Detailed Description

In order to facilitate understanding of the present invention, the following description is further provided with reference to the accompanying drawings.

As shown in fig. 1 and 2, the pollination sleeve bag disclosed by the utility model comprises a bag body 1, the bottom end of the bag body 1 is provided with a sleeve opening, the top end of the bag body 1 is provided with an opening, and the opening is used for observation or pollination; the upper part of the bag body 1 is provided with a rollback type structure, so that the upper part of the bag body 1 can be rolled and unfolded, and the purpose of observing or pollinating pistils without taking out the whole bag is achieved; the rewinding type structure comprises an elastic strip 2, and the elastic strip 2 is arranged at the upper part of the bag body 1; when the elastic strips 2 are rolled, the upper part of the bag body 1 is rolled, and the top opening of the bag body 1 is closed; when the elastic strip 2 is unfolded, the upper part of the bag body 1 is unfolded, and the top opening of the bag body 1 is opened. The elastic strip 2 is made of a material with certain plasticity or elasticity, and can achieve the effect of rolling and unrolling, such as rubber materials, plastic materials, metal materials and the like.

Specifically, when the elastic strip 2 is in a natural state, the elastic strip 2 is in a rolled state. Preferably, the end position of the elastic strip 2 can be rolled up by not less than 3 circles in the self-rolling state; adopt the elastic strip 2 that can be from rolling up, elastic strip 2 can be under its elastic force effect, and automatic the rolling up after the expansion is convenient for with bag body 1 expansion back to convenient operation improves work efficiency.

Specifically, the elastic strips 2 are respectively arranged on two sides of the bag body 1, and the upper ends of the elastic strips 2 are flush with the opening at the top end of the bag body 1; the elastic strips 2 are arranged inside the two sides of the bag body 1 and are adhered with the bag body. The elastic strips 2 are pre-embedded at the positions 3mm away from the edges of the two sides of the bag body 1 and are fixed with the bag cover in a bonding mode.

Specifically, the length of the elastic strip 2 is half of the length of the bag body 1, and in actual operation, the length of the elastic strip 2 used is adjusted according to the size of the pistil, and is not limited to be half of the length of the bag body 1.

One side of the self-adhesive tape 4 is a waterproof covering film, and the sealing and fixing after bagging can be carried out by tearing off during operation. The adhesive tape is used at the opening of the bag, so that the original fixing materials such as thin iron wires and silk threads can be well replaced, and the adhesive tape is adhered to branches more closely, so that the situation of hard mechanical contusion is avoided.

The utility model discloses when the actual application, there is following mode:

A. when the bag is sleeved, a pistil is selected, the sleeving opening (namely the lower end opening of the bag) is opened, the sleeving depth is good, and the protective film of the adhesive tape 4 is torn off, so that the sealing and the fixing after the bag is sleeved can be carried out.

B. During the observation, pull wire 3, until the complete expansion of the 1 upper portion elastic strip 2 of the bag body, with the bag top opening of cover part this moment opening be the viewing aperture promptly, the structure of rolling back stops the rollback temporarily, can observe through the opening. After the observation is finished and the mouth is opened, the elastic strip 2 is automatically rolled back or is manually rolled to finish the sealing.

C. During pollination, pull wire 3, until the complete expansion of 1 upper portion elastic strip 2 of the bag body, will overlap bag top opening and part this moment the opening be the pollination mouth promptly, the backrush structure stops the backrush temporarily, can carry out the pollination through the opening. After pollination is finished, kneading and opening, the elastic strip 2 is automatically rolled back or manually rolled to finish sealing. In addition, the secondary pollination operation is the same.

If the elasticity strip 2 of adopting can not carry out automatic rolling, can roll up bag body 1 upper portion through the mode of artifical rolling, pull 3 and expand bag body 1 upper portion, then observe or the pollination through the opening again.
