Problems solved by technology

Although this cultivation method can ensure rapid growth, deep roots and luxuriant leaves, fast fruit setting after grafting, and avoid the phenomenon of lack of plants in the field, open-field grafting requires high technical grasp and requirements, and is more susceptible to interference from external factors. Management and external insect vector hazards have a great impact on the survival rate of grafting, and the grafting rate has always been relatively low

Embodiment 1

[0025] 1. Experiments on the influence of seasons on the survival rate of grafting in the open field: in the four seasons of winter (January), spring (March), summer (July) and autumn (November), the pineapple Sakyamuni was grafted in the open field, and the grafting method The grafting method was adopted, and two buds were kept in the scion, and 100 plants with more consistent sturdiness were selected for each treatment of rootstock seedlings. After two months of grafting, statistics and investigations were carried out on indicators such as grafting survival rate and rootstock mortality rate of each treatment. Experimental observation found that the survival rate of grafting in spring was 82%, and the mortality rate of rootstock was 0; the survival rate of grafting in summer was 28%, and the mortality rate of rootstock was 33.3%; Rootstock mortality rate was 0.

Embodiment 2

[0029] A method for improving the grafting survival rate of Pineapple Sakyamuni, comprising the following steps:

[0030] (1) Selection of grafting season: The grafting work of Pineapple Sakyamuni is selected in mid-March.

[0031] (2) Selection of scions: select the branches of A.P pineapple Sakyamuni, which is annual and whose buds are still in the dormant stage, without diseases and pests, as the scions, with a thickness of 0.8-1.2cm. Since the buds of Pineapple Sakyamuni are all hidden in the base of the petiole, in order to promote the rapid germination of the scion buds, the petioles need to be manually erased during grafting to keep the two buds. The cold-resistant and disease-resistant "Lengzi" pineapple Shakya variety is selected as the rootstock. In terms of rootstock and scion matching, the scion is selected according to the thickness of the rootstock; the cutting method is adopted. The scion and rootstock incision thickness should not differ more than 0.2cm, and a...

Embodiment 3

[0036] A method for improving the grafting survival rate of Pineapple Sakyamuni, comprising the following steps:

[0037] (1) Selection of grafting season: The grafting work of Pineapple Sakyamuni is selected in mid-April.

[0038](2) Selection of scions: select the branches of A.P pineapple Sakyamuni, which is annual and whose buds are still in the dormant stage, without diseases and pests, as the scions, with a thickness of 0.8-1.2cm. Since the buds of Pineapple Sakyamuni are all hidden in the base of the petiole, in order to promote the rapid germination of the scion buds, the petioles need to be manually erased during grafting to keep the two buds. The common pineapple Sakyamuni variety with good cold resistance and disease resistance is selected as the rootstock, and the scion is selected according to the thickness of the rootstock in terms of rootstock and scion matching; the cutting method is adopted. The scion and rootstock incision thickness should not differ more th...

Abstract

The invention discloses a method for increasing open-ground grafting survival rate of Atemoya and belongs to the field of plant cultivation. The method includes the steps of 1), selection of grafting seasons; 2), selection of grafts; 3), field water management, namely controlling soil moisture to be 20% to 30% from 4 days before grating to 4 days after grafting, then performing appropriate surface soil water drenching and then normal water drenching after the grafts rupture films; 4), protection of graft unions; 5), timely unbinding. The method is simple in operation and low in cost, the problem about low survival rate in open-ground grafting of the Atemoya is solved, rapid growth of the plants can be guaranteed, seedling raising cost is lowered, new techniques and methods are provided for seedling raising production for the Atemoya, and a good application prospect is achieved.

Description

technical field [0001] The invention belongs to the field of plant cultivation, and in particular relates to a method for improving the survival rate of plant grafting in the open field. Background technique [0002] Pineapple custard apple (Atemoya) is one of the most economically cultivated tree species in the Annona family (Annonaceae), and it is a tropical and subtropical characteristic fruit tree. Its pulp is soft and smooth, with a unique and sweet flavor, rich in vitamin C and many nutrients, and has health care and medicinal functions such as beautifying the skin, strengthening bones, and enhancing immunity, so it is deeply loved by consumers. [0003] In recent years, with the serious spread of banana wilt in Guangxi and the instability of sucrose prices, the agricultural structure in traditional planting areas is in urgent need of transformation and development. Because the current market prospects for small tropical fruit trees such as pineapple and Sakyamuni are ...
