Method for fertilizing hybrid paddy rice for seed production by applying multi-rotor-wing remotely piloted vehicle

Abstract

The invention discloses a method for fertilizing hybrid paddy rice for seed production by applying a multi-rotor-wing remotely piloted vehicle. The method applies the multi-rotor-wing remotely piloted vehicle for hedgehopping to agitate air above a field parcel for the seed production of the hybrid paddy rice, and a formed local low-energy air eddy helps paternal pollens to be blown off among maternal rows, and is convenient for maternal stigmas to accept more paternal pollens, so that an outcrossing setting percentage can be increased by 1.2-2.5%. The multi-rotor-wing remotely piloted vehicle in the method for fertilizing the hybrid paddy rice for the seed production by applying the multi-rotor-wing remotely piloted vehicle continuously flies back and forth in a transverse W shape as a flight path relative to the field parcel for the seed production of the hybrid paddy rice, and repeatedly flies for 3-6 times above a same field parcel at time intervals of 10-20 minutes each time and at flight heights of 2-8 meters. As an area, which is influenced by the eddy generated by the hedgehopping of the multi-rotor-wing remotely piloted vehicle, of a ground target field parcel for the seed production of the hybrid paddy rice is large, parental row ratios are increased to 3:(24-42); the work efficiency of vast continuous fertilization is 10-15 times higher than that of manual flower pulling fertilization; thus, the labor cost is saved massively. The method for fertilizing the hybrid paddy rice for the seed production by applying the multi-rotor-wing remotely piloted vehicle is particularly suitable for being used by an enterprise carrying out large-scale seed production.

Description

Technical field [0001] The present invention relates to a method for pollination of crops, in particular, the present invention relates to a method for pollination of hybrid rice seed production, in particular to the application of a multi-rotor remote control aircraft as a method for pollination of hybrid rice seed production. Background technique [0002] In order to improve the purity and yield of hybrid rice female parents, the seed production industry usually implements artificial pollination operations on hybrid rice female parents grown in the field to increase the outcrossing seed setting rate. Artificial pollination is a technically demanding and labor-intensive agricultural operation. With the development of agricultural science and technology, the seed production industry has also been greatly developed. The large-scale seed production industry is used for seed production. The acreage is large and wide, and manual pollination can no longer meet the production needs. Co...
