Unmanned aerial vehicle pollination device for strawberry facility cultivation

Abstract

The invention discloses an unmanned aerial vehicle pollination device for strawberry facility cultivation. The unmanned aerial vehicle pollination device comprises an unmanned aerial vehicle and a pollen collection and pollination device, the pollen collection and pollination device comprises a shell, a micro-motor, an electrostatic generator, a hemline filament set, a controller and a humidifier,two symmetric sides of the shell are rotatably connected on the lower portion of the unmanned aerial vehicle through hanging rods, the micro-motor is mounted at the top of the shell, an output shaftof the micro-motor is fixedly connected with the shell, the electrostatic generator is mounted at the bottom of the shell, one end of the hemline filament set is fixed onto the surface close to the bottom of the shell along a peripheral direction, the controller and the humidifier are mounted in the shell, an unmanned aerial vehicle power supply is electrically connected with the controller and the micro-motor, and the controller is electrically connected with the electrostatic generator and the humidifier. The device effectively overcomes the problems of low pollination rate, high fruit malformation rate and the like of strawberries under conditions of low temperature and weak light, intelligent alienated pollination of facility strawberries is achieved, and the device is simple in structure and easy to operate.

Description

technical field [0001] The invention relates to the technical field of agricultural pollination equipment, and more specifically relates to an unmanned aerial vehicle pollination device for facility cultivation of strawberries. Background technique [0002] The flowering and fruit setting period of strawberry cultivated in facilities is as long as more than 6 months, and it has the characteristics of continuous flowering and fruit setting. Among them, pollination is the key link to ensure the yield and quality of strawberry. [0003] Strawberry flowers belong to monoecious complete flowers, and the yield and quality of cross-pollination are better than self-pollination. The strawberry inflorescence is a dichotomous cyme, the low-level inflorescence pistil has a high pollination rate, and the high-level inflorescence stamen cracking and pollination rate are high and are affected by temperature. Strawberries cultivated in facilities generally bloom from October to April of the...

AI Technical Summary

Problems solved by technology

However, the above equipment and methods are suitable for dioecious hermaphrodite flowers, and cannot be applied to the characteristics of monoecious complete flowers.

The patent (CN201320558641.X) proposes a solar greenhouse track-type automatic pollinator, which has the combined functions of reciprocating operation, wind force and mechanical vibration pollination, and can realize the automation of the pollination process of greenhouse cultivated crops, but it cannot satisfy the double-row planting method of strawberry plants , the characteristics of dichotomous cymes and the requirements of cross-pollination, and the mechanical vibration is easy to damage the stems and leaves of plants. The suitable temperature for strawberry pollination is 20-25 ℃, and the relative air humidity is about 70%. Difficulty in anther cracking, poor pollen development, and reduced pollination success rate

At present, there are no research reports on UAV pollination equipment and technology for facility strawberries
