Method for rapidly culturing colorful tree and broad-leaved tree seedlings in container for forestation

Abstract

The invention relates to a method for rapidly culturing colorful tree and broad-leaved tree seedlings in a container for forestation, which comprises the steps as follows: 1, choosing uncontaminated and full smoke tree seeds and steeping the smoke tree seeds in clean water for storing in sand; then after supplementing water to the smoke tree seeds in spring, sowing the smoke tree seeds after 70 percent of the smoke tree seeds open mouth to sprout; 2, bedding and placing the smoke tree seeds in basins; 3, raising seedlings: sowing the sprouted smoke tree seeds in a seedling basin by a spot seeding method with temperature being controlled at 15-28 DEG C and the humidity at 60 percent, covering the smoke tree seeds with sand, spraying the smoke tree seeds and finally covering the smoke tree seeds with a row cover; then performing thinning, watering, dressing, pinching and preventing disease and insect pest; and 4, foresting. The invention realizes the purposes of raising seedling and forestation in the current year to avoid natural drought, prolongs the forestation time, has no growth delaying period, reduces the forestation cost, increases the emergence rate in unit area and improves the survival rate of forestation.

Description

Technical field: [0001] The invention belongs to an afforestation method, in particular to an afforestation method for rapidly growing seedlings of colorful and broad-leaved trees in a mountain. Background technique: [0002] Cotinus coggygria scop., a colorful and broad-leaved tree species, belongs to the genus Cotinus coggygria, 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, is resistant to drought, has thin ridges, and has 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. [0003] The conventional afforestation technology currently used is mainly to select 1-2 year old seedlings, and plant them on the mountain before the seedlings germinate in ea...

AI Technical Summary

Problems solved by technology

[0009] First, the afforestation time is short, and the best afforestation time in spring and autumn is only about 50 days

The second is that the seedling cultivation period is long. With conventional afforestation, the seedlings need to be cultivated for more than one year. The third is that the slow seedling period is long. Generally, it takes 15-25 days in spring and 6 months in autumn before the seedlings start to enter the germination period.

Fourth, seedlings have a long time to resist bad weather, and are prone to water loss to reduce the survival rate. For example, drought and wind, low temperature, sandstorms, and cold spring will directly affect the survival and growth of seedlings.
