Abstract

The invention discloses a salt pond for an experiment of plant seedlings. Two parallel salt ponds are arranged in each plastic shed with an actual width of 6m, clay common brick bodies are arranged on the inner wall around each salt pond and comprise three layers of bricks from bottom to top, the inner surfaces of the brick bodies and the surfaces of the bottoms of the salt ponds are covered with black film flat spreading layers; and mixed soil of saline soil and common soil, with the thickness of 25cm, is placed in each salt pond, and salt contents of the mixed soil in the salt ponds are respectively 0.01 percent, 0.2 percent, 0.3 percent, 0.4 percent, 0.5 percent or 0.6 percent. The salt ponds has good experiment stability, can obtain one batch of representative data; and the experiment can be carried out around the year, and is little interfered by outside conditions. The salt pond is especially suitable for the experiment of seedlings with the heights of below 1m.

Description

The salt pond is used in the plant seedling experiment

Technical field

The present invention relates to a kind of plant seedling experiment and use the salt pond.

Background technology

In the salt tolerant experiment, the plantation means of plant seedling routine have two kinds, and a kind of is to adopt flowerpot or nutritive cube, because container capacity is little, experimental error is larger; Another kind is directly to be seeded on the solonchak, because external environment changes, the salt content of annual soil is very unstable, and its experimental result does not possess representativeness.

Summary of the invention

The object of the present invention is to provide the plant seedling experiment of a kind of suitable seedling salt tolerant experimental implementation, experiment good stability to use the salt pond.

Technical solution of the present invention is:

The salt pond is used in the experiment of a kind of plant seedling, it is characterized in that: in the overlay film booth of each developed width 6m, set up two parallel salt ponds, and the long 5m in each salt pond, wide 2m, the passageway between two salt ponds is wide to be 0.8m, each 0.6m of peripheral distance booth limit, salt pond; The salt tank depth is 28.3cm; Inwall arranges clay common brick brick body around in the salt pond, and the brick body is comprised of three layers of brick from bottom to top; The basecoat brick is the form of placing vertically, and the long and high face that forms is the bottom surface, and is comprised of four row's bricks from inside to outside; Middle one deck is for keeping flat, and face long and wide composition is the bottom surface, and is comprised of two row's bricks from inside to outside; Last layer is for placing vertically, and the long and high face that forms is the bottom surface, and placement direction is vertical with the placement direction of basecoat brick; All cover black thin film tiling layer at brick body inner surface and salt pond lower surface; Placing thickness in the salt pond is the solonchak of 25cm and the composite soil of common soil, and the composite soil salt content in each salt pond is 0,1 ‰, 2 ‰, 3 ‰, 4 ‰, 5 ‰ or 6 ‰.

The composite soil salt content is that 0,1 ‰, 2 ‰, 3 ‰, 4 ‰, 5 ‰, 6 ‰ composite soil is placed on respectively in the different salt ponds, forms salinity gradient formula salt pond group.

The present invention tests good stability, can obtain a collection of representational data; But experiment is carried out in the anniversary, and it is few disturbed by external condition.This salt pond is particularly suitable for the seedling test of the following height of 1m.

Description of drawings

The invention will be further described below in conjunction with drawings and Examples.

Embodiment

The salt pond is used in the experiment of a kind of plant seedling, sets up two parallel salt ponds in the overlay film booth of each developed width 6m, the long 5m in each salt pond, wide 2m, and the passageway between two salt ponds is wide to be 0.8m, each 0.6m of peripheral distance booth limit, salt pond; The salt tank depth is 28.3cm; Inwall arranges clay common brick brick body around in the salt pond, and the brick body is comprised of three layers of brick from bottom to top; Basecoat brick 1 is the form of placing vertically, and the long and high face that forms is the bottom surface, and is comprised of four row's bricks from inside to outside; Middle one deck 2 is for keeping flat, and face long and wide composition is the bottom surface, and is comprised of two row's bricks from inside to outside; Last layer 3 is for placing vertically, and the long and high face that forms is the bottom surface, and placement direction is vertical with the placement direction of basecoat brick; All cover black thin film tiling layer at brick body inner surface and salt pond lower surface; Placing thickness in the salt pond is the solonchak of 25cm and the composite soil of common soil, and the composite soil salt content in each salt pond is 0,1 ‰, 2 ‰, 3 ‰, 4 ‰, 5 ‰ or 6 ‰.

Can adopt weekly DDS-307A type electric conductivity instrument results of regular determination electrical conductivity, occur that salt content departs from water or salt solution is adjusted.
