Embodiment 1

[0046] A cocoa artificial cross-pollination method, which uses plexiglass tubes, nylon nets, plastic-coated iron wires, etc. to make hybrid casings (for the structure see figure 1 ), the flower buds of the selected cocoa parents were isolated by casing, and the hybrid fruit was obtained by artificial emasculation. The operation method and steps are as follows:

[0047] 1. Preparation of hybridization casing

[0048] Cut a plexiglass tube with an outer diameter of 3 cm into a cylindrical shape with a length of 8 cm, and drill two symmetrical round holes 1 cm from both ends of the glass tube. Cut the 60-mesh nylon mesh into a 10cm×10cm square, cover one end of the cylindrical plexiglass tube with the cut nylon mesh, and fix it with plastic-coated iron wire along the drilled hole. Two long 40cm plastic-coated iron wires are symmetrically tied at one end of the cylindrical plexiglass tube.

Embodiment 2

[0059] The invention discloses a cocoa artificial cross-pollination method, which uses a plexiglass tube, a nylon net, a plastic-coated iron wire, etc. to make a hybrid sleeve, isolates selected cocoa parent flower buds with the sleeve, and adopts the method of artificial emasculation to obtain hybrid fruits. The operation method and steps are as follows:

[0060] 1. Preparation of hybridization casing

[0061] Cut a plexiglass tube with an outer diameter of 2.5 cm into a 7 cm long cylinder, and drill two symmetrical round holes at a distance of 0.8 cm from both ends of the glass tube. Cut the 60-mesh nylon mesh into a square of 8cm×8cm, cover one end of the cylindrical plexiglass tube with the cut nylon mesh, and fix it with plastic-coated iron wire along the drilled hole. Two long 40cm plastic-coated iron wires are symmetrically tied at one end of the cylindrical plexiglass tube.

Embodiment 3

[0072] In order to illustrate the hybridization accuracy of the present invention, the seed setting rate of cocoa emasculated pollination and emasculated non-pollination was compared. The operation method and steps are as follows:

[0073] 1. Preparation of hybridization casing

[0074] Cut a plexiglass tube with an outer diameter of 2.5 cm into a 7 cm long cylinder, and drill two symmetrical round holes at a distance of 0.8 cm from both ends of the glass tube. Cut the 60-mesh nylon mesh into a square of 8cm×8cm, cover one end of the cylindrical plexiglass tube with the cut nylon mesh, and fix it with plastic-coated iron wire along the drilled hole. Two long 40cm plastic-coated iron wires are symmetrically tied at one end of the cylindrical plexiglass tube.

[0075] 2. Select parent book

[0076] Select cocoa single plants TAS118, TAS167, TAS414, and TAS1519 with healthy growth, stable and high yield, excellent quality traits, and relatively consistent flowering period as t...

Abstract

The invention relates to the technical field of agricultural breeding, in particular to a hybrid casing pipe and an artificial hybrid pollination method for cacao. The hybrid casing pipe comprises a barrier net 1, a transparent pipe body 4 and a colligating device 6; the barrier net 1 covers an opening in the upper end of the transparent pipe body 4, and the colligating device 6 is arranged at thelower end of the transparent pipe body 4. The hybrid casing pipe and the artificial hybrid pollination method can guarantee effective pollination of the cocoa, solve the problem that cocoa flowers are not easy to physically isolate due to mainly growing on a trunk, and improve a fertility rate after pollination, and the hybrid casing pipe effectively protects hybrid young fruits of the cocoa fromoutside damage, and is very convenient to operate in the fields.

Description

technical field [0001] The invention relates to the technical field of agricultural breeding, in particular to a hybrid casing and a cocoa artificial hybrid pollination method. Background technique [0002] Cocoa seeds are rich in cocoa butter, flavonoids, theobromine and dietary fiber. They taste mellow and have health effects such as improving heart, kidney, intestinal function and relieving angina pectoris. They are the main raw materials for making chocolate, beverages and cakes. In addition, cocoa The pulp is sweet and sour, with a unique flavor. It can be eaten fresh or processed into fruit juice, fruit wine, etc. It has high economic value and is known as "the food of God". Cocoa is native to the tropical rainforest of South America, and there are 22 species in the world, among which cocoa and large-flowered cocoa have been commercially planted on a large scale around the world. [0003] At present, the world's cocoa harvest area reaches 10 million hectares, with a t...
