The sunflower blossoms two weeks. Daily from periphery to the basket centre two-three numbers tsvetkov are dismissed. Usually tsvetki 2 days remain, for the second day they become capable to fertilisation and are pollinated. At a lack opylitelej flowering can be tightened, that will lower ability tsvetkov to fertilisation.

On size of a crop of sunflower the big influence renders a saturation of crops by bees. At placing on 1 hectares of crops to 0,25 beer families the crop makes 11,8 ts, at placing on 1 hectares of crops of 0,7-1,0 families the crop raises to 16,7 ts. For effective pollination of sunflower it is necessary to bring up in due time bees to crops from calculation 0,5-1 beer family on 1 hectares. Glut of number of families on unit of the area of crops gives an insignificant increase of a crop. The greatest attendance of sunflower bees with 10 to 16 ch.

The Room. Efiromaslichnaja culture, from which bee collect nectar and pollen. Usually they visit mustard in the morning (9-11. For effective pollination of this culture it is enough to bring up and place 0,5-1 family of bees on 1 hectares of crops. Pollination by bees gorchitsy increases zavjazyvaemost pods and formation of seeds depending on high-quality features of culture by 12-50%.

The Coriander. Efiromaslichnaja the culture, gives to bees nectar and pollen. It is well visited by bees during the period between 10 and 15 ch. Bees bring up to a pollinated site from calculation of 2 families on 1 hectares of crops. Families are better for placing groups round a blossoming file.

Pollination by bees raises a crop and others olive and efiromaslichnyh cultures, including rapsa winter and summer. Bees well visit these cultures. Terms podvoza and ways of arrangement of apiaries at their pollination the same, as for all cultures well visited by bees.

The Cotton. TSvetki a cotton are capable to self-pollination, but cross-pollination appreciably raises a crop of seeds and a fibre and improves a clap-raw rating. Fine-fibered grades of a cotton plentifully allocate nectar and are well visited by bees. At pollination by bees tsvetkov a cotton the weight of a box increases by 12-18%, number of seeds - on 6%, weight of seeds - on 3-8%, weight of a cotton fibre - on 40%. Pcheloopylenie accelerates maturing of fruits for 5-9 days in comparison with self-pollinated tsvetkami.

For pollination of a cotton of an apiary bring up to the pollinated area and place 5-6 families of bees on 1 hectares of crops. At weak visiting of a cotton them train by means of the flavoured top dressing.

Flax-dolgunets. It is capable to self-pollination, but it can be pollinated perekrestno. Use of bees on flax pollination gives a considerable increase of a crop. At self-pollination in 500 boxes 2902 grains are, at pollination by bees - 3393 grains. The weight of 1000 grains accordingly makes 5,15 and 5,28 For the best pollination of culture of bees train.
