbers, the root must be completely removed.
