After many years of experimentation and demonstration, Sheyang County has made a series of efficient cultivation models for lettuce, cowpea, and garlic. Shed lettuce is planted in the middle and late September, transplanted in late October, and harvested in late March in the second year; cowpeas are raised in small arch sheds in mid-March, transplanted into greenhouses at the end of April, harvested at the beginning of July, and harvested. After Qingtian, garlic seeds were broadcast in the middle and late July, and garlic was launched in mid-October. According to statistics, greenhouse lettuce generally yields 5,000 kilograms per mu with an efficiency of 3000-4000 yuan; cowpea yields 1500-1800 kilograms per mu, and the benefit is about 2,000 yuan; and the yield of green garlic is 2000 kg, and the benefit is 3000-3500 yuan. In 2008, the county had planted an area of ​​5,000 mu in this model, and the planting area continued to increase in the past two years. This pattern is mainly used for planting lettuce in greenhouses. In the first half of 2010, due to the higher price of lettuce, the benefit of this single mu will be over 5,000 yuan.

Variety Selection Lettuce is selected from cold-tolerant, high-yield, and marketable disease-resistant varieties, such as cold-resistant, white-skinned, cold-resistant, green, purple-leaf and fragrant, etc.; cowpeas are selected for use in sprawling, high-quality, high-temperature, and high-resistance varieties. Yangxun 40 and other varieties; green garlic selection of high-quality, high-yield, disease-resistant, resistant to storage and transportation varieties, such as March yellow, dihydrate and so on.

Planting specifications 4.2 meters wide shed built 2 畦, 畦 width 2 meters, the middle sulcus width 20 cm, shed width 40 cm. Lettuce colonization spacing 30-35 cm, spacing 20-25 cm, planting 7000-9000 per acre; cowpea row spacing 60 cm, hole spacing 30 cm, 2-3 per hole; garlic digging every 2 meters before sowing Ditch, dug a horizontal trench every 20 meters, planting row spacing are 7 cm, plant 120,000 per acre, for the morning city of garlic, can plant 180,000 -200,000 per acre.

Field Management (1) Lettuce. Choose fertile, well-drained plots to make seedbeds, sow seedlings in the open field in mid-to-late September, make shallow crops after sowing, and preserve seedlings. Timely seedlings (or false seedlings) are transplanted when they have 4 to 5 true leaves. In late October, plough and fertilize, open trenches, build rafts, level the ditch, and transplant with soil. Before transplanting, sufficient base fertilizer should be applied, and 2500 kilograms of manure and urine per acre, 100 kilograms of cake fertilizer, 50 kilograms of superphosphate, and 50 kilograms of 25% ternary compound fertilizer. After pouring water, cover the film. When the stem begins to grow, dilute the water frequently, but avoid using excessive human urine to prevent the meat stem from cracking and rotting. (2) Kidney beans. The use of semi-high sorghum planting, before planting combined with high-quality organic fertilizer per acre 300 kg, 3 kg of pure nitrogen, phosphorus pentoxide 6 kg, potassium oxide 4 kg. Timely framed vines, while swaying buds. (3) green garlic. Choose a garlic clove with a uniform size and a hundred petals over 300 grams. In late June, soaked in water, soaked in 5-8 °C environment, 10-20 days garlic seed germination when sowing. It is required that the cultivation and irrigation of fields be convenient and cannot be repeated. Before ploughing per acre Shi cooked cake fat 100-200 kg, 42% garlic fertilizer 40 kg or ammonium bicarbonate 50-60 kg, 50-70 kg of superphosphate, 15-20 kg of potassium sulfate. After fertilizing, plunge 20-30 cm deep so that the soil is well-mixed and the soil surface is loose. Place 2 pieces of wood that is 1 meter long and 20 centimeters wide on the surface of the virtual soil. People should move on the wooden board to move back and sow. The feet should not be treaded directly on the surface. The depth of the planting should not be exposed on the surface of the garlic. In order to increase the length of pseudo-stemmed garlic and fertilize soil, evenly spread 3-4 cm thick corn stalks or wheat straw after sowing, covering 2000-3000 kg per mu. During the period of growth, garlic was sprayed in a timely manner in case of drought, and spraying with small water was appropriate. Garlic 2-3 leaf stage, if the growth is weak, can use more than 200 million effective bacteria per acre / g, mixed bacteria rate is less than 15%, organic matter is greater than 20%, pH 6-7.5 1 kg of biological fertilizer added water 35-45 kg soaked for 24 hours, take the supernatant spray, 7-10 days once, even spray 2-3 times.

During pest growth, lettuce must be properly ventilated and dampened. During the later period, attention should be paid to the control of pests and diseases. The ventilation openings of the greenhouses should be sealed with nylon net yarns to prevent insects and other pests from flying into the enclosure. Diseases are downy mildew, gray mold, sclerotia, soft rot, etc.; pests are mainly aphids, pay attention to timely prevention and treatment. The cowpea pests are mainly small ground tigers and soybean pods, and they should pay attention to timely prevention and treatment. Garlic has fewer pests and diseases and generally does not require chemical control.
