Seeds of cannabis.
Simeon’s hemp – suitable for sowing, should have humidity not above 13 %, normal colour for a kind and shine and whole covers without maculae, damages and fractures. The seed grain of a hemp received as a result of harvesting by a reaper or a combine, usually contains many admixings and has the raised humidity. Therefore after thrashing seeds are subject to pre-cleaning, drying, definitive clearing and sorting.
To preliminary clearing apply general purpose grain-cleaning machines ( 10, 20). Drying is effected on covered sheds where seeds scatter a layer in the thickness of 3-10 sm and periodically shovel to avoid self-warming. In crude weather and at the raised humidity of seeds it is recommended to apply grain driers with temperature not above 40-45. Definitive clearing is effected on OS grain cleaners 4,5, 5, etc.; sorting – on a pneumatic picking table (the PROGRAM STATUS WORD 1,5 or 2,5). On sowing qualities hemp seeds share on 3 classes, depending on weediness and germinating capacity (Germinating capacity see it is possible to define by sprouting of 1000 seeds. Seeds with germinating capacity below 75 % are considered as the sub-standard. The important indicator of quality of an inoculum – (mass of 1000 seeds) which should correspond to the parametres provided for the given kind. At hemp cultivars seeds compounds 9-26 g/1000 piece; at its decrease more low 8 g/1000 piece it is possible to draw breeding, that the given kind grows wild or degenerates. At feral forms (including a hemp weedy) seeds fluctuates from 2 to 8 g/1000 pieces According to researches of the Institute of bast crops, among seeds of the same kind large have higher germinating capacity, than small.
