Fresh burdock is rich in crude fiber, protein, calcium, iron, carotene and vitamins. Therefore, the burdock is popular among the public. Let’s take a look at the burdock. Planting time and method. First, what environment is suitable for growing calves? Burdock prefers light, warm and humid climate conditions, and is relatively heat-resistant and cold-resistant. The suitable growth temperature is about 20 ° C to 25 ° C. It needs to be planted in fertile soil with deep soil and good drainage. It is ideal for alluvial soil or organic rich night tide soil. Second, when is it suitable for sowing, seedling, and topdressing? Burdock can be sown in spring and autumn, and spring sowing is often carried out from mid-March to mid-April. Autumn sowing is often carried out in early August. Before sowing, pits are 30 to 40 cm wide and 90 cm deep at a distance of 60 cm. Apply 1500 kg of decomposed farmyard manure as a base fertilizer per mu, and apply a layer of farmyard manure and a layer of soil to the pit. Soak seeds for germination before sowing, soak seeds in warm water at 25 ° C to 30 ° C for about 4 to 6 hours, germination at 25 ° C to 30 ° C, and soak seeds when the seeds are white for about 30 hours. According to the plant spacing of 25 to 30 cm, about 4 seeds per hole, covering 2 cm of soil and slightly suppressing, so that the seeds are in close contact with the soil. The dosage of each acre is about 400 grams, about 10 to 20 days after sowing, and the seedlings are once after emergence. When there are 2 to 3 true leaves, the seedlings are once again. When there are 3 to 4 leaves, the seedlings are 25 cm. about. After the seedlings are planted, they will enter the vigorous growth period for the first fertilization. The per mu of manure will be about 1000 kg or about 10 kg of nitrogen fertilizer and about 15 kg of potassium fertilizer. The second top dressing was carried out in mid-June, with about 10 kg of nitrogen fertilizer per acre and about 15 kg of potash. The soil is fertilized while fertilizing. The burdock is afraid of cockroaches, pay attention to drainage after the rain. 3. When can I harvest? The burdock grows from planting to harvesting for a long time. Spring sowing starts in early June and can be harvested in early April. Some areas are planted in April and harvested in October. The yield per mu is about 2,000 to 3,000 kg. Autumn sowing is often planted in late August, and the harvest period is from early December to early April. At the time of harvest, the petiole of 10~20 cm is often left on the plant, and the leaf stalk is cut off. The shovel is dug 80~90 cm deep on the side of the sirloin root of the burdock to reveal the burdock root. You can hold the base of the burdock and tilt it upwards. Out.
