The cultivation of garlic seedlings requires five key steps in selection processing, soil preparation, seeding methods, water fertilizer management and harvesting techniques。
Selection:
Choosing to be full of disease-free garlic petals as seed, with the exception of skin peeling, sowing 6-8 hours with fresh water. The garlic base is inserted down into the wet sandy soil, with a distance of 3-5 cm. A 30 per cent increase in the growth rate of processed garlic can be achieved by avoiding the use of chilled garlic petals to discourage growth activity。
2. Soil preparation:
The loose and fertile sandy sandy soil is best suited to the growth of garlic seedlings and is mixed with 5 kg of rotting organic fertilizer per square metre. Soil ph is controlled in the range of 6. 0-7. 0, with 20 centimetres of deep tillage followed by dirigidation, which needs to be flatened to allow for easy drainage. The pellets can be mixed with pearl rock at 3:1 to ensure drainage holes at the bottom of the container。
3. Sowing methods:
In the autumn, september-october or spring, march-april is the best planting period, and the processed garlic petals are inserted into the soil at a distance of 15 centimetres and 8 centimetres. The soil is 2-3 cm thick and is sowed immediately. The winter seeding needs to cover the membrane temperature, and the summer seeding should be accompanied by a sunnet to prevent sunstorms。
4. Fertilizer management:
The soil is wet without water before seeding, and sprays are used every three days. Diluted bean-bread water is followed when the seed is 5 cm high, and potassium nitrous phosphorus compound fertilizers are applied every two weeks in the medium term. The introduction of drip irrigation systems saves 40 per cent of water, and the rainy season requires timely drainage to prevent root causes。
5. Harvest techniques:
Garlic seed is collected as long as 20-25 cm and cut from 1 cm in the base with scissors. One third of the plant will continue to grow after collection in batches and will be frozen immediately after harvest. If seed is needed, the choice is to retain a strong plant until the flower is cut, and to dry it when the garlic matures。
In the process of planting, the soil can be improved with slag and periodically rotated to prevent endemic diseases. The cessation of fertilization and the reduction of water irrigation during the week preceding the harvest can increase the accumulation of garlic-flavoured substances. Household cultivation is recommended for the use of balconies, which can reduce pesticide use in conjunction with biological pest control nets. Maintaining a daily average of 6 hours of light and an ambient temperature of 15-25°c makes the garlic leaf thicker. The hydroponic method requires a daily replacement of nutrients and oxygen, suitable for the rapid production of sprouts。
