Three stages of fertilization in Gladiolus
The first stage: apply base fertilizer. Sufficient base fertilizer can promote the rapid growth of bulbs and shorten the flowering time p>
The second stage: topdressing once at 2-leaf stage, 4-leaf stage after emergence and after flower cutting. These three small stages are the key to the growth of gladiolus. As long as you spend it safely, you can grow healthily p>
The third stage: from August to September, during the rapid growth period of new balls, topdressing once. The seed ball grows rapidly and can reserve certain nutrients, which is more conducive to winter p>
What fertilizer does Gladiolus apply
Gladiolus is sensitive to the content of salt, fluorine and chlorine in the soil. It should be careful in the selection of fertilizer. Try not to use triphosphate, but can be replaced by other phosphate fertilizer to avoid leaf tip drying p>
When topdressing, you can choose root fertilizer or leaf fertilizer, which should be combined with watering to promote the fertilizer effect. Commonly used fertilizers include ammonium nitrate, potassium nitrate, calcium superphosphate, potassium dihydrogen phosphate, ammonium sulfate, potassium sulfate, urea, etc p>
Specific fertilization methods of Gladiolus
During the growth period, phosphorus fertilizer is the main fertilizer, supplemented by nitrogen fertilizer. At the seedling stage, apply fertilizer according to the three small stages of growth, about 5g per plant. Pay attention to mixing granular fertilizer into fertilizer and watering, which is more conducive to absorption p>
In the growth period of adult plants, the concentration of 1% potassium dihydrogen phosphate solution or neodendrin is used as Topdressing and spraying outside the root for 5 ~ 7 days p>
