Background technique

The currently used fruit bagging technology has played an important role in improving fruit appearance quality and reducing pesticide residues, and has been widely used in agricultural industries in various places. However, the bagging related technology in cotton breeding and boll preservation has not been reported at home and abroad.

Cotton in the southern cotton area of my country suffers from various diseases and insect pests, especially in Hainan, where cotton grows all year round. Because of the suitable climate, cotton bolls are particularly damaged by diseases and insects, such as aphids, cotton bollworms, red bollworms, weevils, and thrips. , Cotton Lygus, Cotton Pointed Bug, Cotton Blight, Red Rot, etc. Due to the resistance of pests and germs, the old cotton plants that grow all year round hide eggs and bacteria, which brings limitations to the control of diseases and insects with pesticides. In addition, insects (such as cotton bollworms, weevils, thrips, etc.) bite through the petals in many places. Cause cluster powder and cause outcrossing, resulting in impure varieties. Various unfavorable factors have seriously affected cotton breeding in the south, especially the multi-generation breeding of cotton in one year, the purification of cotton varieties, the innovation of cotton distant hybrid germplasm, the preservation of rare materials and the mining of cotton functional genes. The inventor noticed that the polypropylene non-woven fabric of appropriate thickness can effectively isolate cotton boll disease and insect damage, and reduce the amount of pesticide application, which has practical significance for reducing cotton boll disease and insect damage, protecting the environment, improving breeding efficiency, and implementing variety purification.

Utility model content

In order to achieve the above object, the technical solution adopted in the utility model is:

A cotton breeding bell bag, characterized in that it includes a square non-woven bag-shaped body, the two sides and the bottom of the body are sewn together, an opening is provided on the upper part, and the periphery of the opening includes a folded edge formed by folding outwards , the folded edge is connected with the body as a whole, a binding thread is threaded inside the folded edge, and the two ends of the binding thread protrude outside the folded edge; the length of the bag-shaped body is 10-12 cm, and the width is 13-15 cm. Its opening length is 6~8cm.

The non-woven bag-shaped body is specifically a bag-shaped component made of polypropylene resin material.

The non-woven bag-shaped body is a part stitched from non-woven fabrics with a specification of 75-80 g/m ² and a thickness of 0.16-0.18 mm.

The binding thread is cotton thread.

The cotton thread is a member made of colored material.

The bag-shaped body of non-woven fabric is also provided with a paper lining layer inside the non-woven fabric layer.

The beneficial effects of the utility model are: the utility model is a non-woven bag-shaped body made of polypropylene resin material, which has suitable flexibility, compactness, expansibility, air permeability, and water repellency. Just put it on the handle of the cotton boll, it is convenient and quick to operate, the overall structure is simple and reasonable, the manufacturing cost is low, and it is convenient for mass production. From the material and structure of the bag body, it can effectively isolate cotton boll disease, insect damage and mechanical damage, and reduce pesticides. Increase the application rate, improve the breeding efficiency, and solve the problem of impure varieties caused by outcrossing caused by cotton bunch pollination.

Below in conjunction with accompanying drawing and specific embodiment, the utility model is further described.

Detailed ways

Embodiment: Referring to Fig. 1 ~ Fig. 2, the cotton breeding bell bag provided in this embodiment includes a square non-woven bag-shaped body, the two side edges 3 and the bottom edge 4 of the body are sewn together, and an opening 1 is provided on the upper part. The periphery of the opening 1 includes a folded edge 5 formed by folding outwards. The folded edge 5 is integrated with the body. A binding thread 2 is inserted inside the folded edge 5. Both ends of the binding thread 2 protrude outside the folded edge. ; The length of the bag-shaped body is 10-12cm, the width is 13-15cm, and the length of the opening 1 is 6-8cm.

The non-woven bag-shaped body is specifically a bag-shaped component made of polypropylene resin material.

The non-woven bag-shaped body is a part stitched from non-woven fabrics with a specification of 75-80 g/m ² and a thickness of 0.16-0.18 mm.

The binding thread 2 is cotton thread.

The cotton thread is a member made of colored material.

The bag-shaped body of non-woven fabric has a paper lining layer inside the 6 layers of non-woven fabric, forming a double-layer structure with the non-woven fabric layer. The inner lining layer is in the shape of a sheet or a bag.

The cotton breeding bell bag provided in this example is made of non-woven fabric 6 with a specification of 75-80g/m ² and a thickness of 0.16-0.18mm to make the outer layer. There is a paper inner lining layer, the length of the non-woven fabric 6 is 20-24cm, and the width is 13-15cm.
