Pest control
1. Cut off powdery mildew and leaf roller moth, concentrated burning, severe spraying 15% Triadimefon 1500 times.
2. Scrape rot, rosy ring disease, and rough skin disease. Bridge or foot joints in large branches of branches.
3. When the leaf miner and leaf roller moth are seriously damaged, 25% diflubenzuron No. 3 suspension agent 2000 times solution or BT emulsion is used for control.
4. Main oil ring, control crawling pests on the tree.
5. Spray 10% imidacloprid WP 2000 times solution or 48% LS 1000 times to control various aphids and to cure other pests.
Underground management
1. Apply fertilizer and water before flowering.
2. Level the orchard, protect the cultivator, and the depth of cultivator is 6-7 cm.
Tree Management
1. Cut flowers before flowering. In the spring flower buds germinate after flowering, before the flower buds can be distinguished on the basis of the premise of the sooner the better, too late nutrient consumption is large, the role is not obvious. Red Fuji apple pre-flower shear work: the extension of the outer branch is a string of flower buds, according to the diameter from the base of the first inflorescence at the cluster of flowering branches determine the number of inflorescence, less than 3 mm in diameter of the string of flowering branches removed, diameter In 3 ~ 5 mm, 1 ~ 2 inflorescences are retracted, 3 ~ 4 inflorescences with diameters of 5 ~ 7 mm are retracted, and 5 ~ 7 inflorescences with diameters of more than 7 mm are retracted; peripheral extensions are The buds of the leaf buds are about 30 centimeters long. The branches are moderately strong and should not be cut until they are separated.
2. The tree pulls the branch open angle.
3. The saplings are put on branches in multiple rings or eye wounds.
4. Prepare the fistula and set up the hive.
mid-April
Pest control
1. Severe powdery mildew, spraying 0.3-0.5 Baume degree lime sulfur, or 80% of Dasong M-45 WP 800 times, or 15% Triadimefon 1500 times for control, and other diseases.
2. Spray 0.1% to 0.2% zinc sulfate solution to prevent lobular disease.
3. Flowering spray 400 to 600 times fluid, prevention and control of apple mold heart disease.
4. Manually kill, trap and kill beetles.
5. Continue to cure rot, ringworm, and rough skin.
Tree Management
1. Collect pollen during the big balloon period and dry it. Prior to flowering of the main cultivar, bell-flowers containing medlars were collected from appropriate pollinated varieties and taken to the room. Hold each flower in both hands and rub the two flowers to make the anthers fall off. After the anthers are unplugged, pick out the filaments, petals, etc., and dry them indoors. The collected anthers are spread on a thin layer of paper, placed on a table or wooden rack, and stirred several times to accelerate the loose powder. Be careful not to expose to sunlight.
2. Thinning flowers. When implementing this measure, attention must be paid to the following: First, there should be a strong tree vigor and full flower buds. Second, the central flowers left after flowering are all subject to artificial pollination. Third, it can only be applied in gardens where the fruit setting rate is high and the weather conditions during the flowering period are stable.
3. The early flowering orchard releases wall bees.
4. Artificially assisted pollination. The dot method is commonly used, but it can also be used.
The point method is to add the dried unwashed pollen powder with about 3 times fine talc or fine starch as the filling material, and mix it for use. The mixed pollen is put into a vial, and the pollinator takes a paper stick wrapped in an old newspaper as a pollinator, and grinds one end of the plush for powdering. Use a pollinator to take pollen, point on the stigma that should be pollinating the flowers, and spend 1 to 5 to 7 flowers. At the time of pollination, the number of pollinated flowers per tree was roughly determined based on how much the pollinated tree should bloom and the expected level of yield. For trees with less blooming, all open flowers in each inflorescence should be taught; for trees with more blossoms, they can be divided for inflorescence, and each inflorescence is given 2 to 3 flowers.
The dusting method uses 100 times pollen (filler is talc powder) placed in an electric duster and uniformly sprays around the tree. In the absence of a duster, it is also possible to place the pollen with the filler in a 2- or 3-layer gauze bag, tie it with a rope, and tie it to the long gill, holding it upright in the crown or tree shrew. Beat the dragonfly and pollen the pollen from the gauze bag to pollinate it.
5. Spray 250 times borax or boric acid at full bloom.
Late April
Pest control
1. Severe powdery mildew, continue to control.
2. Manually kill, trap and kill beetles.
3. Spray 80% carbendazim 1500-2000 times or 70% thiophanate-methyl 700-900 times to prevent ringworm and anthrax.
4. Scrape rot, rosy ring disease, and rough skin disease.
5. Spray 10% imidacloprid WP 2000 times solution or 48% LS 1000 times to control various aphids and to cure other pests.
6. Bundle the plastic film at the base of the trunk 40 centimeters from the ground to form an inverted trumpet shape to prevent pests from getting on the tree.
Tree Management
1. The main girdling of young saplings that need to increase fruit setting rate and control of prosperous growth should be carried out 5 days after flowering to flowering.
2. Marshal is the first time that the main ring of the breed is engraved.
3. Bridging the site of excision and large patches of rot that had poor healing during the previous year.
