High-yield planting techniques of Scutellaria barbata

First, soil selection: Scutellaria barbata likes warm climate and humid, half-yin and half-yang environment, it is appropriate to choose loose, fertile, well-drained soil to plant, avoid stagnant water.

Second, seedling cultivation: seed propagation is the main method, and it can also be propagated separately.

1. Seed propagation:

A. Seed collection. When the small seeds turn yellowish brown in autumn, collect the mature seeds in time, dry them, remove impurities, put them in a cloth bag and store them in a dry and ventilated place.

B, raising seedlings. In spring, from March to April, and from September to November, a shallow trench (4mur6cm) was planted on a flat and raked seedbed with a row spacing of 15cm to 20cm. The sowing width was 10cm, and the bottom of the ditch was sprinkled with appropriate amount of ash, watering or thin human feces and urine, then evenly sprinkled with seeds mixed with fine soil, then sprinkled with a thin layer of fire ash or loess, and finally covered with straw and other mulch. The seedbed is often kept moist and generally germinates and emerges in about half a month. After emergence, remove the cover grass, strengthen the seedling stage management, the seedling height is about 5 cm and transplant into the field.

C, live. It is usually carried out in spring. On the finished border surface, the ditch is opened according to the row spacing of 30 cm, and the ditch depth is 3 cm. The seeds mixed evenly with fine fire soil ash or fine loess are scattered evenly into the ditch, covered with a thin layer of fine fertile soil, and then covered with grass to keep the soil layer moist. After about half a month, the seedlings emerged, after the seedlings were uncovered, the grass cover was removed, and the seedling stage management was done well, with a seed consumption of 1 kg per mu.

2. Ramet propagation: after harvest in autumn, the old mackerel will be dug up with whisker roots. The rootstock with strong growth and disease-free insects was selected and divided into several small ones, and then on the whole planting ground, the holes were dug according to the row spacing of 30 cm and the plant spacing of 7 mi. 10 cm, a small tree was planted in each hole, the soil was compacted after planting, and the thin human and animal dung water was applied, and the seedlings germinated the following spring.

3. Soil preparation and fertilization: ploughing the soil before planting, combined with soil preparation, apply 1 ton of rotten stable manure or compost, 25 kg of cake fertilizer or compound fertilizer per mu, and then make a high border with a width of 1.3 mi 1.5 meters, and open a good drainage ditch.

4. Transplanting: the seedlings raised in spring were transplanted from September to October in autumn, and those raised in autumn were transplanted from March to April in the following year. The horizontal trench was opened according to the row spacing of 25ml and 30cm, and one plant was planted every 7m and 10cm. The hole planting was planted according to the row spacing of 20 cm, and 1 plant was planted in each hole. After planting, the soil was compacted and watered thoroughly.

V. Field management

1. Ploughing, weeding and topdressing. When the seedling height is 1ml / 2cm, one thin human feces and urine water is applied in combination with weeding, and 1 ton per mu is applied as seedling fertilizer. When the height of the seedling was 3 Mel 4 cm, the seedlings were fixed and replenished according to the plant distance of 3 mi 4 cm, and then human feces and urine water was applied once respectively. For split propagation, when the new seedlings germinate, they should be combined with intertillage, weeding and topdressing for one time, and the field should be kept free of weeds. After each harvest, topdressing should be applied once to promote the germination of new branches and leaves. After the last harvest in November, winter manure was re-applied, 2 tons of rotten barnyard manure, cake fertilizer or 25 kg superphosphate per mu of manure, cake fertilizer or calcium superphosphate (25 kg), covering and cultivating soil after application, in order to keep warm and prevent cold.

2. Irrigation and drainage. Always keep the soil moist at the seedling stage and irrigate in time in case of dry season. Timely dredging and drainage in the rainy season to prevent stagnant water from flooding roots and seedlings.
