Problems solved by technology

[0004] Existing citrus seedlings usually have citrus seedling planting and grafted seedling planting. After planting, citrus seedlings have poor disease resistance, low fruit bearing rate, low yield, short service life and other defects; low survival rate, slow growth of seedlings, directly affect the production of citrus fruit trees

Embodiment 1

[0043]1) Selection of seedlings: The persimmon seedlings that emerged in the same year should be selected with a height of 0.8-1.4m and a thickness of 0.7-1.0cm. Before transplanting, soak the roots of the persimmon seedlings in clean water for 30 minutes, and then put them into the treatment solution. Soak for 20min;

[0044] 2) Transplanting. Plant persimmon seedlings in the middle and late March. When planting, dig a pit with a length, width of about 0.8m, and a height of 0.6m. The row spacing is 4×4m. After planting, pour nutrient water and fill with cover soil. After the persimmon seedlings survived, apply supplementary fertilizer, fill the supplementary fertilizer into the ditch, water and compact, and weeding;

[0045] 3) Management, when the seedling grows to about 1m, you can cut off the top branches of the persimmon seedlings, wrap the cut mouth with plastic cloth, and remove the plastic cloth when it germinates. When the persimmon tree blooms in the first year, prop...

[0058] 1) Selection of seedlings: The persimmon seedlings that emerged in the same year should be selected with a height of 0.8-1.4m and a thickness of 0.7-1.0cm. Before transplanting, soak the roots of the persimmon seedlings in clean water for 40 minutes, and then put them into the treatment solution. Soak for 30min;

[0059] 2) Transplanting. Plant persimmon seedlings in the middle and late March. When planting, dig a pit with a length, width of about 0.8m, and a height of 0.6m. The row spacing is 4×4m. After planting, pour nutrient water and fill with cover soil. After the persimmon seedlings survived, apply supplementary fertilizer, fill the supplementary fertilizer into the ditch, water and compact, and weeding;

[0060] 3) Management, when the seedling grows to about 1m, you can cut off the top branches of the persimmon seedlings, wrap the cut mouth with plastic cloth, and remove the plastic cloth when it germinates. When the persimmon tree blooms in the first year, pro...

[0073] 1) Selection of seedlings: The persimmon seedlings that emerged in the same year should be selected with a height of 0.8-1.4m and a thickness of 0.7-1.0cm. Before transplanting, soak the roots of the persimmon seedlings in clean water for 35 minutes, and then put them into the treatment solution. Soak for 25 minutes;

[0074] 2) Transplanting. Plant persimmon seedlings in the middle and late March. When planting, dig a pit with a length, width of about 0.8m, and a height of 0.6m. The row spacing is 4×4m. After planting, pour nutrient water and fill with cover soil. After the persimmon seedlings survived, apply supplementary fertilizer, fill the supplementary fertilizer into the ditch, water and compact, and weeding;

[0075] 3) Management, when the seedling grows to about 1m, you can cut off the top branches of the persimmon seedlings, wrap the cut mouth with plastic cloth, and remove the plastic cloth when it germinates. When the persimmon tree blooms in the first year...

Abstract

The invention discloses a stable yield-increasing breeding method for hybrid citrus grafting. The method comprises the following steps of (1) seedling selection, (2) transplanting, (3) management, (4)grafting and (5) management after grafting. The method has the excellent effects of easiness in industrial production, high growth speed, robust growth and excellent seedling quality, and is good ingrafting affinity, good in root development, high in water and fertilizer absorption capacity, easy to breed and high in grafting survival rate.

Description

technical field [0001] The invention relates to the field of planting technology, in particular to a breeding method for stably increasing yield of hybrid citrus by grafting. Background technique [0002] Citrus (Citrus reticulata Blanco) belongs to the Rutaceae plant. It likes a warm and humid climate, and its cold resistance is slightly stronger than pomelo, lime, and sweet orange. Rutaceae Citrus subfamily is distributed between 16°-37°N latitude. It is a tropical and subtropical evergreen fruit tree (except Citrus aurantium), and there are 3 genera used for economic cultivation: Citrus Citrus, Citrus and Kumquat. The citrus cultivated in China and other countries of the world is mainly of the Citrus genus. [0003] Rootstock plays the role of fixing, supporting the scion and delivering nutrients to the scion in the production of fruit trees. It is the basis for the cultivation of grafted seedlings and the key to the successful application of grafted seedlings in produ...
