Cultivation techniques of mulching for 46 cloves garlic

1. Seed preparation

Choose Yongnian four or six white garlic varieties. When preparing the seeds, choose large, neat, hard, no bruises, mildew, white, and uniform garlic cloves.

2. Soil preparation and fertilization

It is recommended to return straw to the field, which can reduce the amount of fertilizer applied, but also make the soil mellow and facilitate the growth of garlic. Because garlic is covered with plastic film for life, it is necessary to apply foot fertilizer once. Specifically, apply 50-70 kilograms of high-quality compound fertilizer, 250 kilograms of high-efficiency organic fertilizer, or 5-10 cubic meters of decomposed farm manure per mu, and mix it with 1 kilogram of high-quality boron, magnesium, zinc, and iron, and then sprinkle it on the field. After being placed for 5-7 days, sowing.

Three, sowing and filming

Garlic planting is generally planted from late September to early October, at the right time between the autumnal equinox and cold dew. Too late will cause the garlic seedlings to be weak and not conducive to safe overwintering, and it is also easy to cause the garlic to form a single garlic that cannot produce garlic sprouts due to poor growth during the overwintering period, which will reduce production and affect income. Before planting, use columbine to draw three trenches with a depth of about 6 to 8 cm according to the row spacing of 20 cm. Insert the garlic cloves into the trench and cover with soil at a distance of 7 cm. Each border has 12 rows and can cover 3 lanes. Membrane (film width is 90 cm, thickness is 0.05 mm). After all the garlic seeds are planted, level the garlic border. After pouring the masking water, spray the garlic herbicide and cover the film.

Fourth, garlic field management

Garlic usually begins to break the soil and sprout 5-8 days after covering the membrane. When observing the germination rate of garlic under the membrane is about 60%~70%, it can be pushed forward with a homemade brush to help the garlic sprout to break the membrane in a timely manner. Membrane (use a self-made tool with a hook to hook out the garlic buds nestled under the membrane). After the seedlings grow up to 20-25 cm in height, spray 100 grams of Jin Tailong per mu on 15 kg of water to lay a solid foundation for the safe overwintering of garlic seedlings. Antifreeze water should be poured before overwintering, and the antifreeze water should be watered after 4 to 5 consecutive days when the night is frozen and the day has disappeared. Choose fine weather from 9 am to 3 pm.

Five, cover double film

Choose the width of the film reasonably according to the width of the garlic plot (the width specifications of the garlic film are 4.3 meters, 4 meters, 3, 5 meters, 3 meters, etc.), and prepare the covering utensils, which can be sawed by bamboo poles or branches A 0.3-meter long stick requires about 1,000 sticks per mu. Prepare some plastic ropes for 1 to 1.5 kilograms per mu. Check the garlic field before covering the film. Use wire hooks to hook out the garlic seedlings that have not come out of the film. Then, in heavy snow, the temperature drops below 0°C for continuous 3~ Cover with two layers of film after 5 days. When covering the double film, you should choose to start after 9 a.m. when the weather is fine. Place the film on the ground and press it evenly on the film to fix it, and then use a plastic rope to tie the bamboo pole into 2/3 of the bamboo pole. Put the film into the ground and fix it at the same time, fix one at a distance of 1 meter until it is placed on the ground, and then take the soil and press it. Note that the width of the overlapped part of the membrane and the membrane should not be less than 0.3 meters. Below this value, it will be blown up by the wind and affect the safe overwintering of garlic.

Six, spring management

After the spring begins, water back to green water in mid-March, and apply 10-15 kg of high-quality compound fertilizer per mu with water. After that, it will be repeated every 12 days. In mid-April, 1 kg of 48% phoxim plus 100 ml of 1.8% abamectin will be used to control underground pests.

Seven, timely harvest

Stop watering the garlic sprouts 5 days before harvest. After the garlic sprouts are harvested, they should be watered and topdressed with 10 kg of potassium fertilizer to promote the enlargement of the garlic and improve the quality. Garlic is harvested about 12 days after watering and fertilization, and it is sorted and stored in the air for 8-10 days after harvest.
