First, fertilization in autumn. 1. Base fertilizer: In the first ten days of September, the root growth peak is at the peak. The autumn base fertilizer can not only heal the root system due to fertilization, but also provide sufficient nutrients for the root system. Fertilization should not be too shallow, too concentrated, soil and fertilizer should be applied to the soil 40 to 60 cm deep. Each plant has 2535 kg of mixed fertilizer and 1 to 2 kg of special fertilizer for fruit trees. The amount of fruit used can be determined according to tree potential and yield. 2. Foliar fertilizer: Spray 0.3% to 0.5% potassium dihydrogen phosphate 2 to 3 times in late August, and spray 0.5% urea twice in September, at intervals of ten days. At the end of September, spray 50ppm gibberellin plus 0.5% urea once.
Second, autumn trimming. 1. Thinning: Eliminate the raising branches, floor branches, and back branches that prevent ventilation and light transmission, and cut off the sprouts of autumn germination. 2. Pulling branches: The best period for opening the branches is from August to September. Open the branches to 70-80 degrees, and have the value of raising.
Branches and branches open to 80 to 90 degrees. There should be two points when pulling the branches: one is that the base of the tree is less than 1 meter; the other is that the branches should be balanced, so that “flat, straight, and even†means “no circle, no bend, no sky, Do not drill the ground, do not overlap, and distribute evenly.
Third, pest control. 1. Deciduous disease: It can be prevented by using 10% polyoxymycin 1000 times liquid or hexaping 1500 times liquid. 2. Rotten fruit disease: 70% methyl thiophanate 700 times solution, or 30% compound carbendazim 500 times solution or 70% mancozeb 800 times solution can be used for prevention and treatment. 3. Red spider: can use 30% moth 螨 1500 times liquid, or 56% 螨 螨 300 300 300 300, or %7051 insecticide 2000 ~ 3000 times liquid control. 4. Caries: In the spawning period, 30% Tao Xiaoling EC 1000 times solution or 25% Huifeng Kike EC 1000 times solution can be used for prevention and control. 5. Gold-grained moth: Control with 25% chlorpyrifos 2000 times or 30% moth 1500 times or 4000 times.
Fourth, the autumn turned the orchard. On the one hand, the autumn fruit garden can deepen the soil plough layer, which is conducive to the vertical and horizontal growth of the root system and the expansion of the total root amount. On the other hand, the autumn orchard can destroy the place where the soil is wintering pests, and receives the pest control effect. Autumn is not to hurt the finger roots, the depth is: young trees 30 ~ 35 cm, the result of the tree 35 ~ 40 cm, in the forward direction for the autumn turn. Note that the good ground and the clay ground can only be straight forward in strips. When deep turning, avoid turning into rows, high between plants, and close to the tree plant to prevent the tree from becoming a water hole during the flood season, causing disasters.

Hormone:
A chemical substance produced in the body that controls and regulates the activity of certain cells or organs. Many hormones are secreted by special glands, such as thyroid hormone produced by the thyroid gland. Hormones are essential for every activity of life, including the processes of digestion, metabolism, growth, reproduction, and mood control. Many hormones, such as neurotransmitters, are active in more than one physical process.
Endocrine:
Pertaining to hormones and the glands that make and secrete them into the bloodstream through which they travel to affect distant organs. The endocrine sites include the hypothalamus, pituitary gland, pineal gland, thyroid, parathyroids, heart (which makes atrial-natriuretic peptide), the stomach and intestines, islets of Langerhans in the pancreas, the adrenal glands, the kidney (which makes renin, erythropoietin, and calcitriol), fat cells (which make leptin). the testes, the ovarian follicle (estrogens) and the corpus luteum in the ovary). Endocrine is as opposed to exocrine. (The exocrine glands include the salivary glands, sweat glands and glands within the gastrointestinal tract.)
