Problems solved by technology

In order to solve the situation that current conventional afforestation technology adopts a single plant species, the survival rate is low and the economic benefit is relatively poor, the present invention proposes a method for cultivating sorbiflora, Quercus mongolica, and Korean pine (grafted Pinus sylvestris) in a nutrient bowl for the northern dry land. The saplings are mixed with coniferous and broad-leaved afforestation methods. The afforestation method is simple, the survival rate of saplings is high, and the economic benefits of afforestation are good. It can effectively improve the barren state of the land. Can produce greater social environmental protection benefits and economic benefits

Embodiment Construction

[0026] Below in conjunction with embodiment the present invention is further described, embodiment: adopt three kinds of nutrient pot seedlings of sorbifolium sorbifolium, Mongolian oak, Korean pine (using Pinus sylvestris as stock grafting) to carry out drought-resistant conifer and broad-leaved mixed afforestation, and it comprises the steps:

[0027] 1. Cultivation of sorbifolium nutrient pot seedlings.

[0028] 2. Cultivation of nutrient pot seedlings of Quercus mongolica.

[0029] 3. Cultivation of Korean pine (using sylvestris sylvestris as rootstock grafting) nutrient pot seedlings.

[0030] 4. For the mixed planting of three kinds of saplings, the afforestation ratio of X. sorbifolium accounts for 30%, the ratio of afforestation of Quercus mongolica accounts for 40%, and the ratio of afforestation of Korean pine (using sylvestris sylvestris as rootstock grafting) accounts for 30%; the density of mixed afforestation: X. sorbifolium 1800×30%+Mongolian oak 2200×40%+Korea...

Abstract

The present invention discloses a drought-resisting coniferous and broad-leaved mixed afforestation method. The method comprises utilizing a plurality of common saplings to mix and match, and performing coniferous and broad-leaved mixed afforestation. The method is characterized in that the employed coniferous and broad-leaved mixed saplings are respectively yellow horn, Mongolian oak and Korean pine (grafted by pinus sylvestris), and the saplings are cultivated by using nutrition pots which are naturally degradable; the yellow horn afforestation proportion is 30%, the Mongolian oak afforestation proportion is 40%, and the Korean pine (grafted by using pinus sylvestris as stocks) afforestation proportion is 30%; and the mixed afforestation density is 2020 strains / hm2. The drought-resisting coniferous and broad-leaved mixed afforestation method using combination of three tree species has the beneficial effects that the drought-resisting coniferous and broad-leaved mixed afforestation method is high in afforestation survival rate, wide in application range, good in practicality and good in economic benefit.

Description

technical field [0001] The invention relates to the technical field of dry land afforestation, in particular to a method for drought-resistant coniferous and broad-leaved mixed afforestation. Background technique [0002] The arid and semi-arid areas account for about half of my country's land area. Drought and water shortage have become the main obstacle to greening vegetation and improving the ecological environment. The dry and water-scarce climate of the desert seriously affects the growth and survival rate of vegetation. The application of drought-resistant afforestation technology is mainly to transform the ecological environment of desertification and afforestation on barren hills. In recent years, drought-resistant afforestation technology has received widespread attention, and it is particularly important to improve the survival rate of afforestation and better control desertification and afforestation on barren hills. Survival rate of afforestation in desert area...
