First, do a good summer scissors
Pull branches in time and handle new shoots on the back to improve ventilation and light transmission, and reduce the occurrence of diseases.
Second, remove stagnant water
Improve irrigation and drainage facilities, repair drainage ditch at an early date, and remove accumulated water in time after heavy rain.
Third, timely fertilizer
The damaged orchards can timely apply additional nutrients on the basis of timely drainage and spray fertilizer (0.2-0.3% of potassium dihydrogen phosphate and 0.2-0.3% of urea or other high-quality foliar fertilizers). In the orchards with severe root damage, the spraying of leaves and amino acids on the trunk should be the main method to reduce the damage.
Fourth, timely clean garden
If diseases or insect pests occur in the orchard, the rain, water, and high temperature and humidity at this time, the most easily transmitted pathogens are also conducive to the occurrence and harm of pests such as Pyrosphaeridae, and the park must be cleared at any time. The diseased leaves, diseased branches, diseases and insects in the orchard will be cleared out of the park, buried or incinerated to reduce the number of pests and insects. The weeds in the orchard will be cleared in time to prevent cross-infection, and tree trays and inter-row cultivators will be carried out in due course.
Fifth, the correct application of pesticides
1. Spray the protective bactericide before the rain to prevent the occurrence of the disease. After the heavy rain, spray the systemic fungicide. If there is rain, you should pay attention to the spray before the rain.
2. In order to avoid phytotoxicity during high temperature season, choose high-quality, safe, and high-efficiency pesticides, and do not arbitrarily increase the multiple of medication.
3, do not spray Bordeaux before the rain: Bordeaux spray before the rain, after the rain washed off the lime on the fruit surface, but left the copper ions, it will stimulate the peel layer, produce phytotoxicity, the formation of fruit rust, affect Fruit appearance quality and product value.
4, do not spray in the drought, high temperature weather: General pesticide suitable temperature 20-30 °C, the maximum does not exceed 32 °C, so before 10 o'clock in the morning, 15 o'clock after the spraying is relatively safe, most pesticides in the weather is too Drought, spraying with high temperature, rapid evaporation of water, easy to increase the concentration of pesticides, coupled with fruit trees to absorb liquid fast, strong metabolism of physiological function, and relatively reduced resistance, and thus prone to phytotoxicity.
Six, prevention of burning
Due to the high temperature in summer, direct sun exposure on the fruit surface, the fruit surface local temperature up to 40 °C above, prone to sunburn. When the temperature is high at 1-3 pm and the sun is directly exposed to sunlight, spraying water to the positive side of the tree body, especially the southwest side of the canopy, can reduce the local temperature and avoid sunburn. Can also be fruit bagging, use a good quality fruit special paper bag for bagging, can avoid or reduce fruit sunburn. Orchard summer shear can not be too heavy, the number of branches should be based on the projected area under the tree, after the thinning flower shadow coefficient is generally maintained at about 30%, or prone to burning.
High temperature and rainy season fruit tree pest control
In the high temperature and rainy season, in order to avoid all kinds of diseases of fruit trees from happening madly and cause harm to the growth of fruit trees, it is recommended to adopt the following comprehensive prevention and control measures:
