A kind of method of using salt water to transplant tamarisk large seedlings after germination in saline-alkali land

Abstract

The invention discloses a method for transplanting germinated tamarisk seedlings in saline-alkali land by using salt water. The method is to excavate tamarix seedlings, retain thick roots, trim off all germinated branches and leaves on the top of the seedlings and the trunk to obtain the trunk, and align the roots of the seedlings in the same direction. , binding; soak the bundled seedlings in salt water at the planting point for 24-72 h; dig tree pits, sprinkle diamine phosphate at the bottom of each tree pit, and plant a soaked sapling in each tree pit; plant Then pour the salt water at the planting point; cover the entire tree pit surface with plastic film, compact the plastic film on the edge of the tree pit with soil, and perform secondary watering according to the soil moisture content. The method provided by the invention can not only break the seasonal restrictions on the transplanting of tamarix seedlings, but also significantly reduce the consumption of fresh water, reduce the cost of greening saline-alkali land, and can significantly improve the transplanting survival rate of tamarix seedlings, which is beneficial to the original soil vegetation of coastal saline-alkali land. Construction is important.

Description

technical field [0001] The invention relates to the technical field of plant transplantation in saline-alkali land, in particular to a method for transplanting germinated tamarix seedlings in saline-alkali land by using salt water. Background technique [0002] Chinese Tamarix ( Tamarix chinensis ) is a common native plant in coastal saline-alkali land. It is resistant to salt, drought, and flooding, and can adapt to the harsh natural environment in coastal heavy saline-alkali land. Therefore, it is widely used in coastal saline-alkali land vegetation construction and landscaping projects. In recent years, researchers have used the wild variation of Tamarix chinensis to breed a number of new varieties of Tamarix chinensis for landscaping with excellent landscape effects, such as "Tamarisk No. 1", "Salt Pine", etc. Content higher than 8 gkg -1 ) Large-scale promotion in greening. [0003] At present, in order to improve the survival rate of planting, most technicians in th...
