The latest course of cultivation techniques and methods of Solanum lyratum

Baiying is also known as mountain beet, white grass, wind grass, sky lantern, monk head grass and so on. It is a herbaceous vine of Solanaceae, which is native to China, and is also distributed in Japan, Korea and Indo-China Peninsula. it was first recorded in Shennong Materia Medica, listed as a top-grade traditional Chinese medicine, and let's take a look at the cultivation techniques of Baiying.

The growth habits of Radix Scutellariae

Baiying was born in valleys, grasslands or roadsides or fields at an altitude of 600-2800 meters above sea level. she likes a warm and humid environment, resistant to drought, cold and afraid of flooding. The requirement of soil is not strict, but it is better to use sandy loam soil which is deep, loose and fertile and rich in organic matter. Heavy clay, saline-alkali land and low-lying land are not suitable for planting.

The breeding method of Solanum lyratum

1. Seed reproduction: collect ripe fruits from October to December, soak them in 30-50 ℃ warm water for 24 hours, rub and rinse in clean water to remove pulp and impurities, then sow seeds immediately after drying, or mix seeds with 3 times of fine sand, store them in a cool place, and sow seeds in the following spring. Sowing from late March to mid-April is the most suitable, sowing or sowing in shallow trenches on the whole seedbed, and it can be transplanted after one year of cultivation.

2. Cuttage seedling raising: from the middle of April to the middle of May, select 1-2-year-old semi-lignified branches that are fully developed, robust and disease-free, cut the cuttings that grow 20-25 cm in the middle, leave 1-2 upper leaves, soak them in 500 × 10-6 acetic acid solution for 3 minutes, open ditches with a depth of 15-20 cm according to the row spacing of 40-50 cm, and cut them into the soil oblique every 7-10 cm, exposing the ground 1-2 cm-13 cm. The covering soil is compacted, watered and moisturized, it can take root in half a month or so, and it can be transplanted in autumn.

3. Ramet propagation: Bai Yingmeng has a very strong tillering ability. In autumn and winter, the underground root of the plant is dug out on the soil surface, cut the root bark, and covered with a small amount of fertile soil. The new seedlings can sprout in the next spring, and then dig and transplant with roots, and the survival rate is more than 95%.

Cultivation techniques of Solanum lyratum

1. Cultivation methods: Solidago mandshurica is usually cultivated on the ground from March to April in spring or from September to October in autumn, ditching according to the row spacing of 50: 70, with a depth of about 15 cm, planting a seedling according to the plant spacing of 7: 10 cm, planting straight and straight, covering the soil slightly higher than the original soil mark, watering enough fixed root water.

2. Fertilizer and water management: the growth of the seedlings is slow, and the weeds should be ploughed and weeded frequently at the initial growth stage, 4-5 times a year, the first time when the seedling height is about 5 cm, weeding is shallow loose soil, combined with the application of 1000-1500 kg fecal urine per mu of rotten soil to promote the seedlings to grow healthily, and then weed once a month. Irrigation and seedling protection should be carried out in the dry season, and ditch drainage should be carried out in time in the rainy season.

3. Set up a support: when the height of the seedlings is more than 30 cm, set up a support with bamboo poles or branches between the rows to pull the stems and vines to climb upward, improve the ventilation and light transmission conditions between the rows, enhance photosynthesis, promote the growth of stems and leaves, and help to increase production. The height of the frame is about 1.7 meters, and the two lines are connected by a crossbar to make it stable.

4. pest control: the leaves of Baiying are vulnerable to red spiders and aphids in summer, which can be killed with 3000 times of fenvalerate EC or 1000 times of 50% aphid pine EC or 1000 times of omethoate. At the same time, strengthen the comprehensive control of diseases and insect pests, and spray new high-fat membrane to enhance the control effect.

5. Harvest and processing: Bai Ying should do a good job of winter prevention and heat preservation at the end of autumn to ensure safe overwintering so as to ensure the growth of the coming year. Harvest the whole grass during the vigorous growth of stems and leaves in summer and autumn, harvest it twice a year, dry it directly after harvest, or wash it fresh.
