Problems solved by technology

However, the coastal saline-alkali soil has sticky structure, poor air permeability, high bulk density, compact compaction, slow water release, high pH value, and strong capillary action, which makes the roots of Berberis purpurea planted in coastal saline-alkali soil very easy to rot and low survival rate; the organic matter content of saline-alkali soil Low, the lack of nutrients makes the excellent landscape effect of purple leaf barberry unable to be fully displayed; the cold wind and low temperature in winter in the northern region greatly increase the difficulty of maintenance and management of purple leaf barberry, resulting in a serious impact on the landscape effect of the purple leaf barberry

Embodiment 1

[0029] The method of the present invention is applied to a real estate landscape improvement project in Tanggu, Tianjin, and the transplanting time is early April.

[0030] A kind of planting method of purple leaf barberry in coastal saline-alkali land, comprises the steps:

[0031] Step 1. Based on the ground where the cultivation bed is located, dig 80 cm vertically downward in the planting area, and lay a 20 cm thick barrier layer in the hollowed out area. The barrier layer is laid flat with a particle size of 7 to 15 mm. Gravel, and the upper surface of the shower layer is covered with permeable geotextile. Around the hollowed out area, plastic film is used to seal it to inhibit the lateral salt intrusion.

[0032] Step 2: Prepare the base fertilizer and sandy cultivation soil with good air permeability one day before the purple leaf barberry transplantation, mix evenly and fill it into the cultivation area. The cultivation soil is made by uniformly mixing garden soil, ri...

Abstract

The invention relates to a method for planting berberis thumbergii in littoral saline-alkali land. The method comprises the following steps of (1), laying a drench isolation layer and a plastic thin film, so as to restrain a saline matter in groundwater from moving up or laterally invading; (2), preparing a base fertilizer and sandy cultivating soil with good air permeability; (3), lifting a seedling, and growing the seedling; (4), shaping and pruning the seedling; (5), managing fertilizer and water; (6), preventing and controlling a disease and an insect pest; (7), protecting the seedling during an overwintering period. The method for planting the berberis thumbergii in the littoral saline-alkali land, which is provided by the invention, is used for planting the berberis thumbergii in the littoral saline-alkali land; the physiological defect of the growth of the berberis thumbergii in the condition of the littoral saline-alkali land is overcome; the landscape effects of the berberis thumbergii in different seasons are promoted; the soil structure of the littoral saline-alkali land is effectively improved; the pH (potential of Hydrogen) value of the soil is decreased; the survival rate and the ornamental value of the berberis thumbergii are increased.

Description

technical field [0001] The invention relates to a method for planting plants, in particular to a method for planting barberry purple leaves in coastal saline-alkali land. Background technique [0002] Purple leaf barberry, Berberis thumbergii, also known as red leaf barberry, is a natural variety of Japanese barberry. Berberidaceae, Berberis genus, deciduous multi-branched shrubs, native to Japan, southeastern my country and the Qinling Mountains. The leaves are dark purple or red, the back color is slightly lighter, with small entire margins, diamond-shaped or obovate, clustered on short branches; young branches are purple-red or dark red, old branches are gray-brown or purple-brown, with grooves and spines ; Inflorescences are solitary or in clusters of 2 to 5, yellow-white umbrella-shaped, with red halo patterns on the edges of petals. Purple-leaved Berberis has beautiful leaf shape and color, round posture, small yellow flowers in spring, and red leaves in autumn. When...
