Embodiment Construction

[0016] Scion collection: select 1 mu of Junqianzi (soft jujube) with very low survival rate for grafting Japanese sweet persimmon. In early March, 2-3 weeks before the sprout of Japanese sweet persimmons, select robust, disease-free, 1-year-old branches to pick the scion, wax-sealed the bottom of the collected scion, and bury it in wet sand in a cool place for later use;

[0017] Choose the grafting time: choose the grafting time from late March when the rootstock Junqianzi (soft jujube) buds slightly to late April when the scion germinates, and the best time is mid-April;

[0018] Cut the rootstock: At the place where the rootstock Junqianzi is 5-10 cm away from the ground, on the side that is slippery toward the sun, make a flat cut downward, about 2 cm long, and then cut it vertically and horizontally below to remove the wood that has been cut, and a shape is formed underneath. Small slope

[0019] Cut the scion: Use a sharp knife to cut 1 cm above the scion bud, and cut a knif...

Abstract

The invention provides a method for grafting fruit tree seedlings in spring. The method comprises the following steps of collecting scions, choosing grafting time, paring rootstock, paring the scions, jointing, cutting the rootstock, erasing sprouts, dressing top, removing bundling substances, and the like. The method is characterized in that the scions are collected at the period of 2 to 3 weeks before germination in spring and are sealed with wax on the bottom on standby; when the rootstock slightly buds, one smooth side exposed to the sun is processed with a downward flat cut with the length of about two centimeters, and the underside of the rootstock is processed with a crisscross cut, so as to form a small oblique plane; a position one centimeter above the scion bud is processed with a downward flat cut with the length of about two centimeters, and then the underside of the scion bud is processed with a crisscross cut, so as to form another small oblique plane; the scions are pressed on the rootstock, the cambiums of the rootstock and the scions are aligned; the rootstock is shorn off at a position two centimeters above the scion bud 10 to 15 days after grafting; when the scion bud germinates, the sprouts of the rootstock are erased; and when a seedling is 20 to 30 centimeters high, the grafting bundling substances are removed. The method solves the problem that the grafting propagation of forest fruits is low in survival rate and high in cost, and is applicable to the grafting propagation of fruit trees.

Description

Technical field [0001] The invention relates to the field of seedling breeding, in particular to a spring grafting cultivation technique for fruit tree seedlings. Background technique [0002] At present, in the breeding and production of fruit tree seedlings, most traditional grafting methods such as split grafting and soil grafting are adopted, which have low survival rate, high cost and labor intensive. Summary of the invention [0003] In order to solve the problems of low survival rate, high cost and labor-consuming grafting of seedlings in fruit breeding and production, the invention invents a spring fruit seedling with xylem abdominal grafting, without bagging, wax sealing, and soil cultivation after grafting, which is simple and economical. Work, fruit tree grafting method with high survival rate. [0004] In order to solve the above technical problems, the present invention adopts a technical solution that is a spring grafting method for fruit tree seedlings. Its specia...
