specific Embodiment approach 1

[0012] Specific embodiment one: a kind of Mandshurica mandshurica in the present embodiment stubble strong seedling cultivation method, it is to carry out according to the following steps:

[0013] One, the selection of strong seedling seedlings: select the seedlings of Mandshurica mandshurica seeding bed for 2 years and ridge cultivation for 1-2 years as the object of flat stubble strong seedlings in the nursery, and carry out listing marks;

[0014] 2. The stubble time is selected in mid-April;

[0015] 3. Stubble of seedlings: use hand shears or olecranon shears to cut the main trunk of Fraxinus mandshurica at a distance of 4 to 5 cm from the ground, and the cutting method is oblique shearing;

[0016] 4. Management after the stubble: Immediately after the stubble, irrigate immediately, and after 1 month of the stubble, perform the bud wiping treatment; the bud wiping treatment refers to: use hand scissors to remove the axillary buds that germinate between the bottom of the...

Abstract

The invention relates to a fraxinus mandshurica stumping strong seedling cultivation method. The fraxinus mandshurica stumping strong seedling cultivation method comprises the steps that nursery stocks planted for two years or ridge cultured for 1-2 years in a fraxinus mandshurica seeding bed in a nursery garden are selected, after winter snow is thoroughly melted in spring, trunks of the fraxinus mandshurica nursery stocks are sheared off at the parts 4-5 cm away from the ground, hand shears good in shearing mouth meshing or specially-made nippers are used, and the using mode of inclined shearing is adopted. Irrigation is carried out immediately after stumping, and the influence of evaporation on the stumped nursery stocks is reduced. After stumping is carried out for one month, bud picking processing is carried out, axillary buds and root suckers germinating between the lower portion of the stump and the ground are sheared off through the hand shears so that nutrition can be concentrated, and the trunks of the nursery stocks are maintained throughly straight. Meanwhile, fertilizer and water management is enhanced, and weeds are removed in time.
