Precious medicinal plant yellow forest underplanting techniques
1 yellow queen
PolygoNatum sibiricum) is a lithography, known as yellow chicken head, ginger, chicken claw gin. Roots are commonly used as “yellow sperm”, which is used to replete the pulmonary pulmonary and vaginal effects, treats chronically ill, dry cough, thirst, sweat theft, mental fatigue, etc.; fresh roots contain reductive sugar that can be made of alcohol and sugar. Yellow sperm is more widely distributed in the south and is currently used for processing, mainly for the extraction of wild yellow sperm, thus accelerating the cultivation of yellow sperm。
1. 1 ecological practices
Most of these are found in forests, bushes, ditches, and streams; they are wet, cold-resistant, dry and seed-breeding and are suitable for cultivation under this unique habitat。
1. 2 cultivation techniques
1. 2. 1 landing. It is desirable to select the top floors of the land as a fully lumbered forest, bushes, grass and open areas under the forest, for example, in the form of corrosive, laxative, water-protected or sandy shades. The seeding is preceded by a deep one-time turn, combining the whole field with the farmer 's fattening, the ground 's base fatting, and then the sand is flat, the slopes are flat, and the length is 1. 2 m。
1. 2. 2 reproduction。
(1) root-shaped tubing. In late autumn or early spring, one to two years of healthy, insect-free roots were selected to select the precipice of the precipice, in sections ranging from 3 to 4 knots each, with the wound dryed slightly, at a distance of 22 cm x 15 cm and a depth of 5 cm, with a bit of squeezing and watering after the soil has been covered, and the soil wetted, and around 15 d. When planting at the end of the autumn, some fertilizers and grass should be covered after freezing。
(2) seed reproduction. When the august seed matures, it is collected, full of full maturity, and then treated with wet sand layering, until late march of the second year, when the seed is sifted out, spreads evenly within the shallows of the plume at 12-15 cm line range, covering approximately 1. 5 cm of soil, pouring water after a little pressure and keeping the grass wet. When the seed is 6-9 cm tall, it is suitable to move in a secret place, one year later。
1. 2. 3 management. Weeds should be ploughed in a timely manner, so as to be shallow and appropriate. The previous period, when combined with the medium-scale farming, was used to catch up with human and animal dung, and the latter period was used to catch up with farmers. During the rainy season, water should be drained in time to prevent accumulation。
1. 2. 4 harvest. Seed breeding and root breeding take place in 3-4 years and 1-2 years, respectively. In general, harvests take place before the onset of autumn and spring, and the roots of harvest are strong and full and of the highest quality at the end of autumn and early winter. After harvesting, the roots are removed from the ground and the stubble, the soil is washed, the steam cage is evaporated to the surface, the sun is dried or dried, or the water is boiled, and the sun is dried or dried。
