you are: Features of pollination of various cultures

Bees bring up to seed sites in 3-4 days after the flowering beginning 2-3 days prior to arrangement of bees a field semennikov lucernes obkashivajut, and in a file through each 500-600 m do cross-section proplaits. Beer families place round a seed field and on proplaits groups, till 50-60 families in group, providing counter pollination. pcheloopylenija lucernes apply the same ways of strengthening to efficiency increase letno-opylitelnoj activity of bees, as at pollination of a clover red. On 1 hectares of crops put 8-10 families of bees. The crop of seeds of a lucerne at pollination by its bees and use of other receptions agricultural technicians reaches 3-5 ts about 1 hectares.

Fodder beans - perekrestnoopyljaemaja and self-pollinated leguminous culture. TSvetki fodder beans reveal in second half of day, therefore are visited by bees mainly in the evening. The bee for one arrival visits to 250 tsvetkov. At sated pcheloopylenii the quantity of pods and weight of fodder beans increases. Productivity of beans about 1 hectares of continuous crops raises on 30-35%. Simultaneously bees collect on 18-30 kg of honey from this culture.

The Rank a sowing campaign - a leguminous agricultural crop. Cross-pollination and self-pollination is peculiar to it. TSvetki ranks plentifully allocate nectar, involving in a considerable quantity of bees and other insects. Main opyliteli ranks - melliferous bees. podvoz beer families to crops ranks are raised by a crop of this culture almost in 2 times in comparison with the crops isolated from bees.

Use of bees for simultaneous pollination of several agricultural crops. On fields of crop rotations can simultaneously take places grechiha and donnik, a clover and grechiha, donnik and sunflower. In all these combinations of an apiary place directly in the field of that culture which is visited by bees more poorly. At an adjacent arrangement of the cultures actively visited by bees, apiaries have between fields of these cultures. Quantity of beer families for pollination in similar cases establish on norm for culture with bolshej requirement.
