Problems solved by technology

In the ridge cultivation of plain apples, if the ridges are raised after planting, the dwarf rootstock section exposed to the ground will be too short, or the cultivars will take root and lose the dwarfing effect of the dwarf rootstock, and the tree will flourish and become an arbor tree. The canopy is closed, the light is poor, the color of the fruit is poor, and the quality of the fruit is reduced; the height of the tree reaches 5-6m, and the pruning, spraying, thinning of flowers and fruit, bagging and fruit picking of the fruit tree are difficult, and it is impossible to perform mechanical pruning and spraying. Does not meet the re

Example Embodiment

[0022] The present invention will now be described in further detail with reference to the drawings. These drawings are all simplified schematic diagrams, which merely illustrate the basic structure of the present invention in a schematic manner, so they only show the structures related to the present invention.

[0023] The preferred embodiment of the method for producing apple seedlings with high and short stocks of the present invention is as follows: the apple seedlings with high and short stocks include high and short intermediate stock apple seedlings and high and short self-root stock apple seedlings.

[0024] If the apple seedlings are produced with high and short interstock, the steps are as follows:

[0025] (a) Before the winter, choose the full sand store of eight-lens crabapple or Pingyi sweet tea seed, and sow after the seeds germinate in March of the next spring, and sown in a ditch. The ditch depth is 4~5cm. The thickness of the fertilizer is 0.5cm, and then the soil...

Abstract

The invention relates to a production method of high dwarfing rootstock apple seedlings. The high dwarfing rootstock apple seedlings comprise high dwarfing interstock apple seedlings and high dwarfing self-rooted rootstock apple seedlings. The height of dwarfing rootstocks of the dwarfing interstock apple seedlings or the dwarfing self-rooted rootstock apple seedlings is increased to 50-60 cm from current height of 20-30 cm, tree planting after ridging is not required, watering is easily performed, and the drought resistant ability is high. By comparison with a method for planting the apple seedlings on ridges after ridging, the survival rate of the seedlings is high. After field planting, 30 cm high ridges are formed in combination of fertilization in the first three years, 20-30 cm high dwarfing rootstocks on the ground are still reserved and take roots, own-root apple trees are grown and grow stably, fruits are high-quality, and the defects of canopy closure of a fruit garden and reduction of fruit quality due to the fact that apple trees vigorously grow after ridging of the conventional dwarfing apple seedlings are overcome.

Description

technical field [0001] The invention relates to a method for cultivating apple seedlings, in particular to a method for producing tall and dwarf stock apple seedlings. Background technique [0002] In the known technical field, modern apple cultivation technology research shows: ridging cultivation can not only avoid the dead trees caused by autumn waterlogging and the serious diseases caused by the weakening of tree vigor, but also promote the root system of apple trees to become a good configuration (see : "Summary of Ridging and Grass Covering Cultivation Techniques for Fruit Trees" - "Shanxi Fruit Tree", 2012, No. 5; "Effect of Ridging Cultivation on Apple Root System Architecture" - "Deciduous Fruit Tree", 2009 Issue 04), thick and large roots Reduced, capillary roots increased, shortened nutrient transport distance, increased cytokinin production, and were conducive to stable tree growth and flowering and fruiting. [0003] At present, the production of dwarf apple se...
