A planting method of stachys tomentosa in coastal saline-alkali land

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] Stachys lanata, Stachys lanata, 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...

AI Technical Summary

Problems solved by technology

However, the coastal saline-alkali land has sticky soil structure, poor air permeability, high bulk density, compact compaction, slow water release, low permeability coefficient, high pH value, and strong capillary action, which leads to intensified surface soil salinization.

Therefore, the roots of stachys pilosa planted in coastal saline-alkali land are extremely easy to rot, the survival rate is low, maintenance and management are extremely difficult, and the landscape effect of the garden is seriously affected
