The temperature gradually decreases, and most of the flower seedlings will enter the wintering (or dormant) state in various ways. During this period, various pests and diseases were basically inactive and the mobility was small, which was a good season for pest control. Practice has proved that the effectiveness of winter prevention and control is directly related to the occurrence of pests and diseases in the following year. If the measures for prevention and control in winter are effective, the occurrence and harm of pests and diseases in the coming year can be greatly reduced, and the effect of getting twice the result with half the effort is obtained.
Cleaning up the nursery Most pathogens (bacteria) or wintering eggs of flower seedlings are wintering in the litter or weeds in the nursery, and then come out when the conditions are favorable in the coming year. Therefore, in the winter, the litter and weeds in the nursery are completely removed and destroyed, and the sanitary condition can be improved, which can greatly reduce various sources of pests and diseases. This has a significant effect on controlling anthracnose, powdery mildew, rust, red spider, moth, etc. of flowers such as rose, rose, chrysanthemum, jellyfish and willow.
Cutting off the leaves with pests and diseases Winter pruning is one of the important links in nursery management. Combined with winter pruning, it focuses on cutting off the branches and leaves with pests and diseases, such as the eggs on the flowers and trees of the rose, rose, etc., the scale insects on the leaves of poplar, willow and flower, and the cuts of the pests and leaves should be cleaned up in time, and the nursery will be destroyed and disposed of. .
Winter ploughing and deep ploughing of winter ploughing can cause mechanical damage to larvae, cockroaches, eggs, etc. of underground pests such as cockroaches, tigers, and cockroaches that are lurking in the soil. After being exposed to the surface, they can be smashed by natural enemies such as birds. Eat, if necessary, artificial killing. In addition, deep turning can bury the pathogens in the soil surface into the deep soil layer, and the pathogens in the deep soil layer are turned to the ground, destroying the suitable environment of the pests and diseases, and effectively controlling the occurrence of pests and diseases.
Whitening protection Whitening of branches can not only effectively prevent the freezing damage of winter flowers and trees, improve the disease resistance of flowers and trees, but also destroy the wintering places of pests and diseases, and play the dual role of preventing freezing and killing insects. In particular, it is better for the mites and mites that overwinter in the bark. It is important to note that quicklime must be fully digested, otherwise it may cause burns on the branches of flowers and trees.
Drug control Because winter, various pests and diseases are mostly dormant, winter pest control can be used for those pests that are difficult to control in the season. For example, 50-100 times liquid oil emulsion can be sprayed to prevent and control scale insects, and spraying 1% Bordeaux mixture 2 to 3 times in late winter can play a good role in controlling various diseases such as pear rust and rose black spot.
