Description

Rape hybridization and selfing bag

Technical Field

The utility model belongs to crops breeding field especially relates to a rape hybridization, selfing bag.

Background

Crop breeding is a technology for creating new germplasm resources and breeding new varieties by creating genetic variation and improving genetic characteristics. Common breeding methods include crossbreeding, pure line breeding and the like, and are widely applied to crops such as rice, corn, rape and the like at present. To successfully complete breeding, the pollination isolation bag is an essential tool. The inflorescence after the plant blooms or after castration needs to be immediately bagged to avoid pollution caused by pollination of other foreign pollen. The bagging isolation can effectively avoid the foreign pollen channeling phenomenon.

At present, a pollination isolation bag for rape breeding is a flat waterproof parchment paper or a textile cloth bag, and one side of the pollination isolation bag is an open end and the other side of the pollination isolation bag is a closed end. Need prepare the tearing membrane of time shape needle or suitable length before the cover bag, need strut the container bag during cover bag to have sufficient space complete and put into the bag with the inflorescence top with not breaking, later will strut the container bag slowly down the cover from the rape is top, and reserve one section plant growth space between top and container bag blind end, seal in suitable position, seal and have two kinds of modes: one is to seal the opening by using a tearing film, wherein the opening end needs to be pinched into one strand by hand during sealing, and then the tearing film is used for winding and tensioning the opening end; the other is to use a paper clip to seal, and the opening end needs to be folded upwards and then fixed by the paper clip when sealing.

The following seven aspects of the isolation of selfing bags using traditional hybridization bags exist: (1) when in use, the paper bag needs to be spread, and then the paper clip or the tearing film is used for sealing the opening, so that the operations are not only complicated, but also take more time; (2) the rape is an unlimited inflorescence, and as the plants grow, the subsequently opened flowers are stacked at the closed end of the isolation bag, but the closed end of the isolation bag is flat, so that the expandable space is small, and pollination fructification of the later opened flowers and growth and development of early pollination fruits are not facilitated; (3) after bagging, the isolation bag needs to be lifted up periodically to ensure that enough space is provided for inflorescence extension and paper bag penetration is avoided, but because the lower part of the bag body is fixed by the clip and the tearing film, the bag needs to be unfastened every time the bag is extracted, and the bag is fixed after being lifted, so that the management operation is complicated; (4) the bag needs to be taken off at the later stage to be beneficial to the development of the siliques and the seeds, but the closed end of the paper bag is difficult to judge whether the flowering phase is finished, and the closed end of the paper bag needs to be close to and lifted, so that the operation is complicated; (5) after bagging, the bottom of the bag is completely sealed and fixed by a tearing film or a clip, petals of the bag gather at the bottom of the bag body after falling off along with the growth of plants, and if the bag cannot be extracted in time, pathogenic bacteria are easy to enrich and grow at the position, the development of the plants is damaged, and selfing or hybrid harvesting failure is caused; (6) when selfing bagging is carried out, in order to harvest enough seeds, the whole plant is often bagged, but because the size of the isolation bags is limited, two large isolation bags are overlapped and sleeved together, if the two bags are not well processed at the connection position, after the plant grows high, the connection part of the bags is separated, partial buds are exposed, and if the bags cannot be connected again in time, other pollen falls on the exposed part of the column heads, so that the seeds are impure; (7) at the end of the flowering phase, the tearing film and the paper clip used for fixing the bag body are usually discarded/abandoned in the field when the bag is taken off, which wastes resources and pollutes the soil environment.

In general, the use of flat waterproof sulfuric acid paper bags is not only cumbersome to operate but also time-consuming and labor-consuming. Therefore, how to simply and conveniently collect the hybridization bag in the process of rape hybridization or selfing is a technical problem to be improved.
