Problems solved by technology

However, there are few relevant reports on grafting as an important link in the breeding of fine cocoa seedlings.
The grafting method used in very few foreign reports is the same as the common grafting method, that is, a scion is cut from the branch of the mother tree, inserted into the incision on the rootstock, and tied to make it close and healed. In the grafting of cocoa seedlings, the phenomenon of low survival rate is prone to occur, and the growth status of the surviving cocoa seedlings is also poor. At present, there is no method suitable for grafting cocoa seedlings

Embodiment 1

[0030] Embodiment 1: breeding method of the present invention

[0031] Select healthy cocoa seedlings with strong growth, high branch position, and no pests and diseases as rootstocks, top the rootstock one week before grafting, keep 3-5 leaves, and keep the surface of the rootstock branches dry before budding;

[0032] Collect the semi-lignified scion branches of the year, cut off the leaves on the scion branches, keep the petioles, and wrap them with a wet towel to keep them moist; Make a ring cut, and then make a vertical cut on the left and right sides of the dormant bud. The scion is 0.8cm to 1.5cm long, 0.5cm to 1cm wide, and the depth just reaches the xylem; gently pull the petiole on the scion with your index finger and thumb to peel it off from the xylem;

[0033] Make a smooth rectangular incision at a relatively straight place 10cm to 15cm away from the ground. The depth is just to see the xylem, whichever fits with the scion. Make an incision so that the scion cam...

Embodiment 2

[0035] Embodiment 2: Survival rate statistical test

[0036] Carry out the contrast of grafting survival rate with existing method and the method of the embodiment of the present invention 1 method, two kinds of methods adopt identical cocoa seedlings as rootstock, and pre-grafting branch adopts the cocoa branch of germplasm numbering listed in Table 1, and existing method Only difference with embodiment 1 method is that the rootstock sheet of its cutting breaks away from rootstock completely, is not connected with the bottom end of incision, and the petiole on the scion is not retained. The test results are shown in Table 1.

[0037] Table 1 Statistical results of grafting survival rate

[0038]

[0039] It can be seen from the above table that the number of cocoa seedlings grafted and survived according to the breeding method of the present invention is obviously more than that of the cocoa seedlings grafted by the existing method, and at the same time, it is also superi...

Abstract

The invention relates to the technical field of agriculture, and discloses a cultivation method of cocoa seedlings. The method comprises the steps that pre-grafted cocoa branches are firstly manufactured into cions; stock pretreatment is carried out; a rigid xylem notch is formed in a base portion of each stock, in the notch forming process, cut stock sheets are made to be only connected with the bottom ends of the notches, the cions are embedded into the notches, cion forming layers are aligned at stock forming layers, then the cut stock sheets are compressed on the cions, sprout points are exposed, and the cions and the cut stock sheets are bound with the combination positions of the icons and the stocks; cion coalescence is carried out for three weeks, binding is removed, cion coalescence is carried out for four weeks, the portions, 5 cm above the notches, of the stocks are sheared off, sprouts growing on the stocks are removed in time after cion coalescence, and the grafted cocoa seedlings are obtained after three months. Through the operations of cion and stock treatment adjusting in an existing grafting method, a stock notch treatment method, management carried out after cion embedding and the like, the defect that the survival rate in the existing method is low is overcome, and new technical supports are provided for cocoa seedling cultivation.

Description

technical field [0001] The invention relates to the field of agricultural technology, in particular to a method for breeding cocoa seedlings. Background technique [0002] Cocoa (Theobromacacao L.) is an evergreen tree species of cocoa belonging to the family Sterculiaceae. It is one of the three major beverage crops in the world. It is rich in nutrition, mellow in taste, and has exciting and nourishing effects. It is the main raw material for making chocolate, beverages, pastries, etc. , suitable for planting in Hainan Province of my country. The world's cocoa harvest area reaches 10 million hectares, with a total output of over 4 million tons. Domestic cocoa beans mainly rely on imports. In 2012, the import volume was more than 230,000 tons, and the annual growth rate increased by 15%. With the continuous improvement of people's living standards and changes in dietary structure, the market demand for cocoa beans will continue to increase. At the same time, cocoa is a typi...
