Embodiment 1

[0020] 1. Selection and treatment of seedlings

[0021] Select seedlings with strong growth, full development, no pests and diseases, meet the design requirements, and are easy to dig and transport as transplant objects. Prune dead twigs.

[0022] 2. Planting hole treatment

[0023] 10 days before the seedlings are planted, water the planting site once, and then deep plow it after 5 days to a depth of about 30cm, and then dry it for 3 days to make the soil within 30cm of the surface dry and loose, and then dig holes and dig planting holes 1m×1m×1m, lay a layer of 10cm thick slag on the base of the planting hole, mix it with pastoral loam: sand: decomposed sheep manure = 1:1:1, fill it into the hole, and pour water in advance to sink it. Soil compacted.

[0024] 3. Shipping and planting

[0025] 3.1 Planting time

[0026] The planting time is late March, when the trees are still dormant and the sap has not yet flowed, which is the best time for transplanting large-scale se...

Abstract

The invention discloses a transplanting method large-size Sabina prezewalskii nursery stocks in a drought area to solve problems of heavy wind and physiological drought due to afforestation in Spring in drought areas. The transplanting method for the large-size Sabina prezewalskii nursery stocks in the drought area comprises the following steps of (A) processing planting caves and (B) lifting seedlings and planting, wherein a planting area is thoroughly watered 10 to 15 days before seedling plantation; deep tillage is applied to the plantation area 5 to 7 days; 10 to 15cm thick of slag is paved on a plantation cave base part; rural soil, sand and decomposed sheep excrement are mixed according to a weight proportion of 1 to 1 to 1 and then placed into the plantation cave; the seedlings are planted between the last ten-day of March to the middle-last period of April; during seedling lifting and transplantation, tassels are provided with soil balls; the diameter of the soil ball is 1 / 5 to 1 / 3; the height of the soil ball is 50 to 70cm; soil is laid 3 to 5cm over original soil during the plantation; plantation soil is filled in a laminated way when the soil is laid; and each layer is 25 cm to 30cm. Soil heaps are provided, straw ropes are winded, soil is backfilled, sand is laid on tree discs and tree crown parts; and six technologies of dense fog irrigation and support fixation are combined, so survival rate of Sabina prezewalskii large-size seedlings in the drought area can be achieved.

Description

technical field [0001] The invention belongs to the field of forestry, and in particular relates to a method for transplanting large-scale seedlings of Qilian juniper. Background technique [0002] Rare tree species is a general term for rare or endangered tree species that are special products in my country, as well as fine tree species that are gradually decreasing although there are a certain number of them. my country's economy is growing rapidly, the process of urbanization is accelerating, and urban and rural greening is in the ascendant. Traditional landscaping mostly advocates the planting of ornamental tree species with beautiful tree shapes, colorful flowers and strong resistance, while often ignoring the economic value of the tree species themselves. Rare tree species have long life, good wood material, excellent ornamental characteristics and strong adaptability. Selecting rare tree species for urban landscaping has incomparable advantages over other tree species...
