Embodiment 1

[0023] 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.

[0024] A planting method of stachys tomentosa in coastal saline-alkali land, comprising the steps of:

[0025] Step 1, take the ground where the cultivation bed is located as a benchmark, dig 80cm vertically downwards in the planting area, and lay a 20cm thick barrier layer in the hollowed out area, and the barrier layer is crushed stone, coarse sand with a mass ratio of 3: 1 It is evenly mixed and paved to ensure that the shower layer is paved and solid, and the upper surface of the shower layer is laid with a permeable geotextile. Around the hollowed out area, plastic film is used to seal it to inhibit the lateral salt intrusion.

[0026] Step 2: Prepare base fertilizer and acidic cultivation soil with good air permeability one day before the transplanting of Stachys sinensis. The cultivation soil is evenly mix...

Abstract

The invention relates to a method for planting Stachys lanata in coastal saline-alkali soil. The method comprises the following steps: 1) a rainproof layer and a plastic film are laid to inhibit upward movement and lateral invasion of groundwater salt; 2) base fertilizer and weak-acidity culture soil are prepared; 3) seedlings are lifted and planted; 4) fertilizer and water management is performed; 5) overwintering protection and management are performed. The method is used for planting the Stachys lanata in the coastal saline-alkali soil, the physical defects about growth of the Stachys lanata in the coastal saline-alkali soil are overcome, the saline-alkali soil structure is improved effectively, the pH value of the soil is reduced, and the survival rate and the ornamental value of the Stachys lanata are increased.

Description

technical field [0001] The invention relates to a plant planting method, in particular to a method for planting stachys tomentosa in coastal saline-alkali land. Background technique [0002] Stachyslanata, Stachyslanata, is a perennial herb native to the Middle East, mostly in Iran and Turkey. The whole plant is covered with long white hairs, and the silver-gray leaves are soft and full of texture, resembling rabbit ears, and the cymose inflorescences are red and purple in color. They bloom at the turn of spring and summer, and the main viewing period is winter and spring. A commonly used ornamental variety, it is also quite delicate as a potted plant. Stachys sinensis is resistant to low temperature and drought, prefers high temperature and sunny environment and well-drained soil, and is afraid of waterlogging. The coastal saline-alkali land has viscous soil structure, poor air permeability, high bulk density, compaction, slow water release, low permeability coefficient, ...
