Planting technique of Sophora flavescens planting time and method of Sophora flavescens

Sophora flavescens has been planted in China for a long time, and there have been some records about it since ancient times. Sophora flavescens is currently selling well in the market of our country. Which leads to the idea that a lot of people want to grow it. Before planting, you must have an in-depth understanding of it.

Planting technique of Sophora flavescens

1. Soil selection and preparation: Sophora flavescens is a deep-rooted plant. It is better to choose sandy loam and clayey loam with deep soil layer, fertile soil and good drainage. Apply compound fertilizer, ploughing 20ml 25cm, fine and leveling, and open the border 1.5 meters wide.

2. Seed propagation: seed treatment should be carried out before sowing. Methods: the seeds were soaked in 40-50 ℃ warm water for 10-12 hours, then drained slightly before sowing, or sown by wet sand stratification (seeds and wet sand mixed with 1 ∶-3) for 20-30 days.

3. Root propagation: it can be carried out in both spring and autumn. It is planted after falling leaves in autumn and before sprouting in spring. Spring and autumn cultivation were combined with the harvest of Sophora flavescens. Dig out the mother plant, cut off the thick roots for medicinal use, and then cut into several plants with a knife according to the number of buds and roots on the mother plant, each plant must have 2 or 3 roots and buds. The seedlings were planted according to the above-mentioned plants and row spacing, and 1 plant was planted in each hole. Cover the soil and water thoroughly after planting.

4. Strip broadcast or hole broadcast. From the point of view of field management, hole sowing is better. Some seedlings are used for transplanting, but transplanting is more tedious. First repeatedly rake the bed, according to the row spacing of 40-50 cm, plant spacing of 30 cm to dig holes, hole depth of about 3 cm, each hole sowing 6-8 grains, covering flat, slightly suppressed. The sowing rate is 2 kg per mu. The row spacing of strip sowing is 30 cm, the plant spacing is 20 cm, and the seed is 4 kg per mu.

Planting time and method of Sophora flavescens

1. Sowing time. Spring sowing or autumn sowing is fine. It is necessary to cover after autumn sowing, otherwise the soil surface is easy to harden, which is not conducive to spring emergence. Autumn sowing should be early and not late. Seeds can be sowed after maturity and finished before soil thawing at the latest. Spring sowing should be planted before and after the Qingming Festival, when the soil moisture is better, which is conducive to seedling emergence.

2. Sophora flavescens can be propagated by seeds or by individual plants. The sowing time is divided into spring sowing and autumn sowing. Spring sowing before and after the Qingming Festival, autumn sowing before freezing. Seed propagation: soak the seeds of Sophora flavescens in water for about 50 ℃ for 12 hours before sowing. Then sow on the whole border surface according to the row spacing of 65 × 50 cm, watering to preserve soil moisture to facilitate seedling emergence. The sowing rate is 2 kg per mu. 5 seeds were put in each hole. Split propagation: the Reed head of Sophora flavescens was cut into several pieces according to the number of bud eyes, and each piece had 3 bud eyes, which were used as breeding materials. After the wound healed, it was planted on the finished border surface according to the row spacing of 65 × 50 cm. Watering to preserve soil moisture, in order to survive.

3. After Sophora flavescens seedlings, herbicides in the field should be used to treat the soil before the seedlings, which can effectively control all kinds of weeds. Water in time in dry weather, pay attention to drainage in cloudy and rainy weather. After budding, in addition to leaving seeds for planting, buds should be removed to prevent nutrient consumption. The Beginning of Autumn is topdressing once a year: 10 kg of urea and 10 kg of potassium dihydrogen phosphate per mu. Sprinkle a layer of soil fertilizer on the border in winter.

Field management of Sophora flavescens

1. Rational drainage and irrigation. Irrigation should be made in time after drought and fertilization to keep the soil moist. Attention should be paid to drainage in the rainy season to prevent stagnant water from rotting roots.

2. Ploughing and weeding. Weeding and soil cultivation should be carried out at the seedling stage to keep the field free of weeds and the soil loose and moist, so as to facilitate the growth of Sophora flavescens.

3. Topdressing. On the basis of applying sufficient base fertilizer, topdressing was carried out twice a year: the first time was in the middle and last ten days of May, 2000kg was applied per mu of dilute manure water, and the second time was carried out in the first and middle of August, mainly with phosphorus and potassium fertilizer. The number of fertilizers should be increased appropriately in barren plots.

4. Pick flowers. In addition to keeping the seed land, the flower bolts should be cut off in time so as not to consume nutrients.

Harvest and processing of Sophora flavescens

1. Harvest. The roots were harvested after the stems and leaves withered in autumn 2-3 years after sowing. Because the roots are deep, you should dig deeply and be careful not to break them. It can also be harvested with a deep plough.

2. Processing. Dry the recovered Sophora flavescens root according to the length of the stick, and remove the Reed head and tail root. Dry or dry.

The planting method of Sophora flavescens is relatively simple, mainly to do a good job of site selection. In terms of time, there are generally two seasons of spring and autumn for sowing. After sowing, we also need to strengthen the field management of Sophora flavescens, reasonable fertilizer and water, timely weeding can not be neglected. Only after doing these well can we ensure the growth of Sophora flavescens.
