Cultivation technology of four or six cloves of garlic covered with plastic film

1. Preparation

Choose the four or six petal white garlic varieties of Yongnian. When preparing the breaking petals, use large, neat, hard and free of bruises, no mildew, white color, and uniform size of garlic cloves.

2. Fertilizing the site

Encourage the return of straw to the field, which can not only reduce the amount of fertilizer applied, but also make the soil sullen and benefit garlic growth. Because garlic is covered with mulch for life, you should apply plantar fertilizer once. Specifically, apply 50-70 kg of high-quality compound fertilizer per mu, 250 kg of high-efficiency organic fertilizer or 5-10 cubic meters of decomposed farm manure, mix it with 1 kg of high-quality boron, magnesium, zinc, and iron, and then sprinkle it on the field and rotate it After sowing for 5-7 days, sow.

3. Sowing and spreading film

Garlic planting is generally planted in late September to early October, in time between autumn equinox and cold dew. Too late will cause the garlic seedlings to become weak and weak, which is not conducive to safe wintering. It is also easy to cause garlic to form a single-headed garlic that cannot produce garlic sprouts due to dysplasia during the wintering period, causing a reduction in production and affecting income. Before sowing, according to the row spacing of 20 cm, use three round ditches with a depth of about 6-8 cm, insert the garlic cloves vertically into the ditch at a distance of 7 cm from the plant and cover the soil, each row of seeds is 12 rows, and 3 channels can be covered Film (film width 90 cm, thickness 0.05 mm). After all the garlic seeds are planted, smooth the garlic. After pouring Mongolian water, spray the garlic herbicide to cover the film.

4. Garlic field management

Garlic generally breaks soil and sprouts 5 to 8 days after covering the film. Observe that the garlic sprout rate under the film is about 60% to 70%. You can use a homemade brush to push forward to help the garlic sprout break the film in time. In some cases, it can be broken manually. Membrane (Use a wire-made tool with a hook to hook out the garlic sprouts nested under the membrane). After the seedlings grow to a height of 20-25 cm, spray 100 grams of Jintailong per mu to 15 kg of water to lay a solid foundation for the safe wintering of garlic seedlings. Before wintering, antifreeze water should be poured, and antifreeze water should be poured for 4 to 5 days after the night freezes for 4 to 5 days. Choose sunny weather from 9 a.m. to 3 p.m.

Fifth, cover the double film

Choose the width of the film according to the width of the garlic plot (the width of the garlic film is 4.3 meters, 4 meters, 3, 5 meters, 3 meters, etc.), and prepare the coated utensils, which can be sawed with bamboo poles or branches. The 0.3-meter-long stick requires about 1,000 sticks per mu. Prepare some plastic ropes for 1 ～ 1.5 kg per mu. Before mulching, the garlic field should be inspected again. Garlic seedlings that did not come out of the membrane should be hooked out with wire hooks, and then continue to 3 ～ After 5 days, two layers of film are covered. When covering the double film, 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 at 2/3 of the bamboo pole. Into the ground, fix it while putting the film, fix 1 root at a distance of 1 meter, and then put it on the ground, and then take the soil and press it. Note that the width of the film and the overlapping part of the film should not be less than 0.3 meters. If it is lower than this value, it will be blown by the wind, which will affect the safety of garlic overwintering.

6. Spring Management

After the spring, the green water is poured back in the middle of March, and 10 to 15 kg of high-quality compound fertilizer is applied per mu with water. After that, it is repeated every 12 days. In mid-April, 1 kg of 48% phoxim plus 1.8% of avermectin 100 ml are added to prevent and control underground pests.

Seven, timely harvest

Stop watering 5 days before the garlic sprouts are harvested. After the garlic sprouts are harvested, water and add 10 kg of potassium fertilizer to promote the expansion of the garlic head and improve the quality. Garlic heads are harvested about 12 days after watering and fertilization, and dried and stored for 8 to 10 days after harvesting.
