A kind of rapid seedling raising method of pear tree industrialization

Abstract

The invention relates to a quick industrialized seedling raising method for pear trees. The method comprises the steps of cultivation of stock seedlings, scion preparation, industrialized grafting andnursery stock conservation and conveying; good pear trees are selected as stocks and scions, the stocks and scions are prepared and placed in a low-temperature refrigerating chamber for use, a grafting operation platform is arranged in a workshop, and the platform is divided into a stock stacking area, a scion stacking area, an after-grafting nursery stock stacking area and a cut binding area; stock seedlings and scion seedlings are pruned before grafting; a double-tongue grafting method is adopted for the stocks and scions, grafting cuts are fused by candles, bound and then tied, and nurserystock variety labels are pasted; the grafted nursery stocks are placed in the refrigerating chamber for low temperature conservation, and the nursery stocks which need to be conveyed for a long distance are packaged and conveyed by selecting good-quality paper boxes. The industrialized grafting method has the advantages that the production efficiency is high, the survival rate of the nursery stocks is high, the nursery stocks grow quickly, the death rate in the conveying process is low, the cost is low, and quick propagation is achieved. The technical method is convenient to use, high in practicability, good in effect and broad in application prospect, saves labor and time and has a positive promotion effect on production of the nursery stocks of the pear trees.

Description

technical field [0001] The invention relates to the technical field of grafting and growing seedlings of fruit trees, in particular to a method for industrialized rapid seedling raising of pear trees. Background technique [0002] Fruit tree grafting is one of the methods of asexual reproduction of fruit trees, that is, to take branches or buds on a plant of a good variety and connect them to an appropriate part of another plant, so that the two can be combined to form a new plant; After completing this work, due to the influence of external weather changes, grafting period, seedling growth status, and terrain conditions on the outdoor seedling raising operations in the field, there are problems such as low seedling raising efficiency, poor uniformity of seedlings raised, and time-consuming and labor-intensive problems; existing foreign large-scale factories The chemical seedling raising method requires complex equipment and high cost, and is not suitable for the current fruit...

Problems solved by technology

[0002] Fruit tree grafting is one of the methods of asexual reproduction of fruit trees, that is, to take branches or buds on a plant of a good variety and connect them to an appropriate part of another plant, so that the two can be combined to form a new plant; After completing this work, due to the influence of external weather changes, grafting period, seedling growth status, and terrain conditions on the outdoor seedling raising operations in the field, there are problems such as low seedling raising efficiency, poor uniformity of seedlings raised, and time-consuming and labor-intensive problems; existing foreign large-scale factories The chemical seedling raising method requires complex equipment and high cost, and is not suitable for the current production of fruit tree seedlings in my country.

[0003] Existing pear tree grafting methods usually adopt skin grafting, bud grafting, cutting grafting, split grafting, abdominal grafting, etc., which have defects such as low grafting success rate and low survival rate, which not only increase the planting cost of fruit growers, but also take time and effort. The structure, hardness and sharpness of ordinary blades do not meet the requirements. In the process of cutting branches, the cutting plane is not neat, which is not conducive to healing, and the efficiency is low; wound dressing is important in the grafting process. A common method is to tie a knot with a plastic film, and then cut the plastic film, which is slow and time-consuming. When the seedlings are planted in the field, as they grow thicker, the interface plastic film will affect the growth of the seedlings. If the plastic film is not released in time, constriction marks will appear, which will limit the normal growth and development of the seedlings. After the grafting interface is completely healed, the plastic film needs to be untied in time. A knife is often used to cut the plastic film, but in the process of unbinding, it will cause damage to the plastic film. Some mechanical damage to seedlings is labor-intensive and time-consuming; grafted seedlings need to be stored in time, but during the storage process, problems such as mildew and rot are prone to occur due to excessive humidity; and seedlings are prone to dehydration and dryness during long-distance transportation , resulting in the death of the plants, or the poor ventilation in the box causes the seedlings to rot, which also causes the death of the seedlings, causing great losses
