The garlic cultivation method for the purpose of cultivating garlic seedlings is similar to the method of producing garlic and garlic heads, the difference is that garlic seedlings are aimed at fast growth and stout, and the fertilizer applied is also different.
1. Mainly farm manure, improve soil fertility, in order to produce high-quality garlic seedlings. Before land preparation, 5,000 kilograms of decomposed farm manure are applied per mu, which can be mixed with insecticides or fungicides according to the occurrence of diseases and insect pests such as maggots and grubs.
2. Apply sufficient nitrogen fertilizer and potassium fertilizer to promote the rapid growth of garlic seedlings. Garlic seeds are garlic cloves, which contain more nutrients, before the motherhood, can rely on their own nutrition to grow, however, the production of garlic seedlings in order to produce more seedlings, you need to add more mineral nutrients according to the fat law of garlic, in order to promote garlic seedlings to grow stronger and higher.
Garlic in the seedling stage to absorb nitrogen fertilizer, followed by sulfur fertilizer and phosphate fertilizer, so according to soil fertility, can be applied urea 20 kg, potassium sulfate 10-20 kg, if the soil phosphorus deficiency is serious, you can also apply potassium sulfate type ternary compound fertilizer, or high nitrogen and high potassium fertilizer 40 kg as the bottom fertilizer, and farm manure at the same time into the soil.
If there is a large amount of human feces and urine, the amount of urea used can also be reduced, and the human feces and urine diluted by watering in the sowing line, the garlic seedlings grow thicker and greener, and the seedlings grow thicker.
3. Foliar fertilization is the mainstay after emergence. Some people advocate that the application of nitrogen fertilizer about 10 days after emergence is labor-intensive and uneconomical, and it is not as simple and effective as a seed fertilizer. After emergence, there is almost no need for topdressing, but foliar sprays of 0.2-0.5% urea and 0.2-0.3% potassium dihydrogen phosphate can be applied, which is not only fast, but also has good results.
Of course, the mother fat is strong, the larger the garlic clove, the better, the seed that is soaked and germinated emerges faster, the seedling grows more robustly, especially in the high temperature period, the garlic seedlings sown must be sown after low temperature germination, and after sowing, the ground needs to be covered with moisture and the air shade net shade cooling, in order to ensure the smooth emergence of seeds and seedlings grow in the right temperature environment.
Cultivating garlic seedlings needs to maintain high soil moisture, also need to prevent diseases and insect pests, and only by paying attention to the management of all aspects can we grow and produce thick garlic seedlings in the season when they are needed.
