In winter, temperatures are low, and most flower and tree pests enter hibernation through winter in various ways. This period is basically inactive and has little mobility. If the measures for winter prevention and control are effective, the occurrence and harm of pests and diseases in the coming year can be greatly reduced. The effect of doing more with less. Therefore, winter is a good season for pest control.
Clean up the pathogens (bacteria) or overwintering eggs of most of the flower tree pests in the nursery are wintering in the litter or weeds in the nursery. Therefore, in the winter, the litter and weeds in the nursery are completely cleared and destroyed to improve the sanitary conditions, which can greatly reduce various pests and diseases. This has a significant effect on the prevention and control of anthracnose, powdery mildew, rust, red spider, and moth in flowers and trees such as rose, rose, chrysanthemum, sea bream and willow.
Cut off pests and leaves combined with winter pruning, with emphasis on cutting off branches and leaves with pests and diseases, such as roses, roses and other insects on flowers and trees, poplars on willows, willows, and flower shrubs, cut off the branches and leaves of pests and diseases in time to clean up, transport Out of the nursery centralized destruction processing.
Winter plowing, deep plowing, winter plowing and deep plowing can cause mechanical damage to larvae, earthworms, eggs, etc. of subterranean pests such as earthworms, earthworms, and earthworms that are lurking in the soil. After exposure to the surface, they can be made into natural enemies such as birds. Food, if necessary, can also be taken manually. In addition, deep plowing can cause soil surface pathogens to be buried in deep soil layers. Pathogens in deep soil layers can be turned to the ground to destroy the pest's habitat.
The application of white coating to protect white stems not only effectively prevents the freezing damage of winter flowers and trees, improves the disease resistance of flowers and trees, but also destroys the overwintering sites of pests and insects, and plays a dual role of both preventing freezing and killing insects, especially killing Winter barks, crickets and other effects are better. Special attention should be paid to the fact that quicklime must be fully decomposed, otherwise it may cause burns when applied to flowers and trees.
Drug control Because of various dormant diseases in winter, it can be used to prevent and treat diseases and pests that are not easily controlled in the seasons. For example, the oil emulsion spraying with 50 times to 100 times liquid can control the scale insects, and spraying 1% Bordeaux mixture for 2 times to 3 times in late winter can play a good role in prevention and cure of diseases such as pear rust and rose black spot. .
Another important function of amino acids is to provide energy to the human body. Normally, a healthy body on a general diet will use carbohydrates as its main fuel, but when the main source is depleted due to strenuous exercise, protein and amino acids can be used as a last resort. Amino acids also play an important role in food taste. Protein doesn't have much taste, but each amino acid has its own taste, and combining them is one of the important factors that define the taste of food
