The invention belongs to the fields of fruit tree cultivation and pollination, and in particular relates to a high-activity pollen suspension used for spray pollination of Korla fragrant pear trees and a preparation and pollination method thereof. The highly active pollen suspension of the invention is made from purified water, white sugar, boric acid, calcium nitrate, xanthan gum and Korla fragrant pear pollen. Utilizing the technology of the present invention can effectively solve the problems such as low pollen utilization rate, poor pollen activity, poor pollination effect, and poor fruit setting due to the pollen not being evenly dispersed in the aqueous solution in the process of liquid spray pollination of Korla fragrant pear fruit trees, and ensures the best results in fruit trees. During the best pollination period, the pollination work can be completed in time and quickly, realizing efficient artificial pollination of pear trees, and greatly improving the efficiency and quality of pollination work. Through the production application test, the inflorescence fruit setting rate is increased from the original 38.9% to 71.5% after the technology of the invention is adopted, and the improvement rate reaches 83.8%, a good pollination effect is obtained, and the goal of high yield is realized.

Breeding method of high-oil-content disease-resistant brassica napus germplasm

The invention belongs to the technical field of brassica napus breeding and discloses a breeding method of high-oil-content disease-resistant brassica napus germplasm. The breeding method of the high-oil-content disease-resistant brassica napus germplasm comprises the following steps: selecting a high-oil-content brassica napus cross parent, performing primary hybridization, conducting optimal selection and impurity removal on primary hybrid seeds, selecting a second-generation cross parent, conducting second-generation hybridization, and conducting selfing on second-generation hybrid seeds. High-yield and high-oil-content brassica napus seeds are cultivated through hybridization, disease resistance of the brassica napus is enhanced through the secondary hybridization, and the high-oil-content disease-resistant brassica napus is obtained. The provided breeding method of brassica napus is simple. The obtained high-yield and high-oil-content brassica napus seeds have characteristics of high yield, high oil content and strong disease resistance. Quality and planting benefits of brassica napus can be improved. A detection shows that the oil content of the high-oil-content disease-resistant brassica napus has the oil content higher than 48%.

An agricultural pollination drone with high pollination rate

The invention belongs to the technical field of agricultural unmanned aerial vehicles, and in particular relates to an agricultural pollination unmanned aerial vehicle with high pollination rate. One end of the air pipe is provided with an air inlet, and the other end is provided with an air outlet. Both the air inlet and the air outlet are arranged in a funnel-shaped opening. The outer rotation of the air pipe is connected with a permanent magnetic ring. The pollen box The inner top surface of the air duct is provided with a driving mechanism for driving the rotation of the permanent magnet ring. A fan is rotatably connected to the inner wall of the air duct, and the two opposite blades of the fan are made of magnetic materials and are connected with the permanent magnet ring. Different poles attract each other, and the side wall of the air duct is fixedly communicated with a plurality of equidistantly arranged suction pipes. In the present invention, the pollen is fully mixed with air and then sprayed out, the pollination effect is good, and the pollen is prevented from being directly agitated by the fan blade to cause damage, the temperature of the pollen is continuously reduced through the cooling tube, and the pollen activity is prevented from being affected by the temperature rise in the pollen box.
