NOVELTY - Cultivating winter green manure tea involves (a) plowing soil deeply, flattening soil, sowing green manure tea seeds, applying phosphate fertilizer, sowing and covering with soil, (b) cutting seedlings, (c) soaking the seeds in water, filtering and planting seeds, (d) spraying water and Rhizobium nutrient solution to germinated seed, and sowing, (e) cutting seedling, (f) spreading seeds and applying calcium superphosphate and urea, and promoting the growth and (g) harvesting winter green manure.    USE - The method is useful for cultivating winter green manure tea including hairy vetch seed, light vetch seed, common vetch seed and cow vetch seed (claimed).    ADVANTAGE - The cultivation method is simple and reduces labor-cost and labor-intensive.    DETAILED DESCRIPTION - Cultivating winter green manure tea involves (a) plowing soil deeply, flattening the soil, sowing 0.75-1 kg/acre green manure tea seed at a distance of 40-50 cm during fourth and fifth month, using strip casting method, shallow trenching the soil 8-10 cm deep, applying phosphate fertilizer, covering 2 cm with thick soil, sowing in soil, and finally covering the sown seed with thin layer of soil, (b) cutting 25 cm seedling for the first time after 7 months, (c) soaking the green manure seeds in water containing 400 times carbendazim and 800 times methyl thiophanate at 25-30 degrees C for 12-14 hours, removing and filtering the seeds using gauze and planting seeds, (d) spraying water to seeds using mist sprayer until shell breaking and germinating at a rate of 90%, and spraying Rhizobium nutrient solution to germinated seed and processing for 1-3 hours, and sowing germinated tea seed 2-2.5 kg/acre directly in green manure during summer using scattering method, (e) cutting 40-50 cm seedling from summer sown green manure plants for the second time, after 3-5 days, (f) homogeneously spreading the obtained tea seeds to soil, and applying 8-10 kg/666.7 m2 calcium superphosphate and 4-5 kg/666.7 m2 urea, and promoting the growth of winter green manure, and (g) harvesting winter green manure using manual or mechanical method, during third and forth month of next year.
