Seeds for sowing on an area of ​​15x 27 meters

 

Sale of elite seeds of Leuzea and Crowned Serpukha safflower - for the biosynthesis of ecdysterone, high quality (manual collection, drying in the sun, without diseases and pests.

Designed for the production of high-quality substances from the aboveground and underground parts of ecdysterone synthesizing plants Safflower Leuzea (Leuzea - ​​Rhaponticum carthamoides) and Serratula coronata.

1. Seeds of hand harvesting, sun drying, no puny seeds. Are not damaged by pests and do not have diseases. When sowing in winter, the seeds sprout immediately after the snow melts. They are not afraid of frost - they can withstand frosts up to -12 degrees without damage.

 

The quality of seeds for the synthesis of biologically active active substances (ecdysterone and their analogues): a) in the safflower leuzea - ​​up to 1.5%; in the crowned serrata - up to 4.7% (standard - 0.1%).

 

2. The seeding rate of seeds, taking into account their 4-5-fold stock per unit area, is 40-50 pieces per 3 m2. Layout scheme 70x5 cm, embedment depth 1-2 cm against the background of rolling. The optimum density of adult plants is 2.5-3.0 specimens per 1 m2 (for 5-10 years of life). It is recommended to sow with a reserve - to compensate for the death of seedlings and seedlings.

The productivity of 1 plant in dry form can be (maximum levels of aboveground phytomass): Leuzea 282-354 g on sandy loam, 444-525 g on peaty soils; in serpukha - 235-271 g on sandy loam, 197-252 g on peat bogs.

 

4. The phytomass of underground organs of 1 plant in dry form reaches 354-215 g in Leuzea, 103-83 g in Serpukha. nature 6500-7000 kg / ha). In serpukha, the value of above-ground production in dry form reaches 7600 kg / ha
