Problems solved by technology

[0003] Apple planting technology in many areas, the use of propagated apple seedlings for artificial cultivation generally has problems such as poor tree shape and low fruit yield, apple dwarf stock, good grafting compatibility with most apple varieties
It has obvious advantages such as dwarfing, high yield, cold resistance, disease resistance, and waterlogging tolerance. At present, tissue culture is mainly used to raise seedlings in China, and its cost is very high, which seriously limits the popularization and application of apple dwarf fruit trees.

Embodiment 1

[0015] An apple dwarfing cultivation method is characterized in that, comprising the following steps:

[0016] (1) Young shoot treatment: select dwarf apple seedlings with strong branches, cut 16cm young shoots, and soak the bottom 5cm with a rooting solution composed of MS vitamins + 1000ppm IBA + 1000ppm NAA with a pH of 5.2;

[0017] (2) Making nutrition bags: put the nutrient soil with a weight ratio of clay: peat of 5:2 in the polyethylene bag, put the treated young shoots into the nutrition bag, and keep the moisture content of the nutrition bag matrix at 65% ;

[0018] (3) Transplanting: When the seedlings grow new roots to yellowish brown, trim off the leaves at the base of the apple seedlings, leaving only 3-5 leaves at the tip of the stems, plant them at a plant-to-plant distance of 1m, and a row spacing of 2m, and pour enough water for rooting;

[0019] (4) Pruning and shaping: When the apple grows to a height of 1m, pinch the top and remove the top advantage of th...

Embodiment 2

[0021] An apple dwarfing cultivation method is characterized in that, comprising the following steps:

[0022] (1) Young shoot treatment: select dwarf apple seedlings with strong branches, cut 18cm young shoots, dip the bottom 6cm into rooting solution with a pH of 5.5 consisting of MS vitamins + 1000ppm IBA + 1000ppm NAA;

[0023] (2) Making nutrition bags: put the nutrient soil with a weight ratio of clay: peat of 5:2 in the polyethylene bag, put the treated young shoots into the nutrition bag, and keep the moisture content of the nutrition bag matrix at 75% ;

[0024] (3) Transplanting: When the seedlings grow new roots to yellowish brown, trim off the leaves at the base of the apple seedlings, leaving only 3-5 leaves at the tip of the stems, plant at a plant spacing of 1.2m, and a row spacing of 2.3m, and pour enough water for rooting;

[0025] (4) Pruning and shaping: When the apple grows to a height of 1.2m, pinch the top and remove the top advantage of the apple, culti...

Abstract

The invention discloses an apple dwarf cultivation method. The apple dwarf cultivation method is characterized by comprising the following steps of (1) tender tip processing; (2) nutrient bag production; (3) transplanting; (4) pruning and shaping. The apple dwarf cultivation method has the advantages that the tender tips are conducted to root, the apple dwarf reproduction speed is substantially improved, the survival rate and the quality of sprouts are obviously improved, the sprout quickly grows after field planting, the disease resistant capability is strong, trees are dwarfed through pruning and shaping, the operation is simple, the regulation is convenient, the yield of apple seeds is substantially increased, and a good economic and social benefit is realized.

Description

technical field [0001] The invention belongs to the technical field of fruit tree dwarfing, and in particular relates to an apple dwarfing cultivation method. Background technique [0002] The dwarfing of plants is mainly caused by the inhibition of internode growth. Hereditary dwarfing is generally caused by a single gene mutation, but it is generally related to the abnormal metabolism and action of hormones such as gibberellin or plant growth hormone. On d1, d2, d3, d5 and an-1 of corn, short silver bozu (rice variety) of rice. In the dwarfing examples such as morning glory clusters, the use of gibberellin can restore it to normal, because the level of gibberellin in the body is also abnormal, so it can be considered that these dwarf plants synthesize gibberellin in some aspects of the reaction in the body There is a genetic defect that makes the phenotype abnormal. Even dwarfing, which is governed by genes, is light-dependent in its appearance. Certain dwarf varieties...
