Problems solved by technology

[0008] First, the time for afforestation is relatively concentrated, and the best period for general planting is only about 20 days
The second is that the nursery stock has a long seedling period, and it usually takes 15-25 days for the seedlings to enter the growth and germination period.
Fourth, seedlings have a long time to resist bad weather, such as late spring cold, low temperature, sandstorms, which directly affect the normal growth of seedlings

Embodiment Construction

[0033] Cotinus coggygria (Cotinus coggygria Scop.), a broad-leaved tree species, is a plant of the genus Cotinus coggygria in the Anacardaceae family, also known as Cotinus coggygria, a small deciduous tree or shrub, up to 5-8 meters. The crown is round, and the leaves turn red in autumn. It is an important ornamental red leaf tree species. This tree species grows fast, has a well-developed root system and strong sprouting ability. It is easy to form secondary forest after felling. At present, it is one of the main tree species for barren hill afforestation in North China.

[0034] The low-temperature storage and delayed afforestation method of sumac seedlings is: composed of the following steps:

[0035] ①Low temperature false planting storage of seedlings:

[0036] A: Seedling selection: Choose 1-year-old seedlings with a ground diameter of 1 cm or more to grow robust dry land seedlings.

[0037] B: Early seedlings: When the seedlings do not germinate, the seedlings will...

Abstract

The invention provides a kargeleaf nursery stock low-temperature storage time-delay forestation method, characterized in that: the time-delay forestation method comprises: 1, nursery stock low-temperature temporary planting storage: A selecting nursery stock; B early lifting the seedlings; C controlling the temperature; 2, land-preparation and insemination: A preparing land; B inseminating according to the following steps: a digging hole; b preparing nursery stock; c applying drought-defying water-holding material; d watering and pulping; e putting nursery stock inside; f returning soil; g overlaying mulching film. The kargeleaf nursery stock low-temperature storage time-delay forestation method has the following advantages and aggresive effects: 1 prolonging forestation time by 50day than the conventional forestation time; 2 reducing the seedling recovering period by 15-20day, namely nursery stock budding and growing 3-5day after insemination; 3 new nursery stock safety at spring dryperiod with nursery stock percent and preserving ratio of 98%.

Description

Technical field: [0001] The invention belongs to an afforestation method, in particular to a low-temperature storage and time-delay afforestation method for broad-leaved seedlings. Background technique: [0002] The conventional afforestation technology currently used is mainly to select early spring seedling germination period for uphill planting, that is, from mid-March to late March every year. The main technical measures are: [0003] 1. The afforestation land is mainly arid and sunny slopes of barren hills. [0004] 2. The specification of land preparation is hole-shaped land preparation, and the standard is length × width × depth 40 × 40 × 40 cm. [0005] 3. The seedlings are treated conventionally, that is, stem cutting, branch pruning, root pruning, rooting powder and other technical measures. [0006] 4. Planting method The seedlings are planted by beating and covering with plastic film. [0007] There are problems and deficiencies in the above afforestation tech...
