<p>Sophora flavescens has been cultivated in our country for a very long time, and records about it date back to ancient times. Sophora flavescens currently sells well on the market in our country. This has inspired many people to want to grow it. Before planting, one must have an in-depth understanding of it.</p><p></p><p><strong>Cultivation Techniques for Sophora flavescens</strong></p><p>1. Site selection and land preparation: Sophora flavescens is a deep-rooted plant. It is best to choose sandy loam and clay loam with deep, fertile soil and good drainage. Apply compound fertilizer, plow and turn the soil 20—25 cm deep, break up clods and level the soil, and make beds 1.5 m wide.</p><p>2. Seed propagation: Seed treatment must be carried out before sowing. Method: soak the seeds in warm water at 40-50 degrees C for 10-12 hours, then remove them, drain them slightly, and sow; alternatively, stratify them with wet sand (mix seeds and wet sand at 1:3) for 20-30 days before sowing.</p><p></p><p>3. Root division propagation: This can be done in both spring and autumn. Autumn planting is carried out after leaf fall, and spring planting before bud break. Both spring and autumn planting are done in combination with the harvest of Sophora flavescens. Dig out the mother plant, cut off the thick roots for medicinal use, then, according to the number of buds and roots on the mother plant, cut it into several plants with a knife; each plant must have 2-3 roots and buds.

From the perspective of field management, hole sowing is better. Some also use seedling raising and transplanting, but transplanting is rather troublesome. First rake the bed surface repeatedly, then dig holes at a row spacing of 40-50 cm and a plant spacing of 30 cm, with holes about 3 cm deep, sow 6-8 seeds per hole, cover level, and press lightly.

Then sow them in holes at a row and plant spacing of 65×50 cm on the prepared bed surface, water to preserve soil moisture, and promote emergence. The sowing rate is 2 kg per mu. Place 3—5 seeds per hole. Division propagation: cut the rhizome of Sophora flavescens into several pieces according to the number of buds; each piece has 2—3 buds and is used as propagation material.

Sophora flavescens has been cultivated in China for a very long time, and records about it date back to ancient times. Its sales on the Chinese market are currently quite good. This has prompted many people to want to grow it. Before planting, you must have an in-depth understanding of it.
Sophora flavescens cultivation techniques
1. Site selection and land preparation: Sophora flavescens is a deep-rooted plant. Choose sandy loam and clay loam with deep, fertile soil and good drainage. Apply compound fertilizer, plow 20—25 cm deep, break up the soil finely and level it, and make beds 1.5 m wide.
2. Seed propagation: Seeds must be treated before sowing. Method: soak the seeds in warm water at 40-50°C for 10-12 hours, then remove them and drain them slightly before sowing; you can also stratify them with wet sand (mix seeds and wet sand at 1:3) for 20-30 days before sowing.
3. Root division propagation: This can be done in both spring and autumn. Autumn planting is done after leaf fall, and spring planting is done before budding. Both spring and autumn cultivation are carried out in combination with the harvest of Sophora flavescens. Dig out the mother plant, cut off the thick roots for medicinal use, then, according to the number of buds and roots on the mother plant, cut it into several plants with a knife; each plant must have 2-3 roots and buds. Plant the seedlings at the above spacing, with 1 plant per hole. After planting, cover with soil and water thoroughly.
4. Drilling or hole sowing. From the perspective of field management, hole sowing is better. Some also use seedling transplanting, but transplanting is rather troublesome. First rake the bed surface repeatedly, dig holes at a row spacing of 40-50 cm and a plant spacing of 30 cm, with holes about 3 cm deep, sow 6-8 seeds per hole, cover flat, and press lightly. The sowing rate is 2 kg per mu. For drilling, the row spacing is 30 cm and the plant spacing is 20 cm, using 4 kg of seed per mu.
Sophora flavescens planting time and methods
1. Sowing time. Either spring sowing or autumn sowing is fine. After autumn sowing, it needs to be covered; otherwise the soil surface tends to crust, which is not good for emergence in spring. Autumn sowing should be early rather than late; sow as soon as the seeds mature, and finish sowing before the soil freezes at the latest. Spring sowing should be done around Qingming, when the soil moisture is relatively good, which helps emergence.
2. Sophora flavescens is propagated by seed, and can also be propagated by division. The sowing period is divided into spring sowing and autumn sowing. Spring sowing is around Qingming, and autumn sowing is before the ground freezes. Seed propagation: before sowing, first soak the Sophora flavescens seeds in water at about 50°C for 10—12 hours. Then sow them in spots on the prepared bed surface at a row and plant spacing of 65×50 cm, water to preserve moisture, so as to help emergence. The sowing rate is 2 kg per mu. Place 3—5 seeds per hole. Division propagation: cut the Sophora flavescens root crown into several pieces according to the number of bud eyes; each piece has 2—3 bud eyes and is used as propagation material. After the wounds heal, plant them on the prepared bed surface at a row and plant spacing of 65×50 cm. Water to preserve moisture, so as to help survival.
3. After Sophora flavescens seedlings emerge fully, for large-scale planting, a medicinal field herbicide should be used for soil treatment before emergence, which can effectively prevent and control various weeds. Water promptly in dry weather, and pay attention to drainage in rainy weather. After budding, except for plants kept for seed, the flower buds should be removed to prevent nutrient consumption. Apply fertilizer once around the Beginning of Autumn each year: apply 10 kg of urea and 10 kg of potassium dihydrogen phosphate per mu. In winter, spread a layer of farmyard manure on the bed surface.
Field management of Sophora flavescens
1. Reasonable irrigation and drainage. Irrigate promptly during drought and after fertilization to keep the soil moist. In the rainy season, pay attention to drainage to prevent waterlogging and root rot.
2. Cultivation and weeding. During the seedling stage, carry out cultivation, weeding, and earthing up to keep the field free of weeds and the soil loose and moist, so as to help Sophora flavescens grow.
3. Topdressing. On the basis of applying sufficient base fertilizer, topdress 2 times each year: the 1st time in mid-to-late May, applying 2000 kg of diluted manure water per mu; the 2nd time in early-to-mid August, mainly with phosphorus and potassium fertilizers. Poor plots should appropriately increase the number of fertilizer applications.
4. Flower removal. Except for seed plots, promptly cut off the flower stalks to avoid consuming nutrients.
Harvesting and processing of Sophora flavescens
1. Harvesting. Dig the roots in autumn 2-3 years after sowing, after the stems and leaves wither. Because the roots go deep, dig deeply and be careful not to break them. You can also use a deep plow to turn them up for harvest.
2. Processing. Dry the harvested Sophora flavescens roots in the sun separately according to the length of the root strips, and remove the root crown and tail roots. Dry them in the sun or by artificial drying and they are ready.
The cultivation method of Sophora flavescens is relatively simple, and the main thing is to do a good job in site selection. In terms of timing, it can generally be sown in spring and autumn. After sowing, field management of Sophora flavescens also needs to be strengthened; reasonable fertilizer and water management and timely weeding cannot be neglected. Only after doing these well can the growth of Sophora flavescens be ensured.
