Pollination preventing and capsule protecting mesh bag for cassava artificial hybridization

Abstract

The invention discloses a pollination preventing and capsule protecting mesh bag for cassava artificial hybridization. The mesh bag comprises a mesh bag body (1), a drawing rope (4), a transparent plastic film (5) and a hang tag bag (6). The mesh bag body (1) comprises a front layer and a rear layer, a cavity is formed in the middle, the two sides and the bottom end are closed, a mesh bag opening (3) is formed in the upper end, and air holes (2) are densely distributed in the mesh bag body (1). The drawing rope (4) is arranged on the upper portion of the mesh bag body (1). The transparent plastic film (5) is arranged between the mesh bag opening (3) and the drawing rope (4) in the mode of surrounding by one circle, and one part of the transparent plastic film (5) extends out. The hang tag bag (6) is arranged at the lower middle end of the bag face of the mesh bag body (1). The mesh bag can prevent pollination of media such as wind and insects after artificial hybridization is finished, prevent capsules naturally maturing from cracking and losing seeds, and protect the capsules against frost injuries and cold injuries of fog; bagging is carried out once till the capsules are harvested, and a great deal of time and labor can be saved.

Description

technical field [0001] The invention belongs to the technical field of agricultural implements, and in particular relates to a protective bag. Background technique [0002] Cassava hybrid breeding is the fundamental way to improve cassava varieties. In the process of cassava hybridization, the parents are selected for artificial pollination, and at the same time, the date of artificial pollination, the number of flowers, etc. are listed and registered. The bag covers the female flower, and then fixes it with a paper clip and a petiole or a petiole. However, there is no special anti-pollination bag for cassava on the market. If the above-mentioned technology is used, the main problems are as follows: 1. The kraft paper envelope bag only prevents wind pollination , Insects can enter from the lower end of the envelope bag, and it is not breathable at the same time, which may accelerate the loss of pollen vitality of the parents; 2. The kraft paper envelope bag is made of paper...

Problems solved by technology

In the process of cassava hybridization, the parents are selected for artificial pollination, and at the same time, the date of artificial pollination, the number of flowers, etc. are listed and registered. The bag covers the female flower, and then fixes it with a paper clip and a flower stalk or petiole. However, there is no special anti-pollination bag for cassava on the market. If the above-mentioned technology is used, the main problems are as follows: 1. The kraft paper envelope bag only prevents wind pollination , Insects can enter from the lower end of the envelope bag, and it is not breathable at the same time, which may accelerate the loss of pollen vitality of the parents; 2. The kraft paper envelope bag is made of paper material, which becomes soft and easy to rot when exposed to rain, which is not practical; 3. Pollination The hanging tags and hanging ropes after listing are easy to fall off or knotted after being exposed to wind and rain. Because the tags are usually hung on the flower stalks pollinated, sometimes the flower stalks will be broken, and the paper clips can only be fixed on the thinner flower stalks. And a little force may also break the flower stalk, if it is fixed on the branch, it will be easily deformed and cause it to fall off; 4. The kraft paper bag needs to be removed 3 days after pollination, because the paper bag is airtight and light-proof, if the bagging time is too long Long, easy to make pollinated flowers moldy in the bag, resulting in pollination failure

In order to prevent the capsule from bursting and losing seeds, agricultural science and technology workers usually pick the fruit in time when the capsule turns from green to yellow, but sometimes the fruit cannot be picked in time due to some reasons. At this time, the capsule will naturally mature and burst, and the popped seeds will be difficult to retrieve If the capsules are picked in advance, due to the inconsistent pollination time period, the maturity of each batch of capsules is also inconsistent, which will lead to insufficient maturity of some seeds and affect the germination rate of the seeds; if the capsules are harvested in batches, more time and labor will be wasted

[0004] In addition, frost is prone to occur in spring, and the morning dew and mist in the suburbs are heavy. In order to prevent spring frost and mist from frostbite cassava capsules, agricultural science and technology workers should always pay attention to Weather forecast, harvest the capsules in time to protect the capsules from frost and mist, but if the capsules are picked in advance, some seeds will not be mature enough, which will affect the germination rate of the seeds
