How to control winter flower and tree diseases and pests?

In winter, most of the flowers and trees stop growing or grow slowly, which is also a time when management is often neglected. In fact, winter is a critical period for pest control, and in order to make plants grow better next spring, winter should not be taken lightly in pest control.

Ensure that the growth environment of flowers and trees is clean and <>

When the temperature is below 0 °C, it is easy to cause the branches and leaves of flowers and trees to wither and rot, and breed bacteria, and when the weather warms up, these bacteria will cause harm to flowers and trees.

Therefore, after the arrival of winter, it is necessary to regularly clean up the plant growth environment, uproot the excess plants and take them out of the garden to bury or burn, so as to avoid the infection of healthy plants by diseased residues. In addition, while carrying out the clean-up work, the managers also need to disinfect themselves to prevent the spread of pests and diseases.

Clean up the <> of branches and flowers affected by pests and diseases

Winter pruning is an important part of flower management, and before the temperature drops, the staff should remove the branches and flowers affected by pests and diseases in time to prevent the occurrence of pests and diseases.

Before pruning, the staff should fully understand the relevant pruning knowledge of different seedlings, and grasp the symptoms of pests and diseases, so as to do a more comprehensive and effective job in pest control and pruning management.

Taking kumquat as an example, when the root of kumquat is rotten, it can be obvious that the branches and leaves of kumquat are yellow and withered.

Renovate the soil. Before transplanting flowers and trees, the soil should be renovated, mainly to eliminate germs and insect eggs in the soil in time. If there are too many insects in the soil, it is necessary to replace it with a new one, and before replacing it, the soil must be disinfected and nourished with charcoal ash, although this method is mainly suitable for smaller flower and tree planting plots.

For large-scale, wide-area seedling planting sites and natural forests, after the soil is renovated, there will be birds and insects that eat the pests that have been turned to the ground, and then the staff will clean the soil again and renovate it, and turn the missing pests and eggs into the ground, and these pests and eggs will die naturally due to insufficient air supply.

Apply the protective solution <> the branches

After the arrival of winter, in order to avoid the influence of low temperature and the damage of diseases and insects, lime and water can be used to make a protective solution and apply it to the branches of flowers and trees, which can play a certain protective role.

At the same time, when preparing the protective liquid, it is necessary to pay attention to the treatment details of the lime, and there can be no lumps in the protective liquid. When applying the appliance, it is important to wear protective tools (such as plastic gloves) because the high-calorie chemical reaction between lime and water can be caused by the contact between lime and water, and wearing protective tools can avoid burns.

Spraying or watering pollution-free chemical solution.

When carrying out pest control on flowers and trees, it is necessary to choose suitable pollution-free liquid for spraying or watering according to different seasons, and the applicable insecticides for different flowers and trees are also different.

For example, kumquat pest control body fluid monothiophosphonate and water should be mixed with 1 800 to form an insecticidal liquid, while magnolia insecticide liquid should be mixed with imidothion emulsifiable concentrate and water at a ratio of 1 1000.

Clean the flower bed on time, find branches and leaves with insects, cut them off in time, you can apply some drugs on the flowers and trees to prevent insects, and frequent turning of the soil can also prevent pests and diseases.

We can put the flowers and trees in a suitable growth environment, and carry out regular watering and fertilization, so that they can grow healthy and strong.

First, winter ploughing and deep ploughing. 2. Remove dead branches and leaves. 3. Cut off branches and leaves with diseases and insects. Fourth, white protection. 5. Fill frozen water in time. 6. Drug prevention and control.
