First, orchards with heavy frost damage and no harvest.
1. Leave more to protect the property. For orchards with heavy frost damage and insufficient effective flowering, fully retain and use side flowers, late flowers, weak flowers and axillary flower buds to set fruit, and after the young fruits are set, according to the amount of fruit set in the whole orchard, the distribution of fruit set, etc., each inflorescence can retain 2 fruits to make up for the lack of yield.
2. Accurate fruit setting. The injured orchard should carry out fine fruit thinning after the young fruit is set, select the normal fruit with a correct shape and a large fruit, and remove the weak, deformed, and frost ring fruit. When setting fruit, it is necessary to make full use of high-quality side flowers and underarm fruits to ensure economic output and efficiency.
3. Leaf raising and leaf preservation. At present, some fruit farmers in the hard-hit areas are beyond reproach for working to earn a living, but fruit trees are bound to be the "green bank" of our farmers' families, and a year of famine may be mistaken for the next year, and a year may kill trees. Hereby reminded: the harvest garden "early leaf disease, branch rot disease, red spider" and other diseases and insect pests must be prevented.
2. Orchards with mild and unfrozen frost damage.
1. Delay fruit thinning. In the event of a disaster, the apple orchard stops fruit thinning, and after the young fruits are obviously developed, it will be set at one time according to the principle of "removing the inferior and leaving the superior".
2. Spray repair. 7-10 days after the flowering, the first afterthimalization was sprayed in time, super 501000 times + 25% rich spring nitrile 3000 times + 12% mesobixin 2000 times + 4.5% high chlorine 1000 times + thousand red imidacloprid 2000 times + calcium magnesium lactate 800 times. Repair frozen cells, reduce frost damage losses, and promote the normal development of young fruits. At the same time, we should prevent diseases and insect pests and improve the ratio of good fruits.
3. Flush and apply fertilizer water. 40 days after flowering, especially within 16 days after flowering, is the vigorous division period of pulp cells, and strengthening management not only has a positive role in promoting the enlargement of the fruit, but also has important significance for strengthening the tree and overcoming the "big and small years". Xiehua posterior fruit rate of high "big year" tree, mu with "water 800 pounds + Hongrui amino acid flush fertilization 2 barrels + Australian Regen high nitrogen and high phosphorus 1 barrel", with a gun rush or hole irrigation roots, to promote the early formation of thick and bright green functional leaves, improve the division of young fruit cells and increase the number of cells, so that the tree potential to moderate robust transformation. According to the survey, about 15 days after the flowering, the weight of the single fruit increased by 85 grams compared with the control.
