How should cherry trees be fertilized in autumn? Here is an introduction to cherry fertilization methodsCherry tree fertilization can be carried out with reference to the following methods:
Cherry saplings under 3 years old are in the crown-expansion stage, with vigorous vegetative growth and a high demand for nitrogen, so nitrogen fertilizer should be the main type, supplemented with an appropriate amount of phosphate fertilizer to promote crown formation; young trees in the initial fruiting stage at 3-5 years old transition from vegetative growth to reproductive growth, and the number of flower buds increases, so attention should be paid to controlling nitrogen, increasing phosphorus, and supplementing potassium; trees over 6 years old enter the full fruiting stage, and the amount of fertilizer applied should be increased, with more potassium fertilizer supplemented.
1. Cherry trees should be given base fertilizer in autumn
1. Fertilization time The best time for autumn base fertilizer application is September-October, and earlier application is preferable.
2. Selection of fertilizer types: Mainly high-quality decomposed farmyard manure, pig and cattle barn manure, and other organic fertilizers, with an appropriate amount of compound fertilizer or phosphate fertilizer added.
3. Cherry tree fertilization method: When backfilling, first place 20 cm of crop straw at the bottom of the ditch, cover it with 20 cm of soil, then mix the fertilizer and soil evenly and apply it into the ditch. The organic fertilizer application layer is generally within the 15-40 cm soil layer.
4. Fertilization amount Autumn base fertilizer is generally applied in combination with hole expansion. Farmyard manure or pig and cattle barn manure: 50 grams per young tree, 100 kg per tree in the full fruiting stage; pure chicken manure: 10 grams per young tree, 30 kg per tree in the full fruiting stage; cake fertilizer: 15 grams per young tree, 30 kg per tree in the full fruiting stage.
2. Spray foliar fertilizer on cherry trees during the leaf-fall period
1. Best spraying time: In late autumn, one week before the cherry leaves fall, foliar fertilizer should be sprayed. The spraying time should not be too early or too late. Spraying too early may cause new shoots to sprout or burn the leaves due to excessively high urea concentration; spraying too late means the leaves fall before the nitrogen is absorbed by the leaves and transported into the tree.
2. Best spraying concentration: In order to increase the accumulation and concentration of nutrients in the cherry tree, 0.5% urea should be sprayed on the leaves.
