Embodiment Construction

[0022] As shown in the accompanying drawing, a method for planting seedlings in saline-alkali land comprises the following steps

[0023] a. Digging the planting pit 7 on the saline-alkali soil 1 . When digging, the growth of the main root system of the seedlings for 2 to 3 years should be taken into consideration.

[0024] b. Laying the saline-alkali isolation layer 2: laying an isolation material that can isolate saline-alkali intrusion on the pit wall and bottom of the planting pit 7 to form a saline-alkali isolation layer 2. The isolation material adopts non-woven fabric, straw grid or can Degrade the plastic cloth, and use the long wooden stick 3 of 5-10 cm to fix the isolation material on the pit wall of the planting pit 7. The saline-alkali isolation layer 2 can isolate or slow down harmful substances such as saline-alkali intrusion into the planting pit 7, thereby facilitating the normal growth of seedlings. Wooden stick 3 can rot after a period of time, plays the ro...

Abstract

The invention discloses a seedling planting method in an alkaline land. The method comprises the steps of: digging planting pits, laying a salt and alkali isolating layer, laying a water storage layer, laying a percolation layer, backfilling planting soil and cultivating seedlings. By adopting the seedling planting method in the alkaline land disclosed by the invention, the salt and alkali are effectively isolated, drought defying and waterlogging control are realized, the survival rate of the seedling is improved, and the normal growth of the seedlings is ensured; large-area consolidation of the alkaline land is not needed, and only the local plot, in which the seedlings are planted, is needed to be consolidated, so that the seedlings can be planted; and the method is simple, feasible and worthy of popularizing.

Description

technical field [0001] The invention relates to the technical field of seedling planting in saline-alkali land, in particular to a method for planting seedlings in saline-alkali land. Background technique [0002] When there is too much salinity in the soil, salt damage will be formed, affecting the normal growth of plants. Salt-alkali can cause two kinds of harm to plants: one is poisonous effect, when plants absorb more sodium ions or chloride ions, it will change the structure and function of cell membrane, and eventually cause plant death; Osmotic pressure creates resistance to the absorption of plant roots, making it difficult for plants to absorb water, cell dehydration, plant wilting, and finally plant death. [0003] Land salinization is a worldwide problem faced by human beings. There are large areas of saline-alkali land in China, mainly distributed in the North China Plain, Northeast Plain, northwest inland areas and coastal areas. The survival rate of plants pl...
