The influence of protective coatings on quantitative
loss of garlic was investigated at its warm) and cold
storage under various conditions of relative humidity.
The following varieties of garlic people's selection
were studied: winter varieties – Tian Shansky, Otradnensky;
spring varieties – Sochinsky and Iglinsky Local.
Paraffin-ceresin composition (PK-1) was first proposed
as a protective hydrophobic coating of garlic
bulbs and its combination was scientifically based (the
main component is paraffin, plasticizer is Ceresin C-65
and surface-active supplement is a fraction of synthetic
fatty acids). Physical and mechanical performance
properties of PK-1: melting temperature 58 C; resistance
at 20 C 1,0 МПа; volumetric shrinkage 15%;
plasticity 0,5·10-4 1/МПа; water vapour permeability
6,5g/m2
per day.Waterproof properties of hydrophobic
protective coatings (paraffin-ceresin PK-1, alloy of
paraffin with beewax PК-4, paraffin without supplements
P) were compared with hydrophilic water solution
of polyvinyl alcohol PWS-5. According to the
increase of the moisture-proof properties, the investigated
coatings form the following series: P. PWS -5,
PК-4, PК-1. The maximum efficiency of garlic storage
under various temperature conditions and relative air
humidity was achieved when using a protection film of
PК-1. Compared with control (without coating) PК-1
reduced moisture loss in garlic bulbs for 3-13 times
depending on the variety, and storage duration of winter
garlic varieties increased for 2 times. Iglinsky Local
is the most moisture resistant of all the investigated
varieties, and Tian Shansky variety is less moisture
resistant
The influence of protective coatings on changes in the
biological characteristics of quality, germination, plant
growth and development of the onion crop quantitative
loss of garlic was investigated for the first time. The
objects of research were winter garlic called Tien Shan
and onion of Allan variety. Water solutions of polyvinyl
alcohol PWS-5, paraffin coating Ð , paraffin-cerezin
composition PK-1 were studied as a protective coatings.
Coating onions and chives before planting them
in the ground delay germination, respectively at 1 and
2 weeks. Then, protective coatings act as growth stimulants.
The greatest increase in green mass of garlic for
3 months (almost 2 times) compared to the control (uncoated)
prepared using the hydrophobic coating Ð K-1.
Ð K-1 increases the yield of garlic and onions in 1.5
times, and the seeds of onions in 1.3 times. It is recommended
before planting onions to cover onions the
PK-1 in order to prevent his fall germination and receive
further large bulbs weighing 130-131 g. Carbohydrates,
starch, vitamin C, and life-giving moisture
garlic, it is best stored in a Ð K-1 coated serve after
planting in soil more efficient power plant. As a result,
such plant grows better, develops and gives higher
yields
