Today, it has entered a three-day sky. In recent days, many areas have been torrential rains. Many crops will be damaged in the ground. The crops that are affected are not only beans, corn, etc., but also peaches, pears, and plums. Grapes and other fruit trees. Fruit trees such as pears, peaches, and grapes are in the peak of summer growth, the fruit is rapidly expanding, and the autumn shoots are prolonged. When the fruit trees are hot and dry, there will be drought damage, and when the rainstorms continue, there will be damages, and such weather It is also prone to serious pests and diseases. So how should fruit trees be managed in July?
How to manage fruit trees in July? These three main points are worth collecting!
1. Timely increase fertilizer to supplement tree nutrition and balance tree potential.
(1) Topdressing under the tree. Pay attention to nitrogen and phosphorus, potassium fertilizer and various micro-fertilizers. According to the age of the tree, the tree potential, the amount of the fertilizer and the amount of fertilizer applied this year, the plant can apply 1 kg of potassium humic acid or special compound fertilizer of humic acid fruit tree. -3 kg, applied through a tree hole or an annular ditch, watered after fertilization.
(2) Foliar spray fertilizer. In particular, trees with a large number of results and weak trees are sprayed once every half month or so and can be mixed with other fungicides and insecticides.
(3) The trunk is painted. The fruit branches are dry coated with amino acid micro-fertilizer, which can promote fruit enlargement. Use quick-mixing boromagnesium-zinc-zinc-calcium-high-concentration hydrogen-based acid fertilizer 2-3 times solution, and apply 50-60 cm of brush ring on the smooth parts of apple, pear, peach, grape and other branches to ensure nutrient supply. It can also prevent the tree from taking a long time. Especially for trees with many results and weak growth, it is most beneficial. It can also control the occurrence of yellow leaf disease and lobular disease. It is usually applied once every 10-15 days.

2. Do a good job of summer pruning and adjust the tree potential.
For the pear tree, it is necessary to twist the shoots on the back, and to remove the dense branches, and the temporary long branches are softened, but the new branches of the pears are brittle, and the treatment is strictly prevented from breaking, and the softening of the branches is repeated and the angle is changed as much as possible. level. The branches on the back of the peach are about 30 centimeters long, and when the branches are about 50 centimeters long, they are tender and pointed. Appropriately remove branches and branches, and partially over-close branches to ventilate and transmit light. The 1-2 year old erect branches are twisted from the base to smooth the growth potential and promote flower bud formation. The grape shoots are topped, and the sub-tips below the ear are removed. The tops of the ears are 1-2 leaves and the tops are repeatedly topped. The tops of the branches are left with 1-2 pairs of tips. Each time, 3-6 leaves are topped, and the new vines are tied in time. It is evenly distributed on the frame surface, and the tendrils are removed in time to save nutrients.
3, pay attention to prevent disasters
In this season's disasters, attention should be paid to hail disasters, smuts, droughts, etc. caused by bad weather. In addition, it is necessary to do a good job in the prevention and control of pests and diseases.
In the event of a hailstorm, it is necessary to remove the unbreakable rotten fruit in time, cut off the cracked bark, and trim the edges. Spray fungicides and foliar fertilizers in time to prevent infection of infected parts, increase nutrient supply, and promote healing of wounds. Apply the drug to the injured bark to prevent infection with the rot.
If there is continuous high temperature and drought, it is necessary to pay attention to timely irrigation to prevent drought. If there is continuous heavy rain, pay attention to drainage, especially the fruit trees that are afraid of cockroaches such as peach trees, pay more attention to flood control. In addition, it is necessary to control the long autumn shoots, the orchard covering grass, the prevention of fruit cracking, grass and weeding.
