Second, the cleaning of leaf surface due to flooding of the dirt formed on the leaf surface, which will reduce the photosynthesis of the leaves, and affect the fruit of the fruit enlargement. Therefore, at this time, clean the water with the spray gun and wash the dirt from the foliage.
Third, the entire park was disinfected due to broken branches and leaves. In this high temperature and high humidity, it is easy to make the virus infected and spread rapidly, such as anthrax, downy mildew, black pox and so on. Therefore, the fruit growers must be disinfected in a timely manner in the whole garden. The selection and concentration of pharmaceuticals are as follows:
1. Widespread fungicide: 80% of Dasheng M45600 times liquid.
2. An agent to deal with anthrax: 50% thiram 600 to 800 times, or 75% chlorothalonil 600 to 800 times, or 70% thiophanate-methyl 800 times.
3. Agents for controlling downy mildew: There are 25% metalaxyl 600 times (special effects), or 600 times 25% copper frost cream, or 58% Leidormil 600 to 800 times, or 78% Kebo powder 600 times. Or 70% Paterson rich 700 times.
4, against the blackpox disease agent: 40% Fuxing 8000 to 10000 times, or Fumei double 600 to 800 times, or 600 times Daisen Zinc. In the above pesticides, 0.2% of potassium dihydrogen phosphate can be added to improve disease resistance.
4. After removing the silt on the surface of loosen soil, in order to prompt the root system to quickly restore its metabolic capacity, the soil shall be treated with shallow loose soil. The loose soil should be fine and shallow in the loose soil. Do not dump soil in large quantities, as this will increase the degree of wilting of the foliage.
5. After cutting off dead leaves and leaves, they will leave a lot of broken leaves and leaves, and these dead branches should be cut off in time, so as not to consume the nutrients of the tree, which can reduce the breeding of diseases.
6. Concern over the weather After a heavy rain, suddenly it became clear and the temperature rose suddenly. In the event of such weather, the wilting of leaves and transpiration of the roots of the plant will cause imbalances in the water in the roots of the plants. Therefore, in the event of such weather, the fruit growers should do the following three things: first, spray water to cool down; second, remove obstructions around the garden to promote ventilation; third, shelter the sunlight on the shed, and shade the net to reduce the shed Internal temperature.
