The conditions of the soil were selected as flat terrain, convenient drainage and irrigation, deep soil plowing, fertile soil, suitable soil structure, and good physical and chemical properties. Sandy soil is appropriate. Seedlings use seeds full, no impurities, no wormholes, cold resistance to pests and diseases, heat resistance, strong tiller, appearance and intrinsic quality. The amount of mu for seedlings is 5-6 kg, and 6-7 mu can be transplanted in Daejeon. Seed treatment. Available dry seed live (Spring sowing mainly), Guangzhou in October-December sowing, transplanting in March-April, can also be soaked in warm water at 40 °C for 12 hours to remove pod seeds and impurities, wash the mucus on the seed Germination. Soak the seeds with a damp cloth and put them under the condition of 16-20°C to germinate. Rinse 1-2 times with fresh water every day. More than 60% of seeds can be sown when exposed white. Soil fertigation. Seedbeds should be selected from drought-pourable and high-dry plots. The sandy loam should be used. Deep plowing should be performed before sowing. Shallow ploughing, fine plowing, and combination with fertilization, leveling and hoeing should be performed before sowing. 12-14 cm, width 100-120 cm. Sow the ditch, step on it, step on the ditch, and then ditch the water. After the water infiltrates, mix the germinated seeds with 2-3 times the sand in the gully. Cover the film or straw and remove the bed cover when 70% of the seedlings emerge. Water and fertilizer management after sowing. Before emergence, it takes 2-3 days to water once to keep the soil surface moist. From the seedlings to the seedling height of 16 cm, water is poured once every 7 days or so. Combined with watering, 3 kg of nitrogen fertilizer is collected for each epidemic, and the wet season is drained to prevent flooding. After the beginning of autumn, combine topdressing with watering twice, each applying 4 kg of nitrogen fertilizer, and generally do not harvest before planting, in order to promote the growth of strong seedlings. When the weather turns cold, watering should stop. In addition, timely weeding. Planting seedlings for 120 days, seedlings grow 7-9 leaves, plant height to 18-20 cm when the colonization period. When planting, it is necessary to stagger the high temperature and high humidity season. The main planting methods include dense planting, dense planting, planting of small ridges, and wide ridge planting. Take the leek seedlings out, cut the roots of the fibrous roots, leave 2-3 cm to promote the development of new roots, and then cut off the leaves to reduce the evaporation of leaves and maintain the balance of root absorption and leaf surface evaporation. Plant spacing 1020CM, 8-10 per hole planting; or 30-3620CM, planting 20-30 plants per hole, planting depth to not bury the tiller section is appropriate. After three days of water and fertilizer management, the plant was used to pour water twice. The seedlings were planted in 2 to 3 times in a timely manner. The soil was in a semi-wet and dry state. The rainy season should be drained in time. Leek has a strong resistance to fertility, planting before the deep-spotting site preparation (2 meters Bao Hang) full application of base fertilizer, Mushi 2000 kilograms, the principle of fertilization is the use of organic fertilizer and inorganic fertilizer, the ratio is not less than 1:1. Fertilization should be based on the growing trend, weather, soil moisture conditions, to take the principle of light and diligent planting, seedling height below 35 cm, Mushi 2% compound fertilizer water 500 kg; seedling height above 35 cm, Mushi 3% decomposed manure 800 kg, At the same time adding 5 kg of compound fertilizer, the weather should increase the dilution of drought. After 45 days of planting, a small amount of flowers can be collected. In that year, the emphasis was on "cultivating strong roots and cultivating roots." Harvesting is suitable in the early morning. In the early stages of planting, mixed pods or other leafy vegetables can cool down and increase income. In the second year of cultivation, the new species of leeks are not harvested. In the second year, they are harvested with indigo and pods. The annual pods can be harvested. Each harvest is conducted with cultivating loose soil, fertilizing and earthing. . If the plan is to soften the yellow crop, the harvest will be extended for 7 days to harvest. There are many methods for culturing glutinous rice, and tile-softening methods are often used locally. This method is to use a special high 30-40CM, diameter 15-20CM circular tile, is now more used cement products, use it to cover in the leek on the shading, the upper end of the mouth, covered with a cap during the day, Ventilate and cool at night. Before softening, it should be cultivated and weeded, topdressed with a heavy fertilizer, cultivated with mud and pest control. Softening time, 7-8 days in summer; 10-12 days in winter. The third year is mostly green and yellow. The technology of cultivating glutinosa yellow is the root of leeks growing on the basis of their own storage of nutrients. Under the condition of no photosynthesis, the leeks and leeks that have excellent taste, light yellow color, little cellulose, and soft texture are formed. Yellow, the market demand is strong, and the planting efficiency is very good. The specific cultivation methods are as follows: First, choose the land for the earthworms, and choose the loam or sandy loam soil with deep soil, loose fertility, good ventilation, water and fertilizer conservation, drainage and irrigation. To be fat enough (such as nitrogen, phosphorus, potassium, and other necessary elements to be adequate and reasonable match), satiated, deep tumbling, leveling do as required, so that the ditch is connected, drainage and patency. Second, the selection of fine broadcast. Before the next species, we must first select a good seed and apply a 800-fold solution of the new high-fat membrane for seed dressing treatment (repellent underground pests, isolate virus infection, do not affect the germination function, strengthen respiratory intensity, and increase seed germination rate). Can be timely sowing (Spring sowing or autumn sowing), to plan a good spacing, precision under the broadcast. After the next kind of planting, thin sand fine soil shall be sprayed on the surface of the new 800-times high-fat film to spray the soil surface, which can protect the water from evaporation, sun protection and drought resistance, heat preservation and antifreeze, anti-soil compaction, suffocation and isolation of pests and diseases, and increase the emergence rate. . Third, seedling management. Seedling stage should pay attention to the reasonable supply of water and fertilizer, keep the soil moist, and spray a new high-fat membrane to protect the soil to protect the fertilizer, to prevent the bacteria infection, and increase the intensity of photosynthesis. Attention should be paid to timely cultivating and weeding and transplanting seedlings, and spraying with strong stalks in time to promote rapid growth of seedlings, thick stems and generous leaves, which are conducive to the accumulation of photosynthetic products. Radon is harmful to leek, and it is necessary to timely kill the enemy with 4000 times of liquid (or kill 300 times of dichlorvos at a fast rate) + 800 times of new high fat film. Fourth, cut green and cover grass curtains. Soil cultivation is the main measure to soften the stalks. The soil is generally divided into 2 times, according to the growth conditions and temperature in time. Each time about 10 days or so of earth, after the earth is cut, the upper barley must be cut off and puddles must be taken. It is necessary to slightly apply compound fertilizer + spray 800 times the new high-fat film to ensure the effectiveness of heat preservation and fertilizer. Cover grass curtains in a timely manner to make them less sunbeams. Spray water at a proper time to maintain a certain humidity. According to the growth situation, spray another strong stalk and promote vigorous growth. When Huang Long grows to meet the requirements of the commodity, it must harvest it in time. After harvesting for 1 to 2 days, fertilize and transfer to the next round of yellow cultivation. Within one year, it can harvest 2-3 times. Leek cultivation (1) Strengthen the management of fertilizer and water: The cultivation of Chinese leek flowers enters the lucrative period of Mayflower from May to May in the second year. In order to meet the needs of continuous harvesting of flower stems for nutrient, we should apply imported potassium sulfate compound fertilizer every week. 30 pounds, in addition, in March and June respectively apply a decomposed organic fertilizer, 15 tons per acre; in the off-season harvest can be fertilized once every half months, each time per mu application of potassium sulfate compound fertilizer 30 pounds; to meet the leek To spend on phosphorus and calcium, apply phosphate fertilizer once per quarter, 70 pounds per acre, and apply lime 1-2 times per year, 80-100 pounds per acre. Spray water after each application of fertilizer to prevent fertilizer damage. Leek flower afraid of jealous water, after the rain to drain in time, usually meet with dry water to be poured or irrigation "running horse water", keep moist but not water. Adequate moisture, nitrogen or potassium, calcium are easy to cause stems through heart. (2) Pay attention to soil cultivation: Since the leek has the characteristic of rooting, cultivation work cannot be ignored. Pre-winter (after winter flower bud differentiation) should be combined with application of winter fertilizer (Mushi import compound fertilizer 30 kg) for a large earth to promote growth, so that plants can accumulate more nutrients required for normal bolting in the coming year, usually can have Plan to make 1-2 times of small earth. The soil should be cultivated on a sunny day, and the top soil that has been weathered on the ground should not be used to cultivate the roots of the plants. When the soil is cultivated, the outward opening leaves must be put together and cultivated. This measure not only prevents lodging, but also improves the ventilation and light transmission in the field. (3) Intertillage and weed control, timely sparse seedlings: during the growth of leeks, mild climate and rain, weeds prone to occur, we must cultivator weeding, loosen the topsoil, increase soil temperature, in order to facilitate rooting hair tree. Yellow leaves and dead leaves are often removed and concentrated in the field to reduce the occurrence of pests and diseases, which is conducive to ventilation and light transmission. However, it is not appropriate to use a knife to cut the seedlings, otherwise it will affect the growth of the plant and the accumulation of nutrients in the future, and it will have a certain influence on the yield of flowering moss. After the plants are sealed, if excessive trees are found and the normal growth of the plants is affected, the thinning plants should be promptly carried out so as not to hinder normal production. The sparse plantlets are usually harvested during off-season harvesting (generally from the first and second year after planting). Do not use sparse seedlings in the first half of the year. (4) Collecting flower stems in time: The buds of the general stems are just 6-8 days after they protrude from the pseudo stems. The stem length and the length of the leaves are approximately the same. The buds' fullness shape must be harvested when they are slightly round in winter and sharp in summer. The most important thing is to grasp the degree of fibrosis at the base of the stem, and the broken stems are easily harvested after gently bending.
