Description

Technical Field

[0001] The invention relates to the technical field of alkali-resistant planting, and more particularly to a method for screening alkali-stress-resistant planting. Background Art

[0002] Land salinization is a global challenge facing humanity. my country has large areas of salinized land, primarily distributed in the North China Plain, the Northeast Plain, the inland northwest region, and coastal areas. The survival rate of plants grown in saline-alkali land is generally very low, severely impacting my country's agricultural and forestry production. Salt and alkali can cause two types of damage to plants: first, it is toxic. When plants absorb excessive amounts of sodium or chloride ions, this alters the structure and function of their cell membranes, ultimately causing their death. Second, it increases the osmotic pressure of the soil, creating resistance to plant roots, making it difficult for plants to absorb water, leading to cell dehydration, plant wilting, and ultimately, plant death. The low survival rate of plants grown in saline-alkali land severely impacts my country's agricultural and forestry production. During the planting of seedlings, we often encounter geological soil compaction, poor permeability or impermeability that prevents the roots of the seedlings from taking root, or the planting period of the seedlings is too late, the planting period has passed, drought, little rain, low temperature, low air humidity, and the seedlings are prone to trunk water loss, cracks on the ground surface, and frozen roots, resulting in a low survival rate of seedlings.

In the spring of the second year, backfill the soil and regenerate it. Mix the original soil with the prepared farmyard manure evenly and backfill to half the depth. Build a plastic greenhouse and paint the plastic paper on the top of the greenhouse dark. Dig a cube-shaped planting pit in the greenhouse.

[0009] Step 3: Lay isolation materials that can isolate salt and alkali intrusion on the walls and bottom of the planting pit. The isolation materials are non-woven fabrics, grass fences or biodegradable plastic sheets. Use 5-10 cm long wooden sticks to fix the isolation materials to the walls of the planting pit. Set up a water reservoir around the planting pit with a water injection hole on the top of the reservoir.
