Garlic is a vegetable with a good fertilizer. It needs a lot of fertilizer. When the amount of nutrient absorption is 100%, the amount of potassium absorbed is 95%, the amount of calcium absorbed is 75%, and the amount of phosphorus absorbed is 35%. For each 10,000 kg of garlic, it is necessary to absorb 4.5 kg - 5.0 kg of nitrogen, 1.1 kg - 1.3 kg of phosphorus, and 4.1 kg - 4.7 kg of potassium.
The absorption of nutrients by garlic is consistent with the growth period. The seedling stage of garlic mainly depends on the nutrients stored in the garlic petals, and the absorption of the three elements of nutrients is very small. With the growth of seedlings, the differentiation of new flower buds and buds, the absorption of nutrients gradually increases, when convulsions begin, When the scale buds rapidly expand, the nutrient uptake increases rapidly and reaches a peak; in the late stage of squamous bud enlargement, the stems and leaves gradually dry up, the roots age and the nutrient absorption capacity is weakened.
Garlic particularly likes organic fertilizers, and the application of organic fertilizers can significantly increase the commodity rate of garlic heads. The autumn-sown garlic is applied with 5 to 7 square meters of high-quality ring fertilizer per acre, 20 kg to 30 kg of diammonium phosphate, 20 kg to 30 kg of potassium sulfate, or a three-element compound fertilizer per acre based on the application of organic fertilizer. -15-15) 30 kg - 50 kg. In the second year of Spring, when it returns to green, it starts to topdress. It is usually divided into 3 times - 4 times. 10 to 15 days before the rotten garlic mother combined with watering for topdressing, 50 kg to 100 kg per mu of cake fertilizer. 5 days - 7 days after the application of pumping fertilizer, 20 kg - 30 kg of ammonium sulfate per acre, 15 kg - 20 kg of potassium sulfate. When the garlic cloves begin to differentiate and the garlic stalks accelerate growth, the garlic stalks are fertilized, and the manure per acre is 1000 kg-1500 kg. After the garlic is harvested, the garlic enters the expansion period, and the urea is applied 10 kg to 20 kg per mu. Total 1 | <First <Prev 1 Next> Last> |
