Scrophularia breeding method and cultivation management points
Scrophulariaceae is a kind of traditional Chinese medicine plant with good medicinal properties. It has wide adaptability, warm and humid climate, and has certain cold and drought tolerance. The soil is characterized by deep, fertile, loose, well-drained loam. Not suitable for continuous operation. The following brings you a cultivation technique of Scrophularia. First, the breeding method Seed propagation, cutting propagation and sprout propagation can be used. Production uses multi-germ buds (root buds) to breed. 1. Seed propagation: The mature seeds harvested in the autumn are stored in a dry place indoors and planted in the spring of next year. The southern region can be broadcast in the autumn. Wet the ground with water, soak it evenly, cover the soil, and cover with straw to keep warm. After the emergence of the seedlings, the manure water is poured and the seedlings are removed. 2. Cutting propagation: In July, the cuttings of Scrophularia sinensis were used for cutting. Cut the Scrophularia sinensis with a short section of about 15 cm and insert it into the seedbed to strengthen the management of water and fertilizer. After the survival, transplanted in the spring of the next year. 3. Propagation of the buds: Propagation of the buds is carried out by rhizomes with spores. In the north, the breeding materials selected during the autumn harvest are stored in the sputum, and the 窖1 square meter square is about 1 meter deep. The bud is placed in the middle of the raft and is about 30 cm thick. It is covered with a layer of sand. As the temperature is lowered, the sand is gradually added, and the thickness of the sand is about 30 cm. When the temperature in the spring rises, the sand is gradually removed, and the transplanting is taken out in early April. In the southern region, planting is carried out in autumn. When planting, the rhizome is divided into several pieces, each of which has 2 to 3 buds, and one rhizome is planted at each hole, and the buds face upward. In addition, some also use ramets to breed. Second, the choice of land Scrophulariaceae is a deep-rooted plant that should be planted in deep, light loam or medium loam. Avoid continuous cropping. The former is best for legume or grass crops. After the previous harvest, each 667 square meters of cooked manure 1000 kg, deep and fine flattened, according to 1.3 to 1.5 meters to do the ditch. Third, planting On the crotch surface, the hole is 40 cm apart and the hole is 30 cm. The hole depth is 10 cm. Plant the buds in the hole, one hole per hole, and the buds face up. Each hole cover 1 plant ash mixed with human and animal manure, cover the soil to the level. Seed seedling transplanting and cutting seedling transplanting, the density is the same as that of the bud planting. Fourth, field management 1. In the process of cultivating and weeding, Scrophularia sinensis is generally cultivated and weeded 3 times. At the end of March and the beginning of April, when the seedlings grow to 5 cm or so, timely weeding and weeding will promote the growth of seedlings; in mid-May, proper weeding and weeding should be carried out; from June to July, weeding and weeding should be carried out again before the Miaofeng line, and the soil is cultivated. Promotes root growth and prevents lodging. 2. Topdressing after topdressing. After the secondary cultivating, about 1500 kilograms of manure and manure per 667 square meters can be applied, a small amount of nitrogen fertilizer can be applied, 10 kilograms of urea per 667 square meters; after the second cultivating, the manure and manure with a larger concentration are applied, every 667 The dosage of square meter is 2000 kg, 30 kg of superphosphate is added, and 15 kg of potassium sulfate; when the third is cultivating, the compost of phosphorus and potassium fertilizer is applied, 1500 kg of compost is used for 667 square meters, 50 kg of superphosphate, sulfuric acid Potassium 25 kg. After the top dressing, the soil is cultivated. 3. When the local part of the flowering flower is flowering, cut the flower buds in time to avoid competing for nutrients to promote the expansion of the roots. 4. Water management Drainage is often cleared during the rainy season. In addition to severe drought, watering is generally not required. Even if you water it, you can't overdo it. V. Harvest processing 1. Harvest: Scrophulariaceae was planted in the same year, and the local upper part was withered during October-November. Cut the stalk first, then plan the underground part and select the rhizome with the bud. 2. Processing: The roots that can be used for medicinal purposes are dried during the day and piled up at night. Repeatedly stacking and drying to a semi-dry, accumulating for 2 to 3 days of "sweating", making the inside of the roots black, and then drying in the daytime, accumulating at night, until all dry. It can be baked in the rainy days, the temperature is about 60 °C, and it is turned at the right time. When it is dried to half dry, it is "sweating" and then dried.
