Embodiment 1

[0034] The method of the present invention was tested in the apple test and demonstration nursery (34°52'N, 108°7'E) of the modern agricultural demonstration garden in Yangling, Shaanxi. (1) Sowing apple base anvil seeds to obtain base anvil: Choose a non-stubble field, and after deep turning the seedbed ground in spring, open the ditch. The depth of the ditch is 10cm. Use a pipe to pour an appropriate amount of water along the ditch to set up a seeding hole. The sowing holes are distributed as figure 1 As shown, the plant spacing is 20cm, and the row spacing is 40cm+60cm wide and narrow rows. 5 seeds are sown in each hole, then raked flat, lightly compacted with a shovel, immediately cover the sowing ditch with white plastic film, and wait until the seedlings emerge. The seedlings are exposed to the mulch, and a strong seedling is left in each hole, and the white plastic film is removed when the seedling grows to 20cm in height;

Embodiment 2～11

[0041] Change the distribution of seeding holes to make the row spacing, plant spacing and seeding density different, and other operations are the same as in Example 1.

[0042] The specific seeding hole distribution is shown in Table 1, where D5 is the seeding hole distribution in Example 1.

[0045] Note: "+" means the row spacing of wide and narrow rows with wide and narrow row planting.

[0046] The sampling and measurement results of seedlings obtained in Examples 1-11 show that:

[0047] Such as figure 2 As shown, the comparative analysis of the plant heights of the seedlings obtained in Examples 1-11 found that in Example 1, there are 10 plants per square meter, that is, the wide row distance is 60cm, the narrow row is 40cm, and the planting density is 20cm (such as figure 1 Shown), the plant height of the obtained apple seedlings is significantly greater than the planting density great...

Abstract

The invention discloses a high-quality apple dwarf interstock seedling propagation method. The method includes the steps: sowing apple base stock seeds so that base stocks are obtained; grafting dwarf interstocks on the base stocks in the same year; performing root breakage for the base stocks in the same year; stumping and sprouting in spring in the second year so that sprouts of the dwarf interstocks are retained only; grafting variety sprouts on the dwarf interstocks; and in spring in the third year, stumping and sprouting so as to propagate to seedlings. By the propagation method, the produced apple dwarf interstock seedlings are high in quality and good in root systems, and more high-quality nursery stocks can be obtained with less investment, so that income is maximized.

Description

Technical field [0001] The invention belongs to the technical field of fruit tree seedling breeding, and in particular relates to a method for breeding large apple seedlings with high-quality dwarfing interstock. Background technique [0002] The quality of apple seedlings is a key factor that determines whether the newly-built orchard can obtain early production and overall higher economic returns, which is related to the future development of my country's apple industry. With the development of China’s apple industry, the next 5 to 10 years will be a critical period for the large-scale upgrading of China’s apple industry. Therefore, there is a large demand for apple seedlings. At the same time, with the promotion of the intensive and high-efficiency cultivation model of short anvils and dense planting, Higher requirements are put forward for the quality of seedlings (Han Mingyu. 2009. Intensive and efficient cultivation mode of apple short anvils. Friends of Fruit Growers 9:12;...
