Artificial pollination device for corn hybridization

Abstract

The invention discloses an artificial pollination device for corn hybridization, and relates to the technical field of crop cultivation. A bottom rod is fixed to the top of a ground rod, the bottom rod is of a hollow tube structure with a closed lower end, an adjusting screw is in screw joint with the interior of the bottom rod, the upper end of the adjusting screw is fixed to the lower end of a middle rod, an ejector rod is fixedly connected to the upper end of the middle rod through a plurality of springs, a support is fixed to the upper end of the top rod, the support is of a hollow tubularstructure with the two ends communicated with each other, a pollen outlet pipe and a pollen inlet pipe are communicated with and connected to the left end and the right end of the support respectively, the pollen outlet pipe and the pollen inlet pipe are each of an arc structure and a hollow tubular structure with the two ends communicated with each other, and one end of the pollen inlet pipe isin internal screw joint with the inner wall of the support through a screw joint end integrally formed with the pollen inlet pipe. Accordingly, one-to-many pollination can be conducted, and meanwhilethe pollination operation is simplified, and the pollination efficiency is effectively improved.

Description

technical field [0001] The invention relates to the technical field of crop cultivation, in particular to an artificial pollinator for corn hybridization. Background technique [0002] Because maize has unisexual flowers and cross-pollination, it does not need to be detasseled when hybridizing, so it does not need whole ears. The hybridization method and steps mainly include adjusting the flowering period, selecting plants, isolating, pollinating, pollinating and harvesting. [0003] In order to obtain purer corn, pollination and pollination of corn are generally carried out manually at present. The pollination and pollination of one plant will undoubtedly require more manpower and time. Pollination and pollination of plants can easily miss the best pollination period, affecting pollination quality. At the same time, before pollination, it is necessary to cover the ear with a kraft paper bag. When pollinating, the kraft paper bag is removed, and after pollination, the kraf...

Problems solved by technology

[0003] In order to obtain relatively pure corn, pollination and pollination of corn are generally carried out manually at present. The pollination and pollination of one plant will undoubtedly require more manpower and time. If the planting area is relatively large, simply one plant one Pollination and pollination of plants can easily miss the best pollination period, affecting pollination quality

At the same time, before pollination, it is necessary to cover the ears with a kraft paper bag. When pollinating, the kraft paper bag is removed, and after pollination, the kraft paper bag is put on again. This process is relatively cumbersome and needs to be improved urgently.
