Embodiment 1

[0027] The invention provides a method for assisting pollination of hybrid wheat by using an unmanned aerial vehicle. The specific steps are as follows:

[0028] When planting, the male parent and the female parent of the wheat are planted separately in different fields, and the pollen is collected and dried in the sun during the flowering stage of the male parent of the wheat, so that the water content of the pollen is 10%, and then stored in a freezer after drying;

[0029]Step 1. UAV equipment preparation: prepare UAV 1, pollen box 3, micro pump 4, pollination tube 5, electric valve 6, electric push rod 7, connecting rod 8, laser sensor 9, infrared emitter 10, infrared Receiver 11, blowing cover 12, first gear 13, small motor 14, second gear 15, small blower 16, flexible pipe 17 and distance sensor, pollen box 3 is fixed on the bottom of unmanned aerial vehicle 1 by bolt, and described miniature The pump 4 is fixedly arranged at the bottom of the pollen box 3, the inlet pip...

Embodiment 2

[0035] The invention provides a method for assisting pollination of hybrid wheat by using an unmanned aerial vehicle. The specific steps are as follows:

[0036] When planting, the male parent and the female parent of the wheat are planted separately in different fields, and the pollen is collected and dried in the sun during the flowering stage of the male parent of the wheat, so that the water content of the pollen is 15%, and it is frozen and stored after drying;

[0037] Step 1. UAV equipment preparation: prepare UAV 1, pollen box 3, micro pump 4, pollination tube 5, electric valve 6, electric push rod 7, connecting rod 8, laser sensor 9, infrared emitter 10, infrared Receiver 11, blowing cover 12, first gear 13, small motor 14, second gear 15, small blower 16, flexible pipe 17 and distance sensor, pollen box 3 is fixed on the bottom of unmanned aerial vehicle 1 by bolt, and described miniature The pump 4 is fixedly arranged at the bottom of the pollen box 3, the inlet pip...

Embodiment 3

[0043] The invention provides a method for assisting pollination of hybrid wheat by using an unmanned aerial vehicle. The specific steps are as follows:

[0044] When planting, the male parent and the female parent of the wheat are planted separately in different fields, and the pollen is collected and dried in the sun during the flowering stage of the male parent of the wheat, so that the water content of the pollen is 20%, and then stored in a freezer after drying;

[0045] Step 1. UAV equipment preparation: prepare UAV 1, pollen box 3, micro pump 4, pollination tube 5, electric valve 6, electric push rod 7, connecting rod 8, laser sensor 9, infrared emitter 10, infrared Receiver 11, blowing cover 12, first gear 13, small motor 14, second gear 15, small blower 16, flexible pipe 17 and distance sensor, pollen box 3 is fixed on the bottom of unmanned aerial vehicle 1 by bolt, and described miniature The pump 4 is fixedly arranged at the bottom of the pollen box 3, the inlet pi...

Abstract

The invention discloses a method for carrying out supplementary pollination on hybrid wheat by applying drone, and particularly relates to the technical field of agriculture, which comprises the following specific steps of: 1, preparing drone device; step 2, planning; 3, taking off; step 4, positioning pollination: after the laser sensor aims at the pollination position of the plant, the drone stops at the pollination position, and pollen falls down for positioning pollination of the plant; and step 5, large-area pollination: when the pollen is sprinkled, the small blower generates wind powerto blow out through the blowing cover, and meanwhile, the sprinkled pollen is blown in a large area by adjusting the blowing direction of the blowing cover. The method effectively solves the prominentproblems of labor shortage in hybrid wheat seed production, scale and cost in large-scale production and the like by using the drone for supplementary pollination, can be widely applied to hybrid wheat seed production, has the functions of positioning pollination and large-area pollination, can be reasonably selected according to actual operation, and is wide in application range and high in pollination efficiency.

Description

technical field [0001] The embodiment of the present invention relates to the field of agricultural technology, in particular to a method for assisting pollination of hybrid wheat by using an unmanned aerial vehicle. Background technique [0002] At present, the two-line hybrid wheat mainly adopts the row ratio method or the mixed sowing method to produce hybrid wheat seeds. Previous studies have shown that the mixed sowing method has a wider application prospect because of its high and stable seed production yield. Mixed sowing seed production is based on the characteristics of the male parent and the size of the sowing amount, mixing the male parent's seeds into the female parent's seeds in a reasonable proportion for mixed sowing, and using related supporting technical links for hybrid seed production. This method requires that the plant height of the male parent must be higher than that of the female parent by more than 15cm. However, labor costs are high in the proces...
