Garlic plan time and method
First, planting time
1, August to October
It is recommended to plant in autumn between August and October in the southern region.
2. March to April
In the north, it is planted in March and April in spring.
Second, the planting method
1, select improved varieties.
The selection of garlic seeds requires white, no red tendons, no scars, no saccharification and no smooth skin. Attention should be paid to the size of seeds, which is one of the key factors for high yield of garlic. Generally speaking, the size and weight of garlic seeds are about 5kg.
Step 2 sow at the right time
Garlic is a cold-loving crop, which has the characteristics of natural dormancy. Premature sowing, because it is still in dormancy, will slowly emerge. After the emergence of garlic seedlings, due to the high temperature in the early stage, they grow too fast before winter, and their cold resistance will be greatly weakened. However, after sowing, the nutrient accumulation of seedlings will be too little, which will shorten the growth period of garlic stems and leaves and affect the quality of garlic. Therefore, it is particularly important to choose suitable sowing materials.
3. Planting density
When sowing, try to choose larger garlic cloves as seeds, which can fully ensure the nutrient absorption of garlic and is beneficial to the growth and development of garlic. Generally speaking, 5g garlic cloves can be selected as seeds, and the planting density is kept at about 33,000 plants per mu.
4, soil preparation and sowing
In order to achieve high quality and high yield of garlic, base fertilizer must be applied when planting. In addition, you can choose a high ridge with the height of 15 cm every three beds, which is convenient for water retaining. After sowing garlic cloves, soil preparation should be done in time, ditches should be filled, and then roots should be watered to prevent garlic cloves from being pushed out of the ground when they take root and sprout.
Matters needing attention in planting garlic
1, water
Watering garlic after emergence and weeding can promote the growth of garlic root system. Before the arrival of the light snow solar term, garlic is usually watered for 2-3 times and combined with hoeing, and wheat bran is sprinkled to protect garlic from wintering safely.
2. Irrigation
In the second year, the ground temperature and underground temperature increased before and after the shock. At this time, wheat bran can be removed for topdressing irrigation, which can promote the growth of garlic. Garlic likes water. Generally, when there is dry soil on the surface, it should be watered in combination with hoeing, and the watering amount and topdressing should be gradually increased with the growth of garlic.
3. Top dressing and irrigation
When garlic seedlings grow, the demand for water and fertilizer increases. At this time, irrigation should be combined with topdressing, but irrigation should be stopped three days before garlic bolting to facilitate bolting. Irrigation can be carried out according to soil water content after bolting, but watering should be stopped after bolting 12 days. Stopping watering at this time can make garlic grow more compact and improve its quality.
4. Prevention of pests and diseases
Garlic needs a lot of water in the planting process, but also to prevent the occurrence of pests and diseases. Common diseases and insect pests include leaf blight, gray mold, grubs and so on. Prevention first, prevent combination.
