The yield of garlic per mu is generally 1,000 to 1,250 kilograms.
The yield of garlic per mu is generally 2,000 to 2,500 kilograms. The specific yield varies depending on climate, soil quality, cultivation technology, etc. For example, with reasonable planting density and scientific field management, the yield per mu can reach 3,000 to 4,000 kilograms. However, if In years with unfavorable climate or serious pests and diseases, the yield may be less than 2,000 kilograms. In addition, cultivated varieties will also affect the yield per mu of garlic. Varieties that mainly produce garlic are definitely higher than varieties that mainly produce garlic sprouts.
If you want to increase the yield of garlic, you can choose the sowing time from the end of September to the beginning of October. When the garlic seedlings emerge, they should be properly watered and covered with soil. When the garlic seedlings emerge for the first time, you can combine watering with 20 acres per mu. Kilograms of sulfuric acid, insulation, ventilation and other work must be done when planting in greenhouses.
Notes on growing garlic:
1. Seed selection
The first step is to choose garlic seeds, which are actually the garlic cloves we often eat. Garlic cloves must be free of diseases and insect pests. After selecting the garlic cloves, the next step is to fertilize and prepare the soil.
2. Fertilization
Apply fertilizer before soil preparation. The fertilizer can be fully decomposed farmyard manure plus appropriate amount of fertilizer. After spreading the fertilizer, plow the soil deeply, usually about 30 cm. , turn the soil and dry it for about half a month. Plow the ground as early as possible to sow seeds as early as possible. Generally, planting should be done around the autumnal equinox. This will help garlic sprout and grow roots, which will help it survive the winter. After drying for half a month, the soil is leveled and the border is 120-140 centimeters wide, and garlic can be sown. After planting garlic, water it once to help the garlic germinate.
3. Close planting
Garlic must be planted in a reasonable and dense manner. Generally, the spacing between plants is between 10 and 12 cm, the spacing between rows is between 15 and 20 cm, and the depth is about 6 cm. Conducive to sprouting and growth of garlic. After garlic emerges, foliar fertilizers and fungicides should be sprayed in a timely manner to prevent garlic from developing pests and diseases while increasing yields.
4. Watering
Watering again after the garlic emerges, combined with hoeing, can promote the growth of the garlic root system. Before the arrival of the light snow season, it is usually watered 2-3 times, combined with hoeing, and sprinkled with wheat bran to protect garlic from overwintering safely.
5. Irrigation
In the second year before and after the hibernation, the ground temperature and underground temperature rise. At this time, the wheat bran can be removed for top dressing and irrigation, which can promote the growth of garlic. Garlic loves water. Generally, when there is dry soil on the surface, watering should be combined with hoeing. As the garlic grows, the amount of watering and top dressing should be gradually increased.
6. Top dressing and irrigation
When garlic grows garlic sprouts, the amount of water and fertilizer required increases at this time. At this time, top dressing and irrigation should be combined, but within three days of harvesting garlic sprouts Stop irrigation beforehand to facilitate bolting work. After the bolting work is completed, irrigation can be carried out according to the moisture content of the soil, but watering should be stopped 12 days after bolting. Stopping watering at this time can make the garlic grow more compact and improve its quality.
7. Prevention of pests and diseases
In addition to adequate water during planting, garlic must also prevent the occurrence of pests and diseases. Common pests and diseases include leaf blight, gray mold, grubs, etc. , we should focus on prevention and combine prevention with treatment.
