Burdock is a vegetable that provides food from its fat, fleshy root, and the petiole and young leaves are also edible. In addition to vegetables, burdock fruits and roots can be used as medicine. At the same time, burdock seed oil content of up to 18.2%, can be used as industrial oil. .V8Lauz8 \x0d\ I. Cultivation season. Burdock cultivation in the open ground, spring and autumn can be sown, mainly spring sowing, fall cultivation can be sown in early August to early September, warm areas can be harvested in December. O k=hT|}Y \x0d\ Second, selecting, preparing and applying basal fertilizer. Planting burdock should choose the terrain sunny, convenient drainage and irrigation, deep soil, fertile loam or clay loam plot. Burdock taboo crop, should be implemented 3-5 years of crop rotation, the previous crop to cereal crops or leafy vegetables more suitable. Plots of land selected, plowing depth of 40-50 cm, per mu of fully rotted stable manure or compost 2500-3000 kg, mixed with 30 kg of calcium superphosphate and 20 kg of potassium chloride, turned into the soil, rake flat. Make raised beds 2-3 meters wide (with furrows), or high ridges 65-70 cm wide and 15 cm high. (V2fRv \x0d\ III. Sowing. Rinse the seeds with water, put them into 1000 times methoxyethyl chloride mercury solution for 1 hour, fish them out and put them in water for another 24 hours, take them out and sow them. z9Rp`z&`E \x0d\ Burdock can be sown in the field by direct seeding, strip sowing or spot sowing. Strip sowing according to 30 cm row spacing to open a shallow furrow (furrow depth of 3 cm), the amount of seed per mu about 500 grams; spot sowing of rows and plants spacing of 30 cm × 20-25 cm, each hole under the seed 4-5. After sowing mulch 2 cm, if the soil is too wet, mulch can be thinner. sowing in early to mid-March sowing needs 10-15 days after seeding; sowing in early April, sowing about 7 days after the seedling. @_}P-h \x0d\ Fourth, field management. Seedlings grow 2-3 true leaves time seedlings, strip sown seedlings about 8 cm apart, spot sown each hole can stay 2 seedlings. Seedlings have 5 pieces of true leaves to unfold, to set seedlings in time, strip sowing the distance between the seedlings to stay 20-25 cm. From seedling to sealing rows, should be plowed 2-3 times, in addition to eliminating weeds in the early plowing, but also can loosen the soil, temperature; sealing rows before the last plowing should be combined with the roots to cultivate the soil. On the weed heavy plots, after sowing to the seedling, per mu with casein emulsion 80-100 ml, to 10 kg of water mixing evenly and then spray the ground. Burdock needs more fertilizer, in the application of sufficient base fertilizer, on the basis of the reproductive period, usually to chase 3 times of fertilizer. The first time after the seedling, 10-15 kg of urea per mu. The second time in the plant peak long period, spring sowing in about early May to late June, autumn sowing in warm areas in about late September, with urea 10 kg per mu. The third fertilizer in the fleshy roots began to expand period, spring sowing about in early to mid-July, autumn sowing in the pre-frozen, 15 kg of urea per mu. Autumn sowing burdock at the time of freezing to irrigate a freezing water, roughly during the period of light to heavy snow, the specific irrigation time should be in the night freezing day time for the best, the surface should not be frozen. 8VXH+5's \x0d\ V. Harvesting. 100-130 days after sowing is the right time for harvesting. Usually sown in early March, mid-June can begin to harvest, mu yield of about 1,000 kilograms; September-November harvest, mu yield of 1,500-2,000 kilograms, warmer areas until the following spring can be harvested at any time in early April, spring harvest mu yield of up to 3,500 kilograms. Autumn sowing, from early December to early April of the following year can be harvested at any time. But harvesting too late is easy to hollow
