The planting area of ​​garlic has been continuously increasing with the increase of price. The planting area of ​​garlic in China has reached 700,000 hectares, accounting for more than 60% of the global garlic planting area. The output accounts for 70% of the global production. The main production bases are concentrated in Shandong, Henan, Jiangxi, Guangxi, Anhui and other provinces. Garlic film mulching technology can cultivate strong seedlings, early maturity and increase yield. This technology has been widely used in major planting bases and is widely used by farmers.

Garlic is drought-tolerant but likes fertilizer water. When the fertilizer is sufficient, the yield can be greatly improved. Especially when garlic is watered frequently during the expansion period, watering is a key and labor-intensive task in garlic management. Good irrigation measures can satisfy The need for garlic to grow can save water, reduce pests and diseases, and save labor. With the popularization of drip irrigation technology and facilities in recent years, drip irrigation technology is also increasingly applied to production. Huinong.com Xiaobian today introduced a technical point of cultivation of drip irrigation with garlic film.

First, variety selection and sowing date

Regarding the variety, each planting area has its own main varieties, and the related varieties cultivation and promotion mechanisms are relatively mature. Choosing suitable local cultivars and selecting products according to the market are two basic principles; the sowing date is slightly different across the country. Generally, it is in the middle to late September to the beginning of October. The specific sowing date is determined by the daily average temperature of 17-20 °C. All localities can make reasonable arrangements according to this standard. The sowing date can ensure that the garlic can be 5 leaves and one heart overwinter. purpose.

Second, land selection and land preparation

1. Site selection

Garlic is more resistant to heavy sputum, but the garlic that is not heavy is growing well, with less pests and diseases, and high yield. Therefore, when selecting plots, it is preferred to select plots that have not been planted with garlic for planting. Garlic is not strict with soil requirements, and all kinds of soil can grow. It is best to use fertile sandy loam. The plots for planting garlic are best flat and easy to fill and drain. Avoid picking up plots of green onions before, and the pests and diseases will be more serious and the growth will be poor.

2, soil preparation

The growth of garlic requires deep and loose soil layers. Generally, the depth of cultivation is more than 25 cm. The soil is finely divided and the surface is flat. Generally, 2000-3000 kg of organic fertilizer and 40 kg of ternary compound fertilizer can be applied per mu, and 15 kg of urea, 20 kg of potassium sulfate, and 50 kg of superphosphate can be applied. The whole land is smashed according to the width of 80cm, and the surface is required to be flat to facilitate laying the mulch and preventing weeds.

Third, sowing

The planting distance is 20cm, the plant spacing is 8-10cm, and each row is planted in four rows. The ditch can be used for ditching and sowing. The ditch should be deep and shallow, and the garlic should be erected in the ditch. When planting, the dorsoventral connection of the petal should be made. Parallel to the ditch, so that the leaves of the garlic sprouts are perpendicular to the row, so that the garlic leaves receive more sunlight without shading. The specific cultivation mode is shown in the schematic.

Fourth, pipe coating film

After the garlic is planted, a drip tape is placed in the middle of the crucible, and then the herbicide is sprayed to prevent weeds and cover the mulch. For herbicides, please refer to the following: 48% of the cable oil per acre 200 ml or 150 ml of Duer, 50 L of water; or 80-100 ml of fruit or 200 ml of Shi Tian, ​​100 water

V. Water and fertilizer management

Garlic usually emerges in 5-7 days, 10-12 days in the seedlings. If the bottom is sufficient, the soil is not too dry, and the first drip irrigation can be carried out after the seedlings. A second dropper can then be taken before winter to promote safe wintering. When the seedlings turn green in the spring, the green water should be poured back in time, and 10 kg of urea can be applied with the water droplets. After returning to green, garlic enters a vigorous growth period. When the sunshine is greater than 13h, the underground bulbs differentiate and grow flower buds differentiate. The tip of 1~4 leaves begins to turn yellow, and the roots begin to retreat. At this time, the mother water should be poured back and the fertilizer should be added in time. It can be combined with foliar fertilization to shorten the yellow leaf time.

After the garlic enters the pumping period, the water demand should be increased. The water should be timely watered according to the grievances. The pumping period is planned to start entering the period of demanding fertilizer. The urea can be applied 15kg and potassium sulfate 5-10kg. Stop watering three days before picking. After harvesting, it is planned to enter the late stage of garlic expansion, which is also a key period for the formation of yield. At this time, it is necessary to keep the soil moist and promote the expansion of the garlic head. It is prone to premature aging in the later stage. It can apply 10kg of urea with water droplets and timely fertilize with foliar fertilization. Ensure that garlic is of high yield and quality.

Sixth, harvest

About 20 days after picking, the garlic leaves withered, the pseudo stems are loose, and the nutrition begins to transfer to the bulbs. It is time to harvest the garlic. Watering one week before harvesting, aging the garlic, improving the storage of the garlic, it is also convenient. Garlic, after harvest, cover the garlic with stems and leaves to cool the field, making the fake stem soft. The dried garlic can be processed into bags for storage or sold directly.

7. Pest control

In the case of re-application of organic fertilizer and scientific management, garlic will reduce pests and diseases. With the heavy disease and management of extensive pests and diseases will be more serious, garlic pest control is also an essential management. The prevention and control of garlic pests and diseases should follow the principle of prevention and prevention, and achieve the first treatment without disease.

1 Before winter, the two-leaf and one-heart period can be sprayed with 40% dimethoate 1000 times liquid to control the leaf miner once; the garlic is found in the field, and the trichlorfon or 50% phoxim emulsion is used in 500~1 000 times. Spraying; for those who are harmed by pests and diseases, remove the diseased plants, prevent the spread, and use 90% of the trichlorfon 800 times liquid to control the roots.

2 Garlic is prone to leaf blight, blight, gray mold, etc. in spring; it is necessary to spray pesticides such as chlorothalonil, keering, metalaxyl and kelu in time for prevention and treatment.

3 Spray with 40% dimethoate 1000 times to control root lice. Use sweet and sour liquid to trap winter flies and onion flies. Do not use pesticides during the garlic picking period and 15 days before the garlic harvest. Please take precautions according to the situation.
