If garlic is mainly harvested, 4000-5000 kg of decomposed manure, 60-80 kg of phosphorus nitrate and 30 kg of potassium nitrate are applied per mu. If garlic seedlings are mainly harvested, 2500-3000 kilograms of livestock manure should be applied to each mu of land; Or 5000 kg of garbage fertilizer +60-80 kg of nitrophosphate.

First, the best formula of garlic base fertilizer

1, sowing garlic in autumn

(1) Base fertilizer: 4000-5000 kg of decomposed manure, 60-80 kg of phosphorus nitrate and 30 kg of potassium nitrate are applied per mu.

(2) Topdressing: at the seedling stage of 3-4 leaves, when the height of the false stem is about 10cm, topdressing the decomposed fertilizer1000-1300kg per mu; When overwintering, apply 500 kilograms of garbage fertilizer per mu; After spring, when garlic roots begin to grow, 40-50 kilograms of nitrophosphate is applied to each mu of land; When garlic flower buds differentiate, apply 40 kilograms of potassium nitrate per mu; After bolting garlic, apply thin fertilizer or 30 kilograms of nitrophosphate per mu.

Step 2 sow garlic in spring

On the premise of applying sufficient basic fertilizer (similar to autumn sowing), after the seedlings are formed, apply 50- 100kg cake fertilizer or 30kg nitrophosphate per mu; When bolting garlic, 30 kg of nitrophosphate and 30 kg of potassium chloride were applied to each acre.

Step 3 eat garlic sprouts

(1) Base fertilizer: 2,500-3,000 kg of livestock manure per mu, or 5,000 kg of garbage manure and 60-80 kg of nitrophosphate per mu.

(2) Topdressing: after the garlic seedlings are fully grown, 65,438+0,000-65,438+0,500 kg of decomposed human manure or 30 kg of nitrophosphate are applied per mu; In the middle growth stage, 30 kg of nitrophosphate and 30 kg of potassium sulfate were applied to each mu of land; About 15 days before harvesting, apply 1000- 1500 kg of decomposed human excrement and urine per mu.

4. Fertilization method of base fertilizer

Generally, half of the organic fertilizer will be turned into the soil during land consolidation, and the other half will be ditched when sowing.

Second, garlic fertilizer is used too much. Can I still water my roots after burning them?

1. Garlic fertilizer can be watered if it is used too much, which can dilute the fertilizer to a certain extent. With the flow of water, some fertilizer can also be taken away.

2. Use 8.3ml of uranium foliar fertilizer per mu, dilute it with 30-40kg of water and spray it; If it is seedling stage, dilute 4.2ml of uranium foliar fertilizer with 30-40kg of water per mu and spray it.

3. If ammonia gas, nitrous acid gas and sulfur dioxide are poisoned due to excessive application of nitrogen fertilizer and organic fertilizer, ventilation should be strengthened immediately.

4. Spraying with 2-3g Bihu Lake diluted with water per mu can effectively reduce fertilizer damage.
